BRICK-VENEERING Macrame.

Specification of Letters Patent. Patented Sept. 9, 1919.

Application filed July 27, 1917. Serial No. 183,070.

To all whom it may concern:

Be it known that I, JOHN ELDRI GE, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Brick-Veneer ing Machines, of which the following 1s a Specification.

This invention is an improved brick veneering machine for glazing, enameling, or surface coating bricks with plastic material.

One of the objects of the invention is to provide a machine capable of rapidly applying the desired coating. A further object is to provide means for doing this uniformly, delivering the bricks evenly coated with clean, sharp edges on the veneer.

The invention will be hereinafter fully set forth, anl particularly pointed out in the claims.

In the accompanying drawings 2 Figure 1 is a vertical side view of my improved brick veneering machine. Fig. 2 is a view similar to Fig. 1 with the framework removed, parts of the machine being in section and parts being broken away; Fig. 3 is a front end elevation. Fig. 4 is a vertical section on the lines 4:--l of Fig. 2. Fig. 5 is a rear end elevation. Fig. 6 is a section of a reservoir showing an actuator and means for operating same. Fig. 7 is a section showing a modified form of the lower portion of reservoir shown in Fig. 6. Fig. 8 is a sectional view of a feed mechanism. Fig. 9 is a detail of a link carriage. Fig. 10 is an end view of same. Fig. 11 is a reverse end view of Fig. 10. Fig. 12 is a section of same on line 121-2 of Fig. 11. Fig. 13 is a perspective front view of a carriage casting. Fi 14 is a rear perspective view of same. Fig. 15 is a perspective view of an edger plate. a

Referring to the drawings, the fourvertical corner posts of a framework, composed of channel iron, are designated at 1. Bolted to the tops of said corner posts and connecting same are two side braces 2,- also of channel iron, and at a distance slightly above the center of the corner posts 1, are secured on either side of the framework longitudinally extending channel irons 3. The said side channels 3 serve as additional braces to the framework and also act as a carriage for various working parts hereinafter described. The said side channels eX- tcnd a considerable distance beyond. the

length of the top side braces 2, to form supports or carriages respectively for feed and delivery into and from the machine.

The channels 3 are braced to the corner posts 1 by oblique braces 4; The two sides of the frames are joined by a yoke 6 at one endand by a yoke 7 at the opposite end.

At a point near the middle of the length i of the channel irons 3, and secured to the upper edges thereof, are bearings 8, in which rotates a shaft 9, driven by a pulley 11, belted or otherwise connected to any suitable source of power. Keyed to said shaft, as shown at 12, is a pinion 13, meshing with and imparting motion to a gear 1 1, keyed to a shaft 1 6, as shown at 17. Extending outwardly from the said gear 14, is a stud shaft 18, on which is pivoted one end of a connecting rod 19, the other end of which is pivotally connected to one end of a rocker arm 21, pivoted near its center on a shaft 22, rotatably mounted in bearings 23, secured to the upper edge of channels 3. Keyed to the shaft 22 as shown at 24 is a ratchet wheel 26, having teeth actuated by a pivoted pawl 27, carried by the upper end of the rocker arm 21, six teeth being shown. Also keyed to said shaft 22 is a pair of sprocket wheels 28. The purpose of this construction is to impart an intermittent motion to the sprockets 28, from the con tinuous rotation of the shaft 13. It will be readily understood that as the pinion 13 rotates the gear 14313116 stud shaft 18' actuates the connecting rod- 19, thereby reciprocating the rocker arm, once for each revolution of the gear 1-1. By the engagement of the pawl27 with one of the sixteeth of the "ratchet wheel 26, the shaft 22 is rotated onesixth of a revolution while the shaft 16 rotates a half revolution, and that the said shaft 22 restsduring the other half of each revolution of the shaft 16, while the rocker arm 21 returns the pawl 27 for reengagement.

The sprockets 28 drive an endless chain 1 of link and pin construction hereinafter deon which is a stud shaft 34, to which is pivoted one end of a connecting rod 36, the opposite end of which is slidably connected to one end of a rocker arm 37, secured at its center on a shaft 38, rotatable in bearings 39, bolted to the lower surfaces of the channels 3.

On the shaft 38 near its middle, is keyed one end of a lever arm 41, the opposite end of which is bifurcated to admit one end of a link 42 pivoted thereto. The opposite end of said link 42 is pivotally connected, as shown at 43, to a downwardly projecting tongue 44 of a slide piece 46, slidable on the nether surface of the yoke 6. Through a slot 45 in the upper wall of said yoke 6, extend bolts 47 which connect slide piece 46 with a pusher plate 48, having a downwardly extending tongue slidable in the slot 45.

The aforementioned slidable connection betwen the connecting rod 36 and one end of rocker arm 37 is made as follows: The connecting rod 36 extends through a hole in a wrist pin 49 pivoted to one end of rocker arm 37. On said extension of the connecting rod 36, is a coiled tension spring 51, one end of which bears against the wrist pin 49 and the other against a washer 52, slidable on said extension and held in position thereon by lock nuts 53. The purpose of this construction is to obviate any diflicultyarising from an interruption or clogging of bricks in the feeding mechanism. It will be seen that when the connecting rod 36 is reciprocated by the crank disk 33, the pusher plate 48 is alternately advanced and withdrawn on the surface of the yoke 6. Should the said pusher plate 48 encounter an obstruction in its advance the strain would be applied to the-relief spring 51, which compresses and allows the extending portion of the connecting rod to slide in the hole in the wrist pin 49.

Bolted to the upper surface of the yoke 6 are vertical guide plates 54, of substantially channel iron construction, having inwardly extending vertical members 56, adapted to keep a number of bricks in vertical alinement for feeding into the chain conveyer. The said vertical walls 56 are cutaway at their lower ends, as shown at 57, at a height sufficient to allow the free passage of a bottom brick of a series of bricks piled thereon.

It will be seen that every revolution of the shaft 16 causes one brick to enter the conveyer and obviously it is necessary to remove one from said conveyer at the same time.

In order to accomplish this the lower end of rocker arm 37 is provided with a wristpin 58 pivoted thereon. To the said wrist pin is secured one end of a connection rod 59, on the other end of which is a wrist pin 60, pivoted on one end of a lever arm 61, the other end of which is keyed to a shaft 62, rotatable in bearings 63, bolted to the lower edges of channels 3. Rocker arms 64 are keyed at one end to shaft 62, the other ends of said arms being provided with slots 66, in which are bolted thin strips of steel hav ing rounded ends, as shown at 67. As the shaft 62 is rotated, the rocker arms 64 bring the steel strips 67 into contact with one surface of a brick, and slide said brick out of the chain conveyer onto the upper edges of parallel bars 68 bolted to the yoke 7.

On the outer surfaces of the channels 3 are bolted bearings 69, in which rotates a shaft 71, to which are keyed grooved pulleys 7:3 around which pass

continuous cables

73 and 74. The purpose of the pulleys and cables is to provide a means of transporting the veneered bricks as they leave the chain conveyer to a remote place for drying or storage.

Each unit of the chain conveyer consists of two parallel links 76 (F 9), having holes in either end to receive pins 77. Within each of said units and extending vertically between the links 76 is a carriage casting 78. Each carriage casting has a vertical member 79, extending below the level of the links 76, two horizontal bracket members 81, having their outer faces grooved as indicated at 82, for engagement with the links 76, a shelf member 83, integral. with said brackets and having mortises 84, a vertical wall member 86 having oblique slots 87 therein, and a horizontal top member 88, on a plane parallel to that of the shelf 83. The vertical member 7 9 is of L-shaped construction and with the brackets 81, forms a bearing for a slide bar 89, slidable vertically in said bearing when actuated by a roller 91 mounted on a stud shaft 92, secured to said slide bar 89. The said slide bar 89 is held in place by a face plate 93 secured by bolts 94 to the edge of the vertical member 79.

The purpose of this construction of the carriage castings is to provide a. means of grasping, conveying, and delivering the bricks throughout the various portions of the machine. The units are arranged in pairs asshown in Fig. 9, the bricks being carried between the opposed faces of the vertical walls 86 and resting upon the shelf members 83.

In order to compensate for any inequality of the thickness of the bricks it is necessary that one member of the carriage be flexible. This is accomplished in the following manner :One member of each pair of carriage units (see Fig. 9), is fixedly secured to the links 76 by a bolt as shown at 96 while the other member of each pair is slidable between the contiguous links 7 6, and pressed against the opposed fixed member by a coiled spring 97, bearing at one end against the bottom of a hole in a boss 98, integral with the face plate 9 3, and bearing at the opposite end in a boss 99 integral witha sleeve 101 surrounding the contiguous pin 77. Mounted on the shaft 31 is ayoke 102,-

and similarly mounted on shaft 22, is a yoke 103. The

yokes

102 and 103 are connected by

longitudinal bars

104 and 105 which prevent said yokes from being rotated by the sion While they traverse that portion of the cam groove that is coaxial with the shaft 22, and return said rollers 91 to their normal position as they leave the cam groove 100.

Keyed to the shaft 16 (see Fig. 2) is a cam disk 107, having a cam groove 108 in its face to engage a roller 109, revoluble on a stud shaft 111, secured to one end of a rocker arm 112, the other end of which is secured to a shaft 113. The cam groove 108 has two segments that are coaxial with the shaft 16, allowing the rocker arm 112 to rest while the roller 109 traverses said segments and reciprocate the shaft 113 while traversing the remaining portions of said cam groove. Two rocker arms 114 are secured at one end to the shaft 113 the other ends of said arms being pivoted to the ends of connectingrods 116, pivotally connected to a sliding yoke 117, slidable in a yoke 118 bolted to the channel irons 2. Suitably secured tothe inner walls of the yoke 117 is a U-shaped knife 121. Said knife 121 has two functions, 2'. c. it is adapted to enter and close a rectangular opening 122 in the base of a reservoir 123, containing plastic material for the veneer to be applied to bricks, and is intended to be withdrawn from said opening when a brick has been placed therein by the chain conveyer, allowing the plastic material to gravitate over the edges of said brick and then enter and close said reservoir as the brick is removed from the opening 122. Itwill be seen that the cam disk 107, times these opera tions to the intermittent movement or steps of the chain conveyer.

The reservoir 123 is bolted to channel irons 2 and is wedge shaped at its base forming a hopper for delivering into opening 122, and is cylindrical in form above to permit the rotation agitators 124, of propeller construction secured to a vertical shaft 126, rotating in vertical bearings 127, of a casting 128, bolted to the flange 129 of said reservoir. The agitators are driven by a bevel.

gear 131 keyed to shaft 126. The gear 131 meshes with a like bevel gear 132, keyed to a shaft 133, rotating in a horizontal bearing 134, in the casting 12S. Keyed to shaft 133,

is a sprocket wheel 136, driven by an endless In operation, the machine is started by applying power to pulley 11, which through gear 33 the connecting rod 36 and slide 46, causes the lower brick of a pile in the feed guide 56', tobe drawn into the chain conveyer. The chain is advanced step by step, until the brick arrives at the openings 122, in reservoir 123, where it remains during the period between the steps of movement of the chain. While the chain is stopped the U-shaped knife 117 is withdrawn, the brick coated, and the knife 117 then returned to close the hopper of the reservoir, whereupon the chain undergoes the next step of its movement. As the coated brick nears the delivery end ofthe machine, the roller 91 is depressed by cam groove 100 drawing the slide bar 89 downward. The slide bar 89 is pivotally connected with the inner ends of links 141, the outer ends of which are pivoted to bolts 142, extending through holes 143 in edger plates 144. The edger plates are provided with oblique guides 146, slidable in oblique slots 147, in the vertical wall 79 of casting 7 8; As the roller 91 depresses the slide bar 89, the edger plates are drawn obliquely downward by wiping the edges of the veneered brick at the corners, leaving square edges on the ends and corners of same as it is delivered on the cables 73.

During the process so far described, the brick has occupied the position in the carriage shown in Fig. 13, in dotted lines. It will be seen that the downward oblique movement of edger plates 144 has edged the ends and a portion of the top of the brick. In order to edge that remaining portion of the top between the

points

148 and 149, I have provided a means of raising the brick in the carriage to produce a vertical wiping stroke. Suitably secured to the inner sides of the channels 2, as shown at 151 are guide strips, intended to raise the coated bricks as they encounter and are pushed over inclined portions 152 of said guides, changing the position of the brick in relation to the carriage, which wipes the remaining portions of the top after the edger plates have finished the sides and corners.

It will be seen that it is necessary to provide a means of closing the reservoir 123 while the machine is runnlng and any cessation or interruption in the feed occurs. In order'to do this, I have made a U-shaped knife 153 which telescopes over the U-shaped knife 117. The knife 153 is connected to a sliding yoke154, slidable in a yoke 156, bolted to the channels 2. To a stud shaft 157, in said yoke 156, is pivoted one end of a link 158, the opposite end of which is pivoted to a rocker arm 159, secured to a shaft 161. The shaft 161 is rotated by a lever 162 keyed thereto. The said lever 162 is provided with a latch 163 for eng ging notches in a segment rack 164 bolted at its ends to a channel 2 and the reservoir 123.

It is sometimes desirable to veneer one side or end, or one side and one end only, of a brick. In order to do this, I have provided lining plates 166 securable within the sides of the opening 122, (see Fig. 7), by screws 167. It will be seen that the said lining plates 166 occupy the space of the veneer to be left off and do not in any way interfere with the action of the telescoping U-knives 117 and 153.

H'aving thus explained the nature of the invention, anddescribed an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all off the forms of its use, the following is claimed 1.
