ART OF FORMING CHEEK-PIECES FOR BRlDLE-BITS SPECIFICATION forming part of Iietters Patent No. 258,166, dated May 16, 1 882."

Application filed December 10, 1851. (No model.)

To all whom it may concern:

Be it known that we, THOMAS E. VAN N ESS and DANIEL MALONEY, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in the Method of Forming Cheek-Pieces for Bridle-Bits and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of two blank cheek-pieces as they leave the forming-dies. Fig. 2 is a like view of one of the same after the fin or surplus metal has been trimmed away. Fig. 3 is a perspective view of I said cheek-piece after having passed through the finishing-die. Fig. 4 is alike view of the dies used for forming said blanks. Fig. 5 is a perspective view of a blank cheek-piece, in which the parts are arranged differently from that before named. Figs. 6 and 7 show respectively said blank after trimming and the completed article, and Fig. Sis a perspective view of the dies employed for producing said lastnamed blank.

Letters of like name and kind refer to like parts in each of the figures.

Heretoforeit has been customary to formthe cheek-piece of a bridle-bit from a bar of iron having one of its ends bent around in the form of a circle, which blank was then heated to a welding temperature and subjected to the action of dies within a drop; but such method has proved objectionable from the fact that it has been practically impossible to make a perfectly-welded joint atthepoint where the coiled end of the baroverlapped thebody of the cheekpiece.

To remedy this difficulty and to render easy the production of a perfect solid article is the design of our invention.

It consists principally, as an improvement in the art of making cheekpieces for bridlebits, in raising said cheek-pieces in relief on opposite surfaces of a plate or bar by dies that, while producing substantially the proper form and dimensions in cross-section, shall, by an irregular or distorted line of the raised por tion thereof, give to the ring or bow in one direction a reduced sectional area to bring the article in the ensemble within greatlyweduced limits, (whereby a saving in stock and in the cost of dies and in the power to operate the same is effeotech) then trimming 0d thefins and intermediate plate of metal, and finally opening out said ring or bow to its proper form and dimensions, substantially as hereinafter specified.

It consists, further,in the dies, substantially as and for the purpose hereinafter shown.

In the use of our method we take square bariron having the relative proportion of measurement in cross-section of thrce-eighths by fiveeighths of an inch, and after heating the same place it between two dies, A and B, and sub ject said heated bar to several blows of the upper die, A. Each of the dies Aaud B is provided within its face with a half-round recess, a or b, which corresponds in outline to the form of a cheek-piece, O, with its ring part c and tail-piece 0 closed inward, so as to occupy'but little space laterally, which dies, operating upon the heated bar, as before described, produce the blank C shown in Fig. 1, the surplus metal being forced horizontally outward in each direction in the form of a tin, 0 The blank 0 passes from the forging-dies to trimming-dies, which remove the tin c and leave it in the form shown in Fig. 2, al'ter which the ring part c is spread and given the form of a circle by dies, or by any other desired means,

such operation completing the forgingof the cheek-piece and producing the article shown in Fig. 3. r l

There are various other forms in Which'the ring part and tailpiece maybe arranged in order to cause them to occupy little lateral space and to enable them to be forged from a narrow bar of iron, and it will sutticiently illustrate the principle to describe one of such forms.

In Figs. 5, 6, and 7 are shown respectively a blank chcekpiece before trimming, the same after trimming, and the completed cheek-piece, and in Fig.8 the (lies used'for forming said blank, the latter being a modification of the blank before described, and having its tailpiece bent around beside and parallel with the ring part, instead of being extended lon gitudinally beyond the same. This form ofblank is not, however, deemed as advantageous as that shown in Fig. 1, as wider iron is required for its production and there is more waste from trimming.

The form-of blank shown in Fig. 1 permits the production at the same time of two within one pair of (lies, as seen in Fig. 4, with considerable economy as regards waste of material. Two of the blanks shown in Fig. 5 may 31S0 'l)6.])l0(lll0(d at one time by one pair of dies; but less economy results in the latter than in the former case.

Having thus fully set forth the nature and merits of ourinvention, what we claim as new lS 1. As animproveinent in-the art; of making cheek-pieces for bridle-bits, raising said checkpieces in relief on opposite surfaces of a plate or bar by dies that, while producing substantially the proper form and dimensions in crossseetion, shall, by an irregular or distorted line of the raised portion thereof, give the ring or bowin one direction a reduced sectional area to bring the article in the ensemble within 20 greatly-reduced limits, (whereby a saving in stock and in the cost of dies and in the power to operate the same is effected.) then trimming ofl' the fins and intermediate plate of metal, and finally opening out said ring or how to its proper form and dimensions, substantially as specified.

2. The dies, as described, and shown in Fig. 4, substantially as and for the purpose shown. In testimony that we claim the foregoing we have hereunto set our hands this 1st day of December, 1881.
