'PBRICK-MACHINE.
A Y I SPECIFICATION forming part of Letters Patent No. 297,641, dated April 29, 1884..
Application filed February 21, 1884. (No model.)
' To all whom it may concern:
Be it known that I, FRANK" W. SHELLEY, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Brick-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to that class of brickmachines in which the mud-box is so arranged that a horizontally reciprocating plunger forces the mud vertically into the molds.
"Heretoforc inthis class of devices there has been no provision made for the disposition of the surplus mud in the mud box; hence the mud becomes packed in the latter.
One of the objects of my invention is to pro vide means for relieving the mud-box of this surplus material without interfering with the operation of the machine, and to prevent stones from interfering with the movement of the reciprocating plunger.
It has also been found in practice, when fixed wipers have been used, that stones and other solid matters get between the wipers and bottom of the drum or mixing-chambers. I propose to remedy this defect by using wipers which are adapted to accommodate themselves to the varying conditions which they may meet.
Another object of my invention is tomake the knives removable and adjustable upon the shaft extending vertically through the drum.
My invention therefore consists of constructions and combinations, all as will hereinafter be described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents the lower part of a drum or mixing-chamber having my improved attachments; Fig. 2, a section through the drum and part of the mud-box; Fig. 3, a'detail showing the manner of attaching the knives to the shaft.
The drum A, having throat A, box A and shaft E, 'the reciprocating plunger B, and the mud-box 0, having mold G", are preferably the same as those shown in patent granted to Samuel Kiser and myself on the 1st of J anuary, 1884; but it is obvious that other forms may be used in carrying out my invention.
Referring to the improvement in the mudbox, in reciprocating the plunger 13 in the mud box more mud is sometimes passed through the throat A into the latter than can be forced into the molds.
To make a perfect operating machine some means must be provided for disposing of the surplus material, and I propose to accomplish the desired result by means of a movable plate,
to pass under without injury to the operating 1 parts. If desired, the surplus material may be forced back into the drum. This is accomplished by providing the end of plate 0 with a curved lip, 0 which abuts against the front wall, a, of the box A This wall a is provided with a longitudinal slot, a, which connects the mud box and drum when the plate 0 is lifted, so that the surplus material will pass back into the drum. If desired, a, lip, 0 may be added to the plate to prevent it from being lifted past the bottom of wall a.
It may be desirable to add a strip of leather or thin elastic metal, 0, to the front end of plate 0 in such manner as to cause it to abut against the front wall of the box, to prevent leakage when the rear end of the plate is raised.
The journal 0 of the plate is provided with a square extension, 0 to which is attached a lever, D, having a weight, d, adjustable'longitudinally upon the lever, to regulate the pressure at which the plate is to be tilted and set in place by screw 02.
Passing through the center of the drum is a shaft, E, for revolving the wiper E and knives E and for reciprocating the plunger, in the same manner as shown in the patent aforementioned. I
The wipers E consist of semicircular hubs e, bolted to each other upon the shaft, and provided with extensions 6, to which are pivoted the wiping-blades e by means of bolts 6 It is obvious that one of the wiping-blades IOO can be removed from its hub without interfering with the other, and that the wipers can be removed from the shaft without disturbing the other parts thereon.
The object in pivoting the wiper-blades is to permit them to ride over stones and other hard substances, which would otherwise crowd between the bottom of the drum and wiper, to the detriment of the latter.
To hold the wiping-blades to their work, I provide springs 0, attached by one end to extension 0" by screws 0", and its free end resting upon alug, c, on the outer end of the wipingblade. These springs will ordinarily hold the wiping-blades against the bottom of the drum. If, however, any inequalities should present themselves,the springs willhave sufficient elasticity to permit said blades to ride over them.
It is often desirable to remove and adjust the knives upon the shaft. Ihe knives E therefore, are provided with depressions 0 which partly embrace the shaft E and are attached together by removable bolts.
In Fig. 3 I show one means of attaching the knives to the shaft. Each knife, in addition to depression 0, is provided with an opening, 0*, and a screw-threzuled end, 0, which passes through the opening 0 in its mate, and is held in place by nuts c".
Instead of providing the knives with screwthreaded ends a", they may be provided with extensions c having openings 0, through which and openings 0 bolts 0 are passed for clamping the knives to the shaft.
\Vhat I claim as new is 1. In a brickmachine, a mud-box having a loose tilting plate forming the cover thereof, substantially as described.
2. In a brick-machine, the combination of a mud-box having a loose tilting plate forming the cover thereof, and a reciprocating plunger working horizontally in said box, substantially as described.
8. In a brick-machine, the combination of a mud-drum, a mud-box connected with said drum, and having a loose tilting plate forming the cover thereof, and a reciprocating plunger working horizontally in said box, substantially as described.
4. I11 a brick-machine, the combination of a mud-drum having an opening or slot, a, a mud-box connected with said drum, and having atilting plate provided with a curved lip, and a horizontally-reciprocating plunger in said box, substantially as described.
5. In a brick-machine, the combination of amud-drum having an opening or slot, at, a mud-box connected to said drum, and having a tilting plate provided with a curved lip and a strip, and a horizontally-reciprocating plunger, substantially as described.
6. In a brick-machine, a mud-box having a pivoted plate provided at its forward or front end with a strip of leather or equivalent substance, substantially as described.
7. In a brick-machine, a mud-box having a tilting plate provided with a curved lip, substantially as described.
8. In a brick-machine, a mud-box having a tilting plate provided with a curved lip and a longitudinal strip,substantially as described.
9. In a brick-machine, the combination of a mud-box having a loose tilting cover, and means for automatically returning said cover to its place when tilted, substantially as de scribed.
10. In a brick-machine, a wiper consisting of a hub and extensions forming the wiperblades, which are pivoted at their inner ends to the hub and adapted to ride over obstructions on any part of the bottom, substantially as described.
11. In a brick-machine, a wiper-blade pivoted to the hub, and having a spring forholding said blades against the bottom of the drum, substantially as described.
12. In a brick-machine, the combination of a shaft and knives, which are provided with a curved part, 0 screw-threaded end 0", openings c", and nuts c", for clamping the blades onto the shaft, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
FRANK \V. SHELLEY.
