SPECIFICATION forming part of Letters Patent Nd. 752,073, dated February 416, 1904.

Application filed J' anuary 12, 1903. Serial Nm 138,671K (No model.) A

resident of Painesville, in the county of 'LakeA 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 thev art to which it` appertains to make and use the same.

My invention relates to an improvement in brick-machines, an object of the invention. being to provide an improved machine of .this character in which the plunger operates in the pug-mill or miXer and so construct the plunger and its operating mechanism as to permit the operator to readily adjust the stroke of the plunger.

A further object is to provide improved mechanism for placing in position empty molds and forcing out full molds.

A further object is Vto provide a brick-machine of improved construction and operation which will be an improvement over all machines of this character heretofore known.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of` parts, as will be more fully hereinafter de-ithe block 14 with the cross-bar 13L of the scribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in longitudinal section illustrating my improvements. Fig 2 is a front view, partly broken away; and Figs. 3, 4, 5, 6, 7, and 8 are views illustrating various details of construction.

' l represents the casing of my machine,made with an opening and recess 2 in its front wall, through which access can be had to the yoke 3 for regulating the stroke of the plunger 4, as will more fully hereinafter appear. The casing l supports a central shaft 5, on which is secured the stirrers 6 and wipers 7, and this shaft has a gear S'secured on its upper end, to which motion is transmitted by suitable gearing hereinafter described. Clay is admitted to the casingthrough an openingin the back near its top and after thorough :agitation by the stirrers' is forced forward into the plunger-chamber 9 to be forced out through adie 10 in the bottom of the casing and into molds supported on a suitable table 11.

The plunger 4 is 'carried at its ends by vertical rods 12, which latter are secured to the ends of yoke 3, above'referred to. This yoke is provided at its center with a depending slotted guide 13, movable in the recess 2 in casing' l and in position of ready access to the operator, and said yoke is also provided with a cross-bar 13a. The guide 13 is for a vertically-movable slide or box 14, to which is pivotally secured one end of a pitman i6, vthe upper end of which latter is carried by the crank-arm 17 of shaft 18. The guide 13 is made with alined grooves 19 in its opposite faces, in any of which a removable plate 20 may be inserted to limit the sliding movement ofthe box, and hence regulate the stroke of plunger 3, as is readily understood. Thus it will be seen that when plate 2() is in its highest position the plunger will move a distance equal to the entire downward stroke of the shaft and plunger. When removed entirely, the plunger will not be moved at all, as the box will slide freely in the guide, and by placing the plate 2O in any of the intermediate grooves the movement of the plunger is adjusted accordingly. The return or upward stroke of the plunger is effected by the engagement of yoke 3.

The,mold-supporting table li above referred `to is located below die 10,with just the proper `space* intervening to accommodate a brickgmold, and one side of the casing is cut away lto permit the insertion of an empty mold and allow it to be placed behindV a full mold and in position to force the latter out as it is v with crank-,arms 24, and arm 25 is connected by a rod 28 with a crank-pin 29. The upper end of rod 28 is made with, an elongated slot 28? to permit movement of the crank-pin `therein without moving the mold-pusher, and

IOO

thereby permit the latter to remain at rest a suflicient length of time to enable the operator to insert an empty mold into position. This crank-pin 29 is carried by a plate 29a, having elongated slots 29b therein through which the plate is secured by.bolts to the side of a gear-wheel 30,A and these slots enable-the plate to be positioned on the wheel to perform the best results. The rod 28 is-hinged between its ends and held against bending by a spring 31, which latter, however, permits the rod to bend if Lthe molds become stuck, and thus prevent breaking or otherwise damaging the machine. Thespring is sufliciently strong to hold the rod straight under ordinary conditions, and it only bends when the molds are so securely locked that a further force applied could but result in injury to some portion of the machine.

Motion is transmitted to the. machine by lmeans of a pulley 32, loose on a horizontal drive-shaft 33 and locked thereto by my improved clutch hereinafter described. A gear 34 is keyed to shaft 33 and meshes with a larger gear 35 on another horizontal shaft 36, which also carries

gears

37 and 38, the former meshing with gear 8 on shaft 5 for driving the stirrers and wipers, while gear 38 meshes with gear 30 on crank-shaft 18 to operate the plunger 3 and mold-press, and as

gears

37 and 8 and 38 and 30 are of the same relative sizes, the pug-mill and plunger and mold-press will operate conjointly,or, in other words, the operation of each will be exactly timed to cooperate with the others.

The clutch above referred to comprises two sleeves or

members

41 and 42, the former secured to pulley 32 and the latter keyed to slide on shaft 33. These sleeves are provided with clutch-jaws on their adjacent faces, so as to lock the pulley and shaft together when the clutch members are together. The member 41 has an annular flange 43, while member 42 has a spiral flange 43,'and a vertical lever 44 is hinged between its ends on a bracket.

45a and carries at one end a curved head or enlargement 46. A hand-rod 47 is connected with one end of lever 44 to operate the same, and it will be seen that when this rod is operated to move the lever in one direction the curved head or enlargement 46 thereon will move between the

flanges

43 and 43, and owing to the spiral shape of the latter it will be forced outward, carrying with it member 42, and thus freeing the drive-pulley. The reverse motion of lever 44 causes the head or enlargement thereof to engage a hook 45, and as the latter is pivoted and bears ter toward member 41, compelling the jaws of the members to interlock and lock the pulley to the shaft. I

The operation of my improvement is as follows: Clay is supplied to the machine through the opening in the backthereof, and` it is thor- I oughly agitated and mixed by stirre-rs 6 and moved below plunger 3 by the wipers 7. Plunger 3 is then moved downward, forcing the clay out through die 10 into the brickvmolds, and the latter are forced into and out of position by the mold-pusher hereinbefore explained.

A great many changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not confine myself to the precise construction set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, whatV I claim as new, and desire to secure by Letters Patent, is-

1. In a brick-machine, the combination with a casing having a recessed front portion, of a vertical shaft in the casing carrying stirrers and wipers, a plunger located within the front portion of the pug-mill casing and inclosed thereby, a crank-shaft at the top of the casing, a yoke carrying the .plunger and having a guide located in the recess in the casing, a box mounted to slide in the guide, a pitman connecting the box and crank-shaft, and a plate to be inserted in any of a series of grooves in the guide to limit the sliding movement of the box.

2. In a brick-machine, the combination with a pug-mill casing, of a plunger located within and inclosed by the front portion thereof to force the clay through ,the bottom of the pugmill casing and a die in said bottom, a yoke carrying the plunger and having a central slotted guide movable in a recess in the front of the casing, a box or slide movable Vertically in said guide, a crank-shaft, a pitman connecting the box and crank-shaft, a removable plate adapted to be inserted in any of av IOO series of alined grooves in the guide to limit the sliding movement of the box and thereby regulate the stroke of the plunger.

3. In a brick-machine, the combination with a pug-mill casing, a plunger therein, and a die in the bottom of said casing through which the plunger forces the clay, of a mold-table `below the die, a mold-pusher, a shaft, crankarms thereon connected with said moldpusher, Aa counterweighted arm on said shaft,
