A tire lift/carrier unit has a sheet metal housing forming an enclosure and having parallel spaced walls supporting a rotatable shaft which supports a rotatable spool formed by a set of sheet metal plates. A flexible cable has one end connected to the spool and its opposite end connected to a tire support member, and the plates are spaced closely together to define a track slightly wider than the cable so that the cable wraps on itself in a spiral overlapping manner. A ring gear is mounted on the spool and surrounds an internal drive gear supported for orbital movement by an eccentric cam member rotably supported by the shaft. The cam member is rotated by the shaft through a spring biased slip clutch mounted on the shaft.

A tire lift/carrier unit is mounted on a vehicle body and has a depending cable connected by a latch device to a fitting which supports the hub of a spare tire and wheel assembly. When the tire assembly is elevated by the unit to a stored position, the latch device is received within a holder also secured to the vehicle body. In event the cable fails to hold the spare tire assembly in the stored position, latch bolts spring outwardly from the latch device and engage the holder to prevent dropping of the tire assembly. The holder may be formed of adjustable or telescopic sections which may be tubular for enclosing the latch device.

A universal joint comprising a pair of coupling devices each including a generally cylindrical portion having an extension at one end including a plurality of projections which are outwardly divergent and circularly spaced. Such projections of each coupling device are arranged to have their successively adjacent side surfaces formed to define therebetween spaces the bounding sides of which are divergent. In the assembled relation of the coupling devices the projections of the respective extensions thereof are relatively rotatively displaced and interfit and the projections of one thereof are respectively projected in, through and beyond the spaces defined between the bounding sides of the projections of the other of said extensions. The projections of said coupling devices as so interrelated are formed and spaced to variously have a slip, sliding and longitudinal and lateral overlapping relation during use of the joint of which they form a part the nature of which is such to induce a self balancing and biasing of the parts of the joint to the positions in which they are set for use thereof.

A pneumatic, syphon type apparatus particularly advantageous for dispensing and applying viscous materials in a spray form features, in a preferred embodiment, a throwaway eductor assembly which slip fits to the delivery end of a tubular structure adapted for connection to and delivery therethrough of air or other gaseous fluid under pressure. The eductor assembly comprises a tubular adapter extended at one end by an eductor tube and at the other by an applied nozzle and a syphon tube connected therewith to open to its interior adjacent the nozzle and at right angles thereto. In use of the apparatus the syphon tube is introduced to a body of the material to be dispensed as the end of the adapter including the nozzle is releasably coupled to the discharge end of the tube which is connected to a source of air under pressure. In preferred embodiments the tubular structure for delivering air, under pressure, to and through the nozzle of the eductor assembly mounts apparatus for the quick releasable coupling thereto of the container of a quantity of the material to be dispensed and applied by way of the eductor assembly in a spray form. The apparatus enables a quick substitution of one eductor assembly for another and one container of material for another.

Torque wrench

A torque wrench, basically exemplified by a torque beam having a driver at one end, a grip at its other end and apparatus associated with said driver and beam providing an observable read-out of any torque that may be developed during use of the wrench, particularly distinguished by a system for defining a prescribed torque limit in use thereof having means associated therewith for producing a highly distinctive alarm signal the nature of which is such to produce an instantaneous torque limiting response of the user at precisely that time the level of the torque applied to said beam reaches said prescribed limit. In a preferred embodiment the system for producing said signal is located in connection with a housing which is releasably based on and secured to said beam immediately of its grip, the means through which the signal is triggered is functionally related to a portion of said read-out apparatus and the alarm signal is preferably provided by a source of light and optionally by a source of sound.

The illustrated embodiment which is in the form of a winch (or hoist) comprises a reel including a spool and embodying a portion thereof through which it may be driven for its raising and lowering functions. The reel mounts in bearing relation to a drive shaft between parallel relatively closely spaced side walls of its housing. This embodiment features an overload clutch including a drive plate mounted for rotation with said shaft within said housing. The drive plate nests within a shallow cup-shaped plate firmly and resiliently coupled by springs, parts of which have an interfit relation with portions of the bounding wall. Upon rotation of the shaft the nature and direction thereof is transmitted through the clutch and successive drive transmission elements to the portion of the reel provided for this purpose. The spool includes a narrow track the base of which is formed in a special arcuate pattern, an interior pocket which is formed to anchor one end of a cable and a restricted passage leading from the pocket, to open from said base, the line of which is lateral to a line radial to the spool. The form of the base and the track dictates a natural stress free coil of the cable on the base and smooth extension of the cable from the winch housing. Additional features include a guide system for the cable providing not only a minimalizing of the wear, tear, and stress normally incident to the use of such apparatus but facilitating a most efficient use thereof where the winch is offset from the applied load. Controls are incorporated through the medium of which the rotation of the reel may be interrupted before the cable is completely unwrapped from the base of the spool.

The invention relates to a new and improved tire lift/carrier featuring a reel assembly comprised of a rotatable spool formed of thin metal plates abutted one to the other in a side by side relation, a portion of which plates defines a cavity in which one end of a line is held captive, the other end of which line is adapted to extend to releasably connect to a load which places a tension on this line in use. In the preferred embodiment described the spool has a single track within which the single line in connection with the spool is constrained to wrap directly on itself. The connection of the line to the spool is such that the spool may be rotated in either of opposite directions and in either case the line will wrap smoothly on itself. In the preferred embodiment illustrated the spool has a press fit gear through the medium of which it is driven in either of its opposite directions of rotation. This press fit gear is illustrated as driven by an orbiting gear under the influence of the shaft about which the spool rotates. In a particularly preferred embodiment the drive mechanism for the spool includes a simple torque limiting device serving as a protective medium for the reel assembly in use.

A coupling element comprising elongate thermo-plastic strip material structured to provide that, on application thereto of heat in the range from about 300.degree. to about 500.degree. F. the outer portion thereof becomes fluidly adhesive, and is particularly adapted thereby to quickly form a ready bond and a clean seal between different materials, especially between glass and metal parts. While under the application of heat in the range specified, the outer portion of the element becomes fluidly adhesive, the inner or core portion of the element retains, as originally provided, an essentially stable form which accommodates and conforms to the contour of an applied load. On self cooling in place the strip coupling device provides a uniquely complete and extremely strong bond and seal between parts of unlike materials. In preferred embodiments and applications the invention provides for an improved installation of a window, windshield or like unit. Elements of the invention are particularly distinguished by their reversibility. Once an element is in place and serving as a bond, it need merely be subjected to heat in the prescribed temperature range of 300.degree. to 500.degree. F., under which conditions the outer portion of the element becomes fluid while the stability of the core thereof is maintained. This enables that the element may be quickly and easily removed from between the parts for which it formerly served as a bond.

A coupling device particularly advantageous for use in connecting parts of unlike material comprising a flexible strip formed element having a resilient core. In preferred embodiment this core is covered or substantially sheathed in an envelope which is preferably of non-porous flexible material capable of heat transfer, the outer surface of which mounts a pressure or heat sensitive adhesive. The strip body is characterized in one form by the feature that on application of a predetermined range of heat it will self adapt in form and/or contained volume to the load of contacting parts, in the process of which the adhesive will bond to such parts and the body of the strip will form a seal between the parts in contact, irrespective of irregularities in the contacted surfaces. An aspect of the invention of considerable importance is the concept of controlled flow so that coupling devices, on deformation thereof under load, will inherently seek the proper direction of flow, self-dispersing in a manner to minimize and avoid surface contamination and effect optimal positioning of adhesive parts.

This invention relates to a reversible hand operated device having equal utility as a hoist, winch or puller. It features a unique finger operated control housed in an opening of the operating lever of said device, which control may be smoothly shifted from one position to another to dictate either the raising or lowering function of the device as a hoist or an application of tension to or a release of tension from an applied load when the device is used as a winch or a puller. Preferred embodiments of the invention also feature a strong light weight frame comprised of opposed plates the major extent of which are held in a spaced parallel relation by reason of their adjacent ends being turned over, overlapped and simply interconnected to form flats to either end of the frame. The frame is distinguished by bridging pivot means one of which mounts the cable drum and operating lever of the device and another of which pivotally mounts a retainer pawl for engagement with a ratchet in connection with the drum. The invention also illustrates improved let down mechanism selectively governed by a simple slide, the position of which dictates the increment of let down on each cycle of the operating lever of the device.
