To all whom, it may concern: E 'E re resent endless sprocketchains Be it known that I, CHARLES H. HORTON, of which are guided by idlersprocketwheels e, e, Painesville, Ohio, have invented certain new 6 and 6 respectively. Two of the sprocketand useful Improvements in Mold-Sanding wheels, 6 e, are mounted on a shaft or spindle Machines; and I do hereby declare the fol- F, and two, e and a are mounted on ashaft G.

A similar device (not shown in the crs skilledin the art to which it pertains to drawings) is located on the opposite side of make and use the same. the machine for tightening the chain E. The

The curvature of the surface of these lugs is S represents a two-part adjustable hopper such as to enable them to readily pass under and guide adapted to receive, hold, and guide a mold when it is lying on the wheels. When the molds and in connection with wheels B the machine is operated, the lugs pass under and O to feed the molds one after the other 0 the upper end of the mold as they lie on the to the machine. The hopper S, as herein- 0 wheels, tipping them at an angle which enbefore set forth, is composed of two parts, ables them to slide into the opening at the each of which is adj ustably secured to an intopof the sand-box.

inclined bracket Z, mounted on said standard, a depending curved flange or guide 1*, and a flange Z, forming a continuous side piece for both the bracket Z and the guide Z The molds are placed in the hopper S with their faces downward. The flanges Z are curved to conform to the curvature of wheels B and O and are located so as to allow of the free passage of the molds K betweenthem and the wheels B and O, as illustrated in Fig. I, and act to guide the said molds-to chains E and E and between same and the wheels B and O.

M and M represent two rollers mounted upon a shaft n, which has its bearings near the top of each of the standards L and L. This shaft n, is adjustable in its bearings by means of a thumb-screw n. By adjusting the shaft 72 the rollers M and M are made to project more or less beyond the surface of the hopper S. The axial line of the rollers M and M is slightly lower than the peripheries of the wheels B and O, and the said rollers are so adjusted that their peripheries project slightly beyond the interior of the hopper, as illustrated more clearly in Fig. V. The function of rollers M and M is to avoid frictional contact between the side of molds K and the angular portion m of the hoppers S and allow of the molds dropping at this side either of their own gravity or by reason of being started by cams or projections 19 b. It will be noticed that the cams or projections I) Z) on wheels 13 O are of such a construction that while they act against the sides of the molds as starters and tilters to lift the inner ends of the same still it is impossible for the said cams to jam or cramp the molds against the hopper S, inasmuch as they will slide or ride under the molds if the molds are not started or dropped to feeding position.

In operation the molds K are stacked in the hopper S so that their open faces will be downward, as illustrated in Fig. I. The wheels 13 and O in revolving cause the cams Z7 Z) to engage the molds and act as starters to feed them between the said wheels and the lower part of the hopper S and are caught and carried by the chains E E and between them and the wheels B and O and carried through the sand-box,where they are thoroughly sanded, and from thence they are carried upward around said wheels 13 and O and delivered in any desired manner.

While I have set forth certain details of construction which I consider best adapted to perform their several functions when properly assembled, I do not desire to be limited to the same, inasmuch as certain of these may be modified.

What I claim is- 1. In a mold-sanding machine, the combination with the casing and mechanism therein, of a hopper located in proximity to said casing, said hopper comprising two vertical standards longitudinally adjustable upon an inclined plate located at the base of the said casing and at the rear end thereof, an inclined bracket mounted upon the top of each standard, a curved guide depending from the top of each standard below the said bracket, an adjustable shaft extending horizontally between the said standards and having its bearing in the respective standards in proximity to the lower end of each bracket, and rollers located upon the said shaft, substantially as described, for the purpose set forth.

2. In a mold-sanding machine, the combination of a casing, an inclined plate located at the base of the said casing at the rear end thereof,two vertical standards adjustable horizontally on said plate, brackets supported by and rigidly secured to said standards, curved guides secured to and depending from said standards, and two adjustable rollers mounted on a shaft supported by the said standard in proximity to the lower ends of the said brackets, substantially as described, for the purpose set forth.

3. In a mold-sanding machine, the combi* nation with a casing, and a hopper located at one end of said casing, of wheels mounted in said casing, said wheels having, on their peripheries, curved-faced lugs adapted to pass under and tilt the mold into position for entering the casing, substantially as described, for the purpose set forth.

Signed by me at Painesville, Ohio, this 18th day of November, 1898.

CHARLES II. HORTON.
