' STENCIL-PRINTING MACHINE.

To all whom it may concern." 7

Be itknown that I, Gnarls S. TANNER, a citizen of the United States, residing at San Francisco, in the countyof .San Francisco and State of California, have invented certain neiv and useful- Improvements in Stencil-Printing Machines, of which thefollowing is aspecification.

This invention consists of asimple device fewfzrcilitating printing of posters, notices, dodgers, signs, and similar matter by means of stencils.

In its more specific construction the invention embodies a peculiarform of frame adjustabl'e to permit of printing large or small printed matter, and peculiar securing means for connecting the stencils with the frame,

. the" parts 'of.'the frame together, and the whole device to its base.

For a full comprehension of'the invention including its me'rits and advantages 'referonce is to be had to thefollowing detail descriptiongand to the accompanying drawin s in whichigure I is aplan View of a device embodying'the essential features of the invenparts.

Throughout the drawings and description similar reference characters refer to similar Specifically describing the invention as illustrated it Will be observed that the'device is mounted upon a suitable base 1 and comprises a frame composed of the opposite sides 2 and the top and bottom sides 3. The sides 2 and 3' are slotted nearly the entire length thereofand said slides are connected. together by means of adjusting plates 4. The plates 4 each consist of a body portion having a central a erture 5 and outstanding corner lugs 6.. ,uaoh plate 4 fits against the under side ofthe sides 2 of the frame, and the corner lugs 6 project outwardly so as to engage with the upper and lowii edges of the sides 3 which are received between the upper and lower pairs of legs of each plate' A suitable fastening in the form Specification ofLetters Patent.

plate 4 at each corner of the frame, and also through the slots in the connected sides and 3, said fastening being shown at T and permitting of ready adjustment of the sidi of the frame to increase or decrease the s of the space in which the stencils are arranged. Suitable plates 8 having -pro3ect1ng laterallytherefrom are secured pintles 9 tothe base 1, said pintles 9 being received in sockets of plates 10 attached to the upper ends of the sides In other words, the frame -arrying the stencils is pivoted at one end to the base 1 and its free end may be readily raised -or. lowered to facilitate the removal of'a printed sheet or poster from beneath the frame, the plates 8 being detachably secured to the base' by thiunb-screws to permit adjustment of the sides of the frame.

' The stencils are shown at 11 and preferably consist of plates having flanges at their edges, preferably the side edges, the several flanges of the stencils being adapted to hook over one another in the formation of a line of stencils as shown most clearly in the drawings. Anysuit'ablcmoans may be used, however, for connecting the stencils together, this bcing immaterial within the spirit of the invention.

For mounting each line of stencils and its connected blankson the frame it is contemplated to provide a plurality of line holding plates 12, said plates comprising an outer transversely slotted portion and an inner line supporting member 12". An end portion of each plate 12 is bent to form the line supporting member 12 in spaced relation thereto, said lincsupporting member 12' having a flange on its free edge adapted to interlock or engage that of a stencil or blank connected with and forming a part of the stencil line. The lineholding plates 12 are attached to the sides 2 of the frame by means of fastenings 13 which pass through the slots in the sides 2 and also through the slot in the outer body portion of the plate 12 which rests in contact with the inner face of the sideQ adj accnt to which it is arranged.

It will beapparent that the mounting of the plates 12' is such that they may. be readiiy adjusted iongitudinally ot' the sides 2 and according to the number of lines of stencils to beused for printing the sheet.

Patented Friar. 22., 191th The invention is very simple in construction but permits of considerable adjustment of the parts for the purposes for-which it is designed. The mounting of the frame in a pivotal manner on the. base is also advantageous for ob ious reasons.

The lincsot stencils are spaced from the rear side of the frame by reason of the peculiar formation of the plates 12 and they will lie inclose-contact with the sheet when the frame 13 in its normal position.

The frame of the device is adapted to be extended so as to be practically double the size shown in l igs. l and 2 of the drawings. For the above purposes the sides 2, as well as the ends 3 are made in sections arranged one above the other and in close contact, the

- lowermost sections of the sides and ends be- -nally until they reach the desired positions in which they are adjusted by said fast'crr iiigs T. .l tll'tl\ttl'llitil't) the. plates 8 having the bearings for the pintlcs t) are secured to the base 1 by thulab-screws, whereby the location of said plates may be adjusted lll'Ol'tltl' to accomniod ate for adjustment for the size oi the -l'i'ame of the device.

it may be noted that the metal line holders '12 have their outer portions received bci tween the sertioi'is of the sides and ends of the frame. noi'inally,which latter practically clamp the members l2 iii-position when the .l'astcnings 11-) are tightened. However, when the sections of the sides and ends of the frame are so adjusted as to increase the size of the frame the outer slotted portion of the 1 members 12 are secured in contact with the inner sides of the outer sections and the outer sides of the inner sections, so that the li'neholder will snpport the lines of stencil t in the same plane and for proper printing.

The imnlilication of the invention shown in .l 'ig. (3 illustrates one other method of connecting the stencil and blanks together at adjacent edges. In this construction the stencils are connected by means of hooks. at the edge of one stencil engaging in slotsor openings at the edge of the adjacent stencil.

It is to be understood of course that any 5 suitable means may be employed for connecting the stencils together.

Having thus described the invention,what;

is claimed as new, is

t. A stencil printing frame comprising a plurality of sides slotted longitudinally thereof, adjustable connecting means for said sides comprising corner plates having outwardly projecting lugs between which certain sides of the frame extend longitudinally of the plates, the opposite transversely i arranged sides of the frame extending between said lugs also, stencils connected with the frame andfastening members passing through the plates and the slots of the sides of the frame to adjustably hold said parts in connection.

frame comprising a plurality of sides, adust-able connections between said sides, and supporting means for lines of stencils cont'he frame and having line holding members in spaced relation thereto, said line holding members being provided with means for connecting the same with a line of stenoils and blanks.

3. In con'ibination, a. stencil printing frame con'iprising a plurality of sides, stencils, and means for supporting the stencils in proper relation on the frai'ne including line supporting plates, each line supporting plate comprising a slotted side, a -stencil engaging side in spaced relation thereto, and a fastening passing through the slot of the slotted side and securing the plate to a side of the frame.

4. In con'ibination, a stencil printing frame comprising a plurality of sides, each side consisting of superposed slotted 'secttions, fastcnings connecting-the sides and near adjacent ends and passing through the. slots to permit of adjustment, of said sides 3 and the sections thereof, a stencil supporting device for the frame comprising line supporting plates, each line supporting plate l l l being bent to provide spaced sides, one, side having a slot therein and being received between the sections of a side of the frame, {and fastenings passing through the slot-of l the line supporting plate dctachabl and adi justably thereto, the other side 0 the line I supporting plate being adapted to interlock i with a stencil substantially as and for the f purpose set forth. j In testimony whereof aiiix my signature 1 in presenceof two Witnesses.
