MEANS FOR ATTACHING STENCIL-SHEETS TO DUPLlCATlNG-MACHINES.
SPECIFICATION forming part of Letters Patent No. 739,498, dated September 22, 1903.
Application filed October 3, 1902 useful Improvement in Means-for Attaching Stencil-Sheets to Duplicating-Machines, of
which the following is a description.
My invention relates to improvements in means for attaching stencil-sheets to duplicating-machines; and my object is to provide a simple, efficient, and cheap device for the purpose.
In the drawings, Figure 1 is a section through a portion of the stencil-carrier of a duplicatingmachine of common, form with my present improvements thereon, and Fig. 2 a perspective view of the fastening device viewing the same from the under side. 7
Corresponding parts are represented by the same numerals of reference.
The duplicating-machine, as is common, is
provided with the-two bars 1 1", forming a vertical slot between them. One of the bars may be provided with a notch 2 on its inner face. The stencil-sheet 3 is stretched in position over the stencil-carrier and near one end is engaged within the slot between the bars 1 l by a locking-plate 4:. This lockingeplate is struck downward to form a spring-rib 5, which forces the stencil-sheet within the slot. Preferably the spring-rib is provided with offset tongues 6, which engage the recess 2 in one of the bars 1, thereby holding the lock firmly in place. The extension 7 of the lock is curved, as shown, so as to follow the periphery of the stencil-carrier, and acts'as a protector for the sheet to receive the impact of the impressionroller in the operation of the machine. When the sheet is to be removed, the extension 7 of the lock is pressed toward the rib 5 to withdraw the tongue 6 from' the recess 2, thereby releasing the lock and permitting its ready removal.
Serial No. 125.783. (No model.)
The device is very simple and cheapin construction and in addition to effectively holding the stencil-sheet in' position also acts as a protector for the sheet from the eflect of the impression-roller, as explained.
I claim isv 1. The combination with a stencil-carrier having a slot therein, of a locking-plate having; an elastic rib for holding the stencil-sheet in said slot, substantially as set forth.
2. The combination with a stencil-carrier having a slottherein, of a locking-plate havin g an elastic rib for holding the stencil-sheet in said slot, and a tongue on said ribengagtially as set forth.
3. The combination with a stencil-carrier having a slot therein, of a curved plate protecting the stencil-sheet, and an elastic rib on said plate for securingthe stencil-sheet in said slot, substantially as set forth.
4. The combination with a stencil-carrier having a slot therein, of a curved plate protecting the stencil-sheet, an elastic rib on said plate for securing the stencil-sheet in said slot, and a tongue on said rib engaging a recess at the side of the slot, substantially as set forth. I
5. As a new manufacture, a locking-plate AUGUSTUS D. JKLABER.
