UNITED STATES PATENT OFFICE.
JUNIUS G. LOGGINS AND PARKHRST P. WILKINS, OF WILLISTON, VERMONT.
IMPROVEMENT IN HOP-LOCK CUTTERS.
Specification forming part of Letters Patent No. 145,956,`datcd December 30, 1873; application filed February 20, 1873.
To all whom it may concern:
Be it known that we, JUNIUs G. LOGGINs and PARKHURsT P. WrLKrNs, of Williston, Chittenden county, State of Vermont, have invented certain Improvements in Hoop-Lock Cutters; and we do hereby declare the following, taken in connection with the drawings which accompany and form a part of this specication, is a description of our invention sufficient to enable those skilled in the art to practice it.
This invention relates to the class of machines which are used for the purpose of cutting the locks in wooden hoops, and which has been heretofore commonly donel by hand, owing to the imperfect operationof the machines which have been constructed for the purpose; and it consists in the construction and arrangement of the revolving` cutters; also, in the devices for holding the hoop to be cut so that it may be applied to the different cutters for cutting the lock and chamfering the hoop without its being unclamped.
In the following description, similar letters of reference indicate corresponding parts in the different figures.
Figure 1 is a perspective view of the machine complete. Fig. 2 is a side view of the swinging hoop-clamp, and Fig. 3 shows the iinished hoop.
A represents the frame of the machine. B is the driving-pulley, which is secured upon the shaft C. D is a pulley on the shaft C, from which motion is conveyed, by the belts E E', to pulleys F F, and by them imparted to the cutter-shafts G G'. The cutter-heads H I'are hollow cylinders secured upon one end of the shafts G G. They are furnished with suitable cutters, J and K, secured in a proper position by means of screw-bolts. The cutterhead I `is also provided with a cutting-spur placed in front of the cutter K, which forms the square shoulder ofthe lock. It will be observed that the belt E is crossed, while the belt E runs straight, thus causing the cutterheads to revolve in opposite directions, giving them both a tendency to hold the hoop in its bed during the operation of forming the lock. In a suitable position upon the shaft G is placed a circular saw, which cuts oil any extra length of hoop at the same time that the lock is being formed, andrequiring no attention from the operator. l is an oscillating shaft, to which the swinging hoop-clamp and carrier R is secured, being adjusted with relation to the cutters by the nuts 'S S. T T are adjustable jaws, which hold the hoop against the plate or jaw U, when acted upon by means of the handle V. A sliding gage, W, for determining the length of the hoops, is made adjustable upon the swinging clamp,- and is provided with a pin or hook, do, against which the shoulder ofthe lock iirst cut is placed while cutting the one upon the opposite end of the hoop, so as to obtain a uniform distance between the shoulders. A planing disk, N, provided with suitable cutters O O, is secured upon one end of the driving-shaft C, and is used for the purpose of tapering the ends of the hoops.
In operating this machine a hoop is placed upon the carriers and secured by the clamp. It is then swung against one of the cutters for the purpose of cutting the notch, after which, without being released, it is brought in contact with the other, which cuts the necessary chamfer upon the opposite side, the clips cut from the hoop passing into the interior of the cnt ter-heads and out of their open ends, thus presenting no obstruction to their operation.
Having thus described our invention, we claim- 1. The cutter -heads H I, in combination with the swinging hoop, clamp, and carrier, as and for the purpose herein set forth.
2. The swinging frame R, provided with the clamping-jaws T T, plate U, and adjustablev
