A trailerable engine housing 10 for a heat and noise emitting engine 68 is provided, formed of an open topped container having pyramidally shaped end walls 22, 24, side walls 14, 16, and a base plate 42. The open topped container is divided into two separate enclosures by an enclosure baffle 58. A pair of vent panel 28, 30, are held in angled spaced relationship to the pyramidal side edges of the end walls to form an air induction vent hole open to one enclosure and a hot air exhaust hole open to the other. Inducted air is transferred from one enclosure to the other through an enclosure baffle vent hole. Sonic energy may not pass through either the induction air or the hot air exhaust vent holes without first being reflected off a surface within the engine housing.

A motar mixer driven by a hydraulic pump and motor which are powered by an gasoline engine. The mixer frame is configured as a trailer to facilitate transport of the mortar mixer. The trailer frame is further adapted so that the frame members form a fluid reservoir for the hydraulic fluid for the system. A tubular steel frame assembly, is manufactured so that the inner chambers of the frame members are in fluid communication with one another. A reservoir dam is placed inside the horizontal trailer frame member to provide a crush zone for eliminating risk of damage to the reservoir in the event that the weld that secures the front trailer frame member to the horizontal trailer frame member fails or fractures. Cooling of the hydraulic fluid and engine/pump compartment is accomplished by creating a flow of ambient air through a duct which passes along the side of and is affixed to the horizontal trailer frame member, the flow of air being generated by a squirrel cage fan which is attached directly to and rotates with the output shaft of the hydraulic pump.

An automatic variable speed centrifugal clutch belt tightening assembly is characterized by even transmission of rotational drive to a pair of belts and includes a rotating spindle and clutch plate having an adjustable centrifugally operable belt tightening mechanism. The belt tightening mechanism includes a clutch drum and a spacer which define recesses for receiving the belts to be driven. The spacer is mounted on the spindle by a bearing assembly affording free rotational and limited longitudinal movement relative to the spindle. As the spindle rotates, the clutch drum presses the spacer against a flange of the spindle to evenly drive the belts while compensating for differences in belt size.

A concrete finishing machine having a rotatable trowel blade assembly and a mechanism for controllably adjusting the pitch of the trowel blades relative to a wet concrete surface on which the blades rest. Manual pivoting of a control lever controllably adjusts the trowel blade pitch and, in doing so, automatically increases or decreases the amount of blade surface contacting the concrete surface, and correspondingly lowers or raises the machine relative to the surface. The contacting blade surface supports the machine's entire weight. A special counterbalancing apparatus that includes, for example, a compressed coil spring, biases the control lever so as to compensate for the machine's weight and permits an operator to adjust the blade pitch with substantially less force than otherwise would be required.

A pump is provided for circulating drilling fluid and the like into a well during a well drilling process. The pump comprises a pair of double-ended piston assemblies hydraulically reciprocated in opposite directions by a common hydraulic drive arrangement, wherein each piston assembly has a relatively large piston at one end and a relatively small piston at an opposite end. The various pistons reciprocate within appropriately sized cylinders each having a working end with a one-way intake valve through which drilling fluid is drawn from a supply tank and a one-way discharge valve through which drilling fluid is discharged to the well. These intake and discharge valves, or other flow control valves in an alternative form of the invention, can be set appropriately for pumping drilling fluid at a relatively high pressure and low flow rate using only the smaller pistons or for pumping drilling fluid at a comparatively lower pressure and higher flow rate using only the larger pistons, wherein drilling fluid is continuously circulated by the unused pistons through the unused cylinders to maintain fluid flow thereby preventing settling of particulate entrained in the drilling fluid within unused cylinders. Still further, the various valves can be set for pumping drilling fluid at a further reduced pressure and still higher flow rate using the large and small pistons in combination. In other alternative embodiments of the invention, the discharge pressure of the drilling fluid can be intensified by appropriate routing of a portion of the drilling fluid in a manner to assist driving either the large or small pistons.
