LIFTING JACK FOR VEHICLES..

Specification of Letters Patent.

Patented Feb. 7, 1922.

Application filed April 28, 1921 Serial No. 465,205.

To all whom it may concern:

Be it known that I, JOHN M. *ToerAs, renty of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or dis covered certain new and useful Improvements in Lifting Jacks for Vehicles, of which improvements the following is a specification. v P

My invention resides in a device for liit ing the wheel. of an automobile free of the ground as occasion may arise. It is intended primarily for application to and use with automobiles, where it is serviceable when occasion arises toremove or replace a-tire. The device, when applied, is brou 'ht into play by the travel of the car itseli which ordinarily is effected under the power of the engine, and the advantages attained are simplicity, strength, cheapness, facility of app ication and removal. There are incidental advantages, over and above the achievement of the primary purpose; these will be mentioned in the sequel.

In the accompanying drawings, Fig. I is a View in side elevation of an automobile wheel with the appliance in which my inhention resides in place upon it; Fig. II is a ragmentary view, and

of the wheel; Fig. IV is a View in perspective of that member or element of the device which in ,theordinary service of the automobile is removable and. replaceable as occasion arises. Fig. V is a view corresponding to Fig. III and illustrating a modification; Fig. VI is a View in elevation of the foot member of the applianceitself, in the-modi.- fied form. of Fig. V, detached from "the wheel. I p

The appliance in which the invention rcsides is made .up of two essential parts, which I shall speak of as anchor member and foot member.

The anchor member is indicated in thethe nhmeral 1. It is a casting drawings by consisting of a block-like body 1, shaped to engage the inner surface of the telly of the wheel and preferably to fill substantially to larger scale, in vertical section on the medial plane of through the wheel and the affords means by which the all of the space between two adjacent spokes. From it extends on one side (it will in service be the side toward the body of the machine) a flange 2, overlying the This anchor block is recessed, so that when applied an eye a is formed. between it and the felly of the wheel. This eye extends transversely and opens across the folly from side to side of the wheel. The anchor block is bolted to the folly of the wheel as is best shown in Fig. II. It will be remarked that as shown in the drawings the bolts by which the anchor block is secured to the-felly extend in a direction radial of the wheel. By this arrangement the strains of service are most effectively resisted. The inner surface of the telly, at the point where it is applied, will ordinarily be faced with a metal bearing plate 3, and the body of the block over those surfaces, which (when the block is placed) extend opposite felly and spoke, will advantageously be faced with a layer 4 of leather or other suitable elastic mate rial. Such a filling of elastic material will be elicctive to hold the block more securel for it will be perceived (Fig. II) that the space in which this block rests, being defined by the telly and two adjacent spokes, is rounded outwardly, and laterally tapers inward. This anchor block, once applied, is

intended to remain in place while the automobile continues in'service. It is no impediment atjall to normal service, and it foot may be quickly applied and secured, and from which the foot, in turn, with like facility be removed. v

The foot member is conveniently made (this oi course is not a limiting point of description) of a forged iron bar, ordinarily :1 rolled iron bar, conveniently of square cross section shown. Thisbar is shaped, as is best shown in Fig.

and terminal extensions 6. The medial loop is of such shape and size as to be capable of being thrust through the eye a, fUl'IIlQd by and between the anchor block 1 and the folly of the wheel. The foot' member is otherwise essentially C-shapcd, and surrounds the tire on. three sidcs-abovc and below, and laterally on the side'next the car body; it stands free of the tire; and its two terminal extensions 6 overhang the tread of the tire at an interval from the face of the tread. shape and arrangement of this foot memspokes.

IV, into a medial loop In all these particulars the sinking in soft ground.

her will readily be understood by comparing Fig. IV with the other figures, particularly Figs. II and III. The intermediate pore tions of the foot member extend opposite the inner side of the wheel, that is theside toward the body of the vehicle, (the righthand side, as shown in Figure III). The foot member may be provided with a stop conveniently in the form of a pin 7, which in the application of the foot member shall abut against the anchor block 1, to certainly define the proper position of the foot member. The terminal extensions 6 of the foot member may be bridged across by a web 8, the purpose of. which is to afford an extended bearing'surface for wet round.

From the web 8 extend groundgripping teeth 9; and these are so disposed that, when the foot member is in service position they extend substantially in the media]. plane of the wheel. Conveniently the web 8 is formed of rolled steel, and the teeth 9 are formed from the plate by slitting and pressing, drawings.

The modification shown in Figs. V and VI is characterized by these features; The square-sectional rod of which the foot memher is advantageously formed is twisted intermediate the extent of the foot member, and the terminal extensions 6 accordingly present sharp edges to the roadbed; the web 8 ceases to be the primary road engaging member (such office being left to the eX- tensions 6 and serves chiefly to prevent ViTith particular regard to Fig. V, it will be seen that in this form there is a lineof bearing, extending transversely of .the tire of greater length than the diameter of the tire itself.

As has been said, while the'ca-r is running in ordinary use, the anchor block 1 will be in place, but the foot member will be stored away in the tool kit, or elsewhere. When, for example, a blow-out has occurred, and a tire is to be removed, the foot member Will be applied to the anchor member while the anchor member is at some point in its circle of rotation other than the lowermost. VVhen applied the foot member will take the relative position fully illustrated in Figs. II, III, and V. \Vhen the foot member has been so applied, progress of the car in either direction until the appliance comes to the lowermost point in the circle of turning of the wheel will effect the lifting of the car; so that it will rest, not on the tread of the tire, but on the foot member, in the position shown in Figs. I, II, III and V. In this position the tire may be removed and replaced. When" all is ready, the further moving of. the machine S 111 either direction will shift the machine again to rest upon the. tire, while the lifting attachment is carried away from the ground.

as is sufficiently indicated in the IV hen this has happened, the foot member may be removed and put away again! It will be observed that, when the lifting attachment is in service and the automobile is supported on the foot member, the tire s freely accessible from. the outside, that is to say, the left hand side as seen in Fig. III.

I do not intend to give an exhaustive catalogue of incidental advantages, but two or three may be noted. This foot member is adapted to serve, not in place of a lifting jack only, but, when occasion arises, will perform the ofiica ot' the attachment now familiar by the name ,mud hook, to carry the machine out of a mud hole in which the wheel otherwise is slipping. The medial loop 5 of the foot member, projecting through the eye -a, forms a ring through which the loop of a padlock b may be introduced. locked to the wheel, the automobile is reasonably protected against theft. Figs. I, III, and V show the padlock in place While the foot member is in its car-sustaining position. It will be understood that ordinarily when the lock is in place the foot member is not in this position, but the appliance stands at some other point in the circle'of the turning of the wheel. This slightly exceptional showing is resorted to, to save repetition in drawing. The actual state of the case will readily be understood. It will thus be seen that the appliance 21-: at once a lifting member, mud hook and. a theftpreventing appliance.

I claim as my invention:

1. An attachment for a vehicle wheel consistingof an anchor block permanently bolted to the telly of the wheel in: a direction radial of the wheel and provided with When the foot member is so" aseat, and a foot member adapted to be 1 thrust into and removed from the seat in presenting to the road a bearing part overlying and spaced from the tread of the tire, substantially as described.
