SPECIFICATION forming part of Letters Patent No. 768,316, dated August 23, 1904.

Application filed June 6, 1908. Serial No. 160,820. (No model.) i

,To all whom it may concern:

Be it known that we, HERBERT H. SMITH and FRANK B. DUNN, citizens ofthe United States, and residents of Oonneaut, Ashtabula county, and State of Ohio, have invented a-new and useful Improvement in Brick Facing Machines, of which the following is a specification, the principle of the invention being here in explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates to a device for facing one surface of a brick-that is, removing a portion of one brick-surface in order to impart thereto what is commonly known as a rock-face.

The object of the invention is to efliect such an operation automatically by means of machinery and in an economical and efficient manner.

Said invention consists of means hereinafter fully described, and particularly set forth in the claims.

p The annexed drawings and the following description set forth in detail certain means embodying the invention, thedisclosed means, however, constituting but one of various forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a plan' view of a device embodying our invention, a part of the base plate being broken away. Fig. II represents a vertical axial section of a portion of said machine, taken upon a plane indicated by line 2 2, Fig. I. Fig. III representsavertical axial section of a portion of said machine, taken upon the'plane indicated by line 3 3, Fig. I.. Fig. IV represents the bottom plan view of the gear-ring forminga part of such machine. Figs. V, VI, VII, and VIII represent vertical sections taken upon the planes indicated by the lines 5 5, 6 6, 7 7 and 8 8, Fig. IV, respectively. Fig. IX represents in perspective a portion of said device with parts removed, the base-plate being shown broken away.

Upon the base-plate A is formed, by means means of suitable .drivingpulleys.

hearing, which receives the lower end of a rotatable ring B, Fig. IX. This ring is formed upon its outer lateral surface with teeth 6, which mesh with the worm O, secured upon the rotatable shaft 0, mounted in suitable bearings upon the base-plate A and rotatedNby ot It will be seen that the rotation of the shaft and worm will effect a rotation of the ring B.

Formed or secured upon the base-plate are a series of blocks (0 Fig. IX, provided with suitable grooves forming slideways for parts reciprocable toward and from the center of the base-plate, aswill be further described. Such center of the base-plate is formed with an opening a of a rectangular cross-section, as

shown,-and of dimensions such as will permit a brick to fall or drop therethrough. In these slideways are located two clamping-blocks D, Figs- II and III, which are reciprocable toward and from the center of the base-plate.

"Upon the top of each such block and having a sliding bearing thereon is a knife E, which is secured to a reciprocable block E and adjustable relatively thereto by means of set-screws and e, as shown in Figs. 'I and II. These blocks E are held in position by means of gib-plates a as shown in Fig. I. It will be seen that the clamping-blocks and knives may be'reciprocated toward and from the center independently of each other. Recipro'cable at right angles to the knives E are two knives E mounted in bearings formed in the blocks a and held down by means of the gib-plates a, Fig. I. These knives are secured to the space, four slides F, Figs. -I, II, and IX, are

provided, which are also reciprocable toward and from the center of the plate. These slides may be caused to project into the path of the brick and intercept same, so as to hold it in the brick-receiving space.

Each block E and E is provided at its rear end with a downwardly-projecting pin w, the blocks 1) being provided with upwardly-projecting pins v these pins being located in the same vertical plane. The inner-face of the gear-ring B is provided with a series of inwardly-projecting lugs provided with camsurfaces, as will be hereinafter described. These lugs are located in two series, the members of each series 7f 1; 7) If I If I)" 7) being separated from each other by an angle of ninety degrees, as shown in Fig. IV. The series .5 &c., consists of four pairs of lugs, each pair comprising an upper and lower lug, as shown in Fig. IX. The upper lug is provided with a concave inclined face forming an inclined plane which is adapted to contact the outer ends of the sliding blocks E and cause the same to be moved inwardly toward the center of the base-plate, when contact between such face and such inner ends is effected. The lower lug of each such pair is formed with a similar concave face, but of a greater length than that of the upper, and is adapted similarly to engage the outer ends of the blocks D. The construction is hence such that the rotation of the ring in the direction of the arrow in Fig. I will effect a simultaneous inward movement of the blocks 1) and then a subsequent simultaneous inward movement of the blocks E and the knives E and E Each of the lugs of the series If is formed with the upper and lower cam-grooves (1" and 6, respectively, such upper and lower grooves being identical in form and located in vertical planes. The forward end of these camg rooves is enlarged, so as to engage the pins c and a. knives are in their forward position, the construction being such as to cause these blocks and knives to be withdrawn simultaneously after having been acted upon by the cam-surfaces of the series of lugs 7f, &c., as will be readily understood. It will hence be seen that the rotation of the ring will effect first the simultaneous movement of the clampingblocks, then the subsequent simultaneous movement of the four knives, causing the latter to intersect the brick-receiving space, and then a simultaneous withdrawal of all the knives and clamping-blocks.

The rear or outer ends of the slides F are each provided with an upwardly-projecting lug f, which is engaged by the cam-groove 6, formed upon the bottom of the ring B, as shown in Figs. 11 and IV. This groove is formed with four cam portions 6 which are located at an angular distance from each other of ninety degrees, as shown in Fig. 1V, and effect a simultaneous forward and rearward movementof the slides. This motion of the When mounted, the blocks andslides is timed so as to take place immediately following the inauguration of the rearward movementor the withdrawal of the blochsalul knives, the forward movement of the slides immediately preceding the forward or inward movement of the clamping-blocks.

The working face of each clamping-block is formed upon a separate plate which is separated from the main portion of theblock by means of a rubber plate d, and upon the middle working face of such working plate is secured a projecting spring d. which may be depressed into a countersunk portion or seatd. As shown in Fig. IX, we prefer to form the slides F in one piece, having a common upwardly-projecting lugf, such construction contributing to the simplicity of the device.

The space intermediate of the knives, the clamping-blocks, and the bars F, and the discharging-opening (1 forms a path of travel for bricks, the latter being caused to traverse such path preferably by gravity.

The operation of the above-described device is as follows: Assuming that the blocks and knives are in their withdrawn positions and that slides F are in their forward or in tercepting positions and that a brick is in said space and intercepted and held therein by means of said slides F, the spring guiding and centering same in such space, the ring B is continuously rotated, the clamping-blocks are now moved forward and caused to securely clamp and hold the brick in the space awaiting the approach and operation of the knives. During such action of the clampingblocks the guiding-springs(15 are depressed into their seats (5", and the elastic rubber plate (Z' prevents the crushing of the brick, at the same time permitting a lirm holding thereof. The cutting knives now advance and intersect the brick-space, chipping the upper sur face of such brick on all four sides, thereby effecting the desired result. The continued rotation of the ring B now cli'ects a simultaneous withdrawal of the knives and clamping-blocks, which is inn'nediately followed by the withdrawal of the slides F, which permit the discharge of brick from the opening 4 Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

It will hence be seen that the bricks are first arrested, then clamped in their path of travel, the cutting operation performed, and the bricks then discharged, these operations bcing performed automatically and successively in successive planes.

\Ve therefore particularly point out and distinctly claim as our invention-- 1. In a brick-facing machine, the combination of automatically-operating brick-arresting, brick-clamping, brick-cutting, and brickdischarging means.

2. In a brick-facing machine, the combination with automatically-operating clamping means forminga brick-receiving space, of two sets of automatically-operating cutting knives respectively located upon opposite sides of a brick while in such space.

- 3. In a brick-facing machine, the combination of brick-arresting, brick-clamping and brick-cutting means arranged to coact and means for actuating such means successively and automatically.

4:. In a brick-facing machine, the combination of reciprocable clamping means forming a brick-receiving space, 'reciprocable means below said space and arranged to intercept a brick while located therein, reciprocable cutting means arranged to intersect the latter and means for actuating said intercepting, clamping and cutting means consecutively.

5. In a brick-facing machine, the combination of reciprocable clamping means forming a brick-receiving space, reciprocabl'e means below said space and arranged to intercept a brick while located therein, reciprocable cutting means arranged to intersect the latter, and continuously rotatable means for actuating'said' intercepting, clamping and cutting means consecutively and intermittently. v
