srncrmcnrrorr forming part of Letters Patent No. 533,541, dated fiebmary 5,1895. Application filed April 9, 1894- Serial No. 506,868. (No model.)-

Zb all whom it may concern:

Be it known that I, ESOM O. LEACH, a citizen of the United States of America, residing at Fairmount, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Mold-Sanding Machines, of which the following is a specification, reference being had therein to the accompanying drawings. a

This invention relates to mold sanding machines to be used in connection with steam power brick making machines.

The object of the invention is to dispense with the help usually required for sanding the molds, increase the output of a machine of given capacity, preventing the waste and the scattering of the sand and obtain an even and uniform sanding of the molds.

The improvement consists of the organized machine and the novel construction and combination of the parts which will hereinafter be more fully described and claimed.

In the accompanying drawings,--Figure l is a side elevation of a machine embodying the invention, showing the operation of the same, a mold aboutto be dropped into the sand box, one in position to be removed and others sanding. Fig. 2 is a top plan view of the machine. Fig. 3 is a detail view of the adjustable bearings and the means for moving the same to throw the machine in and out of gear.

Similar letters referto corresponding parts in the several views.

The sand box is composed of two ends or heads A, preferablyof cast iron, and a semicircular casting B, of sheet metal, steel being preferred. The edges of the casing are let into grooves provided in the heads and the latter are secured in place in any desired manner preferably by the rods 0, which pass through apertured cars a, on the heads.

A shaft D, journaled in the heads A, is provided at one end with a gear wheel d, meshing with a pinion f, on a short shaft F. Upon'this shaft D, is mounted the mold carrier consisting of heads G, and sand lifting.

plates H. The heads G, are open spiders, the spokes radiating from tubes keyed to the said shaft D. The perimeter of the heads has a corresponding series of straight faces a, j, k. The faces 70, extend approximately gradial'ly and the faces j, at right angles to fthefaces 7c. The faces 11, incline from the faces is, and form seats for the plates H, ,1 which are secured thereto. The contiguous faces j,.and lc, form seats for the molds, one i closed side of the mold resting on the face It, and the open side on the edges j. The forward or advancing edges h, of the plates H, project beyond the faces It, to approach close to the bottom portion of the casing 13, to scrape up the smallest amount or quanity of sand in the box. The plates may be imperforate or have openings as required.

A bracket K, is attached to the head of the box and forms a support for a movable hearing box is, in which is journaled the shaft F. Parallel slots are provided in the brackets to receive bolts n, by means of which the said bearing box is held on the brackets. shaft 0, journaled in the bearing box 70, and adapted to be turned by a suitable handle 0, has an eccentric portion p, which works in a transverse slot P, in the bracket K. On

turning the stub-shaft the bearing box will bemoved to bring the pinionf, in or out of gear with the gear wheel d, as required. The band wheel Q, is keyed on the shaft F. The gearing is such that when the machine is run at the required speed a mold will be sanded and brought into position for removal at each operation of the plunger of the brick making machine. In the machine shown four sets of edges Lj, 7c, are represented. It will be understood that this number may be varied to suit the capacity of the machine.

When in operation the mold carrier is rotated in the direction of the arrow shown in Fig. 1, the molds being placed in the sand box at S, and removed therefrom at T. The box is filled with sand to the depth of five or six inches. The faces in, engage witha closed side of the mold and carriesthe latteraround to the position T where it is supported by the face j. The plates H, scoop up the sand and throw it into the mold immediately in the rear and following said plate.

I claim 1. In a mold sanding machine, a rotary mold carrier having heads disposed about their peripheries in co-incident relation a series of faces, some of which extend approximately radially from the carrier, others at Astub- ICO right angles to the radial faces, and others inclining from the said right angularly disposed faces and located between them and the said lateral faces, and sand lifting plates secured to the inclined faces, subtantially as described.

2. In a mold sanding machine, a rotary mold carrier comprising heads mounted upon a shaft and located a distance apart, and having formed in their edges a series of faces, some on radial lines, others at right angles to the radial faces, and some inclining from the relatively disposed faces and located between them and the radialfaces, and sand lifting plates extending across the space between the heads and fixedly secured to the inclined faces and having their advancing edges projectin g beyond the radial faces, substantially as described.

3. The herein specified sand molding machine, composed of a semi-circular casing, ends having grooves on their inner faces to to the shaft, one near each end, and havingv radial faces, seats at right angles to the said faces, and inclined edges between the seats and the said faces, and sand lifting plates secured upon the inclined edges and extending across the space between the spiders, and having their advancing edges projecting beyond the radial faces, substantially as described.

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

ESOM O. LEACI-I.
