STENCILING-MACHINE.

To all whmn it may concern:

Be it known that I, STEPHEN '1. SMITH, Jr, a citizen of the United States, residing in Stamford, in the county of Fail-field and State of Connecticut, have invented certain new and useful Improvements in Stenciling-Machines, of which the following is a specification.

This invention relates to stenciling or duplicating machines, and particularly to those in which a stencil is wrapped upon a large cylindrical ink-screen, the sheets of paper to be stenciled being run between said ink-screen and a pressure-roller and stripping off from the ink-screen and piling up on the delivery side of the machine, machines of this class being illustrated in Letters Patent No. 832,217.

In manufacturing such machines for the market it is desirable to provide a paper-receiving or delivery shelf u on which the stenciled sheets may pile, and this shelf must be of suflicient length to receive the longest sheets that are to pass through the machine, which pile up against the ledge at the end of the shelf. t'is found that short sheets passing through the machine do not pile up properly on a shelf which is the suitable length for lon g sheets, but slide one under another and become disarranged and skewed upon the shelf, there by tending to rumple the sheets and also rendering it necessary to handle them to an undesirable extent thereafter and besides incurring liability of blurring the fresh ink upon the sheets. In order to overcome this obj ection, I have devised a shelf which is long enough for the longest sheets and which can be shortened as required to make it the proper length for short or medium length sheets.

In the preferred form of the invention I make the shelf of two plates of about equal width and arrange these plates to telescope together cndwisc, soas to lengthen or shorten the shelf,

In the accompanying drawings, Figure l is an end elevation illustrating a stencilingmmchine with niyimprovenients applied thereto, a sheet of paper beingshown passing through the machine and about to drop upon the shelf upon which other sheets have been piled.

Fig. 2 is an end elevation of the shelf. Fig. 1}

is a perspective view showing the shelf del latter carried upon arms 4, hinged upon a pair of bosses 5 at the opposite ends. of the machine. A sheet of paper 6 is shown passing between the pressure-roller and the stenoil-cylinder.

The improved deliveryshelf comprises a thin metal plate 7 of a width to extend substantially the usual length of the cylinder 1' anda similar plate 8, which has a telescopic connection to the plate 7,- so that the plates may be drawn out or pushed in to lengthen or shorten the shelf, considered as a whole. The side edges of the shelf 7 are folded underneath, as at 9, to form guides for. the side edges of the plate 8. The latter has at its free end a ledge 10, against which the leading edges of the sheets of paper. 6 rest, as at Fig.

1. At its upper end the plate 7 is provided with hooks 11, one at eachside, to, catch over the bosses 5, whereby the shelf is detachably hinged upon the framework 2, between the ends thereof. The ledge 10 rests upon the table 12, and when the shelf is shortened or lengthened the shelf will turn upon the bosses 5 to permit the ledge end of the shelf to drop to the table.

Having thus described my invention, I claim- 1 i 1. A delivery-shelf for a stenciling-mw chine comprising a plate having a sheet-receiving ledge, and a second plate having its edges foEded over to receive the first plate; means being provided for hanging the second plate loosely upon the stenciling-rnachine so that said ledge in. rest upon the table. r 2. A delivery-s ielf fora stenciling-machine comprising. a plate having a sheet-1e ceiving ledge, and a second plate having its edges folded over to receive the first plate;

and hooks provided upon the second latefor catching over bosses upon the stencilingmachine.
