The present invention relates to improvements in stencil cutting devices, and has for an object to rovide an illuminated board or support for olding the pattern and stencil 8 whereby the stencil may be prepared for the mimeograph machine. The invention is also applicable to drafting boards and the like.

The chief purpose of the invention is to provide a device of this kind which will be 1 readily portable, com act in size and construction, simple and ight in form, yet possessing substantial strength.

Other objects of the invention are to produce an improved light yet strong illuminating casing, to provide an improved board construction on such casing and to improve ghee camp construction for the glass base or scribed hereinaftenand will be more particulprly pointed out in the claims appended ereto.

Referring more. particularly to the drawings the device is composed generally of a casing and a board supported thereon.

The casing is shown to have a bottom 8, end walls 9and 10 and side walls 11 and 12. The casing is referably made from thin sheet metal whic and portabilit 4 The walls of the casing are shallow so as to adapt the device to be placed upon a desk,

With the foregoing and other objects in. view, the invention will be more fully de-' In the drawings, wherein like symbols refer to like or corresponding parts throughout the 'as indicated at 17 to receive screws,

is recommended for its lightness table or other convenient support without raising the board on which the work is done being ower as to height than the opposite end wall 10, and the upper edges of the side walls 11 and 12 inclining accordingly from one as end wall to the other. The board is thus supported on an inclination, as shown.

Now the thin walls of the portable table are required to support the rather heavy" board, the same being also called u on to provide attachment to the board. he u per edges of the walls are, with these en s in view, constructed to reinforce the casing, as shown in Figure 5, in which the

flanges

14, 15 and 16 extend at right angles to the res ective planes of the side walls 11, 12 and t e end wall 9. The flanges referred to are bent outwardly from the several walls and perforated or other fastenings, by which the flanges and the 085- so ing as a whole are secured to the lower surface of the board.

Now it will be noted that the

flanges

14 and 15 do not extend the entire length of the side walls 11 and 12, but they terminate short of as the lower end wall 9. In initially stamping the casing from the blank of sheet metal material of which it is made, the .upper edges of the side walls throughout are formed. with the flanges, but after-the stam ing operation, such flanges are cut through a ong transverse lines indicated at 18 and 19 and the portions of the flanges between the

points

18 and 19 and the end wall 9 are folded or bent down outwardly upon the exterior surfaces of the 96 respective end walls 11 and 12. This construction is clearly shown in Figure 2. This doubled construction sti-flens and reinforces the upper ed es of the side walls 11 and 12 and stifiens t e casing as a whole in a longi- 10o tudinal direction. Preferably the lower end wall 9 is not provided with any stiffening members as owing to the proximity of the stiffening flange portions and 21 of the side walls, no particular strength is needed in the shorter end wall 9.

However, the opposite or higher end wall 10 is provided with a flange 22 which is folded they do not extend to the opposite end wall 9 which is unprovided with any stiffening flange. The offsetting of the side stilfening

flanges

20 and 21 from the end stiffening flange 22 enables the upper casing wall edges to provide a suflicientintegral attaching surface to the board, while also affording ample strength in the light sheet metal casing.

The board is made in sections of which 23 and 24 are side styles and 25 and 26 head pieces. The ground glass or other transparcut or translucent board proper is indicated at 27. The side styles are provided with the reduced

ends

27 and 28, mortises being made in the upper surfaces thereof to receive the

tongues

29 and 30 of the

head pieces

25 and 26.

As shown in Figure 3 screws or

other fastenings

31 and 32 are provided to hold the overlapped parts together. As also shown in Figure 3 screws or

otherfastenings

33, 34 and 35 are employed to secure 'the attaching flanges of the casing to the side styles and head piece 26 of the board.

The head piece 25 is provided with the usual means for attaching the end of the stencil and tracing which are superposed upon the board 27 for the purpose of cutting and preparing the stencil for its use in the mimeograph machine.

The

side styles

23 and 24 are provided with longitudinal similar slots 36 which extend into the head piece 26. These slots are formed at one end with the enlarged rounded perforations 37.

Clamps 38 for the glass 27 are provided with shanks 39 fitting slidably in the slots 36. Washers 4O and41 extend about each shank 39 below the style bar; and between the

washers

40 and 41 are wound coil springs 42. The ends of each shank 39 are split and over-turned in opposite directions, as indicatedat 43 and 44, particularly in Figure 3.

An electric lamp 45 or other source of illumination is mounted in the casing, the interior of which is preferably tinned, mirrored or coated with some other bright substance to heighten the efiect of the lamp and to brilliantly reflect the image on the glass.

and 52 upon the head piece 25. A separate metal or other clamp piece 53 is carried by the intermediate portion of the head piece 26 and provided with a downwardly bent overhanging end for engaging against the beveled end 50.

; In the use of the device, a drawing, or other master sheet and stencil are placed upon the frosted glass 27, the lamp 45 being energized as by connectin to the house light circuit. The stencil may then be cut. The inclination at which the board is supported, the use of the yieldable feet 13 and the elevation at which the device is supported upon an ordinary desk or table top will lend conjointlyto' the easy and quick cutting of the stencil. I

When the need for transportation arises, the device will be found readily portable by reason of its light weight and small size; yet when the pressure of the hands and body are put upon the board, the stiifness and reinforcement in the casing will resist any tend ency of the Walls to buckle or crumple. The clamps 38 may be adjusted along the slots 36 and may be taken out through the openings 37 when required. The casingmay be removed by unfastening the

screws

33, 34 and 35 to give access to the interior of the casing for replacing bulbs, etc.

' The ground glass 27 may also be removed by removing the clips 38 and the keeper piece 52 which is held to the head 26 by a screw or other fastening.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such chan es and modifications being restricted only by the scope of the following claims.

2. A stencil cutting devicecomprising a shallow casing having its bottom, ends and side walls of thin metal, one of said end walls being lower in height than the other, and pro vided along its upper edge with an outwardly projecting narrow flange, said side walls inclining from one end wall to the other and provided along its upper edge with an outwardly projecting narrow flange cut away adj acent said lower end wall, a source of illumination contained within said shallow casing, a frame comprising side styles and head pieces attached to said narrow flanges and extending outwardly beyond same, a translucent supporting board carried by said frame, said side st les and head piece adjacent the lower end 0 said frame provided with elongated slots, and spring pressed clips movable in said elongated slots ,to hold sheets of various lengths above said translucent supporting board.
