IMPROVEMENT IN MACHINES FOR TRINIMING STIRRUPS.
Specication forming part of Letters Patent No. 129,273, dated July 16, 1872.
To all lwhom it may concern:
Be it known that I, PETER FEEMAN, of Lima, in the county of Allen and State of Ohio, have invented a new and valuable Improve- :ment in Machine for Trimming Stirrups; and I dohereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference be-A ing had to the annexed drawing making a part of this specification, and to the letters and gures of reference marked thereon.
Figure l of the drawing is -a representation of a vertical sectional view of my invention. Fig. 2 is a horizontal section of the same.
This invention has relationto a machine for rounding and nishing the ends of bent wooden stirrups; and consists in the construction and novel arrangement of a knife, its operating devices, and of a notched bed for holding the stirrup during the finishing process, all as hereinafter more fully described.
Referring to the accompanying drawing, A represents a horizontal bed supporting the working parts of this machine, and notched at a to receive the notched cross-bar joining the two ends of a stirrup, so that the longer end of the same may be brought under the knife. The bed should be constructed principally of cast-iron, but the part immediately under the knife may be made of soft metal, so as not to injure the edge thereof when the knife strikes it. B represents a standard, slotted at its upper end, andv armed with an eccentrically pivoted lever, O, the head D of which works in contactwith the upper end ofthe knifeshank E and causes said knife to be pressed down when the lever-arm is lowered. The knife-shank plays through two slotted bracket-plates, F, projecting from the ends of the back-plate G 5 and, to prevent any variation in the exactness of its stroke, is preferably made rectangular. A spring, H, is coiled around the shank between the plates F, and has the effect of raising the knife with the upward movement of the lever-arm. I indicates the knife, which is shaped in horizontal section somewhat as the letter U, or of a concavoconvex form. The lower edge is sharpened,
and trims the end of the stirrup at once to the proper form when pressed down upon it.
What I claim as my invention, and desire to secure by Letters Patent, is
The stirrup-trimmer, having the notched bed i A, standard B, eccentric lever C D, concavoconvex knife, I, shank E, and spring H, combined substantially as specified.
In testimony that I claimthe above I have hereunto subscribed my name in the presence of two witnesses.
I PETER FEEMAN.
