SPECIFICATION forming part of Letters Application filed August 28,1889.

To all whom, it may concern.-

Be it known that I, ANSEL G. BAKER, of New Bedford, inthecounty of Bristol and State of Massachusetts, have invented a new and useful Oharactering-Machine, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a plan of a machine embodying my invention; Fig. 2, a side elevation of the same; Fig. 3, avertical section on line 3 3 of Fig. 1. Fig. 4 is a plan view of a female dieplate. Fig. 5 is a plan of the machine with parts'removed to show mechanism within the tubular support for the impression-bar carrier- Fig. 6 is an elevatiornpartly in section, on line 6 6 of Fig. 5.

The chief object of my invention is to produce an improved machine for use in putting characters on sheet material, as by punching, embossing, or printing the desired charactersr The machine in which my invention is here shown embodied is a machine adapted to punch characters in bank-checks, certificates of stock, and the like.

My invention may, however, be embodied in machines for various other uses, as will be plain to all skilled in the art.

My invention consists, chiefly,in a positive work-feed and guide-rolls combined together to accurately feed and guide the work under the impression-bars, and in a rotary support carrying a series of impression-bars combined with a single key and a guide-frame, which causes the key to register accurately with the impression-bars.

Other features of my invention will be set forth hereinafter.

In the drawings, in which I show my invention embodied in one of several forms which I have contemplated, but which is, on the whole, the best form now known to me, A is the base; B, one form of work-feed; D, a carrier for the impression-bars, and F a key to operate the impression-bars mounted in the carrier. Hitherto machines of this class Patent No. 425,725, dated April 15, 1890.

tween the characters. In order to obviate this objection, Iprovide a positive feed, which is conveniently formed of an oscillating bar B, roughened at its outer end and projecting against the work through the opening a in the work-support a. The feed is connected to the key F in such wise that the work is fed by the movement of the key, depression of key F in this form of my machine carrying the feed 13 out of contact with the work, and the opposite motion of the key causing the feed to operate. The positive feed B and key F are conveniently connected by rockerarm 1), fast on rocker-shaft I), mounted in a bracket on base A, rocker-arm b fast on rocker-shaft b, lever 19 connected to spindle 1), playing in the hollow shaft 9 of carrier D, and lever 5 connecting spindle b to key F. When key F is moved away from the impression-bars, the spindle b is moved inwardly and feed F actuated to feed the work. The feed is moved back to its inoperative position, say, by means of a weight, a weight be ing, I think, much better than a spring for this purpose, because the weight acts more rapidly and positively, as will be understoodby all skilled in the art. The presser-foot A holds the work on the work-support and supports rolls a, which guide the work and keep it straight as it is fed along by the feed B. Presser-foot A is best formed with a sighthole 3 and a thumb-piece a and rocks on pin a, a spring a being used to keep it in place on the work.

Key F is mounted in a stationary bracket f and is caused to accurately register with an impression-bar by guide-frame F, which is best formed, as shown, with slots f, in which projection f on the key plays when the key moves. The ends of the impression-bars d, in this form of my machine, project through openings f in frame F, and are sustained by springs cl, mounted in the bar-containing chambers d in the carrier D. Bars (Z, if formed with rounded shanks, as shown, are best provided with projections d playing in recesses d in the walls of the containingchambers (1 The impression-bars, of course, are provided with charactersin this case, male dies. \Vhen male dies are used, the female die-plate D is desirable. The guide as explained above.

frame F in the present construction bears characters corresponding to the characters on the impression-bars, and the carrier D, female die-plate D and guide-frame F rotate together between the key and sight-hole in the presser-foot. When the desired impressionbar is brought into place to give its impression, the key is depressed, and while it is engaged with the slots in the guide-frame the key and impression-bar are kept in fixed relation to each other, so that depression of the key causes the impression-bar to move against the work-4n this case through the sight-hole s. The keycannot enter a slot in the guideframe until an impression-bar is over the impression-point-, (or, in the present construction, in which the presser-foot is formed with a sight-hole 8,) is over the sight-hole, because the key is mounted in the fixed bracket, Which has a fixed relation to the impression-point, The ears formed bythe slots in the guide-frame are best rounded off, so that the key when depressed will the more readily enter the slot. This combination of the guide-frame with the impression-bars and the key mounted in a bracket having a fixed relation to the impression-point is an important feature of my invention.

Another important feature of my invention is the combination of the feed and key through the hollow shaft of the carrier, because it results in compactness and simplicity of construction. Of course other than the positive feed shown may be. employed in this combination without departing from the spirit of this feature of my invention, which is to combine with any sort of feed a single key and rotary impression-bar carrier, the ,key

and feed being connected through the hollow ANSEL G. BAKER. \Vitnesses:
