I Specification of Letters Patent. f

Patented May 28,19212.

AApplication filed December. 11, 1911.y Serial No., 665,020.

ToiaZZ whom t may concern.'

Be it known that I, HARRY E. LrvrNesToN, a' citizen of the United States, residing at Smithville, in the county of Lee, State of Aimprovements in doubletrees and the object of my invention is to improve the constructionA and increase .the etiiciency of the same.

A further object of my invention is to 4provide a novelform of clip by means of 1 vwhich the doubletree may be secured to the vehicle. 4

With these and other objects 1n view my invention will be more fully described, illusof this application.

-proved v doubletree `which trated in the accompanying drawings which show a. preferred embodiment of my device and then specifically pointed out' in the claim which is attached to and forms a part In the drawings, Figure 1 is a top plan view of the doubletree.' 2 is arear elevat-ion thereof. Fig. 3` is a detailed perspt tive of the clip. Figi t isa detail perspective Voit-a partially finished clip.

Referring more specifically to the drawings, in .which similar reference lnumerals designate corresponding parts throughout, 10 designates in general the body of my imis preferably formed of wood and the rear face of which ,is straightI as shown, while the forward face tapers from the center toward the ends whereby the central portion of the lbody member is thicker' than thel ends. By this means the body member is considerably lightened while at the same time it is in no way weakened. Extending along the entire length of the rear face of the body member is a strip of 'metal 11- the ends of which are bent about the ends of the body. member and extended forwardly beyond the same and then'bentinwardly and rearwardly to form loops`12, the terminals of said loops being extended along. the forwardinelined faces of the body member.v This strip Ais secured in place by means of bolts or rivets 13 which are passedthrough the-body' of the strip,

through the body member 10 of the doubletree and also'through the terminals of the strip 11, the same bolts thereby serving both to secure the stripto the back of the doubletree and also to secure the loops in place.

This metallic strip. is preferably rectangularl in section throughout its leiigth with the eX- ception of the intermediate loop forming sections which as shown, are circular in section. Flach of the loops is provided with a. hook 14 by means ofwhich swingletrees may be attached. y

Asa means for attaching the doubletree to a vehicle I have provided an improved clip 15 formed from a single rod of metal bent intermediate its length as at 16 and having its sides extended in spaced parallel relation, said side portions being then bent inwardly to cross'eaeh other and then rearwardly, thcterminal of one side member eX- tending in parallel spaced 'relation to the 'main portion of the other side member and in spaced relation therefrom 'in lsuch a mann'er that the free ends of t-he rods are positioned one upon either side of the bight portion 16 to which, they are then secured by welding. By this means a clip is formed.

consisting of a. pair of diverging rings connected to each other throughout a port-ion of their circumference. This clip is positioned upon the doubletree as best shown in Figs. 1 and 2, in such a-manner that the bight por# tions 1S engage one upon either side of the center of the doubletree and against the inclined faces thereof, while the welded portion of the clip extends rearwardly beyond the doubletree and is provided with a ring 19 for attachment to the vehicle.

As will be readily seen strain appli'ed-'to the hooks 14 will tend to cause the bight portions 1S of the clip to be drawn together, which tendency is overcome due to the fact that the 'inclined faces of the doubletree act to hold the said portions apart. The strain therefore merely acts to Hatten the rings or loops and thus cause them to bind more tightly about the doubletree. The metallic strip 11 not only serves to. reinforce the dou'- bl etree and to form loops for the attachment Vof the swingle-tree but also acts as a wear plate to prevent injury to the doubletree which might otherwise be caused by. the

ring 19.A l

It will therefore be seen that I have provvided an extremely simple and effective forni of doubletree and one which maybeA inexpensively manufactured.v

What I claim is vThe combination wit-h a doubletree having rearwardly inclined 'forward faces, of a clip for' said doubletree comprising a metalliclportion of one 1s positioned in parallel -spaeed relation to the side portion of the other, said end portions terminating one upon either side of the intermediate` bent ortions and being secured thereto by weld- 1ng,said clip being positioned upon the doubiet-ree with the resultant spaced loops thus;

formed bearing,- against the inclined faces yof the doubletree one upon either side of the `center thereof and'with its welded ortionl extending rearwardly beyond the` oubletree.

In testimony whereof, I affix my signature, in presence of two witnesses.
