BRICK-MOLD SANDER.

SPECIFICATION forming part of Letters Patent No. 469,400, dated February 23, 18592. Application tiled October 1, 1891. Serial No. 407,473. (No model.)

ATo @ZZ whom, it may concern:

Be it known that we, JOHN FARNEN and JOHN MULLOY, citizens of the United States,

- both residing at Chicago,in the county of Cook and State of Illinois, and have invented certain new and useful Improvements in Machines for Sanding Brick-Molds, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is'a central longitudinal vertical section, and Fig. 2 is a vertical cross-section.

Our invention relates to machines for sanding brick-molds preparatory to their being refilled with clay.

The objectof our invention is to provide an improved sanding-machine which will be adapted to be operated in connection with a machine for emptying the molds after they have been lled, such as the machine shown and described in our application iiled May 22, 1891, Serial No. 393,779. l

We accomplish our object as hereinafter specified and as illustrated in the drawings.

That which we regard as new will be pointed out in the claims.

In the drawings, 1 indicates the sander, which is somewhat cylindrical in shape. The

exterior of the sander consists of a thin sheet of metal or other suitable material, which incloses the various parts of the sander. An opening 2 is provided at the upper portion of the sander, which opening is of such size and shape as to permit of the introduction of a mold.

3 and 4 indicate disks of woodorother suitable material, which form the ends of the sander. Upon each end, at the interior of the sander, are formed tianges 5 and 6, which are spirally arranged to form guides for the molds after they have been introduced into the sander. The flanges 5 and 6 are so arranged that as the mold is moved around in the sander it will assume the various positions indicated in Fig. 2 and will finally be carried to the point 7, when it will be ready to be withdrawn from the sander.

8 indicates a shaft, which is mounted cen# trally in the sander and extends longitudinally through it,being journaled in suitable bearings. A sprocket-wheel 9 is mounted upon one end of the shaft, or instead of a sprocket-wheel a pulley may be used.

VMounted upon and keyed to the shaft 8 are wheels 10, which are adapted to be rotated by the rotation of the shaft 8. Each of the wheels 10 is provided with arms 11 and 12, which are at such a distance apart that they will receive a mold between them, as best shown in Fig. 2, and they are of such length that when a mold is placed upon the sander at the opening 2 it will be engaged by one of the arms 12 and moved into the opening 2. We prefer to use two wheels l0, one located `near each end of the sander; but a greater number may be used, if desired. The inner portion of the hub of each wheel l0 is recessed and beveled, as shown at 13 in Fig. 1, anda sleeve 14 is fitted upon the shaft 8 between said hubs, the ends of the sleeve being beveled, so that they will fit snugly into the recesses in the hubs of the wheels 10. By this construction the sand in the sander will be prevented from falling upon the shaft S.

15 indicates an opening in one end of the sander opposite the point 7, through which the molds are withdrawn after being sanded.

16 indicates a carriage, which is adapted to move upon horizontal guides 17, which are suitably supported on'a level with the opening 15 at each side of the carriage.

18 indicates a dog, which is pivotedl to the inner end of the carriage 16 and is provided with an arm 19, which extends at right angles to it.

2O indicatesaspring, which at one end is connected to the arm 19 and at the other toa lug 2l upon the inner end of the'carriagelt, as best shown in Fig. l. The dog 18 is adapt` ed to engage a bar 22 upon the end of a mold 23. All the molds are provided with a rod 22 or some similar device adapted to be seized for the purpose of drawing the mold out of the sander.

The carriage lis connected to a lever 24 by means of a connecting-106125 in such manner that by operating the leverm24 the carriage 16 will be moved back and forth upon the guides 17.

26 indicates a rock-shaft, which is provided with an arm 27, connected to the lever 24 by a connecting-rod 28. By this construction as the shaft 26 is rocked the lever 24. will bereciprocated and the carriage 16 will be moved back and fort-h upon the guides 17.

29 indicates a cogged wheel, which is mounted upon the shaft 26 and is rotated alternately in opposite directions by means of a rack 30. The rack 30 is mounted in suitable guides in such mannerthat it will be adapted to be reciprocated vertically.

3l indicates a rock-shaft, which is mounted in suitable bearings and is connected to the rack 30 by means of a connectingrod 32, which at one end is connected to the rack 30 and at the other end to a crank-arm 33, mounted upon and keyed to the rock-shaft 31.

34 indicates a sleeve, which is mounted upon the shaft 31. The end of the sleeve 34 adjacent to the crank-arm 33 is provided with ratchet-teeth adapted to engage similar teeth upon the inner portion of the crank-arm or upon the shaft, the arrangement being such that as the shaft 3l is rocked the sleeve 34 -Will be intermittently rotated.

35 indicates a sprocketwheel, which is mounted upon the sleeve 3i and is geared to the sprocket-wheel 9 by means of a chain 3G. When a pulley is used instead of the Wheel f), a pulley may also be used instead of the wheel 35, and the two pulleys may then be connected by a belt. Any suitable mechanism may be provided for rocking the lshaft 3l. By this construction when the shaft 3l is rocked the sleeve 34will be made to rotate intermittently and an intermittent rotation imparted to the Wheels l0. The molds in the sander will thereby be moved intermittently around the interior of the sander, and the adjustment of the various parts is such that when the molds arrive at the point 7 opposite the opening l5 the Wheels 10 willremain stationary for asnfficient length of time to permit of the withdrawal of the molds from the sander.

The arrangement of the carriage 16 and dog 18 is such that when a mold 23 arrives at the point 7 in the sander the carriage 1G will move to such position that the dog 18 will engage the bar 22 upon the end of the mold, and the carriage will then be moved outward, drawing the mold out of the sander.

A quantity of sand is placed in the interior of the sander, and the molds are introduced into the sander in an inverted position. As they move to the lower portion of the sander upon the anges 5 and they will take up a` quantity of the sand, which will be scattered.

over theinteriorof the molds as they continue to move around upon the flanges until they again reach the upper part of the sander, When they will be again upturned and the sand will be permitted to fall back into the lower portion of the sander.

In order to prevent the sand which falls out of the molds @from falling into the sanded molds before they are withdrawn from the sander, a deflecting-plate 37 is provided, which extends around the interior of the sander, as shown in Fig. 2. This deflectingplate preferably consists of a continuation of a portion of the exterior covering of the sander. When more than two wheels 10 are used, itwill be necessary to divide the deflector 37 into two or more parts to permit of the rotation of the wheels.

As hereinbet'ore stated, the sander above described is adapted to be used in connection with the machine described in our said former application; but it may also be used alone or in connection with other machines, if desired.
