Application May 2, 1945, Serial No. 591,613 1 Claim. (01. 54-7’) 1 , The present invention relates to a new and useful improvement in hackamore bits for use in threaded portion || outwardly of the lever, the nut I 5 being formed with an inwardly projecting annular collar I6 forming a bearing for the smooth portion l2 of the mouth piece and on trol the movements of the horse. ‘ An important object of the present invention Ci which the lever is mounted for pivotal move is to provide means for exerting pressure on a ment. The inner end of the collar I6 abuts the nose strap and jaw strap simultaneously by a outer end of the threaded portion It to prevent binding of the lever on the collar I6. pulling force exerted on the reins. The cheek plate l3v is formed with an opening More speci?cally, the invention embodies the l1 adjacent its upper portion on the inner side provision of interengaging gear segments oper ated by a pulling force exerted on the reins to of which a screw I8 is countersunk, the screw having a ?anged nut l9 threaded on its outer increase the pressure on the nose and jaw straps. end and also provided with an inwardly pro A further object of invention is to provide jecting collar 20 on which a gear segment 2| is a device of this character of simple and practical rotatably mounted, the gear segment 2| being construction, which is strong and durable, neat driving horses and designed to effectively con and attractive in appearance, e?icient and re engaged with a gear segment 22 formed on the upper end of the adjacent lever.

Figure 2 is a side elevational view. liable in use, and otherwise well adapted for the purposes for which the same is intended. Other objects and advantages reside in the Figure 3 is a rear elevational view. Figure 4 is a vertical sectional view taken sub stantially on a line 4—4' of Figure 2. Figure 5 is a perspective view of one of the ?anged retaining nuts and Figure 6 is a side elevational View showing the device in use. Referring now to the drawings in detail where in for the purpose of illustration I have dis closed a preferred embodiment of invention. The numerals 5 and 6 designate a pair of rein levers which are curved rearwardly at their lower ends and provided with eyes 1 by means of which the reins 8 may be attached thereto. The upper portion of the levers are connected ' by a mouthpiece 9 in the form of a smooth bar adapted for insertion in the mouth of a horse, each end of the mouth being formed with an inner threaded portion l0, an outer threaded 45 portion II, and an intermediate smooth portion [2, all of successively reduced diameter as in dicated in Figure 4 of the drawings. A cheek plate I3 is threaded at its lower por An extension 21 projects forwardly from the gear segment 2| and is formed with a slot 28 for attaching a nose strap 29 thereto adapted for extending transversely over the nose 3|] of the horse. The upper end of the cheek plate I3 is also formed with a slot 3| for attaching a head strap 32 thereto. Accordingly, in the operation of the device and with the levers 5 and 6 positioned at opposite sides of the head of the horse and each opera tively connected at theirv upper ends with a gear segment 2| pivoted on a cheek plate l3 and with a jaw'strap 25, nose strap 29 and head strap 32 attached in the manner as indicated in Figure 6 of the drawings a pulling force exerted on the reins 8 will cause a rotation of the levers 5 and 6 on the collars l6 carried at the smooth portion I2 of the mouth piece 9 whereby to rotate-the gear segments 2| and cause the nose strap 29 to be tightened over the nose of the horse as vwell as to cause the jaw strap 25 to be tightened under the jaw of the horse and thus serve to bring tion on the inner threaded section ID of the 50 the horse under control when desired. mouthpiece 9 and extends upwardly therefrom, In view of the foregoing description taken in the inner side of the cheek plate abutting the conjunction with the accompanying drawings it shoulder l4 formed at the inner end of the is believed that a clear understanding ofv the con threaded portion ID. struction, operation and advantages of the device A ?anged nut I5 is threaded on the outer 55 will be quite apparent to those skilled in the art. 21,413,426 . 3 . ‘ ; 4 A more detailed description is accordingly deemed thereto, extensions projecting rearwardly from unnecessary. the levers, a jaw strap connected to said ex tensions, said levers having gear segments It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same formed at their upper edges, gear segments ro tatably mounted on the cheek plates and opera tively engaged with the gear segments ?rst men tioned, extensions projecting forwardly of the hended by the spirit of the invention as herein gear segments, and a nose strap connected to described and claimed. said last named extensions, said jaw and nose I claim: A hackamore bit comprising a pair of check 10 straps being compressed respectively under the jaw and over the nose of an animal upon a pulling plates, a mouth bar rigidly connecting the cheek is susceptible to certain changes fully compre plates, head straps extending upwardly from the cheek plates, a pair of levers pivoted on the mouth ' bar and adapted for attaching a pair of reins force exerted on the reins.
