UNITED STATES PATENT OFFICE 00., OF'NEW YORK, N. Y., A CORPORATION OF NEW YORK ATTACHMENT TO EMBOSSING OR STAMPING MACHINE Application filed December 31, 1929. Serial No. 417,638.

My invention relates to a new and useful improvement in embossing or stamping devices. 1

One of the objects of my invention is to provide a simple and useful attachment, which can be used in connection with machines of the type shown in U. S. Patent No. 1,730,984 issued October 8th, 1929.

Another object of my invention is to proyide an embossing or stamping device which 'will permit the use of separate type members, and which will make it -possible to securely hold said separate type members in proper alignment, so as to secure stralght-line stamping.

Another object of my invention is to provide a device of this character with a universal clamping device which will make it possible to readily substitute type members in the device, so as to print or stamp markings of varying length.

Other objects of the invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above general statement of the objects of this invention is intended to generally explain the same without limiting it in any manner.

Fig. 1 is a top view showing the clamp in operative position.

Fig. 2 is a front elevation.

Fig. 3 is a sectional view along the line 33 of Fig. 2.

Fig. 4 is a view similar to Fig. 1, but show- 5 ing the clamp in the inoperative position.

Fig. 5 is a detail perspective view of the clamp.

It has heretofore been customary, in many classes of work, to print or stamp by means of separate type members. For example, this work is done upon leather goods when it is necessary to print or stamp the initials of the owner.

For many years it has been customary to clamp the aligned type members by means of a pair of jaws, which were moved towards each other, and away from each other, alonga line parallel to said type members. However, this clamping often resulted in slightly displacing the type members from proper proper alignment, it has been proposed to i use a supplemental clamp, which operated against a piece of metal which was pressed against the type members along a line perpendicular to the line of printing. However, unless this piece of metal had the exact size, it would not prevent the type members from being forced out of alignment by the pressure of the main clamping jaws.' Hence, it was necessary for the manufacturer to keep on hand a large number of these pieces of metal, and the substitution of one of these pieces of metal for another, considerably slowed up the operation of substituting one set of type members, for another set. This was particularly objectionable when initials were stamped on leather goods for example, be-

cause each set of initials is usually stamped on only one or a few leather receptacles.

According to my invention, a device of this type is provided with a universal third clamping member which can be readily manipulated or detached.

The device which is made of any suitable metal, such as brass, is provided with a base portion 1, side walls 2 and 2a, and a guide plate 3. The parts are connected by rivets or by any other suitable means. A pair of clamping jaws 4 and 4a, whose adjacent faces are planar, are caused to move towards each other, or away from each other, by means of the screw 5, which is mounted in suitable bearings in the members 2 and 2a. Said screw 5 is provided with knurled knobs 6 and 6a which are connected to the projecting ends of the screw 5 by means of collars 7 and 7a, held in position by clamping screws 8 and 8a. Hence, the screw 5 can freely turn, without any lateral shifting. The jaws 4 and 4a have oppositely threaded bores, with which the thread of the screw 5 cooperates, so that when the screw 5 is turned, the jaws 4 and 4a are given relative movement in opposite jaws 4 and 4a also make sliding contact witlr the wall 9, above and below the guide plate 3, so that said jaws are held in proper alignment at all times. In this particular embodiment, the members 2, 2a, 3 and 9 are integral with each other, but I do not wish to be limited to this integral construction. A plate 10 is connected to the member 1, and to the guide plate 3, by means of screws 11, and a spacin block 12 is provided so that the plate 10 is rmly clamped by the screws 11,. in

proper position.

A clamping screw 14, provided with a knurled head 15, passes through a suitably threaded openin in the member 10.

As shown in ig. 3'for example, the jaws 4 and 4a are provided with slots or recesses in which a clamping member 16 is slidably mounted. This clamping member 16 is provided with detachable screws 17 and 17a, which fit into correspondingly threaded openings in the ends of the clamping member 16. The clamping member 16 is freely slidable with respect to the jaws 4 and 4a, but the heads of the screws 17 and 17 a,are sufiiciently large to prevent the clamping member 16 from slipping out of position.

The operation of the device is as follows One or more type members T are placed in proper position against the wall 9. Either the knob 6 or the knob 6a is turned, to cause the jaws 4 and 4a to lightly clamp the type members T. The screw 14 is then manipulated, to force the clamping member 16, into the position shown in Fig. 1. Irrespective of the width of the line of type, the clamping member 16 acts immediately to hold the type members firmly, in proper aligned position. The screw 5 can then be turned to exert additional clamping force against the type members T.

If desired, the screw 14 can be first operated to force the member 16 into final clamping position, or into preliminary lightclamping osition, and this feature is of particular va ue when a long line of type is being assembled.

It is impossible for the type members to move out of proper alignment because the jaws 4 and 4a do not exert any force upon the clamping member 16.

In the embodiment herein described as the preferred embodiment of my invention,

both ends of the clamping member 16 project beyond the jaws which are adjacent to said ends. Likewise, the clamping member is movably mounted in the jaws. However, these details could be varied without departing from the invention. For example, if the clamping member 16 were movably mounted on any other part of the device, it would operate according to my invention as long as it could be moved in a direction perpendicumary clamping means for clampin the type members T by means of their end aces, andthat the member 16 together with the screw 14, constitutes additional clamping means adapted to clamp the lateral faces of the type members. It will be understood that this description only applies to the particular position in which the parts have been shown in the drawings, for sake of convenience, and that the invention is not limited to any particular position of the parts, shown and described herein. Likewise, it would not be departing from the invention if one of the jaws 4 or 4a were fixed.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.

I claim:

1. A device of the typespecified, having a wall against which a plurality of t 0 members are adapted to be clamped, mov gle jaws associated with said wall, means adapted to actuate said jaws to clamp the type members, an additional clamping member adapted to be forced against said type members in a direction erpendicular to said wall, at least one end 0% said additional .clamping member projecting beyond the adjacent jaw, and means adapted to actuate said additional clamping member, the end of saidadditional clamping member which projects beyond the adjacent jaw extending through an opening in said adjacent jaw.

2. A device of the type specified, having awall against which a plurality of type members are adapted to be clamped, primary clamping means adapted to clamp the end faces of the assembled type members, said primary clamping means comprising a pair of jaws, at least one of which is movable, and additional clamping means comprising an additional clamping member loosely mounted in openings of said jaws, and means adapted to urge said additional clamping means against the rear faces of the type members.

3. A device of the type specified, having a wall against which a plurality of type members are adapted to beclamped, a pair of relatively movable jaws adapted to clamp the end faces of the assembled type members, means adapted to produce a relative movement between said jaws in order to accomplish said clamping action, and additional clamping means comprising a bar slidably located in openings of said jaws, and

means adapted to urge said additional clamping member against the rear faces of said type members.
