IMPROVEMENT IN METALLIC-FENCE TWISTERS.
Specification forming part of Letters Patent No. 216,779, dated J nne 24, 1879; application filed May 12, 1879.
To all whom it may concern:
Be it known that we, JACOB BRINKERHOFF and WARREN M. BRINKERHOFF, both of A11- burn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Metallic-Fence Twisters; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure 1 represents a top or plan view of three ordinary fence-posts, with the ends of a section of flat metallic barb fencing attached by means of suitable staples to the two outer posts. It also represents said barbed fencestrip as being twisted by one of our improved met-allie fence twisters preparatory to said strip being dropped and inserted into a looking and holding fence-hook provided for the purpose, which is secured in the center post. Fig. 2 represents a vertical section through the barbed fence-strip, taken on line A B, Fig. 1, looking in the direction indicated by arrow 1, and showing a side view of our improved fence-twister and other parts illustrated in Fig. 1; and Figs. 3 and 4 repre sent, upon an enlarged scale, a side and top or plan view, respectively, of aforesaid metallic-fence twist-er.
Our invention relates to metallic fence twisters for twisting barbed fence-strips such as described and shown in the Letters Patent granted to Jacob Brinkerhofl', October 24, 1876, No. 183,531, and April 8, 1879, No. 214,095, said fence-strips being secured to every other post by means of suitable fencestaples, and then twisted by our improved device, and afterward secured to their respective posts, as hereinafter more fully described.
To enable those skilled in the art to which our invention belongs to make and use the same, we will proceed to describe it more in detail.
In the drawings, 0 O and 0 represent ordinary fence-posts; D, a section of flat metallic barbed fencing, and E our improved metallic-fence twister for twisting the same.
The operation of securing and twisting a fence-strip is as follows: The strip of fencing is first secured to every other post 0 O by means of suitable fence-staples, being drawn as taut as possible during the aforesaid operation. The twister is next applied to the strip, (said twister being provided with an angular slot, a, in which to insert the fencestrip, and with shoulders b b, for preventing its springing out,) when it is then turned and the strip thereby twisted. Having been sufliciently twisted, it is then dropped and inserted into a similar slot to slot a, formed in the upper side of a fence-hook, F, secured in the center post, 0, when the twister is then removed and the operation completed.
In this instance the fence-strip D is represen ted as being twisted toward the right when looking in the direction indicated by arrow 1, thus bringing said strip against the side of slot or nearest the fence-post, as represented in Fig. 2 of the drawings. If preferred, it may be twisted in the opposite direction, or the twister applied to the same upon the other side of the fence-post.
Those skilled in the art to which our invention belongs will readily understand and appreciate the great practical advantages derived from employing a twisting device such as herein shown and described. It is not only strong and durable, but of very simple construction, and performs its office perfectly, while at the same time by its use the necessity of twisting the fence-strips when they are manufactured is obviated, thus enabling them to be coiled more compactly for shipment.
Then, again, by the use of the peculiarlyconstructed fence-hook F (which forms the subject-matter of anotherand separate application for Letters Patent tiled by us of even date herewith) and our twisting device E, the
different sections of the fence can be tightened up with great expedition and ease by simply lifting the fence-strip D out of slot 0/ in the hook F by means of the twister E, and then give it a half-turn or more before replacing it in slot a, where it is held by its upper edge catching under one of the shoulders in hook F, corresponding with shoulders b in the twister E.
Having described our improvements in metallio-fence twisters, What We claim therein as new and of our invention, and desire to secure by Letters Patent, is-
As an improved article of man ufaeture, a metal-fence twister, E, provided with an angular slot, a, and shoulders I) 13, substantially as and for the purposes set forth.
