APPARATUS FOR MAKING PRINTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. 444,206, dated January 6,1891.

Application filed April 5, 1890. Serial No. 346,675. (No model.)

To all whom it may concern.-

Be it known that I, LEANDER K. BINGHAM, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Making Printers Rollers; and I do hereby declare the following to be a full, clear, and exact .description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.

Figure 1 is a vertical section. Fig. 2 is a bottom view of the annular plate. Fig. 3 is a section thereof. Fig. 4 is a top view of the removable bottom. Fig. 5 is a bottom view thereof.

This invention relates to improvements in apparatus for making printers rollers.

In devices of. this kind it is usual to have to the apparatusa removable or supplemental bottom which is common to all the moldtubes, so that composition admitted to one tube or into the bottom at one point will flow into all the mold-tubes. In a device of this kind, after the rollers are formed in the mold-tubes, the supplemental botttom is removed and the completed rollers withdrawn from the mold-tubes. Where these rollers are large it is found in practice that when the bottom is removed and the rollers drop down together it is very difficult to handle.

them.

The present invention is devised to obviate the difficulty arising in using the old device.

The invention consists in a removable bottom perforated so as to allow the rollers to be removed separately from the apparatus.

In the annexed drawings, the letter A indicates a suitable frame or casing for the mold-tubes. or upper head (not necessary to be shown) and the usual lower head B. In the latter are the holes I), with the glands or rings 1), wherein are held the lower ends 0 of the mold-tubes G.

The letter D represents the removable or supplemental bottom common to all the moldtubes. This bottom D is made with perforations d, registered with the holes in the lower head of the apparatus and of a diameter large enough to permit the passage of the completed rollers. These perforations d This casing has the usual top,

are countersunk or rabbeted at d on the under side. In these perforations d are fitted annular plates E, having shoulders 6, adapted to the counter-sinks or rabbets d, and the shanks e of the rings tit up into the perforations d. These annular plates are held in place by any suitable device-as,forinstance. the turn-buttonsf. (Shown in Fig. 5.) The roller-stocks G are held in place in the moldtubes, their ends g resting in the bushings h; The annular plates E have the central holes 6 which are large enough to hold the stems h of the bushings 72/, the stems of the rollerstocks protruding down through these bushings. The supplemental bottom is first placed on, the bushings are put on the roller-stocks, the annular plates are placed on the bushings, and then the stocks, with the bushings and annular plates, are put into place and the buttons turned under the plates,holding the whole in position.

To remove the rollers the annular plates are removed first from the bottom, leaving perforations larger in diameter than that of the rollers. The latter are then withdrawn one after another, as desired.

Having thus described my invention, what I claim is 4 1. As an improvement in apparatus for making printers rollers. a removable bottom provided with perforations having a diameter greater than that of the rollers to be made, as set forth.

2. The combination of the frame or casing having the mold-tubes with the removable bottom provided with perforations having a diameter greater than that of the rollers to be made and registered with the holes in the lower head of the casing, as set forth.

3. The combination of the frame or casing having the mold-tubes, the removable bottom provided with the perforations having a diameter greater than that of the rollers to be made and registered with the holes in the lower head of the casing, and the annular plates fitting in the perforations, as set forth.

In testimony whereof I afix my signature in presence of two witnesses. I

LEANDER K. BINGHAM.
