CHOCK BLOCK.

Application filed December 10, 1923. Serial No. 679,894.

1 This invention relates to certain new and useful improvements in chock blocks and particularly to the type such as are used fnr securing vehicles, such as automobiles, in

5 fixed positions in cars during shipment thereof. V The invention embodies certain improvements in the art to which it relates, bearing particular reference to the patent to Edward W S. Evans, No. 1,188,745, dated June 27, 1916 and the reissue patent to Edward S. Evans,

No. 14,306, dated May 29, 1917, the primary objectof this invention being to provide a chock block of the general type disclosed in V the above mentioned patents wherein the heel portion of the block is so constructed as to permit the wedging positioning of a crowbar between the outer end of the heel and the car floor or support for prying loose or removing the chock block from its an chored position. 7

Another object of the invention is to provide a chock block of the type above set forth with protecting face plates upon the upper and lower sides of the block heel to prevent damaging the heel and destroying the block during positioning of the block as by the driving of nails or spikes through the heel, and the removal thereof when a crowbar or like implement is employed for such purose. p lVith the above and other objects in view as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a perspective view of chock block showing the face plate secured to the upper side of the block heel,

Figure 2 is a perspective view of the chock block, taken at a different angle, and

showing the face plate secured to the lower face of the heel with the upwardly curved outer end of the lower side of the heel and lower face plate,

Figure 3 is a vertical longitudinal sectional view of the chock block showing the same anchored upon a car floor or other support with an automobile wheel illustrated by dotted lines engaging the block, and further showing the upwardly curved portion of the outer end of the lower face of the heel with a crowbar illustrated by dotted lines in position for prying the chock block away from the support,

Figure 4 is a rear elevational view of the chock block with the heel shown in section, and

Figure 5 is a vertical sectional view of the heel portion of the block with a modified form of face plate therefor.

A. chock block in accordance with my invention is preferably formed of wood. In manufacture, I am enabled to take short ends or lengths of logs or timbers of relatively sound nature, but which, owing to their lengths may not be worked into other mercharitable lumber. The timbers are sawed into lengths of generally rectangular form in cross-section from which two blocks may be produced.

The block designed generally as A, is

preferably formed of a length somewhatexceeding its height at the highest point, and of a width or thickness which will give the block a secure purchase upon the floor or other base, and also permit of the grooving of the one face of the block without a weakening of the same.

The wheel-engaging face of the chock block is preferably cut on an arc to conform to the curve or arc of a tire, and this curved or arc-face in the embodiment here shown, is provided throughout its length with a groove B that is adapted to neatly receive the tire C of the wheel as shown in Figure 3. It is preferable through not essential to the operation that the small or forward end of the chock block be cut off blunt as shown at D. This is preferable for the reason that it does not in any way interfere with the proper operation of the block, and it prevents danger of the block splitting, due to the rough handling it receives in shipment before being used; also it obviates any danger of splinters or fins on the feather end of the block, which might injure the rubber tire of the wheel to which the block is applied. As stated, the embodiment herein shown has the wheel-engaging face cut on an arc and also grooved to receive the tire. This however, is but illustrative. the invention involved being the provision of a heel or ledge at the rear of the block for a purpose as will now be described. On the rear face E of the chock block, the same is cut away to produce a ledge or heel G, on the rear face of the block adja- CJI cent the base thereof. This cut away portion mi v be formed as shown at F in Figures l, 2 and 3, but the form thereof is immaterial, so long as the completed block contains the clearance to produce the heel or ledge G.

The heel G is of well defined proportions as illustrated, the upper face of the heel being out upon a straight line or on a line parallel with the lioor or support H. As clearly shown in Figs. 1 to 5, the lower face of the heel G adjacent the outer end thereof is curved upwardly as indicated by the reference numeral 1 to provide a wedging or substantially V-shapcd space between the lower face of the outer end of the heel and the floor support H.

The block A being constructed of wood and with the heel portion G thereof being subjected to unusuady rough usage in anchoring the block to the floor support by the use of nails or the like driven through the heel, metallic protecting plates are secured to the upper and lower faces of the heel, the plate 2 covering the entire upper side or face of the heel and being anchored thereto as at 3 by the employment of rivets or the like, the bottom plate l cm'ering the lower face of the heel and extending a considerable distance over the lower face of the block inwardly of the heel with the outer end thereof arched upwardly at 4; into intimate contact with the lower curved face 1 of the heel, the fastening devices 3 anchoring both plates in position. The chock block A is anchored in position upon the floor support H by means of the nails or spikes 5 passing through registering openings (3 formed in the heel G and the upper and lower face plates 2 and -l as shown in Fig. ln'lieu of the separate plates 2 and 4, a channel plate 9 may be employed to inclose the heel G and extend above and below the same, see Fig. 5.

By the provision of the cut away portion F atthe rear side of the block A and the well defined proportions of the heel G, considerable space is afforded in accommodating the mounting of the block by permitting free use of a striking element, such as a hammer in driving the nails 5 into the floor H through the registering openings 6 in the block heel and face plate, the openings (3 being positioned inwardly of the block heel and further slightly spaced from the upper curved lower face thereof, the inner end of the lower face plate lbeing secured as at 7 to the lower face of the chock block it. .Yith the block positioned as illustrated in Fig. 2- upon the floor support H, a wedging opening or substantially V-shaped space is provided between the floor supp rt and the lower face of the heel G at the outer end thereof to permit the wed ing positioning or insertion of the pointed end of a crowbar 8 or similar implement as illustrated by dotted lines. In removing the block from the floor support, the crow bar 8 is forced into the space between the floor supportand the lower curved face of the block heel, leing wedgingly driven therein and upon downward movement of the outer end of the crowhar the fastening devices, such as the nails 5 are easily removed from the floor support for disn'iounting the chock block. The upper face plate 2 provides protection for the upper face of the heel during the driving of the nails 5 into the floor support while the lower face plate l protects the heel when the block is being removed. The gist of the present invention resides in the provision of a wcdging space or opening between the outer end of the block heel and the floor support to permit the insertion of the pointed end of a crow-b'ar or similar implement for wedging reception in such space, this particular forniatio'n of the lower face of the blot-la heel tending to eliminate slippage of the crowbar from its wedged pcsition and further insuring enhanced facilities bet veeuthe crm'vbar and By the provision of a chock gripping block heel.

tl character, the same may block of no scc rely anchored to the floor support without injuring the heel portion thereof and may also be readily removed therefrom for future use, it being noted that the outer end of the heel is free of any grooves or similar forn "li'iCIlS and entirely relies upon the upwai curved or extending outer end of the lower face of the heelt'o obtain toe ii'edging action for the crowbar, the protecting platesand -l eliminating injury to' the heel (i during the mounting, and removal thereof.

ll' hile there is herein'shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be. madethcrein without departing fronl'the spirit and scope of the invention as claimed.

What is claimed as new is A chock block for automobiles having a horizontal lovv'cr face, a rear face perpendicular thereto. a heel portion projecting rearwardly and forwardly of the plane of the rear face with the lower i'a'ce of the heel curved outwardly and upwardly defining a wedging space between the heel and block support, the heel being adapted for the reception of securing nails, the forwardly projecting portion or the heel being formed by the cutting away of the block inwardly from its rear face, and reinforcing means secured to and tlushly engaging the upper and lower faces of the heel and the lower face of the adjacent portion of the block.

In testimony whereof I atlix my. signature.

EDWARD S. Evans.
