To all whom it mag concern MAHLON- HAMLIN, OF GATAWISSA, ASSIGNOR TO HIMSELF AND BENJA v MIN WELGIL'OF DANVILLE, PENNSYLVANIA.
Letters Patent No. 105,568, dated July 19, 1870.
IMPROVEMENT m som-rnnsanme MACHINE.
The Schedule referred to in these Letters Patent and making part of the same- Be it known that I,MA11LON HAMLIN, of Catawissa, in the county, of Columbia, and in the State of Pennsylvania, have invented i certain new and useful Improvements in Heads for Bolt-Gutters; and do herei by declare that the following is a full, clealyand exact description thereof, reference being had to the accompan ying drawing and to theletters of reference marked thereon, making part of this specification.
The nature of my invention consists in the construction and arrangement of a head for bolt-cutters,
as will be hereinafter fully set forth.
In order to enable others skilled in the art to which my intention appertaius to make and use the same, "livill now proceedto describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a front view of the head, part of the faceplate being removed, and a r Figure 2 is a horizontal section of the same. l A represents the head of the bolt-cutter, having in its front end three slots at equal distancesapart, and
radiating .fromthe center. In these slots or mortises the dies B B are placed. The outer ends of I the dies 13B are beveled, as shown iuthe drawing, and at a .suitable point on their under side is a slot, in which is inserted the outer endof: a spring, 0, which is secured in a recess on the 1 head A.
The object of the springs O O is to throw the dies outward after the bolt has been cut.
A'sle'e ve, D, is placed around the head A, and moves longitudinally on the same to force the dies in ward, orclose them so as toCcut the bolt.
In the frontend of the sleeve Dis a circular re f cess, in whichis placed a compensating ring, E. This ringis innnediat'ely around the head A, and provided on its inner circumference with three bevels, as shown in figJl, said bevelscorrcsponding with the dies. The
ring E moves with the sleeve 1) longitudinally on the head A, and the beveled endsof the dies, coming in contact with the inner surface of the ring, causes the dies to close. I
manner: I I I One or more screws, I, are inserted in the outside of the ring, andsaid screws pass through slots in the sleeve; so that the ring can be moved at will the outside without disturbing either the head or the sleeve. The object of this motion is to compensate for the wear and tear of the dies.
Supposing the deepest parts of the bevels on the inside surface of the ring E are'onc inch, and then gradually lessening till they reach the inside surface of the ring, and thering is set so that the dies are operated at this dcepest portion of the bcvels. Then, when the dies are worn out, so that they must be re-cut, they, of course, lose a certain portion in size; this is made up by turning the ring E far enough to make the dies move inward the same distance as before; hence I call this ring a compensating ring.
By the proper adjustment of this compensating ring" the bolts may also be cut so as to fit the nuts loose or tight, as may be desired, and for this purpose the slot or slots in the sleeve D, through which the screws I pass, may he graduated. The front of the head A is covered by a face-plate, G, which confines the dies in their proper places.
Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-- The combination and arrangement of the head A, dies B B, springs G O, sleeve 1), compensating ring E, and face-plate G, all constructed as described, and Operating substantially in the manner and for the purposes herein set forth.
In testimony that I claim the foregoing, I have hereunto set my hand this 3d day of February, 1870.
MAHLON HAMLIN.
