Application filed, November 4, 1921. Serial No. 512,707.

To all whom may concern.'

lle it lmown that I, (irnosy E. Mon-nnoosn, a citizen 'oit the United States, and a res-ident ot Philadelphia, the. county ci' Philadelphia and State ot Pennsylvania, have invented an Improvement in Stencil-Moistening Devices, oit which the following is a speciiication.

My invent-ion relates to. devices for mois toning. stencils preparatory to the tormin'g thereon or' markings such as letters, tigrrres, etc., and it has 'for its general object to prof vide a device having means for simultaneously moistening both sides of the central tibrous sheet of' the stenci'lon which the markings are. to be placed?.

A further objectis to providey a device. having a moistening means and means for. successively supplying stencil-l cards thereto to be moistened..

Another obj ect is to: provide a device comprising a couple of oppositely disposed co operating m-oisteni'ng pads with means for successively removing sten-cils from a pile and convey-ing them into position between said pads where they. become moistened.

A still further object is to provide. means whereby one ot the said pads may be reciprocated and also means toy effect relative movements oi the said pads away from each other prior. to such reciprocating movement so as to prevent sliding movement of either pad against the stencil card.

@ther objects and advantages oli the invention will be point-ed ont i-n the detailed description thereori? which follows or will he apparent from such description.v

ln order that the invention may be readily understood and its many practical advantages "lull-y appreciated, reference should: be had to the accompanying drawings in which l have illustrated one forni of a convenient embodiment there-'oi'. However, it will be understood that the invention is susceptible oi' embodiment in other forms oi construction than that shown and that changes in the details of construction may be made within the scope ott the claii'ns without departing from the invention.

ln the drawings:

Fig. 1 is a view inl side elevation ot a de vice embodying my invention Fig. 2- is a top plan view thereof;

l? 3 is a longitudinal central sectional view showing the parts in normal position ready to be operated;

Fig. 4 is a similar view but showing one ot the parts` after it has been operated and in eXGnded position;

Fig. 5 is a transverse sectional view taken on the; line 5,-5 of Fig. 3;

lig. 6 is a top plan view of a portion oft the structure. with certain other parts reigt 7; is a top, plan view of one of the stencil cards;

Fig. 8 is a view in side elevation of a modified construction ot one member ot the moistening means Eig. 9 is a transverse` sectional view taken on they line 9 9 of Fig.A 8 and 1() is a longitudinal sectional view tak-en on the. line. 10,-10. of Fig.. 9, the porous pad sheet or cover being omitted.

Referring-to the drawings: 1 designates a rectangular shaped receptacle which is adapted to hold water, as indicated at 2. TheA said receptacle is provided at its opposite sides with guides, as indicated at 3, the said guides comprising spaced strips secured to the. upper edges of the sid-es of said recep tacle by means oli' screws 4. A slide` plate 5 is` provided having' transversely arranged narrow plates 6 secured in spaced relation to each other upon the upper side therezoh the opposite ends oi which project beyond the. opposite edges of the said slide plate and; extend into the guides 8 wherebj7 the said slide plate. issupported in slidable relation with respect to the receptacle 1. 'Vhen the slide plate is in the position shown in 1 to 3 inclusive it practical-ly closes the said receptacle.

The slide plate or member is provided at its central portion with an opening 1 0. idecnfred to the underneath side off thev slide plate. or member is a clamping member Yi'l hav'i'ngl a central projecting portion l2 which extends upwardly through the central openingl 10.. The opposite projecting ends 13 of the clamping member 11 are fastened by means of screws 1li to the slide plate or member 5. The upper side of the projecting portion 12r of the clamping member 111 is covered with a sheet ot suitable moisture or.

waterl holding means, such as chamois shin.`

the portions oi' which upon opposite sides of the said clamping member depend, as 1ndicated at 16, and extend' into the water within the receptacle 1. Portions of the said absorbent sheet oi material are clan'iped between the end portions 13 of the clamping member and the adjacent opposing portions of the slide plate-or member 5 so that the said ab-sorbent sheet Aof material is firmly secured in position with a portion thereof overlying the top surface of the part 12 which projects through the opening 1U of the slide plate or member. The clamping member 11 with the absorbent sheet of material thereover constitutes a moistening pad.

The rear portion of the slide plate or member 5 is adapted to extend underneath Iand to"support a pile of stencil cards 20 comprising a marginal framelike portion 21 having secured. upon one side thereof by a suitable adhesive or otherwise a thin fibrous sheet of material 22, usually Japanese fiber paper. The opposite sides of the said fibrous sheets are coated with a suitable gelatine compound. These cards are well known commercial articles of manufacture and need not be further described.

These cards are retained in position one above the other by means of vertical standards or posts 25 secured at their lower ends as shown to the opposite sides of the receptacle 1 and in order to insure satisfactory operation said cards should be held down by means of a weight 26.

For co-operating with the moistening pad carried by the slide plate or member 5, and as shown in Figs. 3, t and 5, a top meistening pad is provided comprising a spring pressed base member over which is stretched a sheet 31 of suitable absorbent material, such as chamois skin, the opposite sides of which extend upwardly through a central opening in a receptacle 35 and over the upper edges of intermediate walls 36 in said receptacle, and then downwardly into receptacles formed between the said intermediate walls and the outer walls of the said f receptacle. The said oppositely disposed re ceptacles or compartments contain water which by capillary attraction is conveyed to the portion of the said absorbent sheet underneath the'lonf'er side of the base portion 3() of the pad. For the purpose of retaining the water and the moisture within the compartments or receptacles upon the outer sides of the intermediate walls 36, I place quantities of absorbent material 37 such as cotton therein.` The base portion 30 of the upper pad structure is adjnstably secured by means of screw bolts 38 to a plate or bar 40the opposite ends of which are secured to the opposite ends of the receptacle 35 by means of screws 4:1. The said pad is pressed downwardly by means of coiled springs 42 the lower ends of which contact with the upper side of the base member 30, while the upper ends thereof contact with the lower side of the plate or bar 40. By adjustingr the screw bolts 38 the position of the pad comprising` the base member 3() and the absorbent covering therefor may be adjusted with relation to the lower side of the receptacle 35 and also so as to cause it to properly cooperate with the lower pad upon the slide plate or member 5. The top of the receptacle 35 is closed by means of a cover 4:5.

In the modified construction of the lop member of the moistening means shown inv Figs. 8 to 10 inclusive of the drawings, the parts 31, 35, 37, 41, 45, and 51 are identical with the parts correspondingly designated in the previous figures of the drawin In the said F 3 to 10 301 designates `the base or body member of the upper or top pad around the under or lower side of which the porous pad sheet or cover 31 extends. The said base 301 is solid or integral and is provided with projections 3011 at its opposite ends which are secured to the central portions of the upper edges of the opposite ends of the receptacle 35 by the screws .ll. In order to keep the two water holding compartments, which are situated at the oppo site sides of the receptacle, supplied with water, I have provided the bottles 311 each of which communicates with one end of one of the said compartments near its bottoni through a pipe connection 3111. The opening through each pipe connection extends thro ugh a stopper' 32 secured to the outer upper end thereof. The mouth of each bottle 'is closed by one of the stoppers 32 as shown. lhen the water in a compartment is lowered to a point below the opening of the pipe connection connected therewith or below the upper portion of said opening, air enters the bottom which is secured to said connection and additional water is allowed to flow from said bottle into said compartment. I-Iowever when the level of the water in said compartment reaches a certain distance above said. opening the flow of water from the bottle ceases because of atmospheric pressure upon the top surface of the water in the compartment, there being a partial vacuum in the upper closed end of said bottle above the water which may be present therein.

liVhen the slide member is in the jiiosition shown in Figs. 1 to 3 ol' the drawings with the pad carried thereby uiulerneath the up` per pad upon the receptacle 35. the said upper pad rests against or upon the first named or lower pad, so that if a stencil is in lplace between the said pads both pads will contact with the central portion thereof, the bottom pad with the lower sideI` and the top pad with the upper side thereof. It should be noted that these pads are of such diniensions that they contact only with that portion of the fibrous diaphragm of the stencils within the outside supporting fran'ie structure 21 thereof. so that no n'ioisture is applied to the marginal or frame portion of the stencil structure. The screw bolts 38 should be so adjusted that the top pad will llt) properly contact with the central portion of the stencil to be moistened when in place between the two pads.

.y .y lv hen the slide: plate or member is in position as shown in Figs. l tol inclusive ofthe drawings, the receptacle and pad carried thereby are supported upon the pad carried by the slid-e, as already indicated,

but in order to prevent relative sliding a wheel or roller 5l which wheels or rollers are adapted to contact with and rest upon the upper edges of a slidable track or support 52 which is of U or yokeshape, as indicated in Fig. 2 of the drawings. The bot:- tom edges of the opposite sides or legs of the member 52 rest upon rollers 55,.` the front rollers being supported within recesses upon the inner sides of bloclts 5d secured to the opposite sides of the receptacle l. The rear rollers 53v are supportedwithin recesses formed upon the inner sides of the lower end portions of the front posts or standards 25 previously referred to. lli/Then in normal or rear position as shown in Fig. l, the rollers 53 are situated in notches 55 in the lower edges of the opposite sides ofvr the meinf ber 52, which notches have cam-acting edges. The forward end portion 52 of the' yoke member 52 is situated between the opposite sides of an inverted U-shaped member 56 which is secured by means of a screw 57 to the under side of the forward end of the slide 5. The depending portions of the said U-shaped device 56 which are spaced from each other as shown in the drawings lmay be regarded as depending lugs. A hooked. finger piece tit) is secured to the forward portion 52 of the member 52 whereby the said member may be readily moved backand forth upon the supporting wheels or rollers 53. When in normal position; that is, the rear position prior to operation, the members 52 and 5 are in the positions shown in Figs. l to 3 of the drawings, in which positions the rollers 53 occupy positions within the cam notches also when the Darts are in said positions. the portion 52 of the member 52 occupies a position adjacent the rear side of the inverted U,-sl`iaped device 56'. As a result of this arrangement and relationship there is a certain amount of lostI motion between the member 52 and the slide member lVhen the member 52 is pulled forward the rearwardly and dow-Limrrdly f inclined portions of the notches 55 ride up upon the rollers. 525 so as to elevate or lift the receptacle 35 and the pad carried thereby` prior to the forward sliding` movement of the slide member 5. Forward movement of the member 52- does not effect forward movement of' the slide member 5 until the portion 52: contacts with the forward depending portion of the device 55; lt is during such forward movement of the member 52 prior to any movement of the slide that the u-pper pad carried by the receptacle 35 is moved.` out of' contact with the lower pad or-with any stencil card which may be in position between the two pads. rlhe subsequent forward movement of the part 52 causes corresponding forward movement of the slide member 5 together with the pad carried thereby and also any stencil card which` may have been situated: thereon and underneath thev upper pad. As the card is carried forward it contacts with theV switch members 61 and is deflected upwardly and isA supported thereon, as indicated in Fig. Llof the drawings.

The stencil cards are successively removed from the bottoml of the pile 201 and are carried forward underneath the upper pad by means of' shoulder 62 upon the upper side ofthe slide member 5 near the rear end thereof; If a card has been previously carried forward underneath thev said upper pad and4 moistened by the said pads it is moved forward from such position underneath the said pad by the forward end of'a rear stencil contacting therewith and: pushing it forwar-d1, as indicated in llig.. rllhe momentum given to the forward stencil -auscs it to slide forward upon the switch plates (il so that when it stops it is in spaced relation to the rear stencil by means of which it has been pushed forward. l-n order to prevent the momentum of the stencil which iscarried forward by the shoulder ('32 from causing it to continue to move forwardly ait-er the slide plate or member is stopped tion s]; rings (35 are provided, the foi-award ends of which bear upon the side portions o't the frame 2l of the stencils, as is clearly shown in the drawings. These springs are held in place underneath shoulders titl upon the inner sides of the forward standards or posts 25. rFhe stencilsr as they are carried forward pass underneath these springs, as isv clearly shown and indicated in Fig. 4.- ofthe drawings.

A stencil having been drawn forward by the shoulder G2 to position underneath the upper pad as shown in Fig. e', the slide plate or member 5 is returned to what has been termed its normal position as shown in F Pf so that the pad carried by the said slide member retmned to position under neath the said stencil and in contact with the central fibrous portion thereof which it is desired to moisten. As already indicated, when the slide is in such position the upper or top pad rests upon the top side of the said portion of the stencil so that both sides thereof are moistened simultaneously and in view of the fact that the pads are of a size to contact only with the portions of said stencils within the marginal frame thereof, moisture is applied to the desired portions only thereof.

In the use of the device a pile of stencils is placed in position inside of the posts or standards 25 as indicated in Fig. 1.. It .is then placed in such position that the operator who is operating the machine to form the markings, such as letters, figures, etc., upon the stencils may conveniently and readily catch hold of the hook-shaped finger portion 6() to operate the partQ` and the slide member 5. As indicated, the operation of the said member consists in pulling the same forward to remove a stencil from underneath the pile of stencils 20 and place it in position underneath the upper moistening pad, and thereafter returning` the slide to normal position. While the operator is marking the card which has been pushed forward from underneath the upper pad the stencil which has taken its place is being moistened.

It will be seen, therefore, that by my device the handling and the moistening of the stencil cards preparatory to marking the same are greatly facilitated so that the operator may mark a substantially greater number of stencils within a given time than heretofore has been possible.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
