BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 524,438, dated August 14, 1894. Application filed February 24, 1894. Serial No. 501.406. (No model.)

To all whom it may concern:

Be itknown that 1, CHARLES H. IIoRToN, a resident of Wellington, in the county of lo rain and State of Ohio, 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 artto which it appertains to make and use the same.

My invention relates to animprovement in brick machines-the object of the invention being to so construct the press of a brick machine that leakage of the material being treated will be prevented.

Afurther object is to constructabrick machine in such manner that the clay will be pressed into molds quickly, effectually, uniformly and automatically. r

A further object is to so construct a brick machine and particularly the press thereof, that the wear 011 the parts will be reduced to a minimum.

A further object is to construct the presser apparatus of a brick machine in such manner as to avoid the use of crank mechanism for driving the presser wings.

A further object is to provide simple and eflicient means whereby to adjust the presser box relatively to the presser arm or wing to compensate for wear.

A further object is to produce a machine for the manufacture of bricks, which'shall be simple, durable in construction, comparatively cheap to manufacture and effectual in the performance of its functions.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings: Figure 1 is an elevation partly in section. Fig. 1 is an elevation partly in section taken from the opposite side from the View shown in Fig. 1. Fig. 2 is a left hand end view showing the positions of the parts at that end of the machine when the abutmentwingis open. Fig.

.3 is a sectional View showing the abutment wing open. Fig. 4 is a view illustrating the driving gear. Fig. 5 is a view of theleft hand end of the machine showing the positions of the parts at that endof the machine when the abutment wing is closed. Fig. 6 is a sectional view through the press showing the abutment wing closed. Fig. 7 is a view of a modification.

A represents the frame of the machine, comprising a disintegrator or pug mill B and a press box 0. A shaft 13., preferably angular in cross section, extends through the pug mill from end to end thereof, the journals of said shaft being mounted in suitable boxes seen red to the ends of the frame. To this shaftaserics of diagonal arms or grinders CbiS secured and adapted, when the shaft is rotated, to agitate, thoroughly mix and convey clay from the inlet 1) of themachine to the opposite end thereof, at which latter point the pug mill is made in its bottom with an opening 0 which communicates with the press box-O located immediately under the end of the pug mill. Immediately over the outlet opening 0, the wipers a on the shaft B are made with flat faces parallel with the axis of the shaft, so that when the clay reaches the outletc it will be forced downwardly by said wipers a. into the press box.

The wall at of the press box G is made seg mental in form, concentric with a shaft B which passes through the center of said press box and at its respective ends is mounted in the frame A. The segmental wall d is supported by means of lugs d projecting rearwardly thereform and resting upon similar lugs d projecting inwardly from the framework A.

Bolts or rods 61 have their heads 01 countersunk in the inner face of the wall at and at their other ends pass loosely through perforations in the framework, said bolts or rods being screwthreaded at their free ends for the reception of nuts (1 Screws d pass through threaded perforations in the framework and at their inner ends bear against the rear face of the wall d. By means of the rods or bolts d and the screws d, the wall d of the press box can be adjusted relatively to the shaft B or more properly speaking, relatively to a presser wing D, carried by said shaft, the wall d, while being thus adjusted, being guided as well as supported by the lugs cl, 61 A shaft B is mounted in the frame-work below and to one the presserwing D. In other words, the shaft side of the shaft E the distance apart of these shafts being about equal to the width of imity to the inner end of the presser box, with an armfand in line with this arm an arm f is mounted on the shaft 13 the last-mentioned arm preferably having a roller f 3 at its free end. The arm f is mounted loosely on the shaft B and adapted to be locked thereto by means of a clutch On the shaft B preferably at the outer end thereof an arm g is secured and on the shaft B in line with this arm, an arm 9, having a roller 9 is located. Also, adj ustably, secured to the shaft B is an arm or lever g which projects rearwardly therefrom and is provided with an adjustable weight g. The free end of the Weighted arm or lever g is adapted to engage and be locked bya lug or enlargement g on a spring 9 secured to the framework. An arm 9 is adjustably secured to and projects from the shaft B said arm being adapted to engage the spring g so as to release the weighted arm or lever g as will be hereinafter explained. A set screw 9 may be employed to retain the spring out of line with the weighted arm or lever, when desired.

The shaft B is provided with a gear 1 to which motion is imparted by a gear2 carried by a shaft 3, said shaft having a belt pulley 9 secured thereto, over which a belt from any convenient source of powerpasses. The shaft B is also provided with a gear 4 which meshes with and imparts motion to a gear 5 mounted loosely on the shaft B The gear 5 is provided with an annular flange 6, against which the shoes of a friction clutch 7, secured to said shaft B are adapted to impinge, said clutch being adapted to be operated by means of a suitable lever From the construction and arrangement of parts above described, it will be seen that when clay is fed to the disintegrator or pug mill and motion is imparted to the machine, the clay, after having been mixed and fed to the outlet end of said disintegrator or pug mill, will be forced through the outlet 0 by the wipers a and into the press box, through which it will pass, and will finally pass through the outlet 71 of the press box and enter the moid (not shown) which is adapted to be insorted in the space beneath said outlet.

When the presser wing is leaving the position shown in Fig. 3, the arm f will engage the arm f and thus begin to turn the shaft B and during the travel of the presser wing bring the abutment wing to the position shown in Fig. 6, in which position it will be retained by the weighted lever g and to insure the retention of the abutment wingin this position when stiff clay is being operated upon, the spring locking device for the weighted lever above described, is employed. When the wing D shall have assumed this position the presser wing D vvill .have passed the inlet of the press box and about reached the position shown in Fig. 6. During these movements of the wings D and D, the clay, carried forward by the presser wing D will be pressed in the V-shaped space between said wings and will thus be forced through the outlet opening of the press box and into the mold beneath. Now it will be noticed that the curved wing D projects partly over the outlet h of the press box and thus said wing D' not only serves as an abutment against which the clay is forced or pressed by the presser wing D, but also serves as a valve to direct the clay through the outlet of the presser box and into the mold beneath.

When the presser wing shall have moved sufiiciently far to compress the clay into the mold to the desired extent, the arm will have reached the spring 9 and compressed it so as to release the weighted arm or lever g At the instant the shaft B is thus released, the arm g carried by the shaft B will engage the roller 9 carried by the arm g, and as the shaft continues its rotation, the arm g will be caused by the arm g to move in the arc of a circle and cause the shaft B to oscillate sufficiently to move the wing D carried thereby, out of the path of the presser wing D, as shown in Fig. 3. When the shaft B is thus turned to movethe wing D out of the path of the wing D, the arms g,g will assume the positions shown in Fig. 2 and the armsf, f will bear the relation to each other shown in Fig. 3.

If desired, the abutment wing may be retained closed solely by the weighted lever, so

that in case the clay being operated upon becomes too heavy or stiff and the machine becomes clogged owing to the effort by the maa chine to force more clay into the molds than ispossible, the weight,.which is adjusted to a certain predetermined pressure, will yield and permit the abutment wing to move back, and thus allow the continued operation of the machine, without injury thereto. But it will be observed that means are provided for locking the weighted lever in position and automatically releasing it,and this locking device may be preferable under some conditions of the clay. It will also be seen that by the adj ustment of the arms g on the shaft B the time at which the weighted lever g is released relatively to the action of the other mechanism, can be readily regulated.

By the provision of the clutch f*, the mechanism can be thrown out of operative relation without stopping the machine, should anytoo IIC

thing occur suddenly whichwould warrant the suspension of the operation of the apparatus.

A platform 7' is located under the outlet of the press box, said platform projecting be yond the framework and at its free end has small rollers j mounted therein. At the bottom of the framework, a short shaft 76 is mounted and at its respective ends carries a bell-crank lever is and a crank arm k To one arm of the bell-crank-lever and to the crank arm is, the inner ends of rods k are pivotally connected, the opposite ends of said rods terminating near the back of the frame A in upturned arms to which a bar 10 is secured and in the ends of this bar rollers 70 are mounted. To the other arm of said bellcrank-lever, one end of a rod or bar Z is pivotally connected, the other end of said rod or bar being pivotally connected to the free end of a lever '02. i

The lever m is pivoted at its opposite end to theframework of the machine and is disposed parallel with. the arm gand in the path of a roller 0 carried by said arm. The endof the framework is made with an opening 'r through which a series of molds will be inserted, one in advance of another, and all in advance of the roller k From this construction and arrangement of parts it will be seen that when the clay shall have been pressed into the mold, and the pressure devices released as above described, the roller 0 carried by the arm Q will engage the lever mand raise the free end of the same, whereupon the shaft 7.: will be turned and the rollers k carried by the bar 10 thereby caused to move toward the operator, ejecting the filled mold and placing another in position under the press box.

In lieu of the devices above described for closing the abutment wing and looking it closed for a certain length of time, a cam 8 may be secured to the shaft B and adapted to operate on one of the arms secured to said shaft to close the abutment wing and lock it in position for a predetermined length of time.
