STENOILING DEVIGE.

Application iled April 14, 1982. Serial lo. 558,708.

To all 'whom it may comm.'

Be it known that I, JAMES H. RAND, a citizen of the United States of America, and resident of North Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Stenciling Devices, of which the following is a specification.

This invention relates to stenciling devices and more specifically to devices of this kind adapted to use the type of stencil sheet disclosed in my copending application, Serial No. 552,792 filed on April 14, 1922. but

many of the features of the invention are capable of general application.

Objects of the invention are to prevent creases, folds and undue strains upon the stencil sheet which tend to rupture it prematurely and to produce breaks therein which result in blotched and imperfect work, to provide feeding` means` for stenciling fluid which may be adjusted to the needs of the stencil sheet operated on, to provide a holder for the sheets of material to be stenciled which shall position each sheet in exactly the same position beneath the stencil sheet, and in general to improve devices of this kind to the end that they may be easier to operate and may render more satisfactory service.

For the purpose of illustrating the invention one concrete embodiment thereof is shown in the accompanying drawings, in which A Fig. 1 is a vertical longitudinal sectional view of the device on the line 1-1 of Fi 2;

Fig. 2 isa plan view with portions o the' pivoted frame broken away; F Fig. 3 is a section on the line 3--3 of ig- 2; j

Fig. 4 is a side elevation of the frame of the carriage in operative position;

Figd 5 is-a section on the line 5-5 of Fig. 4' an FFig. 6 is a section on the line 6-6 of e embodiment of the invention shown for the purpose of illustration comprises a base A, a stencil sheetsupporting frame B pivoted to the base and a carriage C mounted for longitudinal reciprocation upon the frame, the entire device being portable and adapted to be placed upon a convenient table or desk when in use. The frame B consists of side pieces 7, front end plate 8, and rear connecting plate 9 and has downwardly extending brackets 10 fast to side pieces 7 which are pivoted to brackets 11 on base A by means of a pivot pin 12. Brackets 10 have stops 10 for limiting the swin movement of frame B in one direction and are connected by an angle iron 13. Slidably mounted upon the upper web of angle 1ron 13 is a plate 14 disposed in the lane of plate 9 and having a downwar 'y bent front flange 15 through an opening in which extends screw 16 fast in the other web of angle member 13. Surrounding screw 16 and confined between angle iron 13 and ange 15 is a coil spring 17 which normall maintains plate 14 forward] disposed wit flange 15 against the hea of the screw. Upon the upper faces of plates 9 and 14 are spaced lugs 18 over which the reinforced ends of a stencil sheet D of the type described in my above mentioned co ending application are adapted to be hook sprin pressed plate 14 maintaining the stenci sheet under yielding tension.

Carriage C, which slides upon the side arms 7 of frame B, comprises a substantially rectangular structure having ends 2O and 21, sides 22, and a top 23, the forward portion of which is hinged to permit inspection of the interior, a projecting tab 24 being provided upon the .front of the hinged rtion for conveniently raising the same. idee 22 are provided adjacent the front end of the carriage with guides in the form of flanged portions 25 which are generall U-shaped or channel-sha ed, the upper and, lower portions 26 and 2v enclosing the side members 7 of the frame with considerable clearness as indicated -in Fi 5 for a purpose to be later described. ithin the carriage and mounted upon rods fast in the sides 22 of the carriage are rollers 28, 29, 30, 31. Roller 31 is containedin an ink reservoir 32 which is disposed at the front of the carriage and has a filling spoutr 33 extending outside thereof and provided with a stopper or other` closing means 34.- The pivot 35 for roller 31 extends outside the carri on both sides and its extremities are provi ed with ratchet wheels 36 keyed thereto. Mounted u n the projecting portions of pivot 35 but tween ratchets 36 and sides 22 are levers 37 having rollers 38 at one end, pawls 36 adjacent ratchets 36 and a rod 39 connecting the other ends of the two levers, the rod passing through aligned slots 40 in sides 22 of the carriage. Upon rod 39 is mounted for rotation another roller 40 which completes the train or series by which ink is transferred from reservoir 32 to roller 28. As indicated inF Fig. 1 roller 40 is slightly spaced from roller 31, but the heavy ink used brid es the gap between the two rollers. By ro ler 40 the ink is applied to roller 30 which is of felt and is adapted to be impregnated with ink. By the roller 30 the ink is applied to roller 29 which in turn distributes the ink to roller 28. The latter is the pressure roller for forcing the ink through stencil sheet D and is of rubber or rubber covered, rollers 31, 40 and 29 being of metal. For conveniently actuating the carriage rearwardly extending arms 45 are. provided connected by a handle 46.

While the cards or paper E to be stenciled may be placed directly upon the top of baselA, I prefer for convenience and speed in manipulating the device to provide a reciprocating slide holder 47 adapted to hold two cards. Slide 47 is in the form of an elongate rectangular plate as shown in Fig. 1, the edges of which tit in dovetail grooves 48 in guldes 49 and 50, fast to the top of base A in an suitable manner as by screws 51. Stops 4 on slide 47 are adapted to contact guides 49 and 50 to limit the movement of the slide. Since this device is intended to be used t0 produce cards for visible index devices it is desirable thatthe index material stenciled on the cards shall be accuratel located. For this purpose I provide gui e plates 52 on the sides of the slide 47 and a central partition plate 53 having undercut sides 54 to deine the compartments for the cards (Fig. 3). The cards are retained under these undercut sides by means of end plates or retainers 55, preferably spring pressed, having angular slots 56, through which attachment screws 57 pass to hold the plates upon slide 46. Plates 57 have an undercut face 58 corresponding to the under-cuts in partition member 53. A portion of the shelf above the undercut on plates 57 is bent u wardly to form projections 59 for readily orcing the lates 55 back when the stencil cards are to be removed and new cards are to be inserted. Side members 52 terminate short of the ends of slide 47 to permit the outward diagonal movement of end members 55. Any desired means may be provided for normally maintaining end members 55 at their inward limit of movement.

To manipulate slide 47 back and forth a lever 60 is provided pivoted at 61 in guide 49 which is receed as indicated at 62 to permit angular movement of the lever. The outer end of lever 60 receives in a slot 63 a pin or lug which is fast in partition member 53 and slide 47 and extends beneath the partition 53 and slide 47 as shown in Fig. 1.

In operation the user places cards of the lproper size in the spaces provided therefor upon slide 47. He then gras handle 46 and draws carriage C towar the rear of frame B holding the carriage C and frame B upwardly against its tendency to move downward as the heavy carriage moves beyond the pivot 12. When carriage C reaches the forward limit of its movement which may be determined by a suitable stop upon member 9 the user permits the frame B to swing down upon base A to dispose stencil sheet D over card E and roller 28 upon the stencil sheet. He then pushes the carriage forwardly with the parts in the position shown in Fig. 4, the roller 28 presslng upon a stencil sheet D and forcing the ink therethrough upon the card E on slide 47 As the carriage approaches the forward end of frame B cam members on sides 22 having rounded forward edges contact cam projection 66 upon the side members 7 and lift the carriage C upwardly to the position shown in Fig. 1 taking roller 28 off of stencil sheet D before the latter reaches the reinforcing end of the stencil sheet. This vertical movement of the carriage C relative to frame B is permitted the clearance between sides 7 and the parallel portions 26 and 27 of guide flanges 25.-

During the forward movement of carriage C r0llers'28, 29 and 30 have been rotated frictionally but roller 40 has been out of contact with roller 30 as shown-in Fig. 4. As carriage C approaches the limit of its movement rollers 38 on lever arms 37 roll upwardly upon adjustable cam members 70 which are pivoted in sides 7 and are adjusted by inserting a pin in suitable openings. T e swinging movement of levers 37 thus provided brings roller 40 into contact with roller -30 and moves pawls 36 rearwardly 'across the ratchet teeth on ratchet wheels 36 so that when the carria e is again moved forwardly and lever arm 3 is drawn to its normal position through the action of spring 72, roller 31 is rotated to bring the ink into contact with roller 40. Since roller 40 contacts felt roller 30 only when lever arms 37 are actuated by the contact of rollers 38 with cams 70, which occurs at the extreme rearward movement of the carriage, merely enough ink is applied to roller 30 to compensate for the amount applied by roller 28 to stencil sheet D on each reciprocation. Roller 40 is turned slightly at each contact with roller 30 by reason of its swinging movement into touching relation therewith. It is further turned by the movement of roller 31 transmitted to it through the ink which bridges the gap between the two rollers.

From the foregoin it is clear that one of the features of the invention is the unique arrangement by which the stencil sheet is supported at its ends only and maintained un er a yielding tension. vSince the roller 28 operates upon the sheet D from the fixed plate 9 toward the movable plate 14 no creases or folds are formed in the sheet. Furthermore by the provision of a stop means for the forward movement of the carriage and b y reason of the cam' rejection 66 which l1fts roller 28 from t e stencil sheet D at the proper time there are no uneven strains on the latter which would tend .to weakenit prematurelyand cause it to break.

Another important feature of the invention is the arrangement of feed rollers by which an adequate su ply of ink to the pressure roller is provided at all times, the adjustable cam member 70 permitting the supply to be regulated to meet the needs of each particular Stencil sheet used. The holder 4 7 with its accurately disposed straight edgesV and its stop members pos1- tions all the cards to be stenciled in exactl the same position relative to the stencll sheet so that a uniform stenciled product results whereby an even and attractive appearance of the index material is produced when the cards are mounted on the index panels.
