SPECIFICATION forming part of Letters Patent No. 434,197, dated. Au ust 12, 1890.

Serial Ho. 347,624:- (No model.)

To all whom it may concern.-

Be it known that we, HENRY E. PEOK, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, and PHILLIP DOEPPENSMITH, a citizen of the United States, residing at Hamden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Dies for Making Saddle and Carriage Clips; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the'figures of reference marked thereon, which form a part of this specification.

Our invention relates to an improvement in dies for making saddle and carriage clips; and the object of our invention is to simplify and cheapen the manufacture of saddle and carriage clips. The ordinary common method at present in vogue is to make the different sizes of clips by separate sets of dies, which vary in size according to the size of the clips itis desired to produce, and are quite expensive; and after the clip leaves the forming or shaping die it is put through the finishingdies, which are also expensive, and finally the clip is finished and the threads cut on the ends thereof.

In manufacturing carriage-clips according to our present invention ablank or strip is cut from a single bar of metal, which blank is of the desired length to form the clip, and the bar of metal is of any preferred shape in cross-section-as, for instance, fiat on one face and convex on the other, or hexagonal, or of any other desired polygonal shape in crossit is straight and before it is bent to form a U-shaped clip. The blank is now bent or doubled upon itself to form the letter U, with the threadediportions parallel with each other,

the bar being bent while it is cold, and after bending the blank it is heated and placed in the dies forming a part of our present invention, which impart the desired configuration or shape to the blank to form a clip, which can be finished or polished very quickly and at slight cost after it leaves the shapingdies.

We Will now proceed to a detailed description of the shaping-dies and the method of making the clips as contemplated by ourpresent invention, reference being had to the accompanying drawings, in which p I Figure 1 is a perspective view of the male and female dies, and the heading-die above the same, showing the dies separated and adapted to come together in proper alignment for shaping the bent blank. Fig. 2 is a sectional view through the dies showing a blank therein. Fig. 3 is a detail view of one of the dies,'showing the reversible plate therein. Fig. 4 is a perspective view of the blank from which the clip is made. Fig. 5 is a like view of the blank after it is bent and before it has been shaped by the dies. Fig. 6 is a similar View of a finished blank or complete clip.

Like numerals of reference denote corresponding parts in all the figures of the drawings, in which- V 1 designates the inale die, 2 the female die, and 3 the heading-die, which are used to make and shape clips in accordance with our present invention.

The male and female dies 1 and 2 are adapted to abut laterally together, and in the opposing or contacting faces of these two dies are formed the channels 4: 5, of a shape and width conforming to the shape of the clip it is desired to produce. The channels in each die are of suitable depth and shape in cross-section, and the ends of the channels open through the faces of the die which lie at right angles to the face in which said channels are formed. The channels are separated from each other the desired distance between the legs of the clips, and when the channeled faces of the male and female dies come together said channels in the dies coincide and form passages for the reception of the legs of the clip, the shape of the passages in crosssection conforming to the shape in cross-section of the legs of the clip.

In one of the faces of the male and female dies, at right angles to the channeled faces thereof, we provide a longitudinal recess 6, which lies at right angles to the channels 4 5, and this recess is of such width as the space between the contiguous edges of the parallel channels in the dies. The recess 6 is quite deep, and it has vertical walls 7 for a portion of its depth and inclined walls 8, which flare from the vertical walls 7 to the outer face of the die. In this recess 6 of the male die we provide a reversible and adjustable plate or post 10, around which the head or bent part of the clip is fitted, and which, in connection with the heading-die 3, operates to impart the desired configuration to the head of the clip. This plate or post 10 fits snugly and neatly within the recess 6, with its exposed face on the plane of the line of juncture of the Vertical and flared walls of said recess, and one end of this plate or post is projected or extended beyond the male die, so as to be received within the recess 6 of the female die when said dies properly coincide. This plate or post conforms in cross-section to the desired contour of the inner faces of the clip, and said plate or post can be reversed side for side and end for end when its faces become worn through use, in order to present a multiplicity of surfaces in a single plate and enable the same dies to be used to produce perfect work in large quantities. WVe attach importance to this reversible and adjustable post, as it enables us to renew and repair the part of the dies which is most subjected to wear at a slight expense. The adjustment of this plate or post is very simple and quickly performed, as said plate or post is secured in place between the walls of the recess bya single screw 11, which passes through a perforation in the post and operates in a threaded socket formed in the die.

The heading-die 3 has a protuberance 15 formed on one surface thereof, and the ends of this protuberance are beveled transversely to the longitudinal axis of said die, the inclination of the beveled ends 16 on the heading-die corresponding to the flared walls 8 of the male and female dies to adapt said protuberance to fit snugly within the space between the flared walls of the recesses 6 6 in said dies. This protuberance is formed with a central channel 17, which extends in the direction of the length of the die and has its ends opening through the flared or beveled ends 16 on the protuberance 15, and this heading-die is adapted to enter the recesses 6 immediately over the channels 4 5 in said dies and the end of the plate or post, so as to act directly on the head of the clip.

The dies can be adapted or fitted for use in any ordinary heading-machine, which is familiar to every one'skilled in the art to which this invention relates.

To produce a clip in accordance with our invention, we first cut a blank 20 from a long bar of metal of the desired shape and size in cross-section, and while this blank is straight the ends thereof are rounded and screwthreaded, as at 21, because this Work can be more advantageously performed while the blank is straight than after it is bent. \Vhile the blank is in a cold condition it is bent or doubled upon itself, as in Fig. 5, by being placed in a suitable bending-machine and having a plunger of the desired width act upon the middle of the blank, and thus double the blank to provide the parallel legs, which are spaced apart the desired distance. After having been properly bent the blank is heated and placed in the channels of the male and female dies, with its doubled or bent portion around the protruding ends of the post or plate, and the male, female, and

heading dies are now closed upon the heated blank to impart the desired configuration to the legs and head of the clip. The dies are now operated to release the clip, and the latter is removed and finished in any preferred By the use of the dies constructed essentially as shown herein we are enabled to make clips of any desired length, as the legs of the long clips are free to protrude through the open ends of the passages formed by the channels in the male and female dies.

The dies are simple and durable in constructiOn, can be easily repaired when the parts are worn, and they are cheap, as only one set of dies is necessary for any length of clips of a uniform or standard width.

The male and female dies may be used or reversed end to end,which in practiceis very desirable.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The herein-described dies for making carriage-clips, comprising the male and female dies having the corresponding channels in their adjacent faces, and a post or plate fixed to or rigid with the male die and extending at right angles across the passages formed by said channels and between the same, as and for the purpose described.
