BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,270, dated November 19, 1889.

Application filed July 13, 1889. Serial No. 317,428. (No model.)

To @ZZ whom, may concern:

Be it known that I, CHARLES ll. IIORTON, of Wellington, in the county of Lorain and State of Ohio, have invented certain new and usef ullm provenien ts 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 an improvement in brick-machines.

The object is to provide a machine for molding brick and it consists in a mud-press geared in such a mannerthat its wear is very slight, and leaking of mud to the outside of the machine is absolutely prevented, this press being employed in connection with mechanism for regulating the stroke of the press and also mechanism for properly tempering the material for making the bricks, filling the molds to form the bricks, and means for removing the molds at predetermined intervals.

lith this end in view myinvention further consists of certain novel features of construction an d combination of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 are right and left side elevations of the machine. F ig. 3 is an end view of the mudpress. Fig. -t is a plan view of the latter. Fig. 5 is a detached view of the cam-yoke. Fig. G is a view of the mold-press, and Figs. 7 and S are detached views of parts. Fig. 9 is a front elevation, parts being broken away.

A represents the main pugging-box. The latter is of the usual construction, and the pugging-shaft 1 is journaled vertically therein and furnished with the grinders 2 2 at short intervals throughout its length. The mudpress 3 is located at the lower end of the pugging-box an d to one side of the pugging-shaft, as shown. The blade of this press is fiat on the face 1, which presses the mud, and preferably oval or rounded on the opposite or upper face 5. The stufiing-box is made to prevent mud from working its way into the box or its bearings of the press, and it is constructed as follows: An annular chamber 6, about one and a quarter inch deep by seveneighths wide, is made around the shaft 7, and in the bottom of this chamber is placed an elastic packing, and on top of this packingis placed a metal ring 9, and against the latter is pressed the follower 10, which is held securely in place by bolts or similar means 11, passing through ears 12 l2, as shown in Fig. 2. lVhen it is necessary to crowd the follower, the main boxes are loosened slightly, (they being made in halves,) and after drawing up the follower by means of the bolts extending through the ears the main box is again tightened. The metallic ring forms a tight joint against the end of the follower, so as to elitirely exclude the mudfrom the bearing, which is importantin this style of press.

lVhen the press is down, the mud, being worked andv ground by the grinders, iills the space left. by the press going down, and as thc press comes back the mud rolls over the top of the press Ain front and in position to Depressed through the dies 13 into the molds 1-1 14 below.

In order to work different clays, and as it is impossible to temper different clays alike, it isv necessary that the mud-press 3 should be entirely under the control of the operator, so that its stroke may be regulated. The full stroke of the press is about aquarter-revolution, and t-he power is exerted from one end of the machine by means of the following mechanism: A crank 15 is fastened t-o one end of the shaft on which the mud-press is mounted, and an extensible pitman 16 connects this crank with a crank-disk 17, which is fastened to the end of a shaft on which is a pinion (not shown) driven by a bevel gearwheel 18, ailixed to the main puggin0sl1aft 1, and the latter is generally driven by horsepower attached to a lever (not shown) fastened to the socket 18, or it maybe driven by power communicated by belt or rods.

To return to 'the extensible pitman, it should be explained that it is so made in order to control the movement of the press, as different lengths of strokes are required with clay of different quality and consistency. The pitman is slotted at its lower end and arranged to allow the toothed piece 19 to slide therein the full length of the stroke, unless prevented by the dog 20, which is pivoted t0 IOO the pitman. At each revolution of the crankdisk 17 the pitman is drawn upward until its end engages the end of the toothed piece, when the latter is carried along` with it. The dog 2O naturally drops by gravity into each notch until it linally drops into the top notch. Here it is retained, and upon the downstroke the crank would carry the mud-press the full lengt-h of its stroke, thus pressing the mud to the utmost capacity; but to regulate this stroke and lessen the pressure I arrange an escape-slide 21 (somewhat longer than the stroke) on the side of the machine. This slide is slotted and held loosely on the side of the machine by headed bolts 22, so that it will work easily up and down with the movement of the lever 23, which is connectedwith it by a pin 24, the opposite end of the lever being held to the machine by a link 25. A series of notches are arranged to engage the lever and hold it in position. New it is obvious if the lever is placedin the upper notch the pin 26 in the dog, which projects toward the machine, would not pass out far enough in its upward movement to ride over the escapeslide 21. So, instead, the dog will drop into each notch until at last it will remain in the top one, and therefore carry the press the full length of its stroke upon the return movement of the pitman. If, though, the lever 23 be depressed, say, to the third notch, the pin would ride over the slide and be lifted from the notched piece, and it would not return to it until three notches had been passed. It would then engage one of the lower notches and limit the length of the stroke correspondingly.

If it is desired to stop the press, the oper ator depresses the lever to the lowest notch, drawing the escape-slide down until the pin, on the dog travels the entire length of its stroke on the escape-slide out of contact with the notched piece.

In Fig. 7 the tenoned end of the toothed piece 19 is shown, the latter being arranged with side pieces to guide it on the straps of pitman 16.

An opening 27 is formed in the side of the machine and through it the molds are slid, and the following mechanism is devised to drive the mold-press at the proper periods in order to force forward the molds and effect a quick return, so that the press may remain still after being drawn back half of the time in order to allow the man feeding the molds to the machine time to slide in the molds without endangering himself or getting his mold caught. y

is supported at its middle by a wheel or roller 31, which travels in a suitable track in moldraok 32. The rear end of this press is carried by arms 33 33, which are fastened to and swing by shaft 34, which is driven by crank 35 and that by extensible pitman-rod 36, which is con nected by cam-yoke 37, said cam being driven by disk 17. This cam-yoke is driven by two anti-friction rollers 39 and 40. One of these rollers is placed on the shaft which carries the crank-disk and the other one on the back side of this disk'the proper distance away from the other roller to produce the required amount of travel. Said roller 40 on the disk, in other words, is placed so as to push out the mold at the time the mud-press is down, and in order to make it earlier or later, according to the material to be worked, other holes may be arranged 'in the disk, so that the pin on which the roller 40 is mounted may be changed forward or backward at the will cf the operator to regulate the stroke.

The handle 41 on the left side of the machine is for the purpose of raising or lowering the mold-rack to correspond to the height of the molds, ythere being two eccentrics, (one on each side,) so that by rocking the handle the mold-rack is correspondingly raised or lowered and is fastened in position by bolt 42 in the slotted casting 43.

The doors 44 44 are hinged to the front of the machine and held down by springs 45 45 in the usual manner, so that when a stone or other hard substance gets into the molds the said doors are pushed open by it as the mold passes out.

The operation has been from time to time explained, so that it would be unnecessary to enter into a detailed description here; and in conclusion I may say that various slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the particular construction herein set forth; but,

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
