WALTER J. MCCOY, OF SOUTH OMAHA, NEBRASKA, ASSIGNOR 0F ONE-HALF TO JOSEPH H. KAPIE'IZ, OF SOUTH OMAHA, NEBRASKA.

TRUCK.

To all whom it may concern:

Be it known that I, WALTER J. MoCoY, a citizen of the United States, residing at South Omaha, in the county of Douglas and State of Nebraska, have invented new and useful Improvements in Trucks, of which the following is a specification.

The present invention has reference to improvements in trucks, and it comprehends generally, the production of an implement of the type specified which, with certain necessary changes, may be readily and effectively used for handling either burned or green brick, boxes, and barrels.

Briefly described, the improved truck comprises a wheeled frame to which is pivotally connected a pair of load-supporting arms, these arms varying somewhat in their construction to conform to the character of the load with which they are to be used, and having associated therewith a cushioning device composed of main and auxiliary springs. There is also pivoted to the truck frame a lever designed to operate either a slide or a clamp, according as one form of arm or an other is to be employed. With this lever, there is associated a tripcontrolled latch, by means whereof it is retained in adjusted position.

A. structural embodiment of the invention is illustrated in the accompanying drawings, wherein,

Figure 1 is a perspective view of the improved truck when used for handling burned brick, Fig. 2 is a longitudinal sectional view showing the truck in unloading position, Fig. 3 is a front elevation of Fig. 1, Fig. 4 is a detail view of the pallet carried by the load-supporting arms, Fig. 5 is a longitudinal sectional view of the form of truck employed for handling boxes, Fig. 6 is a front elevation of the truck shown in Fig. 5, Fig. 7 is a perspective view of the lever operated slide, Fig. 8 is a fragmental view of the lower end of one of the load-supporting arms, showing the lifting plate attached thereto, Fig. 9 is a perspective view illustrating the arms employed for handling green brick, Fig. 10 is a detail view of the pallet utilized in connection with the arms shown in Fig. 9, Fig. 11 is a perspective view showing the drums employed for handling barrels, and showing also the clamping device used in this form of the inven- Specification of Letters Patent.

tion, 12 is a fragmental detail view of Fig. 11, Fig. 13 is a detail view of the cushioning device, and the operating lever associated therewith, said device being shown partly in vertical section, and said lever be ing illustrated in connection with its latch and trip, Fig. 14 is a plan view of the upper plate of the cushioning device, and Figs. 15 and 16 are detail views respectively, of the latch and trip.

Referring to said drawings, 1 designates the axle, 2 the wheels, mounted on the ends thereof, and 8 the truck frame. Said frame comprises a pair of inclined side beams 4, connected at their upper or rear ends by a cross-bar 5, and adjacent their lower or front ends to the axle, a pair of horizontal beams 6 likewise connected at their front ends to said axle, and terminating at their rear ends in handles 7 and a pair of vertical supports or legs 8, said legs being connected at their upper ends to the inclined beams and intermediate their ends to the horizontal beams. The lower ends of the legs are connected by a cross-beam 9. If desired, the beams 4 may be strengthened by means of reinforcing strips 10 suitably fastened to the sides thereof.

The cross bar 5 has its ends projecting through openings formed in the inclined beams 4, accidental displacement of said beam ends being prevented by means of nuts 11 threaded upon the bar ends. To this bar there is also pivoted a pair of loadsupporting arms 12 which are arranged between the beams 4 and are maintained in proper position with reference thereto and to each other by .tubular spacers. These spacers are loosely fitted upon bar 5, the central spacer 13 located between the two arms 12 being considerably longer than the two end spacers 14 between said arms and the adjacent beams. To the lower portion of each supporting arm there is secured an L-shaped bracket 15 which has its longer arm 16 resting upon the upper plate 17 of the adjacent cushioning device 18. These cushioning devices, two of which are employed, each include, in addition to the upper plate 17, a lower plate 19 pivotally mounted on the axle 1, said plates being connected by a series of bolts and yieldingly forced'apart from each other by means of expansible coil springs encircling said bolts.

In' the construction illustrated three bolts are made use of, the two end bolts having their headed upper ends received in seats 21 formed in plate 17, and their lower ends extending loosely through openings 22 formed in plate 19, the last-mentioned ends of said bolts carrying nuts or the like which are held against the under face of plate 19 by the tension of springs 23. The central or main bolt 24 of each device is secured at its lower end to plate 19 and projects at its upper end through an opening 25 in plate 17 and a slot 26 formed in bracket-arm 16. This bolt is encircled by a spring 27 which terminates at its upper end short of plate 17, and hence is acted upon only after the springs 23 have been compressed to a predetermined extent.

hen the truck is to be used for handling burned brick, as in the case in the constructions shown in Figs. 1 to 4, a sliding pallet 28 is employed. This pallet is operated by a lever 29, hereinafter more fully described, and is designed to support the bricks, which are initially piled thereon and against a supplemental pallet 30, (Fi 4) adapted to be carried by the supporting arms 12, said pallet 30 being provided with spaced ribs 31 whereby it is enabled to be positioned with respect to said arms. The main pallet 28 is provided with a pair of grooved guides 32 in which are received tongues 33 secured to the lower ends of the beams 4. Pallet 28 is also provided with a centrally located pair of ears 34 between which the lower end of lever 29 is pivot-ed, said lever being fulcrumed upon a pin 35 that connects the apices of a pair of angular brackets arranged in' spaced parallel relation. The free ends of the front or shorter arms 36 of said brackets are attached to the axle 1, and those of the rear or longer arms 37 to the cross-beam 9, the latter arms being further connected by a cross-pin 38 located intermediate the ends thereof. This pin is designed for interchangeable engagement with the teeth 39 formed in the lower face of a catch 40 pivoted at its front end, as at 4 to lever 29 directly adjacent the fulcrum pin 35. To release the catch from such engagement, there is provided a cam-shaped trip 42 pivoted at 43 between the lower ends of the bracket arms 37 and provided with an operating portion 44. The rear end of catch 40 rests upon the edge of this trip, and in consequence thereof a rotary movement of said trip in a counter-clockwise direction will result in raising said end and, thus, in disengaging the trip tooth from pin 38, the movement of the trip being effected by the pressure of the operators foot forwardly against the projecting portion 44.

In operating the structure above de scribed, the pallet 28 is moved forwardly into position to receive the bricks, which are from the handles.

then fitted thereupon and against the pallet 30 in the usual manner, the last mentioned pallet having been positioned upon the supporting arms 12 prior to the commencement of the loading, as will be apparent. At the conclusion of the loading operation, clownward pressure is applied to the handles so as to swing the supporting arms into horizontal position, during which time the load will be taken up first by the springs 23 and then by the main springs 27 of the cushion ing devices, the action of the latter springs commencing after the auxiliary or light springs have been compressed to a predetermined degree. On reaching a horizontal position, the load will be supported directly by the main springs and held in a state of balance by the auxiliary springs, which latter are arranged at opposite sides of the main springs, as shown. The loaded truck may then be readily wh eled to the point where the bricks are to be dumped, since the weight of the load is entirely removed lVhen the unloading point is reached, the truck is again tilted to bring the supporting arms into vertical position, after which the trip 42 is operated to release the lever catch, and the lever pushed forward to withdraw the sliding pallet. The bricks will then be deposited upon the ground in a regular uniform pile.

Practically the same structure is employed when boxes are to be handled, the pallet 28 being replaced by the sliding fork 45 shown in Fig. 7. The guides 46 and ears 47 on said fork are substantially identical with the corresponding elements provided upon pallet 28 and no additional description is therefore necessary. The lower ends of the supporting arms, are, however, provided with L-shaped lift-ing plates 48, the feet of which have beveled front edges. Tn operating this form of truck, it is wheeled close enough to the box to enable the sharpened feet of the lifting plates to be inserted beneath the bottom of the box, the truck having previously been shifted to bring the support-ing arms into vertical position. (See Fig. 5). The handles are then swung slightly backward, to raise up the end of the box engaged by the lifting feet, whereupon the lever 29 may be operated to force the fork beneath the box, the supporting arms being then lowered into horizontal position.

lVhen green brick are to be handled, the lifting plates are replaced by angular bars 49, the elongated forwardly extending arms of which are designed to project beneath an elevated pallet 50, (Fig. 10) supported upon feet 51.

The pallet 30 is likewise employed in this form of truck in the same manner and for the same purpose as shown and described in connection with the form of truck used for handling burned brick, (Figs. 1 to 4,) in view of which fact further illustration of said pallet 30 is considered unnecessary.

WVith reference to the supporting arms shown in the first three forms of the invention, it may be stated that two constructions are possible. That is to say, a single pair of arms will answer all purposes by providing for the detachable connection of the lifting plates 48 and bars 49 thereto, so that said arms may be used without lifting devices of any character as is the case when burned brick are to be handled. This form also presupposes a detachable connection for the fork 45 and pallet 28 to the operating lever. On the other hand, it may be considered desirable for some purposes to provide a separate pair of arms for each separate use for which the truck is intended. In such case, it becomes necessary to completely withdraw the cross bar 5 and then attach thereto the particular pair of arms to be employed.

Then the truck is to be used for handling barrels, the supporting arms above referred to are replaced by the pair of arms 52 shown in Fig. 11, said arms being connected by a series of spaced arcuate supporting hoops 53 and being provided with transverse perforations 54 for the cross bar 5. To the lower end of each arm 52 is fastened a bolt or pin 55 upon which is pivoted a block 56, these blocks being designed to carry the arcuate barrel clamps 57 that are secured thereto by bolts 58. The rear ends of clamps 57 are connected by links 59 to the lower end of the operating lever 29. In operating the truck, the supporting arms are raised into vertical position, after which the truck is wheeled sufficiently close to the barrel to permit the latter to enter between the clamps 57 which are in open position at that time. The operating lever is then pushed forward, whereupon the clamps will be moved inwardly and tightened against the barrel.
