Description

@einen 'tstrs @anni @fitta JAMES HOTCHKISS AND EZRA BSS, OF SPRINGFIELD, OHIO.
Letters Patent No. 64,223, dated April 30, 1867.
IMPROVED DIE POB. BRICK TILBMAGHINES.
TO ALL WHOMIT MAY' CONCERN:
Be it known that we,VJA-MES HOTGHKISS and EZRA BUSS, of Springfield, in the county of Clark, and State of Ohio, hare-invented an Improved Die for Brick and Tile Machines; and. we dohereby declare that the following'is a full and exact description thereof, reference being liadto the accompanying drawings, making part of this specication- Figure 1 being an edge View of the improved' die made for a brick machine.
Figure 2, a front outside view thereof.
Figure 3, a central vertical section of the same.
Figure 4, an 'inside viewthereof.
Like letters `designate corresponding parts in all of the figures. y
The main feature of our invention consists in the use of friction-rollers located just outside of the mouth of the die, and projecting inward suiciently to contract the rope or ribbon of clay, and receive the full pressure thereof for the purpose of diminishing the friction in the ier and of giving a smooth and perfectsurface to the clay. In connection with the rollers, we also contract-or taper the inner surface of the die to`n the outer edge or mouth thereof, its sides projecting along the surfaces of the rollers, so as to deliver the clay to the rollers near the middle or innermost projecting surfaces thereof. Also, in connection with therollers, we employ scrapers located close to the surfaces of the said rollers, to clear them'of any clay which may adhere to them.
Let A represent the die-plate, and B the aperture of the die, being of the proper size and shape to make-v a continuous rope or ribbon of clay, to be cutjoff into bricks or tiles of any shape to which our invention may' b'e applicable. fe use, or `may use, a friction-roller for each -face of the die. /Thus, for bricks we use two rollers, C C, for the sides of the bricks, and two rollers, Ddl),V for the ends. The inner surfaces, P P, of the die contract toward the outwardledge or mouth, as shown in fig. 3, and deliver the-rope of clay to the rollers nearly but not quite to the middle or innermost surfaces thereof, substantially as shown, so that the rollers project a little further inward, and receive the full pressure of the clay. The rollers revolve freely as the clay is spun out, and change sliding to rolling friction. In order to'apply 'these rollers in the most successful and perfect manner to this purpose, certain peculiarities of construction and arrangement we find to be desirable, if not essential. I A i l l 'v Y First. A capability of'adjustment inward andloutward and si'dewise is desirable. This we conveniently effect by the employment of adjustable bearings, as G G for the journals c cV of the rollers C C, and H I-I for the journals d d of the rollers D D. The iianges gg and L 7L, respectively, of these bearings, have slots or notches, ff, through which set-screws, ZZ, pass and fasten, as in' the die-plate` A. Any equivalent means of adjustment may be adopted.
Second. The edges, s s, of the rollers are init-red or bevelled, and their adjacent mitred surfaces are brought close together, substantially as shown. This allows the different rollers to be adjusted, to aconsiderable extent, either out and in, or sidewise, without injuring the perfection of the corners of the die, so tha the corners of the bricks are sharply and accurately formed. The extent or proportion of the chamfer may be aboutAA as indicated in the drawings, or varied therefrom.
Third. The'roller's are made slightly convex or bulging in thc middle, substantially as shown, for the purpose of compensating for-the swell oi' the clay as it emerges from the die, and also, if desired.V of making the bricks slightly concave, so as to enable them to be laid more closely or with coarser mortal'. The extent of the bulge may be only very slight, or varied to suit the purpose intended.
The Scrapers I I are located outside of the'rollsrs, being secured to the die-plate oy screws,=1t n, passing through slots m m therein, or equivalent means, whereby also the positions of the Scrapers may be'adjusted. They have sharp edges which are brought close to the surfacesl of the rollers, substantially as shown, so'as to act properly to scrape o' the adhering clay. f lheir edges are also curved concavely, to correspond with the conveXly-curved surfaces of the rollers.
What we claim as our invention, and desire to secure by Letters Patent, is
The employment of friction-rollers, either adjustable or not, applied to the dies of brick and tile machines, for the purposes herein specified.
lVe also claim the contraction of the die to the mouth thereof, in combination with friction-rollers on the die, substantially as and for the purpose herein set forth.
We also claim the miti-ed or bevelled edges of the rollers, for the purposes herein specified.
We also claim the convexly-curveilor bulging form of the rollers, for the purpose herein set forth.
`We also claim Scrapers I I, in combination with the rollers, substantially as and for the purpose herein speoied-` y The above speoilcation of our improved die for brick and tile machines signed by us in presence of two subscribing Witnesses.
