I PRINTING DEVICE.

Specification of Letters Patent.

Patented'Jan.20,1914.

Application filed June 1a, 1913. Serial no. 773,429.

' T all whom it may concern:

Be it known that I, JOSEPH S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Printin Devices,

' of which the following is a speci cation.

- the'type and 'which'will present only smooth and rounded surfaces along the longitudinal margins thereof, thus obviating any tendency of the devices-to interlock or cling together.

ence to the following description when considered in connection witht-he accompanying. drawings.

- Referring to the drawings-Figure 1 is a face view of a printing device embodying my Invent on; and Fig. 2 1s a transverse sectional' viev; takenpn the line 2-2 of "Fig. 1.

The printing device is preferably formed of asingle sheet of metal provid ng a central printing portion 5 from the body of which the printing characters 6 are stamped up, and the marginal spacing portions '7 adapted to space the devices apart to preventinjury to the printing characters when the devices are stacked or nested. The spacing portions are formed by bending the metal along each longitudinal edge of the .printing portion first upwardly and outwardly to provide the inclined portion 8, and then outwardly to form the flat face 9 which is disposed substantially in the plane with the printing faces of the printing characters 6. The metal outside the faces 9 isthen rolled downwardly'and inwardly,-the edges .11 being elevated slightly with respect to the lower faces 12 of the margins and terminating beneath the inclined portion Sadjacent to the edges of the printing he invention in one of its preferred em bodiments will be best understood by referthe entire length of the device, above and portion andsubstantially in the plane of the print ng portion. The lower faces 13 of the margins, are, therefore, inclined upwardly from the lowest'point '12 and the edges 11 of the metal are protected so that no=corners or edges are exposed which might engage with adjacent devices in a stack and cause the devices to' interlock or cling together.

,If it be desirable to-arran e thedevices' in accordance with a card in ex system the spacing flanges'may be provided withv slots to receive suitable index tabs, or, the index tabs may be, attached thereto in any well.

known or referred manner.

It will e manifest that mynovel printing device presents no sharp, edgles or cor," ners, that the marginal spacing arfg es ex tend both above and below the normal plane the devices are stacked together the spacing flanges Wlll space the devices apart suffi; ciently' to prevent contact with or injury to of the metal and, that when a. number of the printin faces of the printing characters on onedevlce by a contiguous device. I claim:

1-. A sheet meta-l printing device, comprising a printing portion,and longitudinally disposed marginal spacing portions extend ing at the edges of the device, throughout below the lane of the metal from which-the printing characters are formed, and having the longitudinal edges of the metal disposed contiguous to the printing portion of the device so as to be incapable of engaging with.

a similar device, the ends of said device between the spacing portions being disposed in the original lane of the metal from which the device is formed.

2. A sheet metal printing device, comprising a printing portion having printing characters stamped up therefrom, and a longitudinally extending marginal spacing portion, the upper face of said spacing portion being disposed substantially in the plane of the printing faces of the printing characters on said printing portion and the lower face of the spacing portion being disposed below the plane of the metal from which the printing characters are stamped up, the lower faces of said spacing portions being inclined upwardly from the margln of the device toward the printing portion.

3. A sheet metal printing device, compris ing a. printing portion having printing char- 110 -acters stamped up therefrom, and longitudiupwardly from the outer edges of the device toward the printing portion.

4. A sheet metal printing device, comprising a printing portion having printing characters stamped up from one face thereof, and longitudinally extending marginal spacing portions comprising the margins of themetal bent upwardly substantially flush with the upper faces of said printing characters and rolled'downwardly below the plane of the lower face of the printing portion and then inclined upwardly to dispose the edges of the metal substantially in the plane of the printing portion and at the edges thereof.

.5. A sheet metal printing device, compris-.

ing a printing portion provided with print-' ing characters stamped up from the body of the metal, and marginal spacing portions extending-above and below the body of the printing portion, said spacing portions consisting of the longitudinal margins of the metal sheet bent upwardly, then downwardly and'inwardly, and again upwardly to position the edges of the metal above the lower faces of the spacing portions.

' 6. A printing device comprising a metal sheet prgvided on one face with printing characters stamped up from the body of the metal, the metal along the longitudinal mar gins of the device being bent to dispose the upper faces of the margins at the edges of the device above the normal plane of the metal from which the characters are stain ed ,up and the lower faces of the margins e'low the normal plane of said metal, the edges of the metal terminating within the boundaries of the margins and above the lower faces thereof.

7. A printing device comprising a strip of sheet metal having marginal spacing portions extending above and below the normal plane of the metal strip along the longitudinal edges thereof, the metal forming said spacing portions being elevated at the margins of the device above the original plane and then bent downwardly and inwardly to dispose the edges-thereof beneath the elevated portions and substantially in the original. plane of the metal.
