MOLD-SANDER.

SPECIFICATION forming pat of Letters Patent No.'509,033, dated November 21, 1893.

Application filed April l1, 1893.

^ side of said side plates,-said boxes being .To aZZvwhon/z, it may concern:

Be it known that I, CHARLES H. HoRToN, a

resident of Wel1ington,in the cou ntyof Lorain and State of Ohio, have invented certain new Y tion, such as will enable others skilled in the art-*to which it appertains to make and use the same.

My invention relates to an improvement in mold Sanders-the Object of the invention beingto so construct a sander as to prevent leakage and waste of sand.

A further object is to construct a sander in such manner that it can be easily adjusted to dierent lengths or sizes of molds and so that the molds will be deposited bottom up on a table directly over the box of the sander, whereby the sand jarred from the sanded mold will be made to fallback into the sander where it can be used again.

Afurther object is to so construct a sander that the molds will be sanded on both sides.

A further object is to provide simple and ecient means whereby to automatically stop the mechanism when the machine.

A further object is to provide a mold sanding machine which shall be simple in construction, cheap to manufacture, easy to opthe molds pass out of erate and eectual in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out i-n the claims.

In the accompanying drawings: Figure 1 is vaside view. Fig. 2 is a plan view. Fig. 3 is a sectional view. Figs. 4 and 5 are details.

A, A, represent the side plates or uprights of the machine, which are supported the proper distance apart by means of devices located between them. A sand box B1 is l0- cated between the side plates A, A and preferably curved,-said sand box comprising a -series of plates a, to which a flooring bis secured. Passing through the side plates A, and through the machine approximately concentric with the curved sand box B, is a shaft 0, having its bearings in boxes c on the outserai No. 469.988. (No man.)

side plates A, the latter are provided with elongated slots c2. By mounting the shaft C in the manner above explainedit will be seen that it can read ily be adj usted relatively to the sand box, in order to conform to any desired thickness of mold. Two Wheels D, D, having.

comparatively broad peripheries, are mount-- ed on the shaft Oand adapted to be adjusted and secured at different positions thereon by means of set screws c3.

In proximity to the lower end of the sand box B, a shaft d is mounted in suitable boxes secured to the side plates or standards A, and on this shaft two sprocket wheels d are adj ustably mounted and adapted to align with'the Wheels D.l Near the upper end of the sand box another shaft c is mounted in suitable bearings secured to the side plates or uprights A, and on this shaft two sprocket wheels e are adjustably mounted.

` Behind the sand box B, and preferably about the center thereof, are two shafts f, f, adjustably mounted in perforated bosses projecting from the side plates A, and provided at their inner ends with crank arms f3, at the free ends of which latter spindles f4 are connected and on these spindles sprocket wheels f are mounted. Endless chains g, g, pass about the sprocket wheels d', d', c', c and f, f and, when, no molds are passing through the machine, said chains bear against the peripheries of the wheels D. In order to maintain the chains g, gat the proper tension, the

outer ends 0f the shafts f, f are provided-with arms f5 having weights f6 adj ustably secured thereon.

At the top of the machine a table E is lo-y cated, said table comprising a bar h extending from one plate or standard A tothe other and arms or brackets h', projecting therefrom, and in proximity to said table E, ,a table E is located, between which, tables, the molds are adapted to pass when they come out of the machine. In order to permit boxes of different sizes to pass betweenthe tables E, and E', the ends of the bar h of the table IOO E are provided with ears i having vertical y elongated slots e" and the adjacent side plates or standards A, A, are provided with'horizontal elongated slots 2f-through which slots i', 2, bolts i3 are passed.

At the front of the machine, in proximity to the lower end thereof, a plate F is secured between the uprights or standards A andprovided with horizontal slots j. Arms j are secured to said plate F by means of bolts l7'2 passing through the elongated slots j, in plate F and vertical slotsj3 in the arms and at the upper ends of the arms j slides or guideways la are located,-said slides or guideways being retained in proper positionl relatively to each other by means of a rod lo', which rod is screw threaded at its ends k2 k2 and provided on said ends with jam nuts k3 k3 whereby the rod is adjustably secured at its ends to the arms j preferably in proximity to their upper ends. By thus constructing and arranging the slides or guideways 7c, they may be readily adjusted to conform to molds of different lengths. The table E above referred to is provided with elongated slots Z for the reception of bolts Z whereby said table may be adjusted lengthwise to accommodate itself to a brick machine. Said table E is also provided with a series of elongated slots m, so that any loose sand adhering to molds placed thereon will fall into the sand box B.

A pulley is mounted on the shaft e for the -reception of a strap or belt from any convenient source of power and the hub of said pulley carries `a clutch sleeve n adapted to mesh with a clutch sleeve fn mounted to rotate with the shaft e, but have a sliding movement thereon. The lclutch sleeve n is made with a grooved collar n2 for the reception of the bifurcated end of an operating lever n3, said lever being pivoted at a point between its ends, to a suitable bracket n4, secured to one of the standards A. By operating the lever n3, the mechanism may be quickly thrown out of gear. Mounted at right angles to the shaft e in suitable brackets or bearings o, is a shaft 0, having an arm o2 at one end thereof adapted. to engage the lever n3. The other or inner end of the shaft o is provided with an arm 04 which extends to a point in proximity to the center of the table E and at its free end is bent upwardly between the brackets h of said table,-the free extremity of said arm being provided with a cross bar o5. By the provision of these devices means will be produced whereby to automatically operate the clutch above referred to/and stop the mechanism as each mold passes out of the machine. p

In the operation of the machine, before placing the molds in the slides 7c, the space between the wheels D and the bottom of the sander box is iilled with sand. The mold will pass from the slides to the chains g, and will be carried between said chains and the wheels D through the machine. Thus the molds will be carried edgewise to the body of the sand,-

the-surplus sand rolling over theI edge of the mold or pallet and from that to the next, completely sanding both sides; The mold will be discharged through the space between the tables E, E', being properly guided thereto by means of arms E2 (preferably curved) projecting from the table E.v The mold, after passing through the space between the tables E, E', will fall, bottom side up, on the arms or brackets of the table E and surplus or loose sand adhering thereto will be permitted to fall back injto the sander box B where it can again be used. As the mold falls upon the arms or brackets h of the table E, it will strike the cross head 05 at the end of the arm o4 and depress said arm, thus causing the shaft o to which said arm is secured to oscillate. As the shaft oscillates the arm o2 at the outer end thereof will engage the operating lever n3 and operate the clutch, thus stopping the mechanism. Thus it will be seen that as each mold passes out of the machine, the surplus sand will be returned to the sander box, that the mechanism will be automatically stopped, and that said mechanism will remain at rest as long as the mold is allowed to remain on the table E. As soon as the mold is taken from the table E, the clutch will be again operated to start the machine and the cross bar or head 05 made to assume its normal position ready to be operated byanothermold,by means of a spring o8 secured at one end to the frame of the machine and at the other end adapted to bear on the lever n3. When the inolds are taken from the table E, they will be deposited on the table E (any loose sand falling through the slots in said table) from which they will be transmitted to the brick machine.

My improved sander can be adapted to work on either side of the brick machine by simply changing the shaft e end for end and adjusting the table E to correspond with the distance of the s'ander from the brick machine.

Various slight changes might be made in the details of construction of my invention without departing fromL the spirit thereof or limiting its scope and hence I do not wish to limit myself to the precise details of construction herein set forth; but,
