DAVID H. TALNOPER, OF NEW YORK, N. Y.
ADJUSTABLE DIE-HOLDER FOR PpNCH-PRESSES AND THE LIKE.
Application filed. August 4, 1913.
To all whom it may concern:
Be it known that 1, DAVID H. TALNOPER, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a certain new and useful Improvement in Adjustable DieHolders for Punch-Presses and the like, of which the following is a specification.
The invention relates to an improvement in machines for punching holes or for making buttons and has for its objects to produce a device by means of which the tool may be positively set in any desired position; to protect the operator from injury while operating the machine and to improve the efliciency of such machines.
These and further objects will more fully appear from an examination of the spec1- fication and accompanying drawings taken together or separately.
My invention is illustrated in the drawings in which the sameparts are designated by similar reference characters in all the figures and in which Figure l is a side elevation of a press equipped with my improvement.
Fig. 2 is a front elevation partly in section of the device.
Fig. 3 is a section on the line 33 of Fig. 2 showing a shell carrier in position, and
Fig. 4. is a section on'the line l of Fig.
I will describe my present invention as employed in a machine for covering buttons, but it is obvious that the device may be used in other analogous devices, such for instance, in substituting a punch and die for the button blank carrying devices illustrated.
In the embodiment illustrated the apparatus comprises a base or table 1, which may be supported on legs (not shown). The base is provided with a standard 2, which carries horizontal arms 3-3; carried on the arms is a head 4, in which is mounted a slidting block 5; which is provided with a stop 6, for limitingits downward movement.
Pivoted in the standard 2 is a lever 7 which has a treadle (not shown) at its lower end; said treadle being used to operate the machine in the usual manner. The upper end of the lever is provided with a head 8, which works in a socket 8' in the block 5.
An anvil 9 is permanently secured to the Specification of Letters Patent. Patented Feb. 19, 1918.
Serial No. 782,834.
base 1, and is provided with a sleeve 10 which is normally held up by a spring 11.
Carried by the block 5 is a mandrel 12, having a concave lower face 13. The mandrel is provided with a carrying sleeve 14, upon which is a rib or collar 15. A catch or link 16 is pivoted at 17 to the mandrel l2 and is provided with a notch 19 which engages the rib or collar 15 and retains the carrying sleeve in position on the mandrel. The link is provided with a cam face 20 for a purpose to be hereinafter described.
The upper end of the mandrel 12 is provided with a screw threaded extension 21 fitting a socket 23, in a bushing or extension 22, carried in a socket in the sliding block 5. The block 5 is provided with a set screw 26 which engages a groove 25 in the bushing in such a manner as to prevent it from falling from the socket and at the same time allowing it to turn therein.
A pin 27 is carried in the block 5 in such a manner that it is partly cut away to form partof the wall of the socket, and it is provided with a thumb nut 28 by means of which the pin may be drawn forward thereby securely clamping the bushing in place in the socket. Any other device, such as a set screw, may be used for this purpose. The bushing or extension is provided with a shoulder 24. which rests against the lower face of the sliding block and limits the distance the bushing may be inserted in the block and takes up the thrust.
A carrier for the lower part of the button is provided. This carrier, as shown in Figs. 2 and 3, comprises a thimble or nipple 29 which is provided at its top with a socket 33 for the reception of the shell. tuft piece 34: and filling piece 35. The thimble 29 is slidably mounted in a sleeve 30 and is normally held by friction in the upper part of the sleeve. A pin carried by the sleeve engages in a slot in the thimblo and prevents the latter from being withdrawn from the sleeve. The upper part of the sleeve 30 is curved and of such diameter as to be engaged by the end of the catch 16 when the latter is lowered. The carrier is adapted to be supported on the upper part of the sleeve 10 during a certain step in the manufacture of a button and is shown in position in Fig. 3.
In operation the catch or link 16 should always be on that side of the mandrel opposite theoperator so as to bezout of the way of the operators fingers when he is inserting the pieces to be operated on in position. This is made possible by'my invention. The mandrel is screwed into thebushing, the thumb nut 28 isloosened, the bushing and. mandrelaren Wturned until the catch or link is in 'its'proper position and thethumb nut is screwed up. The, parts are now .securely held in position and the machine is ready for operation; Y
My invention is particularly useful inmachines making buttons or the like of shapes other than circular, as the mandrel may be adjusted with the greatest nicety and the movable toolcan be always-brought into perfeCt a-linernent; with the lower 10116.
By; my invention bychanging the contour of the parts which carrythe elements which go -to make --up the button, buttons of square, oblong,;ellipti;cal, or oval shape niay,on ac count ofthe perfect adjustment of; the bushing, be made asreadily as circular ones.
."The operation of the device illustrated in Figs. 2 ,an ;1-3 is asfollowsz Ashell is placed top uppermoston the anvil. and a, disk of covering material is laid over it. The manr drel and carrying sleeve are now brought down, the sleeve 1,0:is depressed against the spring; 11; and the shell and covering are forced into the :carrying sleeve and held there by friction. ivThe mandrel is; now raised and the catch, byreason .of its engagement With the rib in, the carrying sleeve, carries the sleeve, and the covered shell with it.- 1 W 7 ;While the-above described operation has been going-011, the attendant has placed the collet carrying the tuft-piece and filling in the nipple 29;Wl'llCh is in vplace in the sleeve or {carrier 30. When. the bushing .and mandrel have reached the highest point of their 06 515521155 has; as be mate for travel the carrier is placed in position 'upon the anvil and rests in the socket'of the'sleeve 10, as shown in Fig. 3. The sliding block is again depressed. The cam on the catch Will engage the curved face of the carrier 30 and be moved-from" engagement With the rib 15. The carrying sleeve 14 will rest upon the carrier and the mandrel Will move tion,a mandrel carried by the bushing-said I mandrel cooperating with the anvil, a sleeve carried on the mandrel, a catch carried by the mandrel and supporting the sleeve, of means whereby the mandrelmay be adjusted to bring the catch in proper tive to the frame. of the press" 2. Ina press, 'the combination With an anvil and a mandrel cooperating therewith, a sleeve carried by the mandrel, j a catch-carried by the mandrel and supporting the sleeve, ofan extension or bushingoperatively supporting the mandrel, means for rotatably securing the extension or bushing to a movable part of the-press, and means for securing rotation. 7 1 v This specification signed-- and witnessed this 29th day of July, 1913. v r
