IMPROVEMENT IN MACHINES FoR SCORING scREw-CAPS.

Specification forming part ofLetters Patent No. 147,163, dated February 3, 1874; application filed December 3, 1873.

To all whom' it may concern:

Be it known that I, FRANK W. PERRY, of the city and county of Camden and State of N ew Jersey, have invented a new and useful Apparatus for Scoring Sheet-Metal Screw-Gaps; and I do hereby declarethe following to be a clear and exact description of the nature thereof, sufiicient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings Inaking part of this specification, in which- Figure l is a central vertical transverse section of the device embodying my invention. Fig. 2 is a front view of a detached portion. Fig. 3 is a horizontal section in line xx, Fig. 2. Fig. 4 ris a front view. Fig. 5 is a front view of a detached portion enlarged. Fig. 6 is a top view of a scored screw-cap. Fig. 7 is a central section thereof.

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

It is well known that sheet-metal screw-caps are applied to cans and other packages to contain oil and other uids, and that it is important that the top or central portion of the two sections or parts of the caps are solid or closed to prevent leakage between the joints thereof. Itis, however, essential that when the can or package reaches its destination, one of the sections or caps has its center or top cut away to form an opening for the discharge of the fluid.

My invention is designed for the purpose of scoring, half-cutting, or thinning a portion of one section of the cap, whereby said portion is in condition to be readily cut by a knife or other suitable implement. The invention consists in a rotary knife-cutter or bit. It also consists of a feedingspindle. It further consists of a spindle for holding the cap while being cnt. It also consists in means for imparting a dwell to thefeeding-spindle. It also consists in a screw for regulating the depth of the cut or score.

Referring to the drawings,'A represents the main shaft, having bearings in a suitable frame or support, B. O represents a shaft which receives motion from the shaft A, and imparts motion to a horizontal shaft, D, suitable intermediate gearing being provided therefor, and

the shaft l) carries, at the end opposite to its l geared end, a cam, F.. A pulley, F, is attached to the shaft C, and, by means of a band, G, and

arranged spindle, J, which is mounted on the frame B and has an opening its entire length, and through the opening passes a spindle, K, whose upper end is angular and passes through an angular opening in an arm, L, which holds and guides the upper end of said spindle K, while the main portion of the latter is within the spindle J, whereby' said spindle K is permitted to rise and fall within the spindle J, but without having rotary motion therewith. M represents a spindle, which is mounted on suitable arms of the frame B and arranged vertically under the spindles J K. The lower end of this spindle M carries a screw, N, which rests on the cam E, and its upper end is formed with or has connected to it a head, P. A spring, Q, is arranged with the spindle M and proper portions of the frame B, for forcing the said spindle downwardly and against the cam E. The lower en d of the inclosed spindle K carries a head, It, and bearing against its upper end is a spring, S, whose tendency is to keep the spindle K to its lowest point.I T represents a knife, cutter, or bit, which is connected to the lower end of the spindle J, and in the present case said knife is tted in a groove, a, in the spindle, a collar, b, passed around the shank ofthe knife, and a screw, c, introduced through the collar to bear against the shank of the knife. The cam E is so constructed that'when, in rotation, it raises the spindle M to its highest point, it reaches the point d. Then, the face df, being the are of a circle whose center is the shaft D, bears against the spindle M without elevating the same, thus causing what is termed a dwell of said spindle, after which the spindle clears the point fof the cain E and drops to its normal position. c

The operation is as follows: A screw or other spindle M, and, as the latter is elevated by the cam E, the cap is advanced toward the knife T, land comes in contact with the inclosed spindle K, which, while being raised by the raising of the spindle M, bears against the metal cap, and when the spindle M is at its highest point pulley H, imparts rotary motion to a verticallysheet-metal cap is placed on the head of the the'said cap is iirmly held by the spindle K,

due to the action of the spring S. When said highest point of the spindle M is reached, then the dwell oeours, and the knife Tis in Contact with the upper face of the metal eap, and, in its path of rotation, caused to eut a channel in the said upper face of the cap, near the periphery thereof, this constituting the score of the eap (see g, Figs. 6 and 7,) and vcompleting the scoring operation. The spindle M then drops, the cap is removed therefrom, and a fresh eap applied. The degree of penetration of the knife is readily adjusted by the screw N in the spindle M.

Having thus described 1ny invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The knife T, having` a rotary motion and operating for scoring the metal cap presented to it, substantially as set forth.

. 2. The feeding-spindle M, having a risingand-falling motion and operating for presenting the lnetal cap to the scoring-knife, substantially as set forth.

3. The holding-spindle K, in connection withA the feeding-spindle M and scoring-knife T, substantially as and for the purpose set forth.

4. The risingand-falling spindle K inolosed within the rotary spindle J, in combination with the feeding-spindle M arranged thereunder, and raising the said spindle K, in the manner and for the purpose set forth.

5. The combination, with the feeding-spindle M and scoring-knife T, of the cam E, oonstrueted to impart a dwell to the said feedingspindle, as set forth.

6. The adjusting-screw N, in combination with feeding-spindle M of an apparatus for scoring metal caps, substantially as set forth.
