UNITED STATES PATENT OFFICE.

URIAH BILLIN GS, OF NEW BEDFORD, MASSACHUSETTS.

Specification forming part of Letters Patent No. 33,692, dated November 12, 1861.

To @ZZ whom, it may concern.-

Be it known that I, URIAH BILLINGs, of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Machinery for Making Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specicatiou, in whichk Figures l and 2 are vertical sections at -right angles to each other of a machine for forming horseshoes constructed according to my invention. Fig. 3 is a plan of the same.

Similar letters of reference indicate corresponding parts in the several figures.

To enable others skilled in t-he art to make and use my invention, I will proceed to describe its construction and operation.

A is a strong bed-plate to which all the parts of the machine are attached.

B is a goose-neck casting bolted to the bedplate and having secured to it the stationary die C, whose thickness is equal to the intended thickness of the shoe.

D is the reciprocating carriage' tted to slide horizontally in parallel ways Ct d, secured to orformed upon the bed-plate and having imparted to it by any suitable means a proper reciprocating movement relatively to the die C.

E E are the two arms, each of which carries one of the two forming-rollers F F, said arms being pivoted at their front ends to the carriage D by pivots b b,upon which they swing horizontally. Besidestheforming-rollers the said arms carry each a guide-roller G, and each arm is extended rearward beyond its rollers F G, as shown at E', to form a rest-ingplace for the shoe-blanks. The forming-rollers have square grooves c o in their peripheries of a width equal to the intended thickness of the shoe.

II II are the fixed guides, which direct the guide-rollers in such a manner that during the movement of the arms and rollers with the carriage the formingrollers F F have the necessary movement relatively to the die C to bend the blank round the said die and to narrow the shoe at the heel. These guides, which are situated at the sides of the die C,

are adjustable by the set-screws d d, which screw into upward projections of the bedplate toward and from the die for the purpose of adapting the machine to shoes of various sizes and widths.

I I are the grippers, attached to or formed upon the front extremities of two levers J J', which work upon separate iixed fulcra e e, secured in a xed standard K, erected upon the bed-plate between the roller-arms E E and at a short distance in front of the die C. The front portions of the levers J J receive between them two rollers L L', -which are attached one above the other to the reciprocat` ing carriage D. The front portion of the lower lever J is held up against the lower roller L by a spring M, and the front portion of the upper lever J rests by its own weight upon the upper roller L, and the said spring and the weight of the upper lever tend to keep the jaws of the grippers open.

The operation of the machine is as follows: The blanks (represented in red outlines in the several iigures) having been rolled to produce the creases of the shoe and cut olf to the proper length and heatedto a suitable heat, are fed one at a time into the machine from one side thereof onto the top of the parts E E of the roller-arms at the time when the carriage has been drawn to its full extent forward, or in the opposite direction to the arrows shown upon it in Figs. l and 3, the middle of the blank being placed opposite to the center of the die. The carriage then moving forward in the direction of the arrows forces the rollers L L between the levers `J J and closes the grippers upon t-he blank, and the continued forward movement ot' the carriage brings the forming-rollers F F into operation ou the blank and bends it round the die, the guide-rollers G G being so directed by the guides H Il as to force the arms E E and rollers F F toward each other in such a manner as to effect the narrowing of the heel of the shoe. As the carriage returns in a forward direction, the grippers are opened by the action of the spring M and the weight of the upper lever J, and the arms are forced apart by the rollers F F passing a second time along the sides of the shoe, and as soon as the rollers have entirely passed the shoe the latter,

which duringi the fornnition has been sup- J, in combination with the trm'eling rollers ported upon the bottoms of the grooves c c, L L and the extension-arms E E', substandrops through a holefin the bed-plate. tially as herein shown and described.

XVhat I claim as my invention, and desire 'lhecombination of the vertical grippingtO Secure by Letters Patent,islevers J J with the forming-rollers F F and 1.
