IMPR'O VEMENTJN APPARATUS FOR CASTING COMPOSITION ROLLERS.

Specification forming part of Letters Patent No. 182,547, dated September 26, 1876 applicationfiled February 9, 1876.

Toall whom it may concern Beit known that I, MILLARD F. BING-HAM, of the city, county, and State of New York, have invented, made, and applied to use Improvements in the Construction of Apparatus for Gasting'Uomposition Rollers for Printers and that the following is a full, clear, and correct description of my inven tion, reference being bad to i the accompanying drawing making part of this specification, and tothe letters of reference markedthereon, in which Figure 1 is a side view of myimpro-ved apparatus for castingprinters rollers. atop view of the same. Fig. 3 is a cross-section of the same. I

In the drawing, like parts of the invention are indicated by thesame letters of reference. I

The nature of the present invention consists in certain improvements,as more fully hereinafter described, in the constructionof apparatus for casting composition rollers for printers; the object of the invention-being thev construction of apparatus for the purpose set forth, by which i printers composition rollers can be more expeditiouslyand cheaply made,

whileat the same timea better article results.

To enable thoseskilledinthe artsto make and use mywinvention, I will describe the con" struction and operation of the same.

A-shows slotted standards .for supporting the roller-receptacle of my apparatus. These standards are secured or fastened to: thefloor of the apartment in which therollers are to be cast, or upon a platform resting upon the same. B shows the receptacle in which the molds G, to receive the roller-stocks to be covered with composition, are placed. This receptacle B is formed of a section of a cylinder having attached to it the top plate or head and bottom plate, through openings in which top and bottom plates the roller-molds C have their bearings. The receptacle B is also provided with a removable bottom, D, hinged to the same, so as to be easily removed therefrom, the object of which will be more fully hereinafter described. This bottom D is so constructed that when placed in position upon the under side of the receptacle B the lower ends of the molds 0 will be closed, and for this purpose I propose to use a rubber packing secured upon the interior of the removable Fig. 2 is bottom D. The receptacle B has aprojeoting rim or flange, I), attached upon its exterior surface, upon which rest two circular platesor collars of metal, 0 0 between which are pinned a series of rollers, 11, havingtheir bearingupon the exterior of the receptacle B, and to which are fastened the spindles e for supporting the receptacle B in the slotted stand ards or uprights A. From the exterior of the receptacle B also projectstuds, uponwhichare therollers f, free to revolve thereon, and having their bearingupon the upper side of the upper collar 0. Upon one of the spindles e is secureda ratchet-wheehg, and to the end of this spindle is attached the crank or handle h. An eye, i, is secured about centrally in the top-plate of the receptacle B. l is an inlet-pipe in theireceptacle B, :for the introduction of steam into the same; m, an inlet-pipe,

for the introductionof water into the same; a

and n, anexit-pipefl'or the-water fromthe receptacle B. 1

tion to be poured into the molds G to formthe rollers, and which hook Gr engages with the eye 6 when the receptacle B is to be raised or lowered.

Such being theconstruction, the operation may be thus described: Thereceptacle B having had inserted in it the molds (J, in which the rollers are to be cast, is inserted in the slotted portions of the standards or uprights A, the spindles e resting in the same, the receptacle B occupying a vertical position, as shown in Fig. 3 of thedrawing, and being retained in such position by a ratchet, 0, pivoted to the upper portion of one of the standards A, and engagingwith the ratchet-wheel g. In this position the receptacle B is turned by the crank h from the vertical into a horizontal position by disengaging the ratchet 0 from the ratchet-wheel g, and after the receptacle B has been placed in this horizontal position, depressing the ratchet 0 until it engages with the ratchet-wheel g, and serves to hold the receptacle in this horizontal position.

In this position the molds G are oiled or greased, so that after being cast the rollers may be easily delivered from the molds O. The stocks to be covered are placed in position within the molds O, and the removable bottom D is hinged to the receptacle B.

The ratchet 0 is then released from contact with the ratchet-wheel g, and the receptacle B is brought back into the vertical position it originally occupied by turning the handle h, and secured therein by the ratchet 0 engaging with the ratchet-wheel g.

It will be found advantageous before the pouring operation to introduce a current of steam into the receptacle B through the inletpipe Z, sothat the chill may be taken off the molds, and the same to a certain extent be warmed or heated. The kettle H, containing the melted composition, of which the rollers are to be formed, is now attached to the hook G" upon the end of the rope or chain F, and by means of the Windlass is raised until it is brought over the receptacle B. With the kettle H in this position the receptacle B, provided as it is with the rollers f, and encircled by the collars c c supporting the roller d, may be readily revolved by the hand of the operator until each one of the molds G has been brought into the proper position relativelyto the kettle H to be filled with composition from it.

After all the molds C have been filled a current of cold water may be introduced into the receptacle B through the pipe m, and passed through the same, and allowed to flow off through the pipe 12. This will have the effect of hastening the hardening or solidifying of the composition introduced into the molds 0.

.At the proper season the receptacle B may be turned from the vertical position into the horizontal position, as herein alreadyset forth, and secured in this position, the bottom D being unhinged and disconnected from the receptacle, and the rollers drawn from or forced out of the molds 0 held in the receptable B.

By the use of an apparatus constructed as described, the process of casting printers roll ers is not only expedited, but the cost of so doing is lessened, and a better roller-results.

Having now set forth my invention, what I claim as new is 1. In an apparatus for casting printers composition rollers, an oscillating receptacle, B, provided with a removable bottom, D, in combination with the slotted standards A, constructed and operating substantially as de-' scribed, for the purposes set forth.

2. In an apparatus for casting printers com position rollers, a revolving receptacle, B, pro-.

vided with a removable bottom, D, in combination with the slotted standards A, constructed and operating substantially as and for the purposes set forth.

3. In an apparatus for casting printers composition rollers, the combination, with the re ceptacle B, provided with a removable bottom, D, of the inlet-pipes l and m for the introduction of steam and water, and the exit-pipe n for the Water, for the purposes fully set forth.

4.. In an apparatus for casting printers com-v position rollers, the combination, with the slotted standards A, of the receptacle B, having upon it the flange b, and provided with v a removable bottom, D, the collars c 0 to which are attached the spindles e, the ratchet-wheel g, and ratchet 0, substantially as and for the purposes indicated.

5. In an apparatus for casting printers composition rollers, the combination, with the slotted standards A, of the receptacleB, having upon it the flange b, and provided with a removable bottom, I), the collars c 0 rollers 61, and rollers f, substantially as and for the purposes set forth.

In presence of A. SIDNEY D'OANE, J os. E. HE LEY.
