Specification of Letters Patent.
Patented Mar. 19, 1918.
Application filed October 17, 1917. Serial No. 197,011.
To all 'whom t may concern:
Be it known that I, IRA A. WEAVER, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Hoists, of which the following is a specification.
My invention pertains to hoists, or elevating or lifting appliances in general, but has special reference to devices of this character particularly adapted for use in association with automobiles, although its employment is not necessarily limited to such line of work.
One object of the invention is to provide an appliance of this type which will obvi` ate'the necessity for a pit which experience has demonstrated is objectionable for the reason that dirt, grease, and gas accumulate in it, thus 'rendering it dangerous on account of explosion and fire, as well as unsightly. The improved hoist, therefore, is so designed, constructed, and operated, as to permit the work ordinarily requiring a pit to be accomplished with ease and despatch, but without necessitating a pit construction. In other words, the hoist is adapted to raise the automobile so that work beneath it can be readily and efficiently performed.
A further feature of the invention is that the hoisting mechanism forming a part thereof may be used either to raise some .part of the automobile, suchas the body orV engine, or may be alternatively employed for elevating or adjusting the hoist itself.'
Another salient object of the invention is to so shape the hoist framework and so mount it on wheels thatit can beeasily operatively associated with kan automobile, even though the latter ma be one of a row arranged close together. tated differently, the appliance occupies but little space and is .easily moved about from one car to another although they may be in somewhat inaccessible places. Y
In order that those skilled in this art may have a full and complete understanding-of the invention and its various benefits and advantages, I have illustrated a preferred rand desirable embodiment of the same in the accompanying drawings, forming a part of this specification, and throughout the various views of which like refer- .ence characters refer to the same parts.
parts being viewed in the direction indicated by the arrows.
Referring to the drawings more in detail, it will be observed that the appliance comprises two spaced parallel frames 10 and 11 (Fig. 1), slidinglv associated with a transversely-arranged,l connecting, inverted, U- shaped frame 12. Each of the frames 10 and V11 comprises aV bottom angle-bar 13V (Fig. 2)
equipped at each end with a suitably mounted caster wheel 1-1. Rising from this bottomr bar 13 is a Vframework composed of a oentral upright plate 15 riveted or bolted at its lower end at 16 to the vertical flange of the angle-bar 13. At its upper end such plate .15 isv fastened by one or more bolts or rivets to thetop horizontal portion 17 of a bent bar having two oppositely- inclined portions 18 and 19 .fastened at their lower ends at 20 and 21 to the same flange of the bar 13 that the plate 15 is secured to. The two portions 18 and 19 are connected together by an intermediate horizontal bar 22 which at its center portion, is provided with a bent strap 23 fastened thereto in vertical register with a similar bent strap 24 secured to the part 17. The transverse connecting frame 12 of in verted U-shape comprises a bent channelbar 25 strengthened at its upper part on each side by deeper or wider U-shape plates 26, 26, bolted or otherwise suitably secured to the outstanding flanges of such bar. The two vertical legs of this connecting frame are slidingly received in the socket memjustment, as may be required from time to time. In order. that such frame may be suitably held or maintained in its various adjusted positions of elevation, the webs of the lower portions of the two parallel legs of'such frame have apertures 27, 27, adapted to receive holding pins or bolts 28., 28, each of which extends through registering holes 29 in the strap 24, 3() in the upper end of the bar 15, and 31 in the crosspiece 17 of the connecting frame'near its ends, or either chain may be shiftedso as to coperate with the substantially centrally located pulley 44,' the association of the chains with the pulleys depending, as will be readily understood, upon the nature of the work to be done.
Obviously, by turning the handle, the chain 37 may be wound upon or unwound from the drum, thus modifying its effective length and causing the ascent or lowering of the chains 39' and' 40 and the piece of work to which they may be attached, or as explained above, either chain may be used singly with the middle pulley. The worm, of course, acts as a lock for the worin-wheel and drum, thus preventing unintentional action of the chain by reason of unlocking.
In order that the appliance may be quickly and easily adjustable as to height, sor that it can be used with automobiles, especially those with closed bodies, of dif# ferent heights or dimensions, each leg of the central frame is provided with a pulley 45 andeach side-frame at its top has a loop or link 46 into which the members 41 are adaptedV to hook with the chains passingbe.- neath such pulleys,y as` shown in Fig. 3. By thus making the chain connections so as to support the" central transverse frame, the pins28 may be removed and the frame adjusted either up or down by turningw handle 34, whereupon the pins may again be inserted in the registering apertures and hold the frame in adjusted position. The loops or bentstraps 23 and 24 guide the legs of the frame during such manipulations and securely hold the three parts of the complete frame together. rlhe adjustment having been effected, the hooks 41 are released from the loops or links 46 and then the chains and hoisting mechanism are ready for the performance of' their usual work.
1n some cases it may be desirable andV advantageous to equip such a hoist appliance with a bent rod or bail 47 rockingly mounted at its opposite ends in bearings 48,48, on the bars 13, 13, and assisting in preventing the side-frames 10 and 11 from spreading apart. When swung up as shown in dottedlines in Fig. 2, such rod or bail may be employed as ahandle for moving the hoist from one position to another, but when not so used, such bail rests on the floor as indicated in full lines, and forms no obstruction to the automobile with which the hoist may be used. Such automobile may be easily rolled over it if occasion requires. 1t is to be understood that the employment of such a lower cross-connecting member is quite optional, as the appliance canV easily be made streng enough without its presence.
To those skilled in this art it will be appreciated that many minor mechanical changes maybe made in the structure presented herein without departure from the substance and essence of' the invention and Y without the sacrifice of; any of its substantial benefits and advantages.
