serial No. 852,324.

a type-bar forming and embossing machine, having a frame comprising a bed 11, which may be provided with supporting legs 12, the bed forming a support for two uprights 13 and 1-1, herein in the form of yokes having bearings 15 and 16, in which a driving shaft 17 is journaled. rThe latter may be driven in any appropriate manner, but herein a driving gear 18, secured thereto, meshes with a driving pinion 19, the latter belng secured to a shaft 20. 1f it is desired to operate the machine manually, the shafting 20 may be provided with a crank 21.

The strip of sheet steel or other Vappropriate material 22, from which the. type bars are to be formed, is herein supplied to the machine in the form of a roll placed in a reel 23, herein comprising a pair of side plates 21,1nounted to turn upon a spindle or shaft v rThis reel may be otherwise appropriately mounted, but herein its spindle or shaft is mounted .in a pair of supporting arms 26, and the latter are pivoted at 27 upon the frame, in order 'that the reel with its roll of material may be caused to act as its own brake, to prevent too rapid rotation, the roll of material for this purpose resting directly upon a guide 28 for the strip.

As a means for guiding the strip and holding the same against lateral displacement, the guide 28- (see Fig. 2) is provided with a groove or channel 29, whose width corresponds exactly wit-h that of the strip, a lowing a` slight clearance to permit the same to slide freely.

rThe strip of material may be fed by any a other appropriate means, but herein I have provided feed mechanism comprising a feed slide 30, mounted to reciprocate in appropriate guidewaysl 31. rlhis' feed slide herein carries a strip-engaging member, herein in the form of a feed pawl 32. This feed pawl might engage the strip in some other appropriate manner, to impart an intermittent feed movement thereto, but herein the.

whose rear face or edge is inclined forwardly somewhat, as shown in Fig. 1, whereby it will be` readily' withdrawn simply by this rearward motion. The pawl may be held in engagement with the strip by gravity alone if desired, but I prefer to employ a spring 35, to assist gravity 1n maintaining such engagement. The feed slide 30 herein receives its reciprocatory moven'ient from a cam 36, to which it is connected by a link 3T and lever 38, the latter carrying a cam roll 39, engaging the cam, which preferably has a closed cam path or groove 40. The lever 38 is herein'fulcrumed at 41 on a bracket 42, supported 0n the bed 1l. lThe stroke which the cam mechanism imparts to the feed slide is equal to, or slightly greater than the distance Lbetween two adjacent perforations of the strip, so that at each for vard stroke, the latter is fed forward a distance equal to the space between two perforations.

As a means for avoiding accident to the feed mechanism, in the event of accidental stoppage of the feed strip by some obstruction or accident, I have herein provided a cam mechanism with a safety device comprising a spring 43, carried by the cam lever 3S, and engaging a pin 44, carried by the link 3T, the strength of the spring and the arrangement of the parts being such that, in the normal operation of the machine, the spring is unyielding. and the full working stroke is imparted to the feed slide. If, however, there should be any abnormal resistance to the feeding movement of the strip, the spring' will yield and allow the slide to stop. while the cam lever continuesr its forward movement. The spring 43 may be. of any other appropriate form, and otherwise mounted upon the cam lever, but herein is fixedly secured at one end to the lever by a screw 45. and is provided with means of adjustment consisting of a screw 4G. passing through the spring and threaded into the lever. whereby the free end of the spring may be caused to bear with a greater or less degree of pressure against the pin 44.

I will now describe the character-applying, impressing, stamping or embossing mechanism` by means of which the printing characters are raised or embossed, or otherwise applied to or impressed upon the strip, by the use of coperating pairs of` dies, which are so arranged that any predetermined character or group of characters may be brought at will to an operating point in alinement with the strip, and simultaneously caused to impress such character. or

group of characters, thereon.

The character stamping or embosslng mechanlsm may be of other appropriate construction, but herein comprises a guide block 47, havinga guideway for the strip, consisting of a. groove 48 (see Fig. 4), whose side walls are spaced apart sufficiently to guide the strip and provide a working clearance to allow the same to be moved freely in a longitudinal direction. The block 4T is herein provided with a recess 49, extending lengthwise of the same (see Figs. 4 and' 5), to receive a series of bars 50, slidably mounted therein and provided respectively with recesses 5l, containing bars 52, respectively, interengaging with the bars 5() in such a manner as to be, movable longitudinally in unison therewith, and yet capable of relative vertical movement (see Fig. 4). To this end, each bar 52 ismade the same length as its respective recess 51, with a proper working clearance, so as to be capable of moving freely in the vertical direct-ion, but held against lengthwise movement with respect to the bar 50 by which it is carried. y

rIhe bars 50 may be, and preferably are, provided with handles 53, which may be grasped to facilitate the longitudinal shifting of the bars, and these handles are preferably spread apart at their upper ends (see ig. '5), to enable eachpart to be readily grasped without interfering with the others. `Each pair of bars 50 and 52 constitutes the members of a pair of dies for embossing the raised characters upon the strip of material to form printing characters. If the characters are to be numerals, each pair of dies will be provided with mating numerals l to 9, inclusive, and 0, and correspondingly, if letters of the alphabet are to be embossed, the coperating die members will be provided with mating letters. In the specific instance shown, four of the tive pairs of dies will be provided with numerals and the remaining one with letters, in order that a type bar may be formed with any desired letter of the alphabet, associated with any numeral or group of numerals up to and including a fourgure number. The number of pairs of dies may,`of course, be increased without departing from the .spirit or scope of the invention. Herein, the upper dies 52 are provided with raised characters 54, andthe dies 50 with depressed characters 55, as shown in'a conventional manner in Fig. 10, although it will be evident that the dies may be reversed if desired. l

As a means for holding the dies normally in spaced relation, so that the strip may 'be fed between them without interference, any appropriate means may be utilized for lifting the upper set of dies, but herein eac-h I caused to coperate to press or emboss in 1'30 68, constituting guides `in the form of tongues 69, formed Leaders the strip of material any predetermined they will rise by permitting the stiip to be` fed.

As a means for holding the various pairs of dies in the selected position of adjustment, each bar l50 is herein provided with a series of notches 57, cooperating with a spring 58, which serves as a detent normally holding the slide against lengthwise movement, but permitting such movement upon application of a suliicient amount of force'to cause the spring to be forced out of the notch in which it is located. The spacing of the notches will, of course, correspond and be equal to the spacing between the characters upon the dies, there being one notch for each character or pair of characters, so that any selected character or pair of characters may be brought to the working point, and held there during the embossing operation. The springs 58 may be of any other appropriate type, but herein all o them are formed of a single plate (see `Fig. 6), having a raised portion 59 provided with a series of slots 60, dividing the saine into separate resilient portions, in effect a Separate spring, but having their ends united by flanges 61-61. The springs may be otherwise appropriately mounted in theblock 48, but herein the latter is provided with a recess 62, in which the spring is held by an inserted block 63. As a means for indicating to the character or group of characters at the embossing point at any instant, l have herein provided an indicator comprising a plate 64, having therein a sight aperture 65, through which lthe operator may view a character or group of characters impressedupoii the bars 50 (see Fig. 5) ,the arrangement of these characters corresponding exactly with the characters on the embossing dies already described. Thus, if the character A alone appears at the aperture, the operator is apprised that the impression taken Aat that moment will cause the letter A to be impressed upon the strip;

Any other appropriate impression mechanism may be utilized, but herein an impression slide 66, having an inserted hardened block 67 is arranged to depress all of the bars 52 simultaneously, to cause the dies to impress or einboss upon the strip of sheet materialv at will a predetermined group of printing characters. The impression slide 66 is herein provided with a pair of grooves guideways for a pair yof on or appropriately secured to housings 70, the latter being attached to the sides of the yokes 1 3 and 111 (see Figs. 1 and 4).,

rlhe impression slide 66-may be reciprocated vertically by any appropriate means,

tuting a guideway, each constituting the operator` but herein is connected by an eccentric rod and strap 71 to an eccentric 72, the latter being secured to the driving shaft 17. The eccentric rod may be provided with means of adjustment, herein comprising a rightand left-threaded screw 73, provided with lock-nuts 74 and 75. By this means, the eccentric iod may be lengthened or shortened at will, thereby to vary the strength of the impression.

As a means for severing'the strip of material at intervals, l may employ any suitable cutting mechanism as, for example, that which is illustrated, and which comprises upper and lower cutters 76 and 77, the latter being preferably provided with an inclined face 78, the purpose of which will presently appear. The upper cutter 76 is herein secured toa cutter slide 79, provided with a recess 80, which receives the cutter, the latter being secured to the slide 4by one or more screws 81. As a means for preventing the upper lcutter slide from lifting the strip after a piece has been severed therefrom, l have herein provided a guide block 82, having a groove 83 constiin which the strip of material is held by overlying plates 84 (see Fig. 3), herein secured to the guide block by screws 85. y

rlhe cutter' slide may be reciprocated vertically by any suitable mechanism, such for example as an eccentric rod and strap 86, and an eccentric 87, the latter being-secured to the driving shaft 17. The eccentric rod may, if desired, be provided with means of adjustment, herein comprising a rightand left-threaded screw 88 having lock-nuts 89, by means of which the cutter slide may be adjusted, so that the upper cutter will properly coperate with the ,lower cutter. The `eccentric 87 is set so 'that the cutter slide is properly timed to cause the strip to be severed contemporaneously with the embossing operation, and both occur in the interval between the feeding operations.

After the strip has been embossed and severed, as already described, the severed piece is next formed with two lateral flanges projecting in a direction opposite to that of the raised characters,vand the completed type bar is then ejected from 'the machine. rlliis may be accomplished by other appropriate means, but herein the piece, after being severed from the strip, is advanced slightly by the action of the inclined surface 7 8, already referred to, until the forward end of the piece strikes an abutment 90, which limits its forward movement, 'and it then drops upon two ledges 91, which support it in readiness for the next operation. rl`hese ledges, it will be observed by reference to' Fig. 7, are separated by a space 92, which corresponds to the width the completed type bar is to have. These ledges are appropriately formed on, or secured to, a pair of, guide lugs 93, separated by a space 91 very slightly greater than the Width of the severed piece of the strip, so that the same is accurately held against lateral displacement. A forming block, or plunger, 95 non7 descends upon the piece, and forces the same through the opening 92, the thickness of the block or plunger being approximately equal to the Width of the space 92 minus twice the thickness of the strip, so that as the block passes through the opening and forces the piece therethrough, right-angle flanges 96 are formed, and a completed type bar 97 is ejected through the bottom of an outlet opening 98.

The plunger or forming block 95 may be actuated by any suitable mechanism, as for example a vertically reciprocating slide 99, y

operated by an eccentric rod and strap 100 and eccentric 101. The eccentric rod may be provided With means of adjustment, herein comprising a right and left-threaded screw 102, (see F ig. 1).

rllhe operation of thev forming block is preferablyv so timed that it strikes the piece the instant after it has been severed, so that the operation of forming, cutting and ejecting the piece take place in quick succession, and in fact constitute one continuous operation. It Will now be apparent that one completed type bar is formed with each two succeeding impressions of the ma china-that is to say, While one set of characters is being impressed upon the strip at one point, a previously embossed portion is being severed, formed and ejected.

1t will be observed that the article produced in this particular instance is a type bar provided With longitudinal flanges and a perforation, and having one or more raised reversed printing characters. 1t. will be remembered that the perforations, or their equivalent, Were formed in the strip previous to theintroduction of the latter into the machine. There is a particular coaction between the feeding device and the particular form of stock used.

lilach completed type bar isV provided with a perforation, which may be utilized to receive a pin or similar opposing element, for

the purpose of' longitudinally positioning and securing the type bar, While the longi! tudinal anges may be utilized in the transverse positioning of the type -bar in the printing machine in which the type bar is intended subsequently to be employed. The flanges also possess the advantage of providing a reinforcement giving rigidity to the type bar, and preventing injury thereto because of distortion. j

While l have herein shown and described one specific embodiment of my invention for illustrative purposes, and have disclosed provided With check nuts 103 and discussed in detail the construction and arrangement incidental to one specific appli cation thereof, it is to be understood that the invention is limited neither to the mere details or relative arrangement of' parts, nor to its specific embodiment herein shown. but that extensive deviations may be made from the illustrated form or embodiment of the invention, Without departing from the principles thereof.
