SPECIFICATION forming part of Letters Patent No. 577,870, dated March 2, 1897.

Application tiled April 1 3, l 8 9 6.

T0 all, whom it may concern: l

Beit known that we,.JOHN O. LUDLAM and JOHN L. MCKITTRICK, citizens of the United States, and residents of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Brick or Tile Cutting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

' The invention relates to a brick and tile cutting machine.

The object is to provide a machine that is timed or controlled by the movement of the clay; that will automatically cut the column of clay into predetermined lengths when it reaches the proper position on the table; furthermore, to improve and simplify the construction of the carrying-off table, and finally to provide a machine of this character which will be simple of construction, durable in use, and comparativelyinexpensive of production.'

Vith these objects in View the invention consists of certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a side elevation of the complete machine, the normal position of the carrying-off table being shown in full lines and the tilted position being indicated in dotted lines. Fig. 2 is a plan View wherein the cutting-frame is removed to show the transversely-laid tracks, the end pieces of the cutting-frame, and the forked pull-rod. Fig. 3 is a plan view of the machine on a larger scale than that of Fig. 2, the upper portion of the longitudinally-reciprocatin g carriage and the cutting-carriage and wire frame being removed. Fig. 4 is an end view of the machine, looking from the left of Fig. l. Fig. 5 is a longitudinal central section through the loose pinion and the pawlactuating wheel and through the fulcrnmpoint of the h-ub of the pawl. Fig. 6 is a sectional view on linen: so, Fig. 5, looking in the direction of the arrow. Fig. 7 is a side view of the pinion and the pawl. Fig. 8 is a detail view showing the construction of the ways or tracks for the transversely-moving cuttingframe. Fig. 9 is a transverse section through the lower bar of the cutting-frame with one ot' the lower wire-holders arranged thereon.

Serial No. 587,252. (No model.)

Fig. lO is an enlarged detail of the clutch mechanism for actuating the longitudinally-movable carriage.

In the drawings, A designates a suitable frame or bed formed or composed of parallel side pieces 5 5' of such length as may be required to have the track-rails 6 6 laid and secured thereon for the longitudinally-reciprocating carriage to run upon. At the front end of the bed A is formed or constructed a laterally-exten ded bed A', on which the mechanism for throwing the wire frames is mounted, substantially as shown in the drawings.

In bearing-boxes 7 7 7a, formed on or secured to the bed-frame, is journaled a main shaft B, leading from any proper power connection and source (not shown) competent to actuate the associated mechanism. On the shaft B, which has a continuous rotation, is mounted and secured a bevel-pinion H, in mesh with a large bevel gear-wheel F, the hub G of which is hollow and journaled in a bearing 9 on the side sill or piece of the bed and held against endwise movement in its bearing, as shown, and formed on its inner end with clutch-teeth 10. In the bore of the hub or sleeve G is loosely disposed a rockshaft D,having its inner end portion journaled in a bearing 1l on a central plate 12 of the bed. On the end of the shaft D is a crankarm X, in the free end of which is a crankpin 13, on which is pivotally mounted the end of a pitman V. The other end of the pitman is pivotally connected to the end cross-piece 14 of the lon gitudinally-reciprocable carriage T', as shown in Fig. 3 of the drawings. On the shaft D is splined a clutch G, the other end of which is formed with clutch-teeth 10i,vv

which engage with the teeth 1'0 on the end of' the hub G'. To automatically engage and disen gage the clutch the following-described means are provided: On the central plate 12 are strongly secured two oppositely-arranged bars 15 16, parallel to each other and in alinement with the axis of the clutch, as shown. To the projecting end of the bar 15 is fixed or formed as part thereof a flange or bar 0;, inclined inwardly and downward from the outer end or point, as shown in Fig. 10 of the drawings, and the bar 16 is formed with an incline a', the incline being from the inner portion outward and downward, as shown in ICO Fig. 3 of the drawings. On the clutch G is formed or secured a radially-arranged pin 17, on which is mounted an antifriction-roller h, which is arranged and intended to ride on the respect-ive inclines Ca a' and to thus move the clutch-section G into and out of engagement with hub or clutch section G. It being premised that the carriage T' is pushed out by the column of clay as moved onto the platen of the cutting-table, as hereinafter more fully specified, it will be perceived that when the carriage T has been moved outward to its limit, as shown in Fig. 3, the rollerb on clutchsection G' will engage the incline a and force the said section G into engagement with section G', and the shaft D will lbe rotated one half-revolution by the gearing F and H and the continuously-rotating shaft B throwing the crank over and carrying the carriage back to its point of starting, and at the same time the roller on the clutch will be carried over and into contact with the incline a, down which it will ride and release the clutch, and the table will be in a position to receive the column of moving clay, which in its progress gradually advances the carriage and throws the crank over into the position seen in Fig. 3. The roller l) will engage and ride down the incline a' and lock sections G and G together in the manner above described to effect the return of the carriage.

The longitudinal reciprocable carriage T' may be of any suitable construction. Vte have illustrated it as consisting of a substantial rectangular body or frame mounted on axles 18 19, carried by suitable iianged wheels l, running on the tracks 6 6'.

To hold the carriage T' locked at the limits of its reciprocations, a yoke B' is pivotally mounted on the bed-frame and has journaled in its upper portion a roller q. The frame of the yoke stands at an upward incline from its pivot-al point, as seen in Fig. 1 of the drawings, in which position the roller q bears and runs on a rigid bar t, secured to the end of the carriage T', the bar t being formed with notches s s' into which the roller drops when the carriage has made its movement in either direction, and is there held until a laterallyprojecting rod 7, secured to the end of the yoke, is lifted to disengage the roller from either of the notches. rlhe rod 7" is lifted by an arm S on the shaft T of the measuringdrum ot' the timing or carrying table.

R designates the timing or carrying` table of the following-described construction: On the end extensions'2l 21 of the bed-frame are rigidly mounted oppositely-arranged standards 22 22', provided with suitable bearings u in their upper ends and formed with rearwardly-projecting and upward-curved arms H', in the ends of which are iitted adjustingscrews fu, whereby the position of the carrying-frame may be adjusted vertically.

E' designates the carrying-table frame, comprising two side plates of the required length and dimensions pivotally hung in the and brace the bars 37 38.

bearings u and adapted to rest with their lower edges on the adjusting-screws r, as shown in Fig. 1, and provided with longitudinal slots 23 in their end portions, in which slots are disposed sliding blocks 24, formed with screw threaded stems 25, projected through the ends of the side plates and carrying bearing-boxes 2G ou the ends of the stems. On the screw-threaded stems 25 are mounted ad j Listing-nuts 27, whereby the bearings may be extended and retracted to produce the desired tension on the carryingapron. In the bearings 26 is journaled the end drum 28 of the carrying-apron R, arranged on the drum 2S and carried around the main drum 29, as shown. In the side pieces of plate E' are journaled a number of rollers 30, arranged to carry the upper line of the apron on a horizontal plane. The drum 29 is keyed to a shaft T, journaled in bearings disposed in the frame E', as shown. The object of hinging the carrying-table in the manner described is that it may be tilted up out of the way when not in use, as shown in dotted lines, and to provide convenient access to the bearings in which the main drum rotates.

The object of the mechanism comprising the drum 29, apron R, trip S, and coperating parts is to provide means by which the flow of clay, whether in solid column or cut into the form of brick, moving together in the form of a column on or engaging the carrying-apron R and drum H to rotate the arm S to automatically trip the locking mechanism and throw the cutting devices into action.

' On the shaft B is loosely mounted a pinion K in mesh with a large gear-wheel L, fixed on a shaft C, journaled in bearings 31 31 in standards issuing from the frame A'. shaft C is a crank-arm 32, in the free end of which is secured a bar 33, horizontally arranged, and on the bar 33 is arranged a loose sleeve 34, carrying a stirrup 35 of a pull-bar 36, from the inner end of which are projected oppositely-arranged bars 37 38, having their outer ends suitably fastened to the end pieces of the transversely reciprocating cuttingframe, as seen at 39 in Fig. 2 of the drawings.

Brace-rods 40 are provided to strengthen On an extension of the frame A' is formed a standard or bracket 41, in which is iiXed a stud-bearing c, having journaled thereon a pinion M, in mesh with the larger gear-wheel L, and on the pinion M is a crank-pin d, to which is suitably pivoted one end of a bar or rod e. This rod e has its other end projecting through an ear 4l' of a rock-arm f, pivotally supported on the frame of the machine, and is secured thereto by a nut 42'. A spring x' is coiled around said rod e and is confined between the ear 41' and a iiXed collar 43 on the rod.

To the arm f is pivotally secured one end of a rod P, having its other end connected to a crank-arm 7L on a rocking rod Q, which eX- tends longitudinally through the machine in IOO On the IIO suitable bearings and projects beyond the end of the carriage, and has fixed on the end thereof a laterally-projected lever k, the end of which is in the path of the lug 46 on the rotating arm S, secured to the sha-ft of the main drum. On the shaft B is fixed a diskwheel O, on the inner face of which is suitably mounted four antifriction-rollers r, radially arranged. To the loose pinion K is eccentrically fulcruined, by a pin j, a pawl N, the hub of which is bifurcated, as at l 2, and straddles the shaft B, the recess between the arms of the hub being eccentrically curved to afford a limited play on the shaft and the arm 2 being made longer than the arm 1 to adapt it to be moved up into the path of the rollers g by the spring fn, when the arm f is pushed from engagement with the end thereof by the rod P against the action of the spring m', whereupon the arm 2 is moved up into engagement with one of the rollers, which engagement looks the loose pinion K, so as to turn with the shaft` B, and thus actuate the interm eshing gearing to draw the cuttingtable across the column of clay and sever it into the desired forms. After the column of clay has been cut and the cutting-frame returned to its normal position (during which time the wheel M has been making its revolution and holding the arm f out of the path of movement of the revolving. pawl N) the wheel M moves the arm f into the path of movement of the pawl N, which contacts with the arm f and draws the arm 2 of the hub from engagement with theroller on the disk O and thus stops the actuating mechanism of the cutting-frame.

On the longitudinally-reciprocating carriage are laid and secured transversely-arranged tracks 48 48', formed on their outer face edges with vertical flanges 49, on which the coinciding end pieces 50 of the transversely-reciprocating cutting-frame rest and slide. The cuttin g-f rame comprises end supports 5l 5l', having their bottom faces formed counterparts of the tracks on the carriage and having on their inner top edges flanges 52. To the inner faces of the tracks is secured a keeper-plate 53, having an edge iiange 53', which sets 011 the flanges 52 to hold the cutting-frame down and against vertical displacement. The keeper-plate 53 is secured to the tracks by means of fastening-bolts p, projected through the parts, as shown, and the plates are held against upward movement by means of bolts p, projected through ears f-i f on the track-bodies and vertical sleeves 55 and having its lower end turned up to take in the lower edge portion of the cross-bar, as at b', and through the middle of the curved or hooked part of the bracket is projected an adjusting and tightening screw 58. It will be readily perceived that by means of the screw 5S the brackets may be firmly held to the cross-bar in any position in which placed.

In operation the clay is delivered in desired form from the clay-mill onto the cutting-table N and passed on over, and in so doing will move the table and turn the crank X to the position shown in Fig. 3, at which instant the roller q will drop into the recess s, provided in bar t, to hold the frame T in a locked relation to frame A. At this instant the clay, either in solid column or cut in form of brick, will pass onto the apron R and move the same to rotate the drum H and arm S, trip the mechanism by which the cutting table and apparatus is set in motion, the drum H serving as a measuring device to determine the frequency of the cut by the speed with which the arm S is rotated to trip the cutting mechanism, which movement is solely dependent on the engagement of the clay with the receiving-apron R and roller H. The usual bearing-off apron or table, having a slightly-increased speed, is used in connection with apron R to separate and bear off the brick,'so, as before stated, the clay engages the apron and the drum H will move the arm S or the lug 46 thereon to lift arm k,

which in turn will rock the shaft Q, which will, by its connection with arm f, force the arm back against the spring to release the pawl N to allow the spring y to throw the prong 2 out into the track of the roller g, thereby locking pinion K to the disk-wheel O and shaft B, by which the wheel L and crank Y will be rotated to move the cuttingtable U across or transversely to cut the clay thereon into brick or tile. At the instant of completion of the transverse movement of the cutting-table the roller b will have passed on plane a to carry clutch G into engagement with clutch G', by which shaft D and crank X will ybe rotated a distance to carry crank X to the side opposite to that shown in Fig. 3. The rollerb having engaged plane a, the clutch Gr will be drawn drawn back or disengaged from clutch G and the crank X and frame A stopped at the place of begin-` ning, which is opposite that shown in Fig. 3.

It will be understood that the several movements must be timed to produce the described results.
