BRICK-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 776,820, dated December 6, 1904. Application filed May 21, 1904. Serial No. 209,078. (No model.)

To all whmn it may concern:

Be it known that I, IsAAo V. VVoLirn, a citizen of the United States of America, residing at Johnetta, in the county of Armstrong and State of Pennsylvania, have invented. certain new and useful Improvements in Brick-Pressing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to brick-pressing machines, and has for its object the provision of novel means whereby bricks may be pressed and stamped as rapidly as the same are fed to the machine.

Another object of my invention is to provide a machine of this character wherein the bricks are automatically handled by the 1uachine, pressed and stamped, and delivered to a suitable conveyer, from where they are carried to the kilns.

My improved machine is particularly adapted for use where the bricks are wire-cutthat is, the two flat surfaces of the brick are rough and are to be compressed to form, the sides of the brick of the same smoothness as the ends and edges of said brick, and in con structing my improved machine I have provided novel means whereby the bricksmay be removed automatically from the conveyor to said machine, where they are pressed and stamped, if desired, and I have provided novel means for removing the bricks therefrom and placingthe same in a position where they may be received by the hatchers, or men who place the same in the kiln for burning, or the bricks may be passed onto a suitable conveyer which terminates in the vicinity of the kilns. Heretofore in machines of this type it has been impossible to stamp and com press the bricks in one operation, and in connection with this operation 1 have provided novel means in connection with the machine whereby the manipulating of the bricks is continuous during the operation of the machine. All of the above construction employed to accomplish these results will be hereinafter more fully described, and in the drawings accompanying this application like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a top plan view of my improved machine constructed in accordance with my invention Fig. 2 is a side elevation of said machine. Fig. 3 1s a vertical sectional view of the reciprocating compressing-arm. Fig. at is a detail perspective view of one of the dies mounted in the compressing-block, and Fig. 5 is a horizontal sectional view taken on the line 5 5 of Fig. 2.

Referring to the drawings accompanying this application, the reference-numeral 1 indicates a base upon which my improved machine is constructed, although the machine may be readily constructed upon a suitable foundation which will support said machine and be advantageous to the general operation of the same. Upon this base 1 is constructed a framework, which consists of the standards 2 2 and the eross-beam 3. Upon this cross-beam is mounted a main operating-shaft 4, which is journaled in the bearings 5 5, carried by the cross-beam 3, and upon the outer end of the shaft 4: is keyed a pulley 6. while on the other end of the shaft is a pinion 7.

The reference-numeral 8 indicates a clutch of the ordinary construction which is adapted to be actuated by a lever 9, this clutch being used when it is desired to throw the machine in or out of operation.

Between the cross-beam 3 and the base of the machine is journaled a vertical shaft 10, said shaft being mounted centrally upon the base, "and upon the upper end of said shaft, which protrudes through the cross-beam 3, is secured a wheel 11, having teeth 12 upon its upper edge which are adapted to mesh with the pinion 7 of the operating-shaft t. Di rectly beneath the cross-beam 3 and upon the vertical shaft 10 is mounted a gear-wheel 1a, and carried by this shaft is a circular table 15, upon which the bricks are compressed and stamped. This table has mounted thereon a plurality of compressing-arms, and in the accompanying drawings 1 have shown six of thesecompressing-arms, said arms being operated independently of the table 15, and the being beveled, as indicated at 17, the object of which will be hereinafter more fully described. These enlarged portions 16 are provided with the vertical apertures 18 and 19, said apertures extending through the table -of the machine, and in the aperture 18 is mounted the vertical reciprocating compressing-block 20, in the lower end of which is journaled a wheel 21, and when the table 15 is rotated this wheel travels upon a circular cam-path 22, whereby at predetermined points the compressing-block will be reciprocated vertically within the aperture 18 of the enlarged portion 16 and the table 15. In the upper end of this block is adapted to be secured a die 23 by any suitable means, that shown in the drawings comprising a screw 24, and this die is employed for stamping the trade name or mark upon the one side of the brick when the same is being compressed by said block.

The reference-numeral 25 indicates an L- shaped compressing-arm which is carried in the aperture 19. The compressing arm is shown in detail in Fig. 3 of the drawings, and the horizontal arm of the same extends over the aperture 18, in which the bricks are pressed, so that the bricks during the operation of pressing the same lie between the die 23 on the upper end of the compressing-block 20 and the lower side of the lateral arm 28 of thecompressing-arm, and the lower end of this arm is adapted to engage the inclined surfaces 26 26 of the blocks 27 27, which are mounted upon the base of the machine within the campath 22, whereby during the rotation of the table 15 the ends of these arms will strike said blocks and be reciprocated within the aperture 19 of the table. In the lateral portion 28 of said arm is adapted to be mounted a die 29 by means of a bolt and nut 30, this die being similar to the die 23 of the compressing-block and having thereon a trade name or mark similar to the die 23.

The reference-numeral 31 indicates standards, which are mounted upon the side of the machine at a right angle to the cross-beam 2, and these standards support a table 32 and an inwardly-extending arm 33, and upon this table 32 are carried the bricks to be compressed, from where they are ejected upon the table 15.

The reference-numeral. 34 indicates a conveying-belt commonly used, the upper layer of this belt passing through a groove 35, formed in the top surface of the table 32, and the belt passes around the pulley36, mounted in brackets 37, carried by the edge of the table. The ejector mechanism of said table consists of a block 38, which is slidably mounted bel tween the guide 39 and the standard 31. This block is actuated laterally upon the table 32 by a depending arm 40 of a shaft 41, which is journalcd in a bearing 42 upon the top of the inwardly-extending arm 33. This depending arm 40 is bifurcated, as indicated by the reference-numeral 43, and is adapted to engage over a pin 44, carried by the block 38. The other end of the shaft 41 carries a downwardly-extending arm 45, to which is pivotally connected a link 46, which is adjustable by a turnbuckle 47, the outer end 48 of said link being pivotal] y mounted upon a pin 49, carried by a rod 50, which extends through the standard 31 and has connected to its other end, as indicated at 51, a link 52, which in shaft 54, mounted in the inwardly-extending arm 33, and upon the upper end of this shaft is secured a pinion 55, which is adapted to mesh with the pinion 14, carried by the vertical-shaft 10 of the machine.

The reference-numeral 56 indicates an anglearm which is secured to the inner end of the table 32, the horizontal portion of said anglearm being adapted to extend over the table 15 of the machine.

To facilitate the downward pressure of the vertical reciprocating compressing-arm 25, I have secured a depending arm 57 to the crossbeam 3, and upon the lower end of this arm I mount the segment-shaped cam-plate 58, which is adapted to engage the top edge of the arm 25 when the table 15 rotates and depresses the same.

The reference-numeral 59 indicates a vertical standard, which is mounted upon the base 1, said standard being arranged in front of the table 32, and the bracket 60 of said standard is adapted to project over the belt 34, as shown in Figs. 1 and 2 of the drawings, and in said bracket is journaled a roller 61, this roller being adapted to strike the edge of the bricks 62, whizh are resting upon their edges upon the belt 34, and this roller upon striking said brick turns the brick, whereby it lies upon its side and passes under said roller 00 the ejector mechanism of the table.

To remove the brick from the table after the same has been pressed and stamped, I employ a mechanism which consists of a vertical standard 63, carrying a table 64, this table having secured to its inner end an angle-arm 65, similar to the arm 56, heretofore described, and the horizontal portion of this arm is adapted to project over the table 15 to facilitate the removing of the brick therefrom. Upon the table 64 I mount a hookshaped arm 66, which is provided with slots 67 through which the guides 68 68 project, and this arm carries an outwardly-extending pin 69, over which is secured the bifurcated end 70 of the lever 71, which is pivoted, as indicated at 72, to the standard 63. Adjacent to the standard 63 is mounted a block 7 3, upon turn is connected to a crank 53 of a vertical which is pivoted an arm 74-, the one end of said arm carrying a roller 75, while the other end. of said arm has a spring 76 attached toit, the other end of said spring being secured to an angular bracket 77, carried by the block 73. The reference-numeral 76 indicates a link the one end of which is pivotally connected to the lever 7 4:, while the other end of said link is pivotally connected to the pivoted arm 71.

The reference-muneral 80 indicates a lubricator which is carried by an inwardly-extending arm 33 of the machine, whereby as the bricks are carried to the table 32 oil or a suitable lubricating liquid will drop upon the surface of the bricks and further facilitate the pressing and stamping of the same.

The operation of my improved stamping and pressing machine is as follows: In the machine just described it will be apparent from the construction of the same that only two sides of the brick are to'be pressed, and, as heretofore stated, these sides are the ones which have been wire-cut, leaving a rough and ragged surface upon the brick. Upon these wire-cut bricks having been placed upon the belt 34: they are conveyed to the table of the machine, the roller 61 having turned the same in the position in which they are to be placed upon the revolvingtable 15. Upon the bricks reaching the table 32 they are ejected therefrom by the block 38, which is actuated by the arm L0, which is reciprocated back and forth by the rod 50 through the medium of the crank 45 and the link 46, this rod 50 being actuated by the crank-arm 53 of the vertical shaft 54 through the medium of the link 52 and the shaft 54, and motion is imparted to it by the pinion 55, meshing with the pinion let. The movement of the rotary table and of the block 08 is so timed that each brick as it is ejected from the table 32 lodges in one of the apertures 18, and the movement of the conveyer-belt 34 is also so timed that a brick will always be in position in front of the ejector mechanism when the latter is in position to push the brick off the table 32 onto the rotary table 15 and between the compressing-block and the compressing-arm which at that time is in alinement with the ejecting mechanism of the table 32. The bricks do not need to be spaced regularly upon the conveyer, for the reason that each brick as it is fed along by the conveyer comes in contact with the guide 39 and is prevented from further movement in the direction of movement of the conveyer by said guide, and this guide is so positioned, as shown in Fig. 1, that when a brick rests upon the table against the guide it will then be in front of the ejector-block 38. The driving power of the machine is applied at pulley 6, and upon the clutch being in a closed position a rotary movement will be imparted to the wheel 11, which revolves the vertical shaft 10 and operates the ejector mechanism carried by the-table 32. When the mechanism is operated, the brick to be compressed is ejected onto the angle-arm 56, and simultaneously with this movement the rotary table revolves and a vertical reciprocatory movement is imparted to the compressing arm and block. As the table revolves the block 79 strikes the brick which rests upon the angle-arm 56 and carries the same around with the table. At this time the compressingblock is lowered by the wheel 21 traveling down the incline of the cam-path, and the compressing-arm is in a raised position, owing to the lower end of the same engaging the top edge of the blocks 27, and upon a further rotation of the table 15 the compressing-arm engages the flat surface of the brick, and when the same passes under the cam-plate the flat surfaces of the brick are compressed, and as the table revolves the compressing-arm is raised by the lower end of the same riding up the incline 26 of the blocks 27 and the compressing-block is raised by the wheel 21 traveling the cam-surface 22 of the cam'path, and as the enlarged portion 16 of the table reaches a point adjacent to the standard 62, the beveled faces 17 of the enlarged portion 16 strike the roller 7 5 of the arm 74, forcing the same outwardly, which throws the pivoted lever 71 outwardly, carrying with it the hook-shaped arm 66, which carries the brick upon the angle-arm and thence onto the table ca,

from where a suitable conveyer may carry the same to a point in the vicinity of the kilns, or the hatchers may carry the same to the kiln in which the bricks are to be hatched and then burned.

It will be observed from the general construction of my improved machine that the bricks as the same are fed thereto may be quickly manipulated and that a greater amount of work can be accomplished than by machines heretofore constructed, and while I,

have herein shown mechanisms for accomplishing the desired results it is obvious that the details of c0nstruetion---such as the general arrangement of the cam-paths, the number of compressing arms and blocks used, and other slight changes may be made without departing from the scope of the invention.
