7 To all whom it mag concern The present invention relates to steel type v holders and the main objectof the invention 5 is to provide a holder of this character that.

will permit an easy exchange of types and yet secure the steel types very firmly in the holders during the stamping process.

By means of these holders it is possible to make good impressions upon hard metal or wood surfaces with thecharacters in per- 'fect alinement and uniform depth "on the article to be stamped.

" 'Holders of this character, in which the types are assembled andretained by use of a single set screw pressing all'the types to wards one side of the cavity in which they are held are well known. It is evident that no individual setting of a steel type is possible in such holders as they are all dependent on the single set screw.-

In the present invention each steel type is provided with a separate set screw and it can accordingly be adjusted independent of the rest of the types contained in the holders,

the latter accommodating two to twenty types or more. For this reason the holders forming the subject matter of the present invention are 7 provided with. a series of threaded apertures on the front face of the holder, in which apertures the set screws are engaged so as to secure each steel type or possibly two when the. types are'small.

It is evident that by means of this ar rangement timers gained when 1t is necessary to 'excha'ngethetype, as for instance, if

articles are to be numbered inconsecutive order, the unitordinal would have 'to'be exchanged between each stamping and 'accordf in-gly only one of the set screws would bemoved to replace the unit ordinal, whereas in the other form of type" holders toe entire line of type contained in the holder would be disturbed and there is danger that the-whole, line might fall out of the'holder.

Another advantage'of the constructionof the present holder is that the set screws when clamping the types are all flush with the front face of the holder, so that all injuries to the users hands are avoi'ded,there belng' no projecting parts on theh'older'durlug-operation. i i

" In the accompanying;drawing one eI'nj bodimcnt of the invention is illustrated, and;

Figure 1 representsaperspective view of the holder with the line of-steel types in position; i

Figure 2 is a transverse section along line 2-2-of F1gure1;k

Figure 3 is a longitudinal section alongline 3 3 of Figure2;

-Figure 4 is a section similar to Figure 2 of aslightly modified form'of the holder suitable for smaller'type; Figure 5 is a perspective view of a tit wrench suitable for tightening the set screws in the type holder; and V I Figure 6 1s a section SIHIllBI'tO Figures 2 iande showing the arrangement o'f the typesin a two line holder.

The holder consists of a handle portion 10 of preferably square, round or hexagonal cross section with a slightly tapered hardened endll against which the hammer blows are applied, when the deviceg is in use; The head '12 of the holder is preferably of the same thickness as'the handle 10, but

widened out inaccordance with the number of types it is intended to carry. The

end of the head 12is provided with a recess 13 of sufficient depth tol comfortably and; securely seatthe steel types 14. The

steel type is preferably of rectangular-cross,

section and each provided with a milled *nOtch or "groove 15 running transve'rsely across its shank The width of 'the recess agrees closely with the height iof the type, and the depth of the recess is about two thirds of the length of the'type, tr-

minating with the flat bottom against which the type is firmly seated, asseenin Fig- The recess l3 preferably produced by drilling two parallel holes, onenear each} siderof the head 12, to the-depth required. f ff by the recess and then milling out the intermediary material; The rounded-"ends" l6 of the recess are thereupon filledbyjmeans '7 of the half round"filling pieces 17, which may be provided with short '-sha nks* 18 tapped or riveted forrigidly securing the same in the recess, or the half round fillingl pieces 16 maybe welded in the head 1 2 be equal to the added thickness of the types 'to be carried in the holder, in Figure 2,

four being shown. It is evident that any other number. may be seated in the recess and that the length thereof in such a case has to be modified.

At a uniform distance from the end surface 22 of the head 12 are provided threaded openings 20 adapted to receive set screws These openings 20 are positioned so that, when the set screws 21 are tightened against the types, the inner ends of the screws will engage in the respective notches or grooves 15 in the steel types. These set screws are preferably of the socket head kind, adapted to receive a tit wrench and of'such a length that when they are turned up tightly against the types 14 and engage in the grooves or notches 15, no part thereof will project beyond the front face 23 of the head 12, as clearly seen in Figures 2 and 3.

A convenient form of tit wrench is shown in Figure 5. This wrench '24, may be manufactured of suitable wire and bent into E..- shape, with a short shank 2-5 and a long shank 26, the ends of which are milled as at 27 and 28 to fit the socket heads of the set screws 21. To tighten or loosen the Screws, the short shank 25 is inserted in the socket head of the screws using the long shank 26, as a lever, while to unscrew the said screws, after loosening them or to quickly screw down the same, the end of the long shank is entered in the socket head of the screws using the short shank 25 as a lever. V

F or smaller type holders, the construction indicated in Figure 4 is preferable, in which each set screw 29 is adapted to tighten two of the types 30 in the recess of the head 31. In this case, the notches or grooves across the shanks of the types '30 maybe entirely omitted. The small holder is otherwise of similar 'constructionto what has been described in connection with Figures 1, 2 and-3,.and the set screws are also in this case turned up to be flush with the front face of the holder or to come slightly below the same. Half round filler pieces 33 are also used in the smaller holder, and se cured by means of rivets 32 or the like.

The type holder may be manufactured from square, round or rectangular steel blanks, one end of which is upset to form a flat'broad head 12, asiseen' in Figure 1'. In this manner the'front and rear faces of the holder form fiat plain surfaces, while the sides of the head project in both directions from the handle 10. After the type holder has been forged into this shape, it

These holders may also be used in punch presses of machines or any other kinds 0 or shank 10 takes the section of the socket in this Press or machine.

In some cases it is desirable to make two line marking on metal or wood and in that case two line holders are provided as i? licated in Figure 6. In that case two parallel recesses 40 and 41 arefurnished in the holder, each having separate clamp or set screws 21 arranged on opposite sides of the holder, as indicated in this figure. The construction is otherwise identical to that for the single line holders. in the two line holders different sized types may be used in the recesses, for which reason the latter are made of different width. These recesses are also machined in the same manner as already. described, having half It is evident that cess, said'rneans comprising socket-head set screws, suitable apertures for said set screws being provided in said head between the recess and the front face thereof and said set screws having their outer ends flush with the front face of the head when in position to secure the types.
