Patented luly'ls, 1930 mam CARL BLPARS ONS, O'ZE DETROIT, MICHIGAN LOADING BLOCK Application filed. February .24, 1928 Serial No. 256,519. I

My invention relates to an improved vehicle wheel chock adapted primarily for use as a loading block in the shipment of motor vehicles. i

5 An object is to provide an improved vehicle wheel chock formed of sheet metal which is of a'strong sturdyvconstruction and is light in weight and inexpensive asto cost. 1 If desired, it may be retained for reuse but ameri- 1o torious characteristic is that; it is so cheap in price that it may be thrown away after use.

An advantageous feature lies in the provision of a vehicle chock which is formed from a single sheet of light weight sheet metal 15 by a relatively simple stamping operation and yet which possesses sufficient strength to effectively serve its purposein the use for which it is intended. Y

Other advantages and desirable features 20 of my invention will more fully appear from taken on the line block of modified single piece of light weight sheet metal longi tudinally corrugated as appears at 10 to lend strength and rigidity thereto. The metal sheet is so formed as to provide an arcuateportion 12 shaped to embrace the periphery of the road wheelofthe vehicle and each endis bent downwardly as at 14: forming supporting legs; The supporting legs are not only bent wardly as "appears in Fig. 2 so that the oposed upright edges of each leg aresubstantially parallel and are substantially perpene.

7 dicular to the meeting edge of the arcuate portion and to the axis of such arcuate portion so that the load strain is borne directly along a line extending longitudinally and substan tially midway the edges of the'legs. Each leg is downwardly asappears in the 'figuresof the drawing but'they are bent obliquelyfreare bent outwardly at its lower end forming a foot 16 which may be perforated as appears at 18 to receive suitable nails or other fastening means to secure the block to the floor of the car upon which the vehicles are being transported. Each edge of the legs and the arcuate portion is shown as rolled over as at 20 and I provide a reinforcing brace member 22. This brace member. has the shape generally of an inverted V and the arms 24 thereof meet at a common point along r the edge of the arcuate portion 12 and extend downwardly diagonally to engage the adjacent side of the leg at a 'point in proximity to its foot. The above structure'is that shown in theiirst three figures of the drawing;

InFig. 4 I have shown a simple structure formed entirely of a single piece of'metal and wherein the upperend ofv each leg portion 14 is bent underneath the adjacent side portion of the'arcuate part 12 so'as to. form a marginal fold 26. The legportion then is bent downwardly from a point 28'underneath and spaced from the edge of the arcuate portion flaring outwardly as shown in the figure of the drawing and extending rearwardly as is shown in Fig. 2 of the drawing.

The leg portions are here provided with' feet 16 as has been heretofore described. The

entire structureis preferably corrugated as has been heretofore described and the load strain rests more directly upon the legsand the transverse reinforcing power 'may, as shown, beeliminated; An additional meritorious feature is that with my improved loading block relatively small and lightcnail's may be used to secure the blocks to the-floor of thecar which will not materially damage the floor. 17

'- WhatI'claimis: V i

' 1.A loacling block 7 light sheet metal and comprising an arcuate "wheel engaging portion having a pair. of leg portions bent downwardly on oppositesides "thereof. and extending rearwardly obliquely therefrom, and an inverted generally V-' shaped'brace member extending from oneend of the a'rcuate portion to each leg adjacent its foot.

2. A loading-block formed of 'a strip of longitudinally corrugated light'sheet metal 1 formed of relatively bent transversely to form an arouate portion shaped to embrace the periphery of the Wheel and having on each side a downwardly bent leg portion extending obliquely rearwardly from the arcuate portion so that the corrugations of the leg portions are substantially perpendicular to the axis of the areuate portion, and a brace extending from each leg portion diagonally to the adjacent end of the arouate portion.

In testimony whereof, I, CARL B. PARsoNs, sign this specification.

ChRL B. PARSONS.
