' v DEVICE FOR rIVIAKING- SIGNS.

Apiaucauon fried nar-ch 27, 192e. serieu No. 97,977.

The principal feature of the invention consists in providing a weighted frame structure and characters supported thereon which are provided with resilient surfaces l to engage thesurface of the sheet on which the sign is to be defined to form a clearly defined outline.

In the drawings, view of a device constructed in accordance 1 5 with this invention.

Figure 2 is an enlarged cross sectional view through the line 2-2 of Figure' 1.

Figure 3 is a perspective detail of a. sign letter showing thefresilient surface.

In the manufacture of metal signs galvanized sheets are usually employed and on these the desired characters Aare arranged,

It has been proposed to use cut out letter blocks to represent characters desired on the sign and to place these on the surface of the sheet and to apply the paint around them, but such structures have not been found satisfactory, owing particularly to the peculiar wavy quality of metal sheets.

The present invention. overcomes this difticulty and enablesvthe production of a sign by means of an air brush application of the pigment, the characters Ofwhich will be clean cut and will be all alike. K

rPhe device consists of a frame 1, here shown constructed of channel iron sections and provided with ay plurality of longitudinal and transverse cross bars 2 and 3 arranged in the form of a grid,.the under side surfaces being flush. The frame 1 is hinged to a suitable table top el; by the raised Or offset hinges 5 so that the frame is quite clear of the table surface.

The letters 6 or other characters or border forms 7, which are to be represented on the sign, are formed preferably in heavy cast metal, such as iron and of a depth greater than the thickness of the `frame 1.

To the underface vOf these letters Or characters is cemented ory otherwise secured a surface 8 of rubber or other suitable resilient material which will form a Olean out Figure 1 is a perspective l on the table,

line of contact around the edge of the character to be reproduced on the sheet.

rlfhese various characters are secured to the underside of the grid by means' of suitable screws 9 placed through holes in the cross bars so that they will be firmly held in a positive position.

In the use of this device the frame is lifted clear of the table surface, being swung back on its hinges 5 and a sheet of metal the desired size-is placed in position on the table top. The frame is then swung downwardly so that the surface of the letters engage and by reason of the securing of the characters to the frame, by means of the screws 9, any desirable adjustment of the letters may be made so that they may malre proper contact.

The weight of the frameand of the heavy cast metal let-ters holds the sheet tightly down to the table surface and the resilient face of the letters engages the sheet metal surface in Yclose contact forming with the metal sheet, a clearly defined line of contact throughout the entire periphery Or outline of the letter.

The paint is then spread on to the metal surface with an lair brush, the open frame allowingthorough access around all sides of the characters.

The letters Vor characters vthemselves are made of such depth that there will be ample room to manipulate the air brush-to very effectively coat the surface.

It will be readily understood that when a considerable quantity of metal signs of a certain design are required, this device when once set up will enable the very rapid production of the signs required.

There will be no setting of the letters, no adjusting of the separate parts, no clamping members of any kind to manipulate. It is simply necessary to swing the frame upwardly, place the required sheet in position drop the frame into place and apply the paint, then swing the plate clear and remove the finished sheet.

Y What we claim as our invention is f 1. In a device for making signs, the combination with a.V resilient faced type, of a weighted frame having rigid bars extending longitudinally and transversely in a common plane, said type-being secured rigidly to the underside of said bars and held by the frame, a plurality of rigid bars extending transversely of the frame and having their under surfaces arranged 1n a common plane with the under surfaces of the former bars,V

and means secured in said frame for securing said type to the undersurfaces of said bars. JOHN BAGNALL. PERCIVAL Gr. 'COPEMAN
