SPECIFICATION forming part of Letters Patent No. 762,608, dated June 14, 1904.

Application filed July 29,1903. Serial No. 167,455. (No model.)

To all whom it. neayponcern:

Be it known that I, BYRON ERB BnoH'rnL, a subject of the King of Great Britain, residing at Waterloo, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Brick-Cutters; 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.

This invention relates to certain improvements in automatic cutting-tables or improvements of what might be termed cutters employed in connection with brick, tile, or the like machinery; and the objects and nature of my invention will be readily understood by those skilled in the art in the light of the following description of the accompanying drawings, which show a construction merely as an example from among others within the spirit and scope of my invention for purposes of explanation.

An object of the invention is to provide an improved brick or tile cutter exceedingly durable and effective in construction and which will operate easily when propelled by the bar of clay projected or expressed from the die of a continuous-bar brick or tile machine.

The invention consists in certain novel features of construction and in combinations and arrangements of parts more fully and particularly set forth and pointed out hereinafter.

Referring to the accompanying drawings, Figure 1 is a perspective view of the brickcutter. Fig. 2 is a side elevation thereof, a bar of clay being shown moving from a die onto and moving the endless table orcarrier, a brick being shown as just cut from the bar of clay by the rotating cutting-reel. Fig. 3 is a vertical cross-section taken through the cutting-reel and endless table or carrier. Fig. 4 is a sectional view taken vertically through the cutting-reel and showing the curved guide track or stop of one of the uprights and engaged by the rollers of the radially or diametrically movable arms or frames carrying the cutting wires and guide-wheels. Fig. 5 is a detail perspective view of the under sides of two adjacent sections or blocks of the endless table or carrier.

together.

In the drawings, (4 represents the parallel vertical uprights or posts at the front or receiving end of the frame of the machine.

6 represents the two parallel uprights or posts at the rear or discharge end of the frame of the machine.

The posts a 6 of each pair are rigidly secured together at their lower ends by the cross bars or pieces 0. Each cross-piece 0 between its ends is provided with an upwardly-projecting support (Z, to the top edge of which the horizontal parallel lower tracks or rails e are secured. These rails extend from one support (Z to the other support (Z, and the rails a usually overhang or project horizontally beyond the vertical end edges of the supports (Z, so as to leave spaces between the outer vertical edges of the rails e and the inner faces of the adjacent uprights or posts of the frame. The rails can be formed of metal or, if desired, can be composed of wooden bars provided with metal facings along their top sides to form the tracks on which the rollers of the endless table travel, as hereinafter described.

f represents the parallel horizontal upper rails of the machine secured to and carried by the end posts or uprights and projecting forwardly andrearwardly beyond said end posts. The roller-engaging surfaces or tracks of said upper rails f can be formed by the longitudinal angle-bars f, having the outer vertical upturned longitudinal flanges. At both ends of the machine the top rails f terminate in the approximately semicircular end pieces 9, projecting at the ends of the machine and having the curved outer edges forming continuations of the tracks of the top rails. The curved approximately semicircular track edges of the end pieces g are located in the same vertical planes as the track-surfaces on the respective sides of the machine of the upper rails f and the lower rails a. The endless traveling table or carrier moves over and is supported by these various track-surfaces, which cause the table to form the parallel horizontal upper and lower plies and the two curved end plies between the horizontal plies.

The table consists of a plurality of similar sections hinged or otherwise pivotally joined Each section consists of a flat table or carrier.

approximately oblong or rectangular block;

plate, or board 72/. These plates are hinged together at their adjoining edges by suitable hinges or pivotal connections,although, as at present advised by experiment, I prefer to couple the plates together at their ends by hinges consisting of two leaves vi, rigidly secured to the bottom faces or sides of the plates, each leaf consisting of a cross-bar and lateral arms rigid therewith and projecting therefrom, the two sets of arms of each hinge being loosely coupled together by a pivot bolt or pin 1', arranged transversely of the table and at its ends projecting beyond said lateral arms to receive the supporting-rollers 7r of the In the construction illustrated each plate or section h is provided with two supporting rollers 7r, arranged in recesses in the opposite side edges thereof and at the rear end thereof. The pivot rod or bolt 7' of each plate 71 is so arranged, preferably, that the rim or tread of the rollers is slightly in rear of or flush with the end edge of the plate. The rims or treads of the rollcrs project above and below'the flat faces of the plates 72 and said rollers travel on the upper, lower, and curved end tracks and support and carry the said plates and parts attached thereto. The hinge connections between the plates h are preferably so arranged that when the plates are traveling along the upper tracks f their end edges will practically engage, and

thus form the top ply of the table or carrier as a long fiat horizontal table onto which the bar of clay Z passes from the die m of the continuous-bar brick-machine. The continuous forward or feedmg movement of this bar of clay resting on the table causes the table to move therewith, whereby the table is actuated or driven by the movement of the bar of clay. The pivotal joints between the plates 72. are preferably located a slight distance in advance of the rear end edge of each plate that is, the axis of each hinge connection between two plates is located beneath the rear end of the forward plate and a distance in advance of the adjacent end edges of said plates. Hence the supporting-rollers 74 are removed from the planes of the meeting edges of'the plates, and when the plates at the front ends of the machine start down along the curved tracks the adjacent meeting end edges of the plates will separate a considerable distance and afford ample space for the entrance of the cutting-wires hereinafter referred to and for the outward movement of said wires without interference with the adjacent edges of the clay bar or the severed portions thereof.

Each plate 72. is provided with the cuttingreel-actuating strikers or uprights w, usually two in number, extending upwardly from the opposite side edges of the plate and about midway the length thereof. In the example illustrated each pair of uprights n. is composed of a stiff metal bar bent approximately U-shaped, with the cross or transverse portion a thereof extending transversely across and secured to the under face of the plate and with the ends a extending up at each edge of the plate and at right angles thereto. 1f desired, the central portion of the transverse part 12' of the bar can be deflected laterally, about as shown, to increase the stiffness and rigidity of the uprights n against yielding movement when operating the cutting-reel. The upper portions of the uprights n are formed with inwardly-projecting guards a to hold the bar of clay against lateral deflection or buckling, which might otherwise carry the same against the table-supporting rollers 70. The uprights a also hold the under or bottom ply of the endless table to the lower tracks by extending down beside the outer vertical edges of said tracks, while the guards 12/ extend under the bottom rails and prevent any possible excessive upward movement of the under ply-from said tracks.

The cutting-reel is mounted above the rea or discharge end of the top ply of the endless traveling table and in the upwardly-extended ends of the rear uprights b. 0 is the shaft of the reel, at its ends mounted to freely rotate in the uprights b. In the example shown this shaft carries four equally-spaced sets of radial arms p, which are provided with the brick-cutting wires (1 and the guide-wheels r. Diametrically opposite sets of arms 1 are connected together to form, in effect, diametrical or approximately diametrical frames, so that the four sets of arms p form two frames crossing each other at right angles. Each set of arms 1) is formed by a U-shaped bar, and the opposite U -shaped bars are rigidly secured together by the connectinglinks 3), usually two in number,- passing diametrically through the shaft 0, which is formed with diametrical openings or passages for that purpose and through which the links p are free to slide. sufficient length to permit the diametrical movement necessary for each diametrical frame, and the movement of each said frame is limited by the engagement of the transverse portions of the U-shaped bars with the shaft 0 of the reel.

The outer end of each arm 2 is provided with a transverse eye 7)", receiving the stud on which the guide-wheel 0' is confined to rotate, said wheels being located at the inner sides of said arms. The fastening and holding devices for the cutting-wires (1 pass through said studs on which the guide-wheels are mounted about as shown and described in United States Patent No. 719,722, issued to me February 3, 1903.

The two radially or diametrically movable frames, each carrying two cutting-wires and two pairs of guide-rollers, are movable independently of each other through the reel-shaft.

Suitable means are provided to limit or con- The links are of trol the sliding or radial movement of each cutting-wire frame of the reel with respect to the movement of each section or plate of the endless table. As at present advised I do not wish to limit myself to any specific means for this purpose in so far asother features of my invention are concerned, but as an advantageous means for this purpose show the curved cams or guides s rigidly secured to the inner faces of the extended upper ends of the rear uprights Z) and arranged to be engaged by the lateral projections 25 from the arms 7) of the cutting-wire frames of the reel. These projections t' are preferably provided with antifriction-rollers, and each arm p is provided with one projection extending horizontally and outwardly therefrom at a point'between its ends. The guides s are so arranged that as the reel revolves the projections 25 of a downwardly and rearwardly moving pair of arms 2 Will move onto the front ends of said guides s and travel along the upper surfaces thereof, thereby holding the cutting-wire frame of which said arms form a part from dropping to their limit of downward movement until the projections t pass or drop from the rear ends of said guides s, whereupon the frame isfree to slide or drop radially to its limit of downward movement.

The bar of clay rests longitudinally on the long flat surface formed by the top ply of the endless table and between the guards a of the uprights of the sections of said table. The table is constantly moved around by the advancing bar of clay, the sections'of the table moving rearwardly along the top tracks to the rear or discharge end, where each plate or section tilts downwardly from the horizontal position, with its supporting-rollers following downwardly around the curved tracks of the rear ends g, and from thence passing downwardly and forwardly to the rear ends of the lower tracks a with the plates reversed. At the front or receiving end of the machine the plates pass forwardly and upwardly from the lower horizontal tracks to the front ends g, and the rollers of the plates pass upwardly along the curved -tracks of said front ends to the front ends of'the horizontal top rails. As each plate of the table advances to the cutting-reel the uprights a of said plate engage a pair of guide rollers or wheels 0', and thereby rotate the reel carrying the cutting-wire down through the bar of clay in the vertical plane of the meeting edges between said plate and the next plate to the rear in the direction of movement of the table. The projections t of the arms carrying said wire by resting on the guides s uphold the frame carrying said wire until the said projections slip off the rear ends of the guides, which movement does not take place until the plate has assumed the tilted position on the tracks of ends g and opened the space to receive the cutting-wire between the ends of the plates where the clay bar has just been cut.

As soon as the said two plates separate at their ends, the brick having been completely severed from the bar, the reel-frame drops down, carrying the cutting-wire down into said space between the ends of the plates and out of contact with the front end of the clay bar, and thereby preventing the cutting-wires damaging the ends of the bricks. The reel is kept in rotation by the advancing uprights of the endless table, as described in my hereinbeforementioned patent.

It is evident that various changes and modifications might be resorted to in the forms, constructions, and arrangements of the parts described Without departing from the spirit and scope of my invention.
