V The invention further contemplates the provision ofadjustable mechanism for causing the above-mentioned kind of: ribbon to be propelled in various lengths in each up -stroke of the ram ore row for makin the next or succeedi g im type" orst'arnpmay be arranged about the axis oftheram I U A The invention also contemplates a; simple ac j'us'table device,- which forms a portion of the ribbon propelling niechanism to be so adjusted as to cause the said propelling mechanism to propel a ribbon of the kind above-mentionedor it may be a typewriter ribbon,- forward in" each up St-rolieof the type carrying ram in anyue area length regardless of what horizonm anguafiguiar position the typemcmer car'rying the prssio'n, notwithstanding to what horizontal 2 lar' position the said type-holder may have been arranged about the axis of the ram. v The invention also contemplates the automatic operation of the above-mentioned ram by fluid pressure means as shown or electrically,- as, for instance,- by means of a solenoid, not shown.

The invention also contemplates the provisionoi an adjustable open or built-up frame sup; ported by a platform upon which to arrange the goods ormaterial tobe printed or stamped, and

for'adjustably Supporting a guide bywhich' to support a printing or stamping fluid pressure operated ramand its accompanying fluid cylinder. And further, the invention contemplates, as above-stated, the provision of an adjustable framework of open construction whereby that portion thereof which supports the ram guide and the said cylinder may be so adjusted as to increase or decrease the distance between the type-holder and the work to be printed or stamped. Also; the invention contemplates the provision of a ram which may be adapted to sup port a holder for holding an arrangement of type of stamps, and for supporting achase injwhich a printing form may be arranged. It also contemplates an open or built-up frame which is adapted to support at various stages; said ramand the type supported thereby to the extent that when stamping or embossing is being performed a uniform and even impression of the type or form is being made upon the work being supported by an adjustable platform supported by the said frame.

These and other features contemplated in the invention may be better understood by referring to the several illustrations in the accompanying drawings, and more fully described in the follow ing specification, and more particularly pointed out in the appended claims.

Illustrated in the accompanying drawings Figure 1 is a front view of the invention ensbodying the improvements a contained therein, and shows the type-holder carrying ram in its uppermost or inoperative position; g Figure 2 is a side or end view of Figure l, with certain portions of the ribbon feeding or" takea'ip' mechanism not being shown; 7 Figure 3 is a sectional view as seen from the plane ?'-3, of Figures land 2, but not showing the ribbon take-up rolls nor the ribbon -roll' arbor Figure 4' is afront view of a portion of the type-homer mechanism showing how the same may altered to support a chase in which 3 printing form may be arranged;

Figure 5 is a sectional view as seen from the plane 55, of Figure 4;

Figure 6 is an enlarged sectional view of the type-holder locking mechanism as seen from the plane 6-6, of Figure 2;

Figure '7 is a top plan view of Figures 1 and 2; and

Figure 8 is a sectional view taken on the plane 8-8, of Figure 2.

Throughout the several views similar characters refer to similar parts.

Essentially, the invention comprises an open or built-up adjustable frame in which is supported the printing and stamping mechanism. As illustrated in the accompanying drawings, the above-mentioned frame comprises a lower or base plate i8, and an upper plate H; the same being adjustably supported by uprights, l2 and 12. In turn plate H supports a guide i3, through which a type-holder carrying ram l4 operates. Being supported by said plate i l, by means of uprights l5, which are rigidly secured in plate I I, is a pneumatic or hydraulic cylinder 16, in which operates a piston H, to which is connected the upper end of type-holder carrier ram M. The cylinder I6 is provided with a cylinder head 9, at its upper end which is supported by uprights l5, and there securely fastened by means of nuts l9, as shown. And at the lower end of said cylinder is provided packing means for sealing piston rod H, as is shown at It, and 16'. Pipe connections are made in the wall of the cylinder, as at l8, and to the cylinder head [9, as at 20, through which pneumatic or hydraulic pressure may be forced against, either above, or beneath, the piston 11, to cause the same to operate downwardly or upwardly as may be necessary to cause the typeholder 2|, with whatever arrangement of type may be secured therein, to move to or from the work to be printed or stamped, or which has received the imprint or impression, as the case may Referring to Figures 1 and 2, it will be seen that the type-holder 2i is hingedly secured to a horizontally revoluble bracket 22, by means of hinge-pin 23. The bracket 22, in turn, is revolubly mounted on the lower end of ram l4, and supported by means of a screw-threaded shouldered rod 24, being securely fastened, as by means of a dowel 25, to the lower end I4 of ram I4. Referring particularly to Figure 2, it will be seen that bracket 22 may be rigidly secured, as by means of a knurled set-screw 26, in any desired horizontal angular position which, incidentally, also positions the type-holder to such position of horizontal angular adjustment.

The type-holder 2!, being, as above-stated,

hingedly mounted on pin 23, may be swung from its printing or stamping position, as is shown in Figure 2, to its type-loading position, as represented by light dotted lines 2 l and there locked in place by means of the locking mechanism, generally indicated by the reference character 26'. In the locking mechanism, locking pin 21 is adapted to lockingly engage holes, respectively, 28 and 29, depending whether the typeholder is in its printing or stamping position, or in its type loading position. Referring to Figure 1, will be seen type or stamp clamping jaws 30, which are slideably mounted on a jaw retaining bar 31, and a right and left hand screw-threaded jaw clamping screw 32. To each end of screw 32, is fastened, as by means of key pin 33, a screw-operating handle or knob 34.

Referring to Figures 4 and 5, it will be seen that the type-holder 2|, and the jaws for supporting a chase and represented by the reference character 33, are made suitably larger than'those, respectively, 2|, and 33, the jaws being cut out as shown at'3fl, to provide a ledge 35, upon which a chase may be supported.

Rigidly secured to the back of 22, as by means of screws 37, is a bracket 33, to which is mounted, at its left hand end, a flanged stud 38, upon which is mounted a spring-actuated friction disc 39, and a knurled screw-threaded nut 40, for backing up disc operating spring 4!. At the right hand end of bracket 36, is mounted for rotation a take-up or feed roller 42, and securely fastened to said roller is the smaller, 43, of two sprocket wheels. The larger sprocket wheel, 44, is revolubly mounted on a shaft 45, and is directly in line with said wheel 43. A sprocket chain 43 connects the said sprocket wheels to each other, the larger sprocket wheel 44 being the driver, and the smaller wheel 43 being driven by the larger wheel 44, through the medium of the sprocket chain 45. Also, revolubly mounted on shaft 45, is a ratchet wheel 41, to which is secured, by means of key pin 48, a rack or spur gear 4B. The sprocket wheel 44 is provided with a spring actuated pawl 49, hingedly mounted on a shouldered screw 50, the said pawl beingadapted to engage said ratchet wheel 41. The shaft 45 is securely fastened, by means of a set-screw 45', in a bracket 5| which is fastened, by means of screws 52, to bracket 55. Engaging said gear 48 is a gear rack 53, the bracket 5| providing a guide for the rack 53. The upper end 53' of rack 53 is driven into an externally screwthreaded sleeve 54, the two being pinned together by means of key-pin 55. Threaded over screwthreads 54', of sleeve '54, is a knurled sleeve 55, which is adapted to be adjusted upwardly, or downwardly, as the case may require, to vary the travel of rack 53, which is operably connected, by means of said chain 46, to the said ribbon feed or take-up roller 42. Beneath sleeve 56 is provided a lock-nut 57, by which to lock said sleeve 53 in its desired position of adjustment. Between nut 5'1 and bracket 51, and over rack 53, is disposed a compression spring 58, which is adapted to automatically maintain said rack and ribbon feeding mechanism in such position of adjustment as will cause the desired length or amount of ribbon to be propelled by the said feeding mechanism. As will be noted in Figure 3, ram guide i3 is provided with radial flanges, respectively, l3',.and l3. The upper flange I3 is secured to plate H, by bolts 9, but the lowe. flange [3" provides a stop for the rack adjusting mechanism, or sleeve 56, regardless of what hori zontal angular position the type-holder mechanism may have been adjusted to. The lower endof the rack is provided with a stop or limit pin 59. The ram I4 is also provided with a stop or limit pin 50, which assures the ram [4 of not going beyond its upward limit of stroke.

About equidistant from either side of the center-line of the machine (front view) are ribbon guides 6|, adjustably mounted on outstanding rods 62, which are fastened securely in slidingly mounted spring actuated rod supports 63, being inclinedly and adjustably mounted on bracket arms 36. The guides 6|, between which ribbon B may be guided, may be adjustably secured on rod 62, either by friction or a set-screw 64, as shown. g

Supports 63 are slidingly mounted between the face side of arms 36 and washers 35, which are held in place-by means of cotter pins 66, through and 69 tiilaiel-i are set at 39'': 1% post 69' is" see any of each of 'iip'poits- 63 B'S isatei'is'i sang I'll, "st 8 "meaning T9 tie: eiir'it of tensioii to' itialirf v desired tautriese oftlie above mention'ed ribbon wh'ili may be stretched across the face" or types o1 a am.

- Referring: to the" Severnviews; Figures 1, 2, a, anditwill be seen that the type-holder 2 l the top 21 and back 2t; of which, form aright angle with eachother. Andto the ends thereof is secured, as" by means of screws 1 l and dowels 12'. eli icl plates 13'.- And" to" the end lates 13' is fastened, as by means of screws 14* and dowels T5.- the clamping jaw support and guide 3|.

lit may be herestated} that heating units are generally provided for heating the type or stamp inthe holder in machines of the above descrip'' tion, but since it does not form a part ofthis invention any further mention isnot made.

The type 'lrolder 21 as previously stated; is hingedly' mounted on hinge-pin 28, which is fofcfl'il'ypressed into openings 23, in portions, respectively, 22 and 22" of bracket 22.

As previously stated, plate H and the mechanism supported thereby,- adiustably supported by the uprights l2 and I2.

The lower upright I2 is forcibly pressed into plate ID, at the four opposite-comers thereof and there flush-riveted into place" squarely with plate" 1'9". Furthenupright I2 is internally screwthread'd with screw threads l2", which correspond to screw threads l2-',- formed on the upright 12-. In this instance; upright I2 is prorided with an enlarged portion 16, which provides a'sho'ulder 16', upon which to support plate H; each" of the opposite corners of plate H, are provided identical circular openings I1. Til-rough each of said openings is extended a redue-ed circular portion 18; of upright l2. The said portion 18, revolubly, but closely, fits said opening IT, and is constructed slightly shorter than the thickness of plate ll. Extending up ffdi'n portion 18 is a short circular portion 19, over which is fitted a washer 88. And; extending up from said portion 19 is a reduced circular portion 8|, the same being of suitable diameter to snugly fit the bore provided ingear wheel 82,-- and to'come flush with the face- 82" of hub 82, of wheel 82. A keyway should be cut in extension 8|, to match the keyway provided in wheel 82, and a key 83 provided therefor. Between the face 82" and a washer 84, is placed a spring washer 85. Extending up from portion 8| is a screw-threaded portion 86, over which is threaded a nut 81, with which to draw the several parts, 16, I I, 89, 82, 83, and 84, in close frictional working relation to each other. Uprights [2 are each provided with a locknut 8, with which to lock uprights l2 and I2 securely together.

Each upright I2 is provided with wheel 82, and in mesh with each wheel 82 is a worm 88, which is fastened, as by a key pin 88, to a shaft 89, the same being journalled in bearings 98. And to corresponding ends of shafts 89 is fastened. as by a key pin 9|, a sprocket wheel 9 I, the same being connected to each other by means of a sprocket chain 92. To the opposite corresponding ends of shafts 89 is secured, by means of keypin 93, hand wheel 94, by means of which shafts 89 may be operated through the medium of this connecting sprocket chain 92. On desiring to raise or lower plate H and the imprinting and east the W1 [9* "sen sanespee sr p iinfirin and starlings astatiens ma ripen amass seine dfidt v tea to tettsrans to was res-see:

As will be seen by fefffing1t'r'1gur'e Figures 1 and 2, lever 21' is Iiingefdly inc nt'd bt'we'en' ears or legs 96; said-lugs; th holder; when arranged, or a chase havingaform d sposed therihi has been clamped; between respective jaws-,- the type holdef may again; by taking hold of lever 21', remove locking pin 21 from engage ment with hole 29. swing the type-holder to its former or imprinting. or stampingposition and there locked in place by allowing pin- 21; to again engage hole 28:

As wil-lbe seen: by referring to; sectional view; Figure 6; lever 21" engages pin 21, through a slot 21" formed therein. In order to be assured of pin 21 remaining in either of its locked positions in engagement with said holes 28 or 29, the same is held in said locked positions, until removed from engagement with said holes by means of said lever 21, by means of a spring 98, acting against a shouldered pin 99, which is mounted in a guide I00, secured, as by means of screw-threads I, threaded into a screw threaded hole I00", formed in that portion of the type-holder which supports lever 21. The said pin 99 is, in turn, secured to a piece 10 I, as by means of key pin l0l. which is, in turn, fastened to the upper end of pin 21, by means of a machine screw I02, as shown.

As previously stated, nut 56 may be adjusted upwardly or downwardly to provide a longer or shorter movement of rack 53, as the case may require, to cause the ribbon feeding or propelling mechanism to feed the ribbon in longer or shorter lengths as may be required. And, it may be necessary to adjust plate H, which carries the printing mechanism, upwardly, or downwardly, to bring the type to a position to suit the article upon which imprinting or stamping is to be done. As it may become necessary to adjust plate II, to cause it to be raised or lowered, it will only be necessary to revolve hand-wheel 94, in the direction to cause plate I l to be moved upwardly, or downwardly, as may be required to bring the type into proper relation with the article upon which imprinting or stamping is to be done.

It may be here stated too, that it has been found that imprinting and stamping machines having the type or chase holder carrying ram disposed at the end of an arm extending out from a vertical column an even and uniform impression will not result in view of the fact that when imprints or impressions are being made in such machines, there is the tendency of the outstanding arm to deflect from its normal horizontal position which results in an uneven and unsatisfactory imprint or impressionespecially when great pressures are required to make certain impressing and embossing operations. To obviate this unsatisfactory imprinting result the type or chase holder carrying ram is supported centrally between four uprights or corner posts forming a portion of the open framework described above. Also, as will be seen by referring to Figure 2, the top surface 21' of holder 21 is in engagement with the undersurface 22" of bracket 22, when the holder 2| is arranged in its locked imprinting or stamping position. Therefore, the holder being so arranged against the bracket 22 actually forms a joined continuation of the ram 14 together with bracket 22; therefore, any pressure exerted against the ram will be direct and uniformly distributed upon the type or stamp being arranged in the holder in view of the fact that the same are, substantially, uniformly arranged about the longitudinal center-line of the ram.

Having thus described the invention it may be readily understood that the minor details of its construction may be altered in several ways without departing from the spirit and scope of the invention, and without losing any of its attendant advantages. Therefore, what is claimed is desired to be secured by Letters Patent.

I claim:

1. In combination, a compressed fluid operated stamping and embossing machine embodying an upwardly and downwardly adjustable skeleton frame-work having a pressure controlled fluid operated motor centrally installed therein, and, horizontally revoluble imprinting and embossing devices holder operably controlled by the said motor, mechanism adapted to releasably lock said holder in a type or stamp loading position and in astamping position comprising a spring actuated locking pin operably controlled by a hand operated'lever, and ribbon foil carrying and operating mechanism carried by the said holder.

2. In combination, a compressed fluid operated stamping and embossing machine embodying an upwardly and downwardly adjustable skeleton frame-work having a, centrally disposed pressure controlled fluid operated stamp holder operating motor having a nonrevoluble reciprocable piston installed therein, a horizontally revoluble and hingedly mounted stamp holder having ribbon foil carrying and operating mechanism mounted thereon operably controlled by the action of said motor piston, and mechanism arranged to releasably lock said holder in a type or stamp loading position and in a stamping position comprising a spring actuated manually controlled locking device, substantially as described.
