TRUCK.

Application m dium 17, 1922. Serial No. 568,998.

To all whom it"mayconcern Be it known that I, Soon I. DRESSER, a citizen of'theDo'minion of Canada, residing at Goaticook, in the Province of Quebec and Dominion of Canada, have invented new and useful vImprovements in Trucks, of which the .following'is 1a "specification.

This invention relates :to trucks for handling boxes @and the like iandhas for its fobject the provision .of 2a novelftruck by means .of which .a warehouseman or the likemay handleeven heavy boxes, barrels and crates alone, it being'a feature of thedevice that a jack'means is provided for lifting the box or .otherarticle suflicientlyto effect insertion of the truck nose therebeneath.

An important object is the provision of a truck of'this character having a novelform of jack forming a permanent part thereof for effecting the necessary lifting action.

A further object isthe provision'of a device of this character whichis provided with means hooking 'into'the box or other article for positively preventing lateral displacement thereof during transportation.

Still :another object is the provision of a truck which may be constructed to have either two wheels or a single wheel, depending upon personal preference the action be ing the same in either event.

An additionalobject is the provision ofa device of this character which will be simple and inexpensive in 1nanufacture,-eflicient in use, a great time and labor saver and a general improvement in the art.

With the above an'dother objects and ad: vantages in view the invention consists in the details of constructionato be hereinafter more fully described and claime'd iand illustrated in the accompanying drawings in which: I

Figure 1 is-Ja side elevati'onof one form-of my device showing it disposed adjacentthe end of a box and in initial position,

Figure- 2 is a similar: view showing the box raised onto the truck-and showing the supporting hooks,

Figure?) is anelevation taken at right an les to Figure 2, f r g i igure 4 s a plan view illustrating theattachment er the supporting arms,

Figure 5 is a longitudinal section through another form,

one of the structural elements.

Referring more particularly to the drawings and especially to the first form of my device the numeral 10 designates broadly a frame which might be formed integral or which might be formed of a plurality of sections or elements secured together by any desired means such as riveting or welding. This frame includes a horizontally disposed U-shaped lower ortion 11 from which rises an inverted U- raped vertical portion 12 which has the ends of its arms located intermediate the ends of the arms of the portion 11. The numeral 13 designates inclined braces located near the corners of the upper portion 12 for the purpose of reinforcing the same. The lower portion 11 constitutes the nose of the truck and has its upper surface provided with prongs 1 1 designed to bite into the box, crate, barrel or the like to be handled, so as to prevent slipping' J ournaled beneath the arms of the lower frame member 11 is an axle 15 carrying wheels 16. Extending from the lower frame member 11 at the center thereof is a slotted guide 17 which is formed with bearings engaging the axle 15. The rear side of the bight portion ofthe upper frame member 12 is formed with a bearing 19.

Slidable through the guide 17 and bearing 19 is a vertical rod 20 which has its lower end enlarged to define a foot 21 engageable with the floor or other surface over which the truck is to be moved. Carried by this rod above the frame is a jack consisting of -a :l'ower-sleeve 22 slidably mounted upon the rod and adapted to be held in any adjusted position by means of a set screw 23. Slidable upon the rod above the sleeve 22 is a second sleeve 24 terminating at one side in a tooth v25 designed to bite into the box or crate when a liftin action is to be exerted. Pivotally connected with the sleeve 22 as shown at-26' are upwardly extending links 27 with which are pivotally connected the sides are handle 28 which is pivotall'ycon 29 with the opposite sides ,30 designed to be engaged against the rod :20 at the side thereof most remote from the article to be transported, this yoke terminat ing in loops 31 within which are pivotally engaged eyes 32 formed on the ends of elongated rods terminating in hooks 3% designed to bite into the box or crate at opposite side thereof. 7

In the operation of the device it will be seen that it is wheeled up to a point imme diately against the box or crate as shown in Figure l and the jack structure is adjusted along the rod 20 to bring it at the desired height. The operator then moves the handle 28 upwardly to move the tooth 25 downwardly and then forces the truck against the box or crate to make the tooth bite into the material. A subsequent downward push upon the handle 28 will result in causing the sleeve 24 to move upwardly and cause elevation of one end of the box or crate. During this action the foot 21 of course engages the ground or floor to form a rigid support 1 during the jacking action. When the box has been lifted slightly as above described, it is a simple matter to pull the truck away from the box whereupon the box will swing and drag so that its slightly elevated lower edge will engage upon the frame member 11, the prongs l4 preventing slipping. The yoke is placed in position against the rod 20 with the hooks 34 biting into opposite sides of the box or crate. When the operator then pulls back upon the rod 20 the box-will be lifted from the ground or floor so that its weight will be borne bythe wheels 16; The load may then be easily wheeled or' rolled to any place desired. 1

'In the modified form I have shown the truck as having but a single wheel. In this form of the invention I provide a lower frame member 35 and an upper frame member 36 corresponding to the members 11' and 12 of the first described form. The upper frame 36 is provided at the center of its uppermost portion with a bearing 37 corresponding to the bearing19 but the lower frame is provided with a bearing 38 instead ofthc guide 17 shown in the first form. I

also provide the upper frame 36 with a cross bar 10 provided with a hearing. The numeral 41 designates a caster wheel journaled in a yoke 42 having its trunnion 4:3 journaled through the bearing 38 and'the bearing in the cross bar 40.

The rod 20 of the first described form is replaced, in this instance, by a rod-4:4: which is slidably mounted through the bearing37 and which has its lower end branched to define a U-shaped portion 45 which has its arms slidably engaged through guide brackets 46 projecting rearwardly from the cross bar 39.

The rod 44 carries identically the same jack structure as in the first described form and the same box holding hooks are employed.

In the operation of this form of the device it will be seen that the action is the same as in the first form, the only difference being that in this instance the truck has but one wheel as compared with the two previously described. v

While I have shown and described the preferred embodiments of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:
