BRACKET FOR AUTOMOBILE-BUFFERS.

Specification of Letters Patent.

Patented Feb. 22, 1916.

To all whom t may concern.'

Be it known that I, NATHAN W. CRAN- DALL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Brackets for Automobile-Buffers, of which the following is a full and clear specification.

My invention relates to that class of brackets which are provided with means for adjusting and clamping the several members of the device in any desired and predetermined positions, within certain fixed limits.

The object of my invention is to produce a bracket which will be neat in appearance, easily adjusted, elicient in operation, cheap to manufacture and that can be attached to the frame of an automobile in a simple and convenient manner.

The principal object of my invention in relation to the foregoing, is the production of a device which can be fitted to the different shapes of frames existing in different makes of machines, and so adjusted that the adjustable member can be brought up square to the front and firmly clamped and retained in any desired position.

I will now describe the device in its preferred form.

Figure 1 is a side elevation of the complete device, the manner of adjusting it to dierent angles being illustrated in dotted lines. Fig. 2, is a plan view of the device looking downward upon the top, a portion being roken away so as to show the sleeve which encircles the clamping bolt, for the purpose of preventing the collapse of the device when subjected to the pressure exerted by the clamping bolt,`when operating to clamp the shank member and the adjustable member securely together in the proper po- Sition, and shows the perforations in the different members, which are utilized for pivot holes and adjusting slots, &c. Fig. 3, is a view in perspective of the complete device, a spring and a buffer bar being shown in position, the buffer bar being shown in section.

Similar characters denote like parts throughout the several views.

1, is the shank member which is an inverted U-shape in cross section, and is provided at itsv outer end with twoforwardly and downwardlyprojecting ears, extending.

in vertical planes and parallel to each other, as shown at 2. The shank member 1, is preferably formed of sheet metal, but may be made of cast metal if found desirable. The ears 2, are identical in every respect, each being a counterpart of the other, and as but one sideis shown in elevation in either of the figures in the drawings, their positions are well defined in the section illustrated in Fig. 2, and I will hereafter refer to them and their construction in the singular, in order to avoid confusion in the description. The ear 2, is provided with a perforation 3, and a diagonal slot 4, for a purpose which will be fully hereinafter explained. The slot 4, is projected obliquely to an imaginary line projecting radially forward from the center of the perforation 3, and at an acute angle thereto. Grooves 5, and 6, are formed in the top of the shank member 1, for the reception of the staples 7 and 8, which in conjunction with the clip-yokes 9, and 10, lockwashers 11, and 12, and nuts 13, and 14, serve to securely fasten the device to the frameof that class of automobiles, which are provided with forwardly projecting frame portions, as at 15, and to which is secured the spring 16.

As the frame and spring just referred to forms no part of this present invention, but are simply shown to better illustrate the manner of securing the bracket in position, no further mention of them will be made, other than to later 0n explain the operation of the device.

An adjustable member 17, having upturned sides 18, extending at approximately right angles to the face thereof, (and again I will refer to this member in the singular since both sides of the said member are identical in every respect,) is provided with a perforation 19,'and diagonal slot 20, said slot extending at an acute angle to an imaginary line radiating from the center of the perforation 19, and at an angle approximating 45 degrees to the front face of the member 17. ,A rivet 19', is passed through the. perforations 3, and 19, and headed over at each end so as to form a'neat and secure pivot joint, upon which the adjustable clamping member 17, is swung when adjusting the same to any desired position. A sleeve 21, is interposed between the ears 2, of the shank member 1, and is designed to sustain the ears 2, in their proper position when subjected to the clamping action of the bolt 22, and its nut 24:, said bolt being passed entirely through both sides of the said adjustable member 17, and both ears 2, of the shank member 1, at the point of intersection of the slots 3 and 20, and also through the sleeve 21, and lock washer 23, and by reason of its clamping action, when the nut 24, is screwed home, binds all of the several parts firmly together in any desired position. Binding clips 25, and 26, are formed by severing the metal of the adjustable member 17, as shown in Fi 1. Bolts 27, and 28, are passed throug perforations, (not .herein shown,) in the binding clips 25, and 26, lock washers 29, and 30, and nuts 31, and 32, are screw threaded upon the free outer ends thereof. A spring 33, of the inverted U-shape type, has one of its ends passed down through the bight of the adjustable member 17, and in front of the bolts 27, and 28, when as will be readily understood by screwing the nuts 31, and 32,

home against their seats, the binding clips 25, and 26, are forced inwardly against the edges of the spring 33,' holding it firmly and securely in its proper place. The buffer bar 34, is next securely fastened in position upon the forward ends of the spring 33, when the operation of mounting the device is complete so far as a single bracket ison cerned, as two brackets are employed in mounting a buffer bar, the operation is repeated upon the other side of the frame of the automobile, and the opposite end of the buffer bar.

Having thus described my invention what I claim and desire to secure by Letters Patent is An adjustable bracket for automobile buffers comprising a 4shank member and a clamping member pivotally connected together, a portion of said shank member extending within the side Walls of said clamping member, oblique slots in the side walls of said shank member, and oblique slots in the side walls of said clamping member arranged to extend diagonally across the said oblique slots in said shank member, when said members are located in proper relation to each other, a bolt 'extending through all of the slots in said members, and slidable therein when said clamping member is rotated about its pivotal center, a nut upon the free end of said bolt for clamping said members together in predetermined positions, andI a sleeve upon. said bolt and between the side walls of saidy shank member to prevent the collapse of the said members when subjected to the clamping action of Said bolt, all arranged and operating substantially as shown and for the purJ pose set forth.

In testimony whereof I, aiiiX my signature in the presence of two witnesses. j
