UNITED STATES CHARLES T. MCPHALEN, OF LOS ANGELES, CALIFQRNIA.

TRUCK,

Application filed July 23, 1923.

T 0 all whom t may concern,

Be it known that I, CHARLES T. MoPI-IA- LEN, a citizen of Canada, and a resident of Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Truck, of which the following is a specification.

The present invention relates to improvements in trucks and its particular object is to provide a truck that will allow of the con venient handling of a large slab of concrete for constructional purposes. It is particularly proposed to provide a truck of this character that may be pushed under a horizontally disposed. slab, that may be raised to lift the slab off its original support and advanced t0 the building to be erected and that may thereafter be operated to turn the slab into a vertical position at a distance from the axle of the truck. It is further proposed to provide means rendering the truck portable after a slab has been raised into a vertical position. It is further proposed to provide means in combination with this truck whereby the slab, after. being moved into the vertical position can be raised and lowered to suit the requirements of the case, Further objects and advantages of my device will appear as the s-pecication proceeds.

The preferred form of my invention is illustrated in the accompanying drawing in which Figure 1 shows a side View of my truck, Figure 2 a top plan View of the same, Figure 3 a side elevation with the bed of the truck lifted to a vertical position, Figure 4 a perspective view of the front end of a frame member` and Figure 5 a perspective view of a handle for operating a ratchet. While I have shown only the preferred form of my invention I wish it to be understood that various changes and modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

The axle (1) .is supported in two wheels (2) and has a drum (3) disposed on its central portion. Along frame (4) corresponding preferably to the size of the slab to be transported consists of the longitudinal frame members (6) and a plurality of trans-y verse frame members (7). A short frame (8) of similar construction is pivotally secured to the axle by means of bearings (9) so as to freely swing on the same, with the rear end of the short frame exceeding in Serial No. 653,278.

length the front end of the same. considerably as shown in the drawing. The long frame which is of the same width as the short frame is adapted to lie on the same and has bractets (11) depending from an intermediate portion of its front end adapted to pivotally engage the front end of the short frame by means of the pin (12).

1n the rear end of the short frame is mounted, on a shaft (13), a sheave (14) adapted to be rotated by means of a worin gear (16) disposed on the outside of the frame. This worm gear is engaged by a worm (17) supported in bearings (18) and adapted to be driven by means of a crank handle (19) whichengages the worm means of a universal joint (21) which allows the position of the crank handle to be changed in case the width of the slab to be carried by the long frame exceeds the width 'l of the latter without interfering with the operation of the worm gear. Two cables (22) are secured to the front end of the long frame as shown at (23), passed around the drum (3) and secured with their othel ends to the sheave (14) so that when the latter is turned in the. proper direction the rear end of the short frame will be swung downwardly while at the same time downward pull will be exerted on the front end of the long frame. It should be noted that: the weight of the two frames is distributed in such a manner that during the beginning of the operation the lowering of the rear end of the short frame will cause the long frame to be lifted merely without changing its horizontal position due to the fact that Athe rear end of the long frame as counted from the pivot (12) is considerably longer than the front end and is adapted to thus balance the pull exerted on the front end by the cable (22) until the rear end of the short frame reaches the ground surface as shown in dotted lines in Figure l., As soon as this dotted line position is reached a further turning of the sheave (14) will cause the long frame to tilt forwardly and to gradually assume thevertical position shown in Figure 3 while at the same time the two wheels are lifted off the groundt The front end of the long frame is provided with two wheels (24) rotatable on short axles (26) and the rear end of the short frame is provided with similar wheels (27) on the axles (28),. As soon as the front end of the long ('27). The front Wheels (24) are adapted to be actuated by .inea-inset.ratchets (29) operated by the paivl (31') on a handle (32') A which allows the position of the Whole .de-

The liront end oli the long vframehas clips (31) extending inwardly with arms pivoted on the same Which-latter arms have Wheels mounted in their free ends. yThese wheels are disposed in the plane of the upper frame and may be projected to extend beyond the Wheel (24) by means ol the toggle joint comprising two lengths l"(56)"engaging intermediate portions ol the arms Y(32) landengaged attheir v tree ends bythe 'threaded member' ('87) which latter 'may be ,actuated torl longitudinal adjustment by a nut held against longitudinal inotion'by Washers (41 .bearing `on trans- ,ifersetrjame members-(i). `It will be seen that when the Wheels are projected-flie- Vyond the Wheels (24) Vthey will take'the load and iriill allow vtheliront end of the device to be moved laterally.

-Arbraeket` ('42) is mounted in the'r'ront end of each longitudinal frame member and provided with a shortftlange (43)' for holding theslab When the upper frame is turned into a verticalposition. 'The brackets are slidvable in groove (44) in the longitudinal trame members (-6) and are oon'ined-in-the -grooves (44) bythe slats (4(6). The extrerne ends of -the two brackets are enraged by cables -orropes (4:7)passing over 'sheaves (48) and (49) lto be engaged by an eye-bolt (51) VWliichllatter maybe pulled upwardly-by means of a nut (-52) bearing Von afivasher (53) Which 4latter, is seated vagainst `one of the transverse traine members (7).
