AUTOMOBILE JACK.

Original application lecl February 6, 1925, Serial No. 7,367.

Divided and this application led August S, 1925. Serial No. 49,151. i

This invention relates to automobile jacks shown and described in'my co-pending application Serial #7367, filed February 6, 1925, of which this application is a division.

An objectof the presentinvention is to provide a device which is capable of quick and easy attachment to a vehicle wheel, and which when so attached will cause the wheel to be elevated from the ground upon rotation of the wheel.

A further object of the invention is the provision of a device in which a removably mounted U-shaped anchor plate is adapted to be readily connected to the felly of a wheel by means of the usual bolt that ordinarily secures the demountable rim by means of a lug especially constructed for that purose.

p This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specilication; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a side view of the wheel showing a jack constructed according to the principles of my invention, Vapplied. thereto,

Figure 2 is a vertical section of the jack taken along the line 2-2 of Figure 1, and

Figure 3 is an enlarged fragmentary perspective view of an anchor employed inv Figures 1 and 2.

Referring more particularly to the drawings, an anchor plate in the shape of an inverted U-shaped member is adapted to be applied to the wheel having a wooden felly, and in which case the bolt 9 serves to hold the anchor in operative position on the felly 11, in addition to supporting one of the lugs 12 which ordinarily secured the demountable rim 13 and the tire 14 in position. The anchor 10 is a substantially rectangular metallic block which is recessed or cut out centrally of its under surface as at 15 to fit over the felly 11 with the depending walls 17 and 18 engaging the respective sides of the felly. The walls 17 and 18 are provided with alined apertures 19 to receive the bolt 9 and the wall 18 is recessed on its outer surface as at 20, to receive the lug 21 which is also transversed by the bolt, the free ends of the walls, the-bottom of the cut out portion, and the shoulder 21, all being suitably curved to conform to the curvature of the felly 11. The lower free edges'23 of the walls 17 and 18 are curved to conform to the curvature of the rim 13 and is adapted to engage said rim in order to prevent locking of the anchor plate when secured in place. A transverse opening 22, rectangular in cross section is provided in the anchor plate 10 to receive a rectangular extension 7 of the ack which is provided with a pair of legs spaced from each other and in V- shaped formation, so that the lower ends or feet 24 of the jack will properly engage the ground when it is adapted to raise the wheel by the jack.

In practice of the invention, each wheel of the vehicle is provided with a second su pporting anchor 10 which is secured to the felly by means of the bolt 9. In case of a puncture or any other trouble necessitating the removal of the tire, the driver has only to insert the shank extension 7 of the jack into the housing with the ydiverging arms 8 extending or raised from the ground. The brake of the vehicle being released, the tire may be moved a slight distance in either direction to cause the wheel to rotate by a forward movement of the vehicle whereupon the rearward foot 24E will be the first to engage the ground and the wheel will be gradually elevated as by a fulcrum, until the other foot of the forward leg will engage the ground and thereby support the wheel as shown in Figure l, in an elevated position.

llhen it is desired to lower the wheel after the repairs have been made to the tire, the vehicle is either moved forwardly or rearwardly when the legs of the jack will be raised from the ground and the vehicle will then again be supported by the tire 14. lt will be seen by such a construction that it is only necessary to insert the jack in position within the anchor `1O and drive the wheel forwardly a slight distance to cause the legs to engage the ground and elevate the vehicle at this point, as shown.

' l claim:-

1. The combination with an automobile wheel of a housing including a rectangular metallic block longitudinally grooved centrally of its lower side for receiving the rim of the wheel, transversely apertured for receiving a bolt for securing the housing on the rim and recessed on its outer fece for reception of a rim holding lug, and a jack including a pair of diverging arms and an integral angularly extending projection, said housing being transversely slotted for receiving said projection to support the jack in operative position on the Wheel.

2. A device of lche cla-ss described adapted for use in connection with a, Wheel having a demountable rim and comprising in combination e jack having road-engaging arms and e lateral projection, a U-shaped housing adapted to engage over and completely embrace the inner periphery and sides of the elly of the Wheel, means for securing the U-shaped housing to the felly, said U-shaped housing being provided with zr transverse sloty adapted to receive the projection on the jack, the side edge of the U-shaped housing being cui'l away to provide e seat to receive a securing lug and ay shoulder to neatly cngege an edge of the lug, the shoulder cooperating with the lug to :iid in preventing displacement of the U-shaped housing.
