BRICK-RE-PRESSING MACHINE.

Specification of Letters Patent.

I Application filed August 6, 1917. Serial No. 184,6?4.

To all whom it may concern:

Be it known that T, DANIEL cross, a citizen of the United States, residing at Elmhurst. in the county of Queens and State of New York, have invented ,certain new and useful Improvements in Brick-Re-Pressing Machines, of which the following is a specification.

This invention relates to a machine for repressing bricks. Such machines are of course in use as it is common practice to repress bricks. But all devices of this character that I have knowledge of are located in a fixed position, the pallets are taken from the drying racks, loaded upon a truck, moved to the repressing machine and the bricks then lifted by hand from the pallets and placed in the molds, then after being repressed they are removed by hand, replaced on the pallets and wheeled back to the racks.

My invention is designed to save as much of the time and labor involved in this operation as possible.

The invention consists in a repressing machine mounted upon a movable frame which is adapted to travel along a track between the dryingracks, being stopped at any suitable place. The pallets, with from six to ten bricks thereon, are placed on the machine, the pallets are automatically advanced to the molds, all of the bricks on the pallet removed at one time and placed automatically in the molds. and the pallet then lifted upwardly and transferred by a suitabie conveyer to the opposite side of the molds, and the repressed bricks delivered to it. The pallet with the repressed bricks is then moved to the front of the machine,

and lifted therefrom by hand and replaced in the racks. The only hand operation emploved is the lifting of the pallets from the racks to the machine and from the machine back to the'racks.

The invention also consists in the novel features of construction hereinafter described, pointed out in the claims. and shown in the accompanying drawings in which Figure 1 is aside elevation, parts being broken away.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Fig. 3 is an end elevation.

Fig. 4 is a side elevation, partly in section, and showing details of a carriage, and carriage releasing and moving devices.

Fig. 5 is a section on the line 5-5 of Fig. 4..

Fig. 6 1s a section on the line 6 dof some of these features, as they would, if included, hide parts that relate directly to the invention, would confuse the drawin s, and would of themselves add nothing to the disclosure. This relates especially to the motor power employed, and the means for transmitting power from one part to another, either by belts, chains or gears. The device as a whole is intended to be operated by either an electric motor or a gasolene engine. If with motor it will be supplied with current from an overhead trolley. If by gasolene engine n'o wires will be required. It is obvious that neither the electric motor, the trolley, .or the engine form a part of the invention, and they are therefore not The table 1s practically an open frame and at its rear end portion are transverse shafts 6 provided with wheels 7, on each side of the table, and belts 8.

At the forward end are similar wheels 11,

shafts 10 and belts 12. The

belts

8 and 12 form conveyers at the rear and front of the tables respectively.

In the offset portion of the table are molds 13 provided with lower plungers 1d which work in the molds, and the molds are separated by vertical partitions 15. These partitions extend above the mold tops and ried by a frame 22, and actuated by a rod 23. 'in the usual manner, which rod may be operated in any manner from shaft 18, as by an eccentric 23 The use of'the lower and upper plungers in brick pressing machines is not claimed as new.

When the bricks are placed in the racks they are held on pallets 24. These pallets are of greater length than the width of the table. They usually hold from six to ten bricks, and there will be as many molds and plungers in both upper and lower sets as there are bricks on the pallets. In the draw-.

ings I have illustrated a machine having six of the molds and designed to work with pallets each of which holds six bricks. But

the number is not material.

' When the pallets are lifted from the rack they are placed one'at a time transversely across the belts 8, and are conveyed by the belts to the ofi'set portion 5 which acts as Thisofi'set is just a stop for the pallets.

- equal to the thickness of the pallets so that p in the mold will be pushed forwardly onto ployed:

the bricks 25 will move smoothly from said pallets to the molds. To automatically accomplish this movement I employ a grooved carriage frame 26 in which reciprocates a carriage 27 in the form of a rectangular frame, so the upper plungers can work through it. Within the frame forming the carriage are pivoted brick pushing leaves 28 the swinging movement of which rearwardly is limited by stops 29, these leaves depending sufficiently to engage the bricks but to clear the tops of the mold partitions. At each for-. ward movement of the carriage all the bricks a pallet on the forwardconveyer belts 12,. and a new lot of bricks will be pushed into the molds from a pallet on the rear conveyer belts 8. During rear movement of the carriage the leaves will drag freely over the brick Toprovide for passing the pallets around the molds the following mechanism is em- Cog chain wheels 30 which may mesh with thegears 19 on shaft 18, orin case said shaft is driven by pulley and belt, with suitable gears replacing gears 19,'drive chains 32 running over idlers 31, four of which are carried by an overhead bracket by the frame 22.

There are two of these chains, one on with the stop 47 the 33 supported each side of the'table and they carry small pivoted hangers or lifts 34, mounted to hang to the belts 12, where it will be disengaged.

They are so timed and spaced that they will take a pallet from the rear conveyer just after the carriage has cleared it of bricks,

and will deposit a pallet on; the front conveyer in time to receivea new supply of repressed bricks.

' The. means for operating the carriage is one of the essential features of my invenf tion. A shaft 35 with pulley 36' driven by a belt 37, from shaft 18 has. on each end portion a loose Wheel 38, grooved for a cable,

and a keyed wheel 39. As these parts are duplicated on each side of the table,a de-- scription of the mechanism on one side will be sufficient.

A cam block 40 is secured to the. periphery of the wheel 39, and a pin 41 is secured on the periphery of the grooved wheel 38, which is of less diameter than the wheel 39. On the keyed wheel 39 is placed a spring pressed pin 42 1 which works through a laterally extending bracket 43 carried by the keyed Wheel. presses this pin radially outwardly so that it would clear the pin 4 1. Buta curved metal arm 44 is fastened to the underside of the table and incloses about one half of the periphery of the loose wheel 38. v

A cable 38 is secured to the periphery of the wheel 38 working in the groove, and runs over a guide wheel 45 to a block 46 carried by the rear end of the carriage.

To this block is also connected a catch 47 pivoted to the lower end of the block, so that on forward movement of the carriage it will ride over and lock against a stop 47 Thespring normally on the offset portion of the table. The carriage is released by the lifting of said catch by a pin or rod 47 This rod is normally pressed downwardly by a coil spring 48', the rod being carried by a pivoted bracket 49 which has an arm 50 extending into the path of the block'40.

Itwill be obvious from this description and the drawings that during rotation of the wheel 39 the pin 42 will be brought under the curved portion of the iron arm 44 and be forced down or inwardly so as to engage the pin 41 on wheel 38. This rotates the wheel 38 and winds the cable 38 partly thereon" drawing the carriage forward and as it looks by engagement of the catch 47 pin 42 passes out from under the arm 44 and rotation of the wheel 38 stops.

The carnage remains locked against rear sesame movement until cam block 40 engages the the weight 53.

To prevent a pallet being pushed or pulled from under the bricks during reloading stop pins 54: carried by pivoted brackets 55 are employed. These brackets may be tripped at the proper time in any desired I manner, as by having their rear. ends extend into the path of the cams on the shaft 18, or they can be engaged and tripped by the hangers carried by the chains 32. After a reloaded pallet has been conveyed to the front end of the table it is removed by hand and replaced in the drying racks.

I have omitted such details of power transmission in order not to cover up and obscure features of the invention, as the arrangement of gear and belts etc. are simply matters of mechanical detail and are not considered as involving invention, or as forming any part of my actual invention.

I do not therefore desire to be limited to any particular'means of moving the truck or platform 2 along the track, or of operating the plungers or drivmg the conveyers, all of this transmission mechanism being old and well known.
