JAMES BROWN, OF PADUOAH, KENTUCKY.

BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,477, dated September 21, 1886.

Application filed March 9, 1886.

To all whom it may concern:

Be it knownthat I, JAMES W. BROWN, a citizen of the United States, residing at Paducab, in the county of McCracken and State of Kentucky, have invented certain new and useful Improvements in Brick-Machines,of which the following is a-full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speci-' fication, in which- Figure 1 represents a front perspective view of a brick-machine embodying my improvements. Fig. 2 is a longitudinal sectionalview of the same. Fig. 3 is a plan view of the upper cap or transverse plate. Fig. 4 is a detail view showing the movable boxing for the rear transverse shaft. Fig. 5 is a modification, to be hereinafter described. I

My invention relates to reciprocating brickmachines; and the same consists in'the construction and combination of devices hereinafter described and claimed.

To enable others skilled in the art to make and use my invention, I will now describe its construction and indicate the manner in which I have carried it out.

1 In the said drawings,A represents a suitable frame, in which the several operating mechanisms of my press are mounted. This frame A consists, essentially, of two side pieces, be-

. tween which is secured a rectangular or other shaped box, B, forming a chamber, in which the clay is thoroughly mixed, and from which it is discharged, as I shall hereinafter explain. In the construction of this box or mixing chamber I have found it desirable to have one or more of its sides removably secured,whereby the operator may adjust the agitator-arms, or clean the interior of the chamber, or free it of stones or other incompressible substances, should such be found therein. A shaft, 0,

passes vertically through the center of the box, and through a suitable stufling-box, c, and has secured thereon the arm or agitators a, which are designed to engage the mass of clay and thoroughly mix the same, while on the lower end of the shaft and beneath the box is secured a gear-wheel, b, to which power is applied to rotatethe shaft and arms. The sides A of the frame are connected with each other by a transverse cap, D, the central por- Sorial No. 194,544. (No model.)

' tion of .Which is open to permit the free passage of the clay as it leaves the hopper. This cap also furnishes a bearing for an internallyplaced gear-wheel, c, it being confined within the cap by a plate, (1, to which the hopper e is attached. This plate (I is provided with standards f, in which is mounted the shaft 9 of the drum E, around which is passed the apron or carrier F, for delivering. the clay to the hopper. The shaft galso carries a gearwheel, h, which meshes with the gear-wheel c and rotates the same, whereby the plate (I rotates on its central hub and enables the hopper to be turned to any angle, or to adjust itself with relation to the direction of the travel of the apron or carrier. This is an important feature in the construction of a brick -machine, as it permits the receiving end of the apronto be shifted from one point to another without causing a similar change in the position of the machine, as the hopper readily and automatically adjusts itself, so that the belt or apron, will always register with the mouth of the hopper.

To hold the plate 01 to its seat against the cap, I employ small clips, 2 through which set-screws 3 may be passed, as shown.

At the rear of the machine the sides A of the frame are extended and provided with journal-boxes 5 and. 6,:for the transverse driveshaft H, having secured thereon an eccentric, I, to which is attached, by a strap-connection, the pitman K, the forward end of which is attached to and operates the plunger L, as shown in Fig. 2. This plunger L ,reciprocates within a chamber, 7, formed between the bottom plate, 8, of the box B, and a partition, 9, located immediately beneath said bottom, and during the reciprocating movements of the press operates upon the clay as it passes through the opening 10 in the plate 8, and compresses said clay, in the manner I will hereinafter indicate.

Motion is imparted to the several operating mechanisms through a drive-pulley, Z, secured to one end of a transverse shaft, 11, journaled within the sides A. lhis shaft also carries with an idle-gear, 14, on a shaft, m, as shown in Fig. l.

The main shaft H has keyed or otherwise secured to one of its ends a large gear-wheel, M, with which the gear 14 meshes, whereby the power of the pulley Z is transmitted directly to the gear M through the medium of the gears 13 and 14; as before described.

The journal-box 6 adjacent to the gearwheel M comprises a movable box or bearing, a, whereby said shaft may be moved horizontally to disengage the gear M with the gear 14. This important feature is necessary to relieve the press of the great strain that would be brought uponit in the event of some hard incompressible substance finding its way to the chamber 7 during the movements of the plunger, and this feature is accomplished by means of a lever, N, fulcrumed at 15 to a lug, 16, projecting from the frame, as shown in Fig. 1. The lever N is mounted on the shaft H, and extends to the front of the machine, so as to be within easy reach of the operator, who, when he discovers the presence of stones or other hard substances, raises the lever N, which movement causes the box 6 to slide on its guide, carrying with it the shaft H, thereby moving the gear M from its engagement with the gear 14, and checking the further movement of the eccentric I and plunger K.

The sides A at the front of the machine are provided with grooves o, in which vertically slides the shaper P, the upper portions of which are attached by links 17 to the oscillating arms 18, pivoted at or near the center of the frame, as shown in Fig. 1. This shaper P is provided with projecting lugs 19, between which slides a fender, 20, and between these lugs, in the body of the shaper, are formed openings 21, whose configuration is approximately that of a brick, but whose dimensions areslightlyless than the openings in the mold. It will be observed that the lower portion of these openings is provided with knife-edges, the purpose of which is to sever the clay that has been forced into said openings in both shaper and mold by the plunger. By making the openings in the shaper slightly less than those in the mold it is evident the clay is shaped and readily enters said mold without touching the sides of the same. The further movement of the plunger causes the clay to be forced into every portion of the mold and without disturbing the sand therein contained when molding sanded brick. At the rear the arms 18 are connected by links 22 to a verticallysliding frame, 23, having boxes 24 formed thereon, adapted to contain weights,

whereby the shaper is counterbalanced and caused to move upwardly to sever the clay, as I will presently describe. The frame 23 is provided with a projecting lug or lip, 25, and

the shaft H has I mounted thereon a cam-segment, 26, which, during the revolution of said shaft, is designed to engage the lip 25 and raise the frame 23 and boxes 24 upwardly. This movement of the frame 23, through the agency of the arms 18, affects the position of the shaper P, and causes said shaper to descend to permit the clay to be forced through the openings 21 by .the plunger L. As soon as the plunger has completed its forward movement, it will be found the segment has rotated until the point 27 has engaged the end of thelug 25, when a slight onward movement causes the lug to be released from its engagement with the segment, when the weighted frame 23 immediately falls. This movement forces the shaper upward and severs the clay that had previously been forced through the openings 21.

Between the sides and at the lower portion of the frame A is pivotally secured a forked lever or receiver, It, the forward end of which carries a plate, 28, as shown in Figs. 1 and 2. This receiver is preferably a counterbalanced frame, having at its rear an inclined lug or lip, 29, which is engaged by a cam, 30, secured to the segment 26, whereby during the rotation of the segment the cam 30 strikes against the lip 29 and depresses the rear end of the lever or receiver R. The forward end of the lever is now raised, and the pallets which are placed upon the plate 28, and which receive the burned-out bricks, are brought directly beneath the mold after the latter has received the clay and the samehas been compressed. If it be desired to use the ordinary yard molds with bottoms, the front of the receiver may be elevated, when the lug 29 will not be affected by the rotation of the segment.

The mold, S, used in the present instance is provided with openings corresponding with, but slightly larger than, the openings in the shaper, and has projecting ends 30, serving as a shaft by which the mold may be made to describe arcs of circles in receiving and depositing the clay. One end of I the shaft 30 is provided with acrank-arm, 31, having a wristpin projecting therefrom, and to which is attached the forward slotted end of a lever, T,

- fulcrumed upon-a stud, 32, projecting from the frame A. This leverT ishinged or jointed at 1',

while its rear end, s, is weighted and camshaped, and is designed to be engaged by a pin, i, projecting from the gear-wheel M, whereby when said pin engages the cam-shaped ends it raises said end. At the same time the forward end is depressed and the mold forced from a vertical to a horizontal position upon the plate 28 or interposed pallet. The rear end of theleverTis provided with a spring, a, the free end of which bears against the lever in front ofits hinge-joint. This spring forms a yielding connection between the two parts of the lever, and permits the cam-shaped end to be raised by the pin without straining the lever should there be any obstruction or derangement to the several parts of the machine, such as a rock in the shaper, 85c.

' In Fig. 5 is illustrated a mold-case which is designed to receive a wooden mold-frame for holding sanded brick.

The operation of the machine is substantially as follows: The clay from the bank is delivered on the carrier F and deposited in the mixing-chamber through the hopper. From thence it passes into the chamber 7. where it is operated upon by the plunger. The shaper is then caused to descend by the segment 26 and lip until its openings align themselves with the openings in the mold, the clay being forced through the openings 21 into the mold. The lever T, nowbeing operated upon by the pin, forces the mold downward upon the pallet placed to receive the bricks, the receiver or lever B having in the meantime raised the plate 28 and pallet upward, so that the mold will find a seat upon the plate or its pallet.

By means of the construction herein de scribed I am enabled to provide a compact substantial machine, and one in which the power applied to the several mechanisms is rendered more effective than in many of the machines now in use for similar purposes.
