A further object of the invention, is to construct a chock block from lumber of standard sizes as before mentioned with the 2 lumber cut or split at certain angles and as- V 2 0 rial.

sembled in a manner to provide a dished or substantially concave tread surface and possessing the strength of the usual solid chock block constructed of a single piece of mate- With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying draw ings and claimeda In the accompanyingdrawings Figure 1 is a side elevationalview of a 21,3 chock block constructed in accordance with the present invention, V

Figure 11 is a detailed sectional-view of the tread portion of a chock block showing the tread surface of the spacer bar transversely grooved, and 1 Figure 12 is a side ,elevational view of the chock block wherein an angle corner edge of the brace heel constitutes the support. p

In the form of the invention as shown in Figures l to 6,-there isillustrated a chock block comprising side walls, an intermediate spacer bar and a brace heel, all of. the parts being nailed or otherwise secured together. As shown in Figure 5, a2 x ltimberis diagonally out between the sidewalls thereof and lengthwise upon the line 15 to provide side wall sections 16 and the 2x4 timber illustrated in Figure 6 is transversely out between the side walls lengthwise thereof upon the line 17 to provide spacer bars18. I

The side walls 16 of the chock block are placed as illustrated in Figures 1 to 4 with the angle cut faces15 opposing each other and separated by theintermediate spacer bar 18, this arrangement p-roviding'asubstantial cavity in the faceof the chock block for the support ofa vehicle wheelf The spacer bar 18 projects rearwardly of the side walls 16 as at 18* to addadditional strength to the block, the upper end. of the spacer bar 18 terminating at a point spaced from the upper ends of the side bars, while the" lower end of the spacer bar and side bars terminate in the same place and are angularly cut as at 19 V to provide an inclinedbearing end for the chock block as illustrated in Figure 1. The side walls 16 and spacer bar 'l 8 are secured together by nails 20 or other fastening devices as illustrated in Figures 1 to 3. a The brace heel comprises a piece "of 2 X timber 21' to provide a substantially inverted of therbrace heel being cut away as at '22 to provide a center block projection 24: re-

ceived between the upper ends of the side bars 16 to rest upon the upper end of the spacer bar 18 as shown in Figure 2, a nail or other fastening device being provided for securing block projection 24; to the upper end of the spacer bar 18. The lower end of the brace heel 21-isangularly cut as at 26 for flat surface contact with a floor or other support.

It will therefore be observed that a-chock' sidebars, a central spacer bar and an inblock of substantial construction embodying an abundance of strength, may be constructed from practically wastelumber and a material saving eifected, the block in all appearances being substantially the same as the usual one piece 'block'with a facial cavity for the support of the vehicle wheel and side walls to preventlateral displacement.

, In the form of the invention illustrated in Figures 7-and 8, the side walls 16' are angularly cut from a 2 X itimber and'the spacer bar 18 is an uncut 2x 4 timber that projects considerable distance rearwardly of the side walls 16*: to provide an additional nailing support for the rear brace heel 21 as illustrated in Figure 7.

The chock block shown in Figures9 and '10 with side Wang 16 is cut from a 2X6 timber which provides side walls of greater depth and the spacer bar 18 is an uncut 2 x 4 timber interposed between the side walls, but

does not project rearwardly thereof as illus-' trated in Figure 10; The heel brace 21 is formed of a 2x6 timber and has a con- 1 nection between the upper ends of the ' l'ieel V braces 21 and 21" shown in Figures 7 to10 is the same as illustrated in connection with Figures 1 t0 6.

In the form of the invention illustrated in Figure 11 side bars 16 are separated by aspacer bar 18 that has its face transversely concaved as at 18 to provide the usual continuous transverse curve found in thetread surfaces of chock blocks.

' In'each form of the invention previously discussed, the lowerend ofthe braceheel 21 is cut at an angle to provide aflatbearing surface, but if desired, and as illustrated in Figure 12,'the lower end of the brace heel 21 may have the usual straight angle end 21 with a corner edge of the heel providing a support for the heel brace. 1

While there is herein shown and described the preferred embodiment of the invention, it

is neverthelesstov be understood that minor changes may be made therein without departing' from the spirit and scope of the invention as claimed.

What I claim as new is: f o

' 1. Inachock block, a'tread wall including side bars, a central spacer bar and an inclined heel brace. 1

2. In a chock block, a tread wall'inclu'ding side bars, a central spacer bar andan inclined heel brace, and the opposed faces of the side bars outwardly of the spacer bar flaring outwardly.

8. In a chock block, a tread wall including sidebars, ajcentral spacer bar and an inclined heel brace, the spacer bar terminating at its upper end below the upper ends of'the side bars and ablock projection] on the heel brace extending between the upper ends of the sidebars". i 7

4:. In a chock block, a tread wall including clined heel brace, andthe opposed faces of the sidebars outwardly of the spacerbarflaring outwardly, the-spacer bar terminating at its upper end below the upper ends of the side bars and a block projection on the heel brace extending between the upper ends of side bars and ablock projection on the heel brace extending between the upper ends 'of the side bars, and means for fastening the side barsto the spacer bar and the block pro jection to the spacer bar.

6. Ina chock block, a tread wall including j side bars, a central spacer bar and an inclinedv heel brace, and the opposed faces of the side bars outwardly of the spacer bar flaring outwardly, the spacer bar terminating at its upper end below the upper ends of the side bars and a block projection on the heel "brace extending between the upper ends of the side bars, and means for fastening the side bars to the spacer bar and the block projection to the spacer bar.

11. The method of constructing a chock block consisting of longitudinally splitting at a transverse angle, a timber that is rectangular in cross section, rearranging the two pieces of split timber to present the angle faces in opposed outwardly flaring relation, positioning and securing a spacer bar between the two pieces of split timber and angularly attaching a heel brace to the side bars and spacer bar.

In testimony whereof I aflix my signature.
