IMPRESSING MACHINE.

Application tiled. February 21, 1913. Seria] No. 218,450.

To (zZ/Z whom t may concern:

Be it known that I, MARTIN O. Rnrinuss,

Philadelphia,

ing is a specification. One obj ect of my relatively simple,

Pennsylvania,

have invented of which the Jfollowinvention is to provide a substantial and conveniently operated machine for printing or making an impression upon a sales slip or similar paper the device being particularly adapted to allow of the easy insertion and removal Aoit the plate upon which is carried the type, lettering, etc., from which an impression is to be made.

A further object is to provide a machine of the above noted character in which the parts shall be so arranged and constructed that it shall Ibe conveniently portable and shall be especially designed to receive address vplates each projecting or formed eral plane.

It -is also desired to having side or edge flanges atan angle yto its genprovide a novel detail construction for the plate-carrying head and plunger with their associated parts, as well as Va novel and relatively simple device for automatically feeding the inlring ribbon un,-

der and in engagement with the plate from which an impression is 'to' be made.

The invention also vision of a device `for contemplates the propreventing the deposit of ink or coloring material Jfrom the ink ribbon upon the address plate,

which device includes a pair of spindles adjustably supporting a paper or other strip between said plate and ribbon.

These objects and other advantageous ends l secure as hei-ei natter set `forth, reference being had to the accompanying drawings, in. which 4ig. 1, is a sidc elevation ol an impressing device constructed according to my rvinvention,

Fig. 2, is a front chine shown in Fig". 1

Fig. 3, is a side elevation partly elevation of the main verti- Fig. 5, is a horizontal section on the line 5-5., 2, and

Fig. 6, is an inver carrying head.

ted plan of the plate- In the above drawings, ll represents a suitable supporting base having at its rear an upwardly and forwardly projecting standard which is vertically elongated under the front of said base yto provide a guideway for a plunger 3. The top of this front portion of the standard is forked for the reception of an operating lever /l and this is journaled on a spindle 5 extending between the branches of said fork. The upper end of the plunger is ,provided with a lrearwardly extending arm A6 whose upper face is designed to be-engaged by a cam-likev extension 7 from the rear of the lower end of the handle, while its under face is at all timles engaged by a coil spring 8 vmountedin a vertically extending recess of the standard 2. The lowerend of the plunger 3 has fixed 'to it by a pin 11 ahead 9 elongated from front to rear and whose under face has two parallel undercut grooves 10 extending also from trent to rear, for the reception of the turned over fianges -l of an address plate rllhis latter Lpreferably consists of an elongated piece of relatively stiii? sheet `metal having pressed out from it letters or symbols constituting, in the present case, a business address or residence, and it is 'free to slide longitudinally of the head 9 in order to pei'- mit of its convenient insertion and removal. The upper face of said plate is designed .to be immediately adjacent or in close contact with that portion ,ofthe under face of `the head 9 between the grooves-10.

The rear end of the head 9 is formed with two oppositely projecting lugs 12 to which is fixed a vtransversely extending bar 13 preferably by means of screws). The ends of this bar are turned up and. as shown in Fig. 5 have respectively iixed to them a pair of forwardly extending stationary spindles 11i whose front ends are threaded for the reception of thumb nuts 15. On each of Athese spindles is rotatably mounted a tube or sleeve 16y to whose rear end is ixed a ratchet wheel 17 ;-it being noted that each oit' said sleeves is longitudinally slotted in order that it may increase slightly in diameter when the thumb nut 15 is screwed upon its spindle so as to exert sufficient pressure upon its adjacent end. The Vnut and washer also serve to removably retain on the sleeve a reel 19 holding a portion oi the inking ribbon 2O which, as shown Fig. 2, is designed to extend from one of the reels across the under face of the head 9, over the plate iv and then to the second reel.

Respectively below the spindles 14 the bar 18 carries two other spindles 18 on which is wound a paper strip or web of fabric 18" extending fromy one of these auxiliary spindles, transversely across and in contact with the under surface of the address plate, to the second auxiliary spindle. Said paper strip is thus interposed between said plate and the upper surface of the ink ribbon 2O and, as its spindles are rotatable, it may be drawn across the head from time to time so that there will at all times be a clean surface adjacent the raised dress plate.

F or causing` the inlring ribbon 20 to be fed across the head 9, I mount a longitudinally slidable bar 21 in a suitably formed transversely extending recess in the standard 2, preferably to the rear of the recess for the spring 8, andto the ends of this bar I pivot two oppositely hung pawls 23l which, under the action of gravity, may rest upon the ktoothed edge ofthevratchet wheelsl? respectively; Said bar 21 is of such length that when either of its pawls is in engagement with the side of the standard, the pawl on its opposite end engages the .teeth of the adjacent ratchet wheel. i In order that the bar 21 with its pawls shall remain in a given position, I mount a set screw 24 in the standard in such position that it may be turned into holding engagement with said bar at will.

Tith the yabove described arrangement of parts, any desired one of a number of address plates is inserted in the grooves 10 of the head 9, and the sales slip, bill or other paper upon which it is desired to print or impress the address on said plateiis p laced under the head upon the flat upper face of the front portion of the base. If now the lever or handle 4 is swung back and down, its cam projection 7 engages the arm 6 of the plunger 3, forcing this latter down in i ts guidewayagainst the action of the spring 8 and ultimately causing the projecting raised portions of the address plate to print upon the sales slipthe ink ribbon20 and the paper strip 18"' being of course interposed. Thereafter, as the lever /1- is released, the spring 8 acts to raise the plunger 3 to its normal-elevated position and just before `the head 9 reaches its upper position, one

of the pawls 23 strikes the teethv of its ratchet 17, forcing this with the attached tube 16 and the reel 19 to turn through a part of one revolution. As a result a short I length of the ribbon 20 is wound upon this reel and a corresponding length is drawn from the other reelwhose movement is retarded to some extent by the friction exerted upon it by its tube 16, whose central portion portion of the ad-` has been slightly expanded for this purpose by setting up its -thumb nutl. A fresh portion of the ink ribbon is thus brought under the printing face of the address plate after each depression of the head 9, and thel consequent winding of said ribbon upon one of the reels is continued until it is practically `filled. The operator then loosens the set screw 24; and moves the bar 21 longitudinally in its recess until the second pawl 23 is brought into a position in which it will be engaged by its adjacent ratchet wheel. Since the teeth of the latter are disposed oppositely to those of the first ratchet wheel, the subsequent operation of the device will reverse the direction of the movement of the ribbon, causing it to be woundup on the second. reel.

Itis particularly to be noted that the address plate may be inserted or removed with the greatest ease and a succession of impressions made from any of a number of different plates without loss of time. means of the paper or fabric strip between the plate and the ink ribbon, the former isy kept clean and as said strip becomesworn or filled-'withl ink at any one point, it may be replaced by a fresh portion adjacent the address plate by turning one of the auxiliary spindles 18 to wind up a suitable length thereof. In order to insure that the ink ribbon and paper stripshall be substantially flat over the face of the address plate, I provide two parallel guide bars 22 respectively on opposite sides of the head 9. Said bars are shown as flat `elongated plates spaced away from thesides of said head and mounted with their lower edges slightly above a horizontal plane including the raised portions of the address plate. With this arrangement the ink ribbon and paper strip on one side of the machine pass from their spindles over the lower edge of one of the guide bars 22, thence across the face of the address plate, over the second guide bar and to their spindles on the opposite side of the machine.

Obviously the inking mechanism, consisting of the bars 13 and 21 with their attached parts, may be omitted without departing from my invention, in which case the docul ment operated on would be impressed by the address plate instead of printed.

I claim: i

l. The combination in an impressing ma! which an impression is to be made; a trans versely extending bar mounted on said head; two pairs of spindles mounted on the bar respectively on opposite sides of the head; a protective strip passing from a spindle on one side ofthe head, across said impressing` member to a second spindle on the opposite side of the head; and an ink ribbon extending between the two remaining spindles over said protective strip; with means for actuating the head to make an impression.

In witness whereof I aix my signature.

MARTIN O. REHFUSS.
