(Cl. fill-28) l Claims.

This invention relates to type holders and especially those intended for holding metal type and adapted to be subjected to hammer blows to mark objects with the metal type.

Type holders for metal type have to be strong and rugged and provided with means enabling the type to be changed. They should be simply constructed and composed of few parts. It is also desirable that they be susceptible of manufacture at low cost.

The portion of the type holder against which the type bears and which transmits the force of the hammer blow through the holder to the type is called the anvil. The anvil should be of very hard heat treated steel to enable it to be used over a long period of time without becoming deformed by the type. Also the type should be easily and quickly removable and replaceable and means should be provided for holding the type properly in place in the holder when the device is in use.

I have devised a type holder having advantages in low cost of manufacture, simplicity of construction, ease of manipulation and foolproofness which I have not found in any other type holder heretofore available. I provide a type holder comprising a. body, a readily removable and replaceable anvil against which the type bears and a fastening device for fastening the anvil to the body. Preferably the body is laterally open, which not only facilitate-s removal and replacement of type but reduces the cost of machining in making the body. Desirably the anvil is insertable laterally into the body and means connected with the body and entering the anvil are provided for fastening the anvil in the body.

I further provide a type holder comprising a body, a combined anvil and type retainer against which the type bears and which holds the type in place in the body and means for fastening the combined anvil and type retainer to the body. Preferably the combined anvil and type retainer is insertable laterally into the body and desirably it has a portion lying alongside the type to hold the type in place. The combined anvil and type retainer preferably also closes the body.

The combined anvil and type retainer, herein generally referred to simply as the anvil, preferably has a portion extending alongside the type and a projection at said portion for interengagement with the type to hold the type in place. To enable removal and replacement of the type the anvil is shif-table to move the projection out of engagement with the type, this preferably being accomplished by tilting the anvil.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

In the accompanying drawings I have shown a present preferred embodiment of the invention, in which Figure 1 is a perspective view of a type holder with type held therein;

Figure 2 is a perspective View of the body of the type holder shown in Figure 1;

Figure 3 is a perspective view of the anvil;

Figure 4 is a perspective view of the body but in inverted position;

Figure 5 is a perspective view of the anvil but in inverted position;

Figure 6 is a view partly in elevation and partly in longitudinal cross section through the type holder showing type in place therein but with the anvil in it tilted or inoperative position providing for removal and replacement of the type; and

Figure 7 is a view similar to Figure 6 but showing the anvil fastened tightly in place to hold the type as in Figure 1.

Referring now more particularly to the drawings, the type holder comprises three parts, the body 2, the anvil 3 and the screw 4 for holding the anvil in place with respect to the body. The body is an elongated piece of metal of generally rectangular cross section provided at one end with a recess 5 which is open both laterally and longitudinally of the body. The recess is of uniform lateral depth, that is, in the direction perpendicular to the bottom 6 of the recess. A circular hole l whose axis is perpendicular to the bottom 6 of the recess extends through the wall of the body 2 and intersects the recess at its bottom. The internal diameter of the hole 1 is somewhat greater than the external diameter of the shank of the screw 4 to permit limited tilting of the screw as shown inFigure 6 and for a purpose presently to be described.

The anvil 3 is of a shape to close the recess 5 laterally, having a central portion 8 of a depth equal to the depth of the recess so that when the anvil is in place in the recess the inner surface of the portion 8 will lie flat against the bottom 6 of the recess as shown in Figure '7. The types are adapted to have their inner ends abutting against a shoulder 9 of the anvil, the anvil having an extension It extending beyond the shoulder 9, a projection ll projecting laterally from the inner face of the extension Ill. The projection II is adapted to enter recesses in the types to retain them in position in the holder when the screw '4 is tightened.

Referring to Figure '7, the types are shown. at

l5, each having a recess l2 adapted to receive the projection H of the anvil. The projection l I is smaller than the recesses l2 so that the thrust transmitted from the holder to the type when the device is used will be transmitted entirely through the shoulder 9 of the anvil and not through the projection I l. The anvil has a bearing of very substantial area against the inner end I3 of the recess 5. The screw 4 passes through the hole I in the base 2 with its head outside as shown in Figures 6 and 7 and is screwed into the anvil 8, which is provided with an internally threaded bore [4 for receiving the threaded shank of the screw. The shank of the screw is of a length equal to the thickness of the type holder as shown in Figure 7.

As will have become apparent from the above description, the anvil 3 is a combined anvil and type retainer as it serves to transmit the force of the hammer blow from the base 2 to the type and also serves to hold the type in place in the base. Thus the type holder is of extremely rugged and simple construction, consisting of only the three parts as described.

In Figure 7 the type holder is shown with the screw 4 tightened to hold the anvil firmly against the bottom 6 of the recess and to retain the types I5. When the types are to be changed the screw is turned out as shown in Figure 6 and the anvil is tilted until the projection H clears the recesses I2 in the types, whereupon the types may be withdrawn and other types substituted. The anvil may be very simply tilted after turning out of the screw 4 by pressure of the finger on the upper surface of the anvil adjacent the righthand end thereof viewing Figure 6.

The anvil is preferably made of high quality heat treated steel to withstand the impact of the types against the shoulder 9 when the device is in use. The anvil is small in comparison with the body of the holder so that the amount of metal in it is quite limited. The body 2 of the holder may be made of less expensive metal. Due to the substantial bearing area between the anvil and the base at the inner end l3 of therecess 5 the force transmitted between the anvil and the base when the device is in use is distributed through the metal of the base so that it is not necessary that the base be made of the very high quality steel preferably employed for the anvil. The employment of a single part acting as both anvil and type retainer contributes largely to the simplicity, ruggedness and foolproofness of the type holder. The parts are so designed that all of the machining operations are simple operations, resulting in low cost of manufacture.

While I have shown and described a present preferred embodiment of the invention, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously embodied within the scope of the following claims.

I claim:

1. A type holder comprising alaterally open body, a unitary anvil and type retainer against which type is adapted to bear and having means for interengagement with the type, the unitary anvil and type retainer closing the body and having a projection intermediate its ends bearing against the interior of the body opposite the lateral opening therein and about which the unitary anvil and type retainer is tiltable to move said means out of interengagement with the type to permit removal of the type, and meansv cooperating with the unitary anvil and type retainer and with the body to fasten the unitary anvil and type retainer rigidly to the body in type holding position,

2. A type holder comprising a body having a recess open both laterally and longitudinally of the body and of uniform lateral 'depth throughout, a unitary anvil and type retainer fitting into said recess and bearing against the body at the end of said recess, the unitary anvil and type retainer having a portion against which type is adapted to bear and a portion for interengagement with the type to hold it in place, the unitary anvil and type retainer having a portion spaced from its inner end bearing against the interior of the body opposite the lateral opening therein and having a recess at its inner end facing the interior of the body so that the unitary anvil and type retainer is tiltable about said last mentioned portion thereof to move said means out of interengagement with the type to permit removal of the type, and means for fastening the unitary anvil and type retainer to the body.

3. A type holder comprising a body having a recess open both laterally and longitudinally of the body, a unitary anvil and type retainer fitting into said recess and bearing against the body at the end of the recess, the unitary anvil and type retainer having a portion against which type is adapted to bear and a portion for interengagement with the type to hold it in place, the unitary anvil and type retainer having a projection spaced from its inner end bearing against the interior of the body opposite the lateral opening therein and about which the unitary anvil and type retainer is tiltable to move said means out of interengagement with the type to permit removal of the type, and means for fastening the unitary anvil and type retainer to the body.
