To all whom' mag concern:

Be it known that we, JAMES T RNER and PEARL P.'CRAB1L citizens of the United- States, residing at Springfield,in the county of Clark and Statejof Ohio, have invented certain new and useful Improvements 'in Butlers for Automobiles, of which the following is aspecification.

This invention relates to'improvements in bufiers especially adapted for automobiles.

An object of the invention is to provide a bu'fler which may be quickly and readilyattached to the VehiCleWithO'utthe necessity of alterationsfas the drilling of holes in the frame of the machine or'the removal of any of the parts thereof.

A further object of the invention is to" provide means whereby the bu-fierrnay be adjusted-so as to maintain the buffer springs v and bar in a straight .horizontal. position with respect to themachi'ne to which it is the vehicle.

Th invention consists in the construction ii'i the. claims."

I

b is the buffer bar ofour improved device, which extends transversely across-the front of the vehicle and is.'constructed'inthe usual and ordinary manner. This bar extends through and is secured to collarsb, each of said collars beingprovided with a set-screw elliptic springs pivotally connected at the b for the purpose. Each-of these collars has a rearwardly extending sleeve 6 which is slidingly mounted upon a rod bflwhich pro jects iorwardly fr'om'the' head or frame;

which clamps the device to the vehicle this head or frame consisting essentially of two parts 0 and 0., pivotally connected toether I in the mannerhereinafter more f y de scribed. A coiled spring 6 laced about the sleeve 12 and the boss I) on the-forward part of the head orwardly; a

therefromand into slots b in the j'sa'idsleve' 12 serves-to limit the forward movement of.

portion a, serves jto' normally. proj ect the 00 art and hence the-buffer bar pin 6 extending throug'hihe .rod 32 with its ends projecting laterally the sleeves'iunder the stress of the springs.

.As before stated, the respective portions 0 and .c of the head or frame are pivotally" connected together, the pivot being in the nature of a screw bolt 0 (F i'g, 7) which exthe part c and is screwed into he'respective parts of the head curved s otted opening 0 in the part a and is fscrewedintothe part 0' (Fig; 6 a washer e jfbein interposed'j between .the' ead of the bolt an the side of the part'c, as shown.

- Theres'pectiveparts of the head where'they channel frame a, and is adapted to be fitted thereto." Depending from the rear portion of the art a is'a stationar clam in meme P y P g her 0, which may be formed integrally with said part, c. The depending portion 0 has secured thereto at its lower end a laterally projecting rod 0 which terminates in a re- "duced screwthreaded portion 0 said rod 0 being secured to the depending portion 0 by the nut c screwed onto a reduced portion of the rod 0 which reduced portion projects through a perforation in the part 0. The head part 0 has a screw-threaded opening located on the opposite side of the depending portion 0 adapted to receive a clamping screw, the 'head of which is represented by 0 0 is a movable clamping member which cooperates with the stationary 'clampin member 0? and is perforated at its top an bottom so as to receive the clamping screw,

and 0 may be provided with a' series of perforations as indicated at 0 so as to accommodate the device to different sizes-of channel frames. The rod 0 is also provided with a set screw 0 which is tightened against the bottom of the'channel frame, a, to. assist in holding the device in position. Each of the clamping members are recessed as indicated at 0 in order to accommodate in some cases both heads in the channel frame.

After the device has been firmly clamped to the channel, byloosening the clamping bolt 0, the portion 0 of the head may be ad justed so as to cause the rod 6 thereon-to project in a straight horizontal position and hence maintain the buffer springs and other parts in av horizontal position so that any thrust upon any of the parts may be a direct one.

It will be seen by this construction that the device may be attached to a vehicle with out the necessity of altering or removing any of the parts of the vehicle and that a large part of the shock of "a collision will be brought directly upon the ends of the channelframe, a.

Having thus described our invention, we claim:

1. In a bufi er for vehicles, a buifer bar,

and means on each side of the vehicle for connecting said bar thereto, said means comprising a two-part head adapted to be secured to said vehicle, the respective parts of said head being pivoted together, together with devices for clamping the re spect-ive parts of said head together, substantially as specified.-

2. In a buifer for vehicles, a buffer bar, a two-part head on each side of said vehicle together with means for attaching said heads thereto, sliding connections between said heads and said bar, bufi'er springs interposed between said bar and heads and ,means for adjusting the position of the respective parts of each head with reference .to each other, substantially as specified.
