CUT-OFF TABLE FOR BRICK-MACHINES.

SPECIFICATION forming part of Letters Patent No. 392,952, dated November 13, 1888.

Application filed May 24, 1888. l Serial No. 274,953. (No model.)

To all whom, it may concern.-

Beit known that I, JOHN FnReUssoN, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Cut-Off and Delivery Tables for Brick or Tile Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. ro Myinvention relates to the class of machines described in my United States Patent No. 375,319; and it may be said .to consist in the peculiar construction, combination, and arrangement of devices hereinafter' described, and pointed out in the claims.

In the drawings, which illustrate the manner of carrying out my invention, Figure 1 is a plan view of a machine embodying my improvements. Fig. 2 is a broken plan view,en o larged, of the reciprocating cutoff carriage. Fig. 3 is a side elevation. Fig. 4 is a broken sectional side elevation showing the cut-off' carriage and its connections on an enlarged scale. Fig. 5 is an end view ofdelivery end ofmachine. Fig. 6 is a detail View in perspective of a palettefeeding roller used in making up the invention. Fig. 7 is a detail view illustrating the construction of the transversely-moving cutoff frame. Fig. 8 .is a detail view illus- 3o trating the construction of mechanism for reciprocating the cutoff carriage. Fig. 9 is a perspective view of a brick turned out by the machine in the form here shown, and Fig. 10 is a detail view of mechanism used in raising 3 5 and depressing the rollers on cutoff carriage.

The main frame A consists of a pair of longitudinal bars, B B, which carry a series of rollers, c, and constitute the tileway of the machine, and a suitable number of upright 4o bars or supporting-legs, A', and crossbars H. Just beneath the tileway so formed is a pair of parallel bars, B, earring a series of rollers, b, leaving a space, `12, beneath the tileway for the reception and passage of the palettes, and 4 5 the deviceslast described constitute the paletteway. An extension, D, for the palettewayisprovided at the delivery end of the machine,and it consists of a pair of parallel bars carrying 5o rollers, one end of the bars being detachably secured to the framing of the machine and the other being supportedin any convenient way, or

as shown. The purpose of this palette-way eX- tension is to receive and support the palettes after they have received the cut brick or tile until they are removed for drying, dto.

.An inclined extension for the tileway, composed of parallel side bars carrying aseries of rollers, C, and a belt, C', which latter runs around the rollers, is attached to the delivery 6o end of said way to assist in the delivery of the tiles from said way onto the palettes.

A yielding supporting-apron, R, which is preferably of the construction described in the patent hereinbefore mentioned, except that it is covered with a belt of any desired construction, is hinged to the delivery end of the inclined extension of the tileway for supporting the tiles in their passage from said eXtension to the palettes, so that said tiles may not 7o be deformed or broken and to obviate any necessity for lifting them by hand from the tileway to the palettes.

If so desired, I may dispense with the inclined extension of the tileway in some instances and attach the apron R directly to the delivery end of said way.

The cut-off carriage J may be of any desired construction, and it is arranged to be reciprocated in a longitudinal direction upon 8o suitable ways or friction-rollers, 13, by means of connecting-rods 14,1ocated on opposite sides of the machine, and having one end connected to said carriage and the other attached to double-racks 15, which are located at the re- 8 5 ceiving end ol" the machine. These connecting-rods are made in two pieces and jointed together and provided with suitable means for lengthening and shortening them, for the purpose of adjusting the carriage-movement. 9c This joint is shown at 16.

In this machine I reciprocate the cut-ofic carriage by frictional contact of the material that issues from the pugemill or tile-machine, the series of rollers c being provided with a belt, 17, which carries said material as it so issues.

The carriage-driving mechanism is arranged as follows: Upon the projecting journals 18 of the roller, that is located just adjacent to the pug-mill, pinions 19,having a broken series of ratchet-teeth, 20, are located and arranged IOO to engage the correspondingly-inclined teeth 21 of oppositely-loeated toothed bars 122 of double racks 15, so that as said pinions are continuously revolved in the direction indicated by arrow in Fig. 8 their teeth 2O will first engage the teeth of one bar and pull the carriage in one direction, and then engage the teeth of the other bar and reverse the direction of the said carriage, and reciprocate it the proper distance to form a series of brick or tile. It will thus be observed that the necessary power for reciprocating said carriage is derived from the moving material as it issues from the pug-mill.

'Ihe cutoff carriage J is composed of lon gitudinally-parallel bars K K and suitable crossbars to form a rectangnlarframe or bedplate which rests upon suitable stationary friction-rollers, 13, mounted in suitable bearings in the main frame, and which carriage carries aserics of vertically-movable rollers, 22,which are adapted to be raised when the carriage is moved toward the material and depressed when moved away from the tile-machine, so that the carriage may easily run under the solid material and 'permit during the cutting operation (which is performed during forward movement of said carriage) the portion of material that is being cnt to rest upon nonrevoluble bars 26, the cutting operation being thereby more efficiently performed.

rlhe mechanism for raising and depressing the rollers 22, carried by the carriage, may be described as :follows: Vhen the carriage is moved forward by the issuing material, the forward ends of bars 23 come in contact with a stop or lug, 125, located on the main frame, and the carriage continues to move a short distance, and the links 24 are then brought in' position at right angles to bars 23 and in a vertical position, and their attached rollers are projected upwardly against the material which rests upon them, which position they retain until the carriage nears the limit of its return movement, when a catch, 27, carried by the carriage,co1nes in contact with a cam sur` face or incline, 28, and is raised ont of notch or depression 29,'formed in said bar, which releases said bar,and the weight of the material upon the rollers 22 (aided by gravity of the parts themselves) causes the hangers 25 to as sume an exact, orl nearly exact, vertical position andthe links 24 to assume their normal position at au incline, and said rollers will thereby be depressed. It will be observed that when said rollers are in normal position they are depressed about level with the upper edge of stationary bars 26, and that the normal position of links 24 is an inclined one,

as indicated by dotted lines in Fig. 4. I

Asuitable cut-ofi` frame, L, carrying a series of cutting-wires, M, is adapted to be reciprocated within or upon the cut-off carriage in al direction that is transverse to the material carried by said carriage, the arrangement being such that said wires will make a cut when moved in either direction, cutting both across and back to the starting-point. Said frame is mounted in suitable ways, 30, on the carriage, and is to be slid back and forth by hand or by any other suitable means desired.

For the purpose of canting the cuttingwires at their upper ends, so as to make a vdraw-cut through the material, the upper ends of said wires are mounted in a movable frame, 31, which is provided with a suitable hand-piece, 32, for moving by hand or by other suitable means. The canted position of the wires is shown in Fig. 5, in which the cutting-frame is shown in position just after having made a eut and with said frame fully drawn out toward the operator. A cross-bar or hand-hold, N, projects upwardly from the carriage, so as to be conveniently grasped by the operator while operating the cut-off frame. l

The lower ends of the cutting-wires M are secured to small sliding rods 33, which form a part of the cuttingframe and which work in grooves 34, formed in the lowerside of stationary bars 26. (See Fig. 7.) By means of suitable thumb-screws, 3G, any desired tension may be given to the cutting-wires.

For the purpose of clamping the material after it passes onto the carriage and during the cutting operation, I locate automatic compression or clamping jaws O on either side of the material, as shown. The construction and operation of these clampingjaws are as follows: They are arranged to be transversely reciprocated by means of vertical pivoted levers O and toggles I), so as to clamp the material just before the cutting operation is begun and to release the same just after such operation is finished and as the earriagebegins to move back toward the starting-point, so that the cut material may be discharged from said carriage by the backward movement thereof, as it is during operation.

For the purpose ol' straightening out the toggles I), and thereby forcing the upper ends of pivoted levers Oinwardly, I secure a hori zontal and vertically movable bar, P', to the middle of said toggle and raise and depress said bar at the proper time and by means which will be immediately described. This latter operation may be accomplished in Various ways; but I prefer that which I here show for KV:the purpose, and which is as follows:

S is a cam-plate hinged at one end to the main framing, so that its free end may rise and fall, and which is adapted to raise and lower the bar I as the carriageis reciprocated during operation. To do this, I make the arrangement such that said bar passes entirely around said cams, (there being a cam located at either end of said bar Pon oppositesides of the machine.) The ends of said bar are pro vided with friction-rollers @,so that it may more readily roll around upon said cams. For the purpose of raising the said bar I?l and starting it over the upper side of said cams as the carriage is moved outwardly any desired means may be employed; but I prefer to arrange swinging horizontal bars 40 under either IOO IIO

end of said bar P' and suspend them by means of pivoted links 41. Said swinging bars are provided with stops 42, with which said bar Pcomes in contact as it moves outwardlywith the carriage, and thereby presses the said swinging bars outwardly toward the delivery end of the machine. Said swinging bars being swung by pivoted links, it is obvious that as they are swung outwardly they must also rise, which they do, raising the bar P with them a sufficient distance to start it over the upper edge of cams S, and it (as the movement of the carriage continues outwardly) passes entirely around said bars, and said bars run off the pivoted ends of said cams and drop down to normal position, after which the carriage is ready to make a return movement. After bar P'runs off the pivoted ends of cams S it drops downwardly, and its weight, acting upon toggles I?, closes the jaws O firmly upon the material. It is obvious that I may use springs or other devices to assist in this clamping operation, if I so desire.

In Fig. 4 the cams S are shown just in position to run under the bar P', with the carriage near the limit of its outward movement. The ends of bar P are guided in a vertical plane by means of suitable guides, 44, depending from the carriage. Oppositely-located vertical rollers 50 are adjustably mounted upon the carriage at its receiving end for the purpose of properly guiding the entering material. A

tightening-roller, 5l, for belt 17 is located in the tileway. rIhe palettes F used in the inachine may be of any ordinary form used for such purpose.

One side of the machine is provided with a table or platform, I, upon which the palettesv are to be placed in feeding them to the machine. A portion of this platform is cut away to form a passage-way, I', through which the operator may insert his arm to place the palettes in position.

Suitable guiding gages or strips of any desired form for the palettes during their passage through the machine may be and are provided.

For feeding the palettes automatically after they have been placed inthe machine, I arrange a suitable automatic feed-roller, 60, near the delivery end of the machine for automatically feeding the palettes and discharging them after they have received the cut material. This roller is preferably provided with teeth or serrations upon its outer surface for engaging the under side of the palettes during their passage over it. If so desired, any number of feeding-rollers may be used in making up the machine, although I have found that one is amply sufficient for the work required. This feed-roller is provided with devices that will cause it to revolve intermittently and move the palettes outwardly at each return-stroke of the cut-off carriage, so as to receive each successive charge of the cut material. These actuating devices may be of any preferred construction, or they may be as follows: At one end of roll G0,I locate a pinion, 6l, which is adapted to be engaged by another pinion, 62,

mounted on short shaft 63, which latter has 7o suitable bearings in the main framing of the machine. Onthe opposite end of shaft 63 a ratchet-pinion, 6i, is mounted, and to which an intermittent rotary motion is given by a toothed bar, 65, mounted on the carriage. This 7 5 construction is more clearly shown in Fig. 6. The lower ends of clamping-jaws O are cut away at 70, so that they will not rest upon or come in contact with rollers 22.

With the foregoing construction the opera- 8o tion of the machine will be about as follows: The brick or tile material is forced from the dies of the png-mill onto the receiving end of the tileway and onto the tileway-belt 17, the

forward movement of said material running said belt as it passes over it. After a sufficient length of material is located on the carriage J, y the cut-off frame is moved one way or the other, (as desired) causing the wires to cut the material into as many pieces as arranged for, 9o

the ,sa-id carriage being reeiprocated,as before described, and discharging the cut material at each backward movement onto the palettes F,

and so on.

In some cases I may dispense with the feedroller 60 and automatically feed the palettes through the machine by means of springvratchets 90, attached to the carriage J, so as to engage the palettes during outward movement and urge them outwardly and slide over them 10o during backward movement, in the wellknown manner in which such devices operate; or I may make use of both ratchet-springs and feed rolls or rollers, as may be preferred.
