DIE FOR BRICK-MACHINES.
SPECIFICATION forming part of Letters Patent N 0. 677,200, dated June 25, 1901.
Application filed November 20, 1900. Serial N0= 37,096- (No model.)
a horizontal section on line III III of Fig. II. Fig. IV is a perspective of a serrated-face die.
Heretofore in the formation of the rectangular strip of clay used in brick-shearing machines it has been the custom to use solid dies. These dies consisted of a solid casting, technically termed mouthpiece, and the interior opening or die portion conformed to the four sides of bricks. These castings usually weighed; from ten to fifteen pounds. The clay by its passage through the mouthpiece forms what is technically termed clay strip. This strip is the exact conformation of the four sides of-bricks; hence the necessity of having an accurate gage.
In a solid mouthpiece the defect in keeping up an accurate gage is apparent when it is taken into consideration that the clay is being fed continuously to the mouthpiece.
The friction from the clay and the gritty particles passing through wear out the die portion.
In some classes of clay it is necessary to make those portions of the mouthpiece which I are in contact with the clay of a series of removable and adjustable strips. Further, I have secured a more uniform and better graduated roughness of the inside of the monthpiece, being the first to provide such roughness by machine or hand tooling, which leaves parallel ribs or fine ridges. The advantages accomplished thereby will be more fully set forth hereinafter. V
1 represents the feed-chute; 2, the hopper; 3, the feed-knives; 4, the auger; 5, the augercylinder; 6, the auger-barrel; 7, the augerstem; 8, the liner-box; 8, the steam-inlet; 9 9, the liners; 10, the mouthpiece; 11, the clay strip; 12, the supporting-plate; 13-13, the rolls. I
The mouthpiece is constructed as follows: 14 is the back. plate of the mouthpiece, having the usual opening 15 therethrough. This back plate 14 is provided with two side lugs 16 16 and two end lugs 17 17, all of which lugs are preferably made in one and the same casting with the back plate.
18 18 are side strips, and 19 19 are end strips, which constitute the wearing portions of the die and are exposed to the direct friction of the clay. These strips are removable and adjustable, being set up to any required sized opening by means of the set-screws 20 20 in the side lugs 16 16 and the set-screws 21 21 in the end lugs 17 17.
22 is the front or retaining plate, which serves to hold the strips from being pushed out by the action of the clay. This front plate is preferably bolted to the back plate through the side and end lugs, with the bolts prolonged, so as to secure the whole monthpiece to the die-box, said bolts being shown at 23 23. 1
Clay .properly prepared is fed-through the chute 1 into hopper 2. .Revolving feed-knives 3, meshed into revolving auger 4, feed the clay forward. The interior of theauger-oylinder 5 is serrated. These serrations prevent the clay from being clogged in the auger 4. When the clay comes in contact with the liners 9 9, it is compressed by the continuous passage of clay along the auger, while the tapering of the liners toward the mouthpiece gradually forces the clay into a more compact form, so
that the main function of the mouthpiece is to act as a die as the clay is forced through it. The clay strip that emerges therefrom is a complete formation ready to be sheared crosswise into bricks. Heretofore the rolls 18 13 in the back-and-forward movement of the table in feeding the strip 11 to the shearknives would leave the clay unsupported between the travel of the rolls and the mouthpiece, and the clay strip was liable to sag down at this position and cause an unsatisfactory feed of the strip by the rolls. This objection I overcome by means of the plate 12.
It is necessary to relieve part of the friction of the rings 9 9 while the clay is being forced through them. This I accomplish by means of steam under pressure, which passes into the liner-box 8 from pipe 8. Fig. III shows spaces 24 24 between the liners, through which the steam can circulate. The liners 9 9 are ordinary castings and do not fit the box 8 snugly, nor are, they steam-tight wherethey join each other. Consequently the steam has plenty of space in which to circulate in the box and discharge against the clay.
Having described my invention, I claim- 1. A mouthpiece for a brick-machine, consisting of a back plate, two sets of removable strips constituting the entire working surface of the die, one set capable of an adjustment transversely along the length and between the working faces of the second set and a retaining-plate holding said strips from displacement. I
2. A mouthpiece for a brick-machine, constrips constituting the entire working surface of the die and set-screws in said back plate I whereby one set of said strips are adjusted, While both sets of strips are held against lateral displacement by said set-screws and a retaining pIate holding said strips against said back plate.
3. A mouthpiece for a brick-machine consisting of a back plate and strips grooved transversely to the line of feed and constituting the orifice of the die. 4
4. In a brick-machine, the combination of a box, a series of liners in said box, means whereby steam may be introduced between the liners for reducing the friction of said liners; a mouthpiece secured to said box and adjustable strips, forming the die located in said mouthpiece.
.5. In a brick-machine, a box, a series of liners in said box; means whereby steam may be introduced between the liners for reducing the friction of said liners; a mouthpiece SAML. GOURDIN GAILLARD.
