FREDERICK SOHILLINGER, OF TOLEDO, OHIO.
PRESS FOR MAKING ARTIFICIAL-STONE SLABS.
SPECIFICATION forming part of Letters Patent No. 349,861, dated September 28, 1886.
Application filed March 9, 1880.
To all whom it may concern.-
Be it known that I, FREDERICK SCHIL- LINGER, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Machines for Making Artificial-Stone Slabs, of which the following is a specification.
The object of my invention is to provide a new and improved machine for shaping and compressing artificial-stone slabs which are to be used for making pavements, walks, lining tanks, covering walls, and for other suitable p u rp oses.
The invention consists in the combination, with the press-table, of an upright frame on the same, a pressing-screw in said frame, a follower on the lower end of the screw, gearing for .moving the screw in the direction of its length, a press-plate hinged on the presstable, on which plate the slab is pressed, and of adjustable gage or holding-rods for bold ing the molds on thehinged press-plate, all as will be fully described and set forth hereinafter, and pointed out in the claims.
In the accompanying drawings, Figure l is a front View of my improved machine for making artificial stone slabs, parts being broken out and others in section. Fig. 2 is a side view of the machine.
Similar letters of reference indicate sponding parts.
The press-table A is secured on the legs A, or any other suitable support, and 011 said table a strong upright frame, B, is secured, provided near its upper end with the cross-pieces B, forming a neck through which a powerful screw-spindle, O, can pass, which also passes through a neck in the top crosspiece of the frame B. The screw-spindle 0 also passes through the nut D, located between the upper cross-piece, B, and the top cross-piece of the frame B, which nut is provided with the beve1 cog-wheel E on the shaft F, journaled in one of the uprights of the frame B, and provided with a wheel, G, for revolving it; or, in place of the said hand-wheel, it may be provided with belt-pulleys or other suitable devices for giving it rotary motion. On the lower end of the screwspindle O the follower H is mounted, which is provided with a socket for receiving the lower end of the screw-spin- Serial No. 194,594. (No model.)
dle. \Vithin a recess or opening in the follower or press-block H a nut, J, is mounted on the spindle, said nut being provided with apertures J, into which a lever can be inserted for the purpose of turning the nut. A latch or key, K, is pivoted 011 the follower, and can be swung into a vertical guide-groove, L, of one of the uprights B. The follower J is also provided with an aperture, XV, for receiving the end of the rod, by means of which the follower can be moved to and fro to remove any surplus plastic material on the mold.
The press-plate M, which has a perfect smooth upper surface, is secured to and projects from a shaft, N, mounted to turn on its longitudinal axis in lugs N on the press-table, said shaft being provided with the arm 0, on which the weight 0 is held adj ustably. The presstable is provided with lugs or supports M, on which the swinging end of the press-plate M can rest. The latch P is pivoted on the presstablc, and is acted upon by a spring, 1?, which presses the upper edge of the latch over the top edge of the swinging end of the pressplate when said plate is swung down. A rod, Q, provided with a handle, Q, is connected with the latch P, and extends under the pressplate M to the front edge of the press-table.
The racks R and R are mounted to slide below the press-table and in a longitudinal aperture in the same, respectively, and both engage with a pinion, S, mounted on the transverse shaft R having a handle, T for turning it. The ends of the racks R R are bent up, and in the upper ends of said upwardlyprojeeting parts the gage-rods V are held adjustably by the screws V.
The operation is as follows: The press-plate M is swung down upon the supports on the table A, and is locked in place by the latch P. The mold is placed upon the press-plate, and is adjusted and held in. place by the gagerods V, which can be adjusted by turning the pinion S in one direction or the other to move the said rods V toward or from each other. The plastic mass is then placed into the mold and the follower lowered by revolving the shaft F, whereby the nut D is revolved and the screw 0 is moved downward. The latch K is previously swung into the groove L to guide the follower. The follower is pressed firmly on the plastic mass in the mold, which mass is compressed. If it is desired to exert a greater pressure on the plastic mass, a lever is inserted into the apertures J of the nut J, which is turned down to rest on the bottom of the cavity or recess in the follower. When the press-block is to be removed, the direction of the rotation of the shaft Fis reversed, whereby the screw and follower are raised. The pinion S is then turned to move the gage-rods V from over the upper surface of the pressplate M, the latch P is disengaged from said presser-block by means of the handle-rod Q,
and the press-plate M and the molded slab thereon are swung up by swinging down the Weight 0 on the arm 0. The mold-slab block can then be removed very easily from the press-plate. V
I am aware that Letters Patent Nos. 78,221 and 203,811 were issued, respectively, to Me- Afee and Austin on the 26th day of May, 1868, and the lath day of May, 1878, for improvements in brick-machines, and I do not claim as my invention the construction set forth in thesaid patents. v
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A. screw-press provided with a vertical guide groove in one of theuprights, and a latch fitting in said groove, pivoted on the follower, for the purpose ofguiding the same, substantially as shown and described.
2. A press for making artificial-stone slabs, provided with a hinged press-plate on the press-table, on which plate the slabs are pressed, substantially as shown and described.
3. Apress for making artificial-stone slabs,
constructed with a press-plate hinged on the press-table and a weighted arm connected with the said hinged press-plate, substantially as shown and described.
4. A press for making artificial-stone slabs, constructed with a press-plate hinged on the press-table, and provided with a weighted arm, and-a latch for locking the swinging end of the press-plate on the table, substantially as shown and described. v
5. In a press for making artificial-stone slabs, the combination, with an upright frame, a screw, and follower, of a press-plate hinged on the press-table, a weighted arm connected with the press-plate, a latch for locking the swinging end of the press-plate on the table, and a rod connected with the latch for operating the latch, substantially as shown and described. I p
6. A press for making artificial-stone slabs, constructed of a pressplate hinged on the press-table and mechanism for moving the gage-rods toward and from each other above the press-plate, substantially as shown and described.
7. A press for making artificial-stone slabs, constructed with a press-block hinged on the press table, gage rods extending over the press-plate, racks connected with said gagerods, and a pinion engaging said racks at diametrically opposite points, substantially as shown and described.
In testimony that I claim the foregoing as I my invention I have signed my name in presence of two subscribing witnesses.
