MACHINE FOR SIZING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 316,129, dated April 21,1885.

Application filed January 29, 1884. (No model.)

To all whom it may concern.-

Be it known that I, AMOS DICKERMAN, a citizen of the United States of America, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machines for Sizing Paper Tubes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for sizing paper tubes for cartridge-shells so that they will be uniform in size and lit the bore of the gun.

The invention consists in novel combinations and new parts, as the same are hereinafter more fully set forth and claimed.

Figure 1 is a perspective view of the machine. Fig. 2 is a central vertical section of the slide and of a portion of the turret-head. Fig. 3 is a rear elevation of the circular disk. Fig. at is a View of a paper tube. Fig. 5 is an enlarged side elevation of a part of the frame with a feeding attachment secured thereto. Fig. 6 is a cross-section of this attachment, and shows one of the pieces for holding the tube. Fig. 7 is an enlarged plan view of this attachment and parts connected to it. Fig. 8 is a plan view, partly in section, showing the means for revolving the turret-head.

To enable others to make and use my machine, I will describe it in detail, and its mode of operation.

The oblong frame Ahas two flat strips with beveled edges, which, with the beveled surfaces on the parts to which they are bolted, form V-shap'ed ways 0 for the slide D. The slide D has an opening, E, lengthwise through it, and V-shaped edges F, which fit in the ways 0 of the frame. It also has the projection R, through which a pin passes to hold one end of the connecting-rod to the slide. The shaft G turns in bearings in the slide, and to it the turret-head H and ratchet-wheel p are fastened. A hole, 1', is made in the slide for holding the pin j, which is forced successively into equidistant holes Z Z in the lower part of the turret-head and prevents its turning.

It will be understood that the base of the turret is provided with a series of these holes Z Z, arranged at regular intervals. The lower end of the pinj within the hole or recess t is supported by a spring, k, as shown in Fig. 2. A'lever, m, enters a slot in the pin j. This lever is pivoted in an opening in the slide, and to its outer end is journaled a roller, a. An

inclined way, 0, is pivoted on a stud in the frame, and its thin end is supported by a pin in such a manner as to allow the roller n to run up the way and withdraw the pin j from its engagement with the turret. turret is turned, the roller 12 will have passed beyond the way 0, and that end of the lever at will have dropped low enough to cause its opposite end to elevate the pinj into the next hole Z, and the roller it will pass under the inclined way 0 as the direction of the movement of the slide is changed. The pawl q turns on a stud in the frame, and its wide and heavy end rests on the frame or apin in the frame. As the ratchet engages the pawl as the slide moves toward it, the shaft G and the attached parts are turned an eighth of a revolution. As'

the slide moves in the opposite direction, the pawl slips over the under side of the teeth on the ratchet instead of over the ends in the usual manner.

When the These devices are so arranged and timed 7 head the ratchet engages the pawl and turns the shaft'G. The circular disk U and the gear-wheel W are fastened on the shaft or, on theouter end of which isa collar (not shown) .to hold it in the frame y, in which it turns. The disk U has a dovetailed groove, 25, in which the slide V is adjusted to regulate the movement of the slide D. It is held in place by a bolt passing through the disk with a nut on its end. the slide and forms a pin for holding one end of the connecting-rod S. The shaft of the smaller The other end projects in front of j gear-wheel .2 turns in a bearing in the frame and carries two pulleys, 2', one of which is loose on the shaft. The turret-head H has eight round arms, h, of such size that they will snugly fit into the paper tubes. These arms are brought in line of the direction of the die It by the pawl and ratchet. The die It is made of steel and preferably in two pieces less than semicircles. so that the parts may be brought nearer each other as they wear. It is hardened and poli and is still turning.

ished. The size of the hole in the die isrthe size to which the tubes are to be reduced. It is fastened in the spindle m, which carries a driving-pulley, 0, and turns in the headblock a.

The machine as thus constructed is operated as described, and the tubes may be placed upon the arms of the spider by hand; but when desired an attachment shown in Figs. 5, 6, and 7 may be employed to hold the tube in position to be received upon an arm of the spider as the latter is thrust away from the die. This attachment will now be described. The attachment A, Fig. 5, is bolted to the end of the main frame opposite the die k, and to it is hinged or pivoted the abutment f by means of the bolt The pieces I), that are pivoted to plates 0 on this part of the frame, have the curved grooves or notches e, and are made in the form shown in Fig. 6. They are held in position by the springs d. In these grooves e the paper tubes are placed. The pieces b may be varied in construction for example, the springs may be omitted and a central part of the piece may extend down ward below or under the grooves and be made heavy enough to hold the pieces in position, or two thin flat springs, bent in the proper form. and inserted in the frame, may be substituted for each piece. The abutment f is pivoted on one side of the frame, as shown at g in Fig. 5; but it may be pivoted or hinged in various waysfor example, an arm attached to the frame may extend upward and over it and the abutment be hinged to the arm. The object of the pivot g is to allow the abutment to move out of the way as an arm of the turrethead passes over this part of the attachment. The spring 13 is fastened to the frame and comes against the side of the abutment.

The several parts of the machine being constructed as above described, its operation is as follows: As the turret-head moves toward the abutment an arm of the head passes up one of the grooves e in the pieces I). \Vhen the arm reaches the abutment under the movement of the slide D, that carries the' turret, the ratchet reaches the pawl and the arm is turned away from the abutment; but the turret-head is still moving in the same direction The result is that the arm next to the arm that has just mov'edfrom over the grooves 6 comes against the side of the abutment and turns it over toward the spring 2" sufliciently to let the arm come over the groove 6. The pieces I) are tipped down by the arm and the arm passes over them. As the motion of the turret-head is reversed and the arm holding the abutment to one side moves away from the abutment toward the die the spring forces the abutment back to its position. Such is the action of the parts mentioned when there are no paper tubes in the machine; but when the reciprocating turrethead-is near the die a paper tube is placed in one of the grooves e, and as the head comes toward the abutment an arm of the head enters the tube, and as the abutment prevents endwise movement of the tube the arm is forced into the tube. XVhen the tube, by the reciprocating and rotary movement of the head, passes through the rapidly-turning die, the die makes its outer surface hard, smooth, and glassy.

What I claim as new, and desire to secure by Letters Patent, is-

1. The turret-head II, provided with the arms 71., and having an intermittent rotary movement and a reciprocating movement cor responding to the movement of theslide, in

combination with the revolving die, as set.

2. The slide D and shaft G, arranged and turning in the slide, and carrying the ratchetwheel and turret-head, in combination with the pawl pivoted on a stud in the frame, asset forth.

3. The lever m, pivoted to the slide and carrying the roller 02, in combination with the inclined way 0, pin 9, and turret H, having a series of holes, Z Z, for the reception of said pin, as set forth.

4.. The combination, with the table A, slide D, and turret H, having means for holding the papertubes, of the feeding attachment A and abutment f, as set forth.

5. The combination of the table A, having beveled ways 0 O, the slide D, turret H, having arms 71. h, the rotary die It, the feeding attachment A, pivoted abutment f, having spring 4;, and mechanism for imparting a reciprocating and rotary movement to the turret, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
