ADJUSTABLE PUNCH-HOLDER.
Application led March 6, 1917. SerialNo. 152,485.
To all 'whom t may concern:
Be it known that I, ENocH KAvnNAGH, a subject of the King of Great Britam, and resident of Des Moines, Polk county, Iowa, have invented a new and useful Adjustable Punch-Holder, of which the following is -a specification.
The object of this invention is to provide an improved construction for a multiple punch holder, with means for selectively placing individual punches into operative and inoperative positions.
A; further object of this invention is to provide improved means for selectively adapting any desired number of a series of punches into position for operation, or into inoperative position, lto meet the requirements of a particular work in hand.
A further object of this invention is to provide a simple and easily operated device for adjusting to operative or inoperative position any of a series of punches in a multiple punch holder.
My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claim and illustrated by the accompanying drawing, in which- Figure 'l is an end elevation of a punch holder constructed according to my invention. Fig. 2 is a side elevation of the same, partly in section. Fig. 3 is a plan of a gag plate used with the device.
Fig. 4 is a bottom plan of another punch holder embodying my invention, illustrating the use of a'plurality of rows of punches. Fig. 5 is a plan of one form of gag plate which may be used with the same.
In the construction of the device as shown in Figs. 1, 2 and 3 the numeral l0rdesignates a head formed with an upwardly projecting shank 11r adapted to be secured in and to a punch press (not shown) in a common manner. A punch-holding plate 12 is removably and replaceably mounted in a longitudinal groove in the bottom of the head 10, and is held by bolts 13. The plate or block 12 is formed with a plurality of longitudinally spaced vertical bores in which punches 14 are removably and replaceably mounted, and adaptedfor vertical sliding movement at times. The plate or block 12 also is formed with longitudinal slots 15 intersecting the bores for the punches 14, said slots preferably being two in number and verti- Specication of Letters Patent.

cally spaced, whereby a sufficient bearing is provided for the punches but the frietional engagement thereof with the bores is materially reduced, and freedom of movement is obtained when desired. The punches 14 preferably are formed with Shanks of uniform diameter within the bores of the block 12, and with enlarged heads, the upper slot 15 of the block preferably openinrr to the top thereof and receiving said heads, which limit downward movement of the punches in the bores; but said punches may be formed with variously sized punching tips at their lower ends, to suit the needs of the particular work desired to be done.
The head 10 is formed with a longitudinally extending, end-opening aperture, reetangular in cross-section, above and in alinement with the heads of the punches 14, and one or another of a plurality of gag plates` 16, illustrated in Fig. 3 as an example of many forms which may be employed, is adapted to be slidingly mounted iu said aperture. Each gag plate 16 is formed with one or more circular holes 17 longitudinally spaced and of a diameter corresponding to or slightly larger than the diameter of the heads of the punches 14, and adapted to permit passage of said heads, and upward movement of the punches in their bores, when said plate is positioned with said holes in vertical alinement with the said punch heads. When a hole 17 of the gag plate is in registry with the head of a particular punch, that punch is thereby rendered inoperative, it bemg permitted to pass upwardly upon contact with the work when the head 10 descends in the operation of the machine. It is to be understood that the gag plate 16, to effect this result, 'must have a vertical dimension not less than the thickness of the piece to be punched; and I deem it preferable to employ a gag plate in any given machine of at least as great a vertical dimension as the thickness of any material to be punched thereon. When no hole 17 of the gag plate 16 is in registry with the head of a particular punch 14, but an imperforate portion of said plate is in contact with such head, that punch is thereby renseries may in this manner be employed at a given time, depending` upon the location and arrangement of the holes 17 of the gag plate employed, and upon the position of said plate in its seat. Y
To positively hold the plate 16 in adjusted position, I employ a spring 18 secured at one end as by a bar 19 and screw 2O togiven article, or in a large number of similar articles, without changing of punch holders or rehandling of the articles, by the use oi' this device. For example, assuming that the end punches 14 shown Vin Fig. 2 are three-eighths inch in diameter, and the central punch one-quarter inch, and that the centers of said punches are uniformly spaced one inch apart. Then, if it isdesired to punch an article, or a number of articles, with three spaced holes in one location y (con responding tc size and spacing of punches above described), and with two holes of three-eighths inch diameter and spaced two inches apart, in another location, and a single hole of one-quarter inch diameter in still another location, it is necessary for 'the operator simply to rst set his gag plate 16 (selected for such work) in such position that no hole '17 registers with any of the 40 heads of the punches 14 (or he may use an imperforate gag plate for such purpose); then by a sliding movement of the plate 16 he positions the plate so that" one of the holes 17 registers with the head of the cen- I tral punch, in the meantime shifting the operative. This saves handling and relian dling of the articles to be punched, and changing of the punch holders, and results in the saving of a large amount of time and labor.
In Fig. 4 I have shown'an example of a holder in which the plate or block 12a is of greater dimensions and equipped with a plurality of rows of bores for punches 14, and selection of which may be employed. A gag plate such as 16a is provided for each vrow or series of punches, and the operation is similar to that previously described, to elect the desired combinations'.
I claim as my invention- A punch holder formed with a plurality ofV bores and also formed with a groove intersecting said bores, punches removably and replaceably mountedin said bores, a plate slidably mounted in said groove and adapted to extend across said bores, said` plate being formed with a plurality of holesV adapted toV register selectively with said bores, whereby different combinations of said punches may be placed in inoperative position and the remaining punch or punches be placed in operative position, said plate being formed with a plurality of notches, and a spring4 normally bearing upon said plate, carried by said punch holder and adapted to be engaged selectively in one or another of said notches, whereby 'sliding movement of the plate positively is prevented.
Signedby me at Des Moines, Iowa, this second day of December, 1916.
