' To aZZfu/'w-mit may] concern.'

Be it known that l, linnn ABN, a citizen of the United States, and resident of Chat tanooga, Tennessee, have invented certain new and useful. improvements in Chech- Blocks for Automobiles, of which vthe ich 'lowing is a specification.

My invention is designed to provide a chock hloelr which may he manufactured economically hoth as to the material used sind the time expended in severing the blocks om a piece of timber and in their formaon to the desired shape. ln the eccompanying drawings* Figure l is a side vienr oi a chock block embodying my invention and Q is a perspective vier/v.

The block is 'formed of a single piece of `wood having a trent tace which conforms in curve to the general peripheral curve oi the Wheel andhaving in this curve tace a groove conforrning to the substantially cylindrical` shape of the tire. The block has parallel side faces and it has an extended heel portion et 2. This is formed by cutting the i rear fece on an incline and in one plane from the 'top to the bottom of the block and the plane upon which this incline is formed is the diagonal of an oblong` oi' which the height corresponds to the height of the block and the width corresponds to the distance loetween the upper rear edge ot the block and e. vertical plane extending unirono the rear lower edge ot the extended heel. This incline is such that 'when the piece 'from which the block is formed is severed on this incline from the piece ot timber, the incline face.

left Aet the end of the piece of timher will provide the extended heel portion ot the next block. ln other words, the seme ent which severs the block from the piece of tim'her provides the tivo incline Jfaces which form the extended heels et the two blocks succesv sivelv cut from the timber. This extended heel presents the advantage that a surface is provided which will readily receive the nails tor attaching: the hlo'ck to the platform or the car or the storage house in which the automobiles are carried or stored, it loei'ngg1 possible to ins'ert the nails with greater ense and facility in this inclined rear face rather than in Ve vertical rear tace. Furthermore, this rearwardly inclined heel extension provides'a hearing on the tloorat a considerable distance beyond the hearing 'hice ofthe block so that there will he no danger of the block tipping over if an automobile, is brought against it with considerable force, and thus the nails will not he strained and will not he drawn from the platform and the block straight eut which severe the lolock from the timber alsohas tlie etliect of forming the rear face of the severed block and also the rear face of the nent block to he out vtrom the timber.

Referring to the adoptahilty' of the inclined rear fece for receiving; the nails, it may he further pointed out that the nearer the nails are positioned perpendicnlarly to the door of the car or otherv erinnert to which the blocks are to he afiixed, thd het/ ter will the nails hold against the strain to which the blocks are subjected. ii, plieants inclined rear tace enables the neil to be set substantially perpendicular to the car floorl or receiving surface, 1and et the same, time' the head ot the nail is freely accessible for the hammer hloivs to he applied thereto, .he-

cause, it will loe noticed, that the rear inclined 'face slopes upwardly and away from the vertical plane in which the nail is positioned. This is not true, however, in e construction having a vertical rez-ir fece', because the nail would in Athe latter case have. to loe Y placed at a considerehle inclination to the rear tace and to the door ot the cer in orderto enable it to be driven into pince.

claim as my invention: 1 A chock block for automobiles formed of a solid piece ot wood having a hase portion,

a curved front hearing face extending from the top of the block to the .bottom support'- ing face oit-the base portion and e reerf' ioo l wardly extended heel incliningg, in one piene downwardly and hackwardly troni the upper to the lower tace of the block, suhstan tielly as described.

In testimony whereof., i
