To-aZZ whom t |may concern:

Be it known that I, HERBERT V. SoUDERs, a citizen of the United States, residing at. Wilmington, in the county of 5 and State of California, have invented new and useful Improvements in Jack Bolsters, of which the following is a specification.

My invention relates to vehicle jacks, and a purpose of my invention is the provision 1 of a bolster-adapted to be associated with a jack of conventional form to occupy, when the jack is in active position, an interposing position between one of the springs of a vehicle and the head of a jack thus permitting of the direct application of the jack to a vehicle spring in effecting a lifting of a vehicle wheel and thereby eliminating the necessity 4of an operator crawling beneath a' vehicle to apply the j ackas is now the custom.

It is also a purpose of my invention to provide a jack bolster which is pivotally associated with the spindle of a jackso as to be extended when in active position, and compactly folded with respect to the jack when in inactive position, the jack bolster thus constituting an integral part of a jack. Although I will describe only two forms of j ack holsters embodying my invention and point out the novel features thereof `in claims, it is to be understood that various changes and modifications may be made herein without departing from the spirit and scope vof such claims. In the Iaccompanying drawings,

Figure 1 is a view showing a portion of a mot-or vehicle having applied to thespring thereof a jack and one form of jack bolster embodying my invention.

Fig. 2 is an enlarged fragmentary view showing in side elevation the vehicle spring, bolster and jack spindle.-

Fig. 3 is a top plan view of the bolster shown in the preceding views.

Figs. 4 and 5 are transverse sectional views taken on the lines 4-4 and 5'5, respectively, of Fig. 3.

Fig.

6 is a fragmentary view Showing in side elevation the jack bolster hingedly associated with a jack spindle and also embodying my invention.

Similar reference characters refer to similar parts in each of-the several views.

Referring specifically to the drawings, my invention, in 4its present embodiment, com- Los Angeles prises a channel bar B formed `of a single length of metal and including a linear portion b and a curved portion bl The linear portion b is shown as tapered in width from its point of connection with the curved portion b', and its free end provided with a head 16 arranged transversely of the p0rtiony and including an upwardly extendin flange '17 at the ends -of which are forme upstanding projections 18. As clearly shown in Fig. 5, the web of the portion b is disposed lowermost with respect to the bar so that the edge flanges extend upwardly.

The portion b is curved upwardly from its point of connection with the portion b, and as clearly shown in Fig. 1, the web 19 thereof is disposed reverselywith respect to the web of the portion b so as to providea recess 20 upon the under side. of the portion which is adapted to receive the head 21 of any conventional form of jack. As the greatest preure is exerted upon this curved portion b', it is preferably reinforced by means of intersecting ribs 22 as clearly shown in Fig. 3, these ribs being formed integral with the web 19 as will be understood. The free end of the portion b is provided yvith an upstanding flange 23, and the opposite ends of this flange are formed with upstanding projections 24.

In the applied position'of the bolster as shown in Figs. 1 and 2, the projections 18l and 24 serve to maintain the bolster against lateral displacement with respect to the spring designated at S of the vehicle, and as particularly shown in Fig'. 2, the bolster contacts with the spring only at

flanges

17 and 23.

In practice, any conventional form of jack such as the jack J shown in Fig. 1 is associated with the bolster so that its head 21 is disposed within the recess 22, and with the bolster applied to the spring as shown, it will be clear that by actuating the jack the spindle 25 thereof when moved upwardly will co- 100 operate with the bolster and spring in effecting anelevation of the vehicle wheel.

It is to be particularly noted that the' deposition of the recess 22 is such that thejack J- can be applied to the bolster at a 105 point in the rear of the vehicle wheel, thereby permitting of the actuation of the 'ack from a point 1n the rear or at the side o the vehicle, thus eliminating the necessi of theoperator crawlingv beneath the ve 'cle to 110 j operation.

apply the jack as is the present practice. The length of the bolster B is such as to properly distribute the pressure exerted by the jack along the length of the spring thereby preventing distortion of the spring and a separation of its leaves during the lifting In the form of bolster just described, it is adapted to be applied to and removed from the spring independently of the jack, as it is my intention that this bolster be adapted for use with any jack of conventional form.

However, in order that the bolster may constitute an actualpart of any conventional form of jack so as to prevent loss thereof and to facilitate the application and removal thereof to the spring, the bolster is hingedly connected to the spindle of a jack in the manner shown in Fig. 6. As here shown, the upper end of the spindle 25 is provided With an ear 26 instead of the head 21, and this ear is adapted to be inserted between a pair of spaced ears 27 formed on the bar B through Which a pivot pin 28 is eX- tended.

By this construction it will lbe clear that the bolster can occupy an extended position in which it is disposed substantially at right angles to the spindle for application to the spring, ora folded position in which it is disposed substantially parallel to the body of the jack so that it may be easily stored Within the compartments provided tor this purpose in a vehicle.

What I claim is:

1. lln combination, a vehicle including a spring, a jack adapted for arrangement beneath the spring and in the rear or advance of the adjacent Wheel, and a bolster interposed between the head of said jack and spring and formed with a jack head receiving portion adjacent to the outer end thereof whereby the operating lever of the jack is so disposed as to permit actuating thereof Without reaching beneath the vehicle.

2. A bolster of the character described v the mamies comprising a channel bar including a linear portion and a curved portion, the Webs of said portions being reversely disposed to provide a recess at the inner side ot the bar and at a point intermediate of its ends.

3. A bolster of the character described comprising a channel bar including a linear portion and a curved portion, the Webs of said portions being reversely disposed to provide a recess at the under side of the bar which is accessible from one end of the bar, transverse and upstanding flanges formed on the ends of the bar, and upstanding projections formed on the ends of the flanges.

4. In combination, a jack includinga spindle and a bolster adapted for use in connection With a jack and movably secured to the spindle to occupy an extended position in which it is disposed substantially at right angles to the spindle, and a folded position in'which it is disposed substantially in parallelism to the spindle.

5. A bolster adapted tor use in connection with a jack and comprising a bar U-shaped in cross section for a portion of its length and of inverted lJ-shape in cross sections for remainder of its length.

6. A bolster comprising a channel bar having upturned ends and the web thereof reversely disposed from a point between its' ends to provide on the under side of the bar a recessportion adapted to receive the head of a jack. 1

7. A bolster comprising a bar Ushaped in cross section for a portion of its length and of inverted U-shape in cross sections for the remainder of its length, the first portion being of linear form and the remaining portion curved.

8. A bolster comprising a. bar having a recess in its under side which is accessible from one end of the bar to permit the application of a jack thereto.

ln testimony whereof I name to this speciiication.
