TILE-RECEIVING MACHINE.

Application filed August 18, 1926. Serial No. 130,088.'

This invention has reference to a machine for handling tiles, such as are used on floors and the like in bath rooms and other places and has for its primary object to simplify and generally improve the construction of the tile receiving machine upon whichI, on January 23, 1926, applied for U. S. patent protection, the said application bearing the Serial No. 83,278.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is more fully,

disclosed, the improvement resides in the construction, combination, and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings: I 1

Figure 8 is a fragmentary top plan view with the machine provided with. the means for bunching round or square tiles on the board or tray toward each other.

Figure 9 is a sectional View approximately on the line 9-9 of Figure 8.

Figure 10 is a perspect-ive'view of the guide plate for the carriage.

Figure 11 is a front elevation of the gauge plate.

Referring now to the drawings in detail, the numeral 1 designates a frame which is preferably constructed of angle irons. This frame is placed adjacent to a tile forming machine. The frame 1, adjacent to its top, has horizontal rails 2 that provide a track for the wheels 8 of a carriage 4. The car-- riage has its fiat top arranged in a line with the outlet for tiles that have been molded in a tile making machine or press. The tile making machine or press is disclosed by the dotted lines in Figures 1 and 2 of the drawings, and isindicated by the numeral 5. Fixed to the plunger of the machine 5 and extending outwardly therefrom in the direction but over the frame 1, there is a pair of spaced horizontally disposed rods 6. These rods G-are connected with a transverse member 7 that has fixed to and depending from its corners bars 8, the lower ends of the said barsbeing connected by a transverse member 9. Adjustably secured on each of the bars 8 by means 10, there is a socket member 11, andjournaled between the bars 8 in the saidsocket 11 there is a shaft 12. Journaled on the shaft'12, adjacent to each socket or hearing member 11, and held from longitudinal movement on. the said shaft 12, there are links 13. The shaft 12, at points equidistant from the centerthcreof, is formed with enlargements 14 that receive therebetween and hold from lateral movement with respect to the shaft,'a plate 15 whose lower end is secured to the connecting element 9 for the rods. The plate 15 has secured thereon a linger 16 that is di-- 7 to alcver'19, and the lower end of each lever 19 is fixedly secured upon a shaft 20 arranged transversely with respect to the frame 1 and journaled in suitable hearings .on the said frame. The upper end of each lever 19 is slotted, as at 21,. and ,passing through these slots there are pins 22 that are received in depending brackets 23 on the i p carriage 4.

As far as the description has progressed it will be noted that the movement of the plunger of themachine 5 will impart a like n'iovement to the movable frame so that the latter will turn the bell crank levers to swing the levers 19 to move the carriage 4 either toward or away, from the machine 5. Thus it will be noted thatthe reciprocation of the plunger will cause the carriage to alternately move into tile receivingposition and away from the machinejor press.

The improvement contemplates the employment of an elevator, tlie'same including one of its faces, and in this'notch there is removably secureda 1-ack 'bar27.- Connected to a bracket on the standard there s one end of a flexible element 28, the same 'being trained over a sheave wheel 29 whose shaft is suitably journaled on the frame, and

the end of the upper lead of the flexible ele-.

meat 28 is secured to a weight 30. The weight '30 is of cylindrical formation and is receivediin. a tubular member 352. Passing through the weight 30 there is a pipe or tube v 33 on whose upper end there is fixed a cock fixed on its lower end a footpiece 35. v i .Designed to rest on the, t0p26 or'the 34:. The weight and the tube provide the elevator with a butter oi'the dash-pot type,

but the weight is also designed to move the elevator to raised position. To insure a constant or steadyfmovement of the elevator the cock is regulated to permit air flowing from the cylindrical 'n'iember or pot 32 through the weight 3 l. The standard 24 has laterally extending elevatorl the re is a tile receiving board or tray .36. This tray has its s des and its end directed toward or .,:1way from the frame 1 provided with depending cleatsi-li, and these cleats and the side plates contacting the sides of the head 26 hold the tray properly positioned on the elevator. The carriage 4 has on its flat upper face longitudinally extending ribs 38 and these ribs are designed to pass through transverse notches 39 on the under face of a guide plate 40 whose ends are fixed on the frame dircct ly above the carriage. i

.Verticallyarranged and mounted for slid-v able movement onfone end of the frame 1 there is what I' will term a' feed bar 4-1. On the face of the feed bar, adjacent tothe machine 5 there is fixed a substantially L- shapcd braeket, 42. The outwardly extending arms of the bracket 42 are threaded and screwed therethrough thereare bolt members 43and 44 respectively. Lock nuts 45 and 46 engage the bolts and hold the same adjusted on the bracket. Thefinger 16 on the slidable frame is arranged between the bolts 43 and 44, so that considerable lost mn tion will'be provided inthe vertical movement of the said slidable frame in both directions before the :bolts are contacted by the frame in the raising or loweringof the feed bar. a

The bracket 42 may have anglesides between which there is fixed the socketor housing 47 for, a spring influenced dog 48. the latter engaging with one of the teeth of the rack bar 27. The lower bearing through which thefeed bar 41 passes ispreferably chine will be elevated which will cause the slidahle frame to be moved upwardly so that the bell crank leversl'i and the levers 19 will be swun to move the carria e 4 in a )0- sition to receive the said tiles from the machine. The tiles are directed through the machine 1nto the ways between the ribs 38 on the carriage 4;, As additional material is fed into the machine and the plunger descends the slidable frame 8 will be moved downwardly and the carriage will be moved to theposition' illustrated in F igure 2 of the drawings The tiles will contact with what I have termed the guide bar 40 which will move the same from oil' of the carriage onto the tray 37. 'lhe downward movement of the plunger of the machine will cause the finger 16 to contact with the lower adjustable stop bolt, thus moving the feed bar downwardly and causing the operating dog 48 to likewise move the elevator down wardly a distance equal to the distance between two of the teeth on the rack bar and this distance also equals the thickness of the tiles which havc'been deposited on the trayllti. The holding dog prevents the u iwardmovm ment of the elevator, but the actuating dog 48 is free to move with the feed bar when the latter has its adjustable stop bolt 43 contacted by the'finger 16 on the movable frame when the plunger-of the machine 5 is raised'as will, it is thoughtyhe perfectly apparent,

On eerta'inofthe aligning transverse brace members for the frame l'there are fixed spaced longitudinally extending angle irons 51. Journal'ed in suitable bearings centrally of the angle irons 51 there are sprocket wheels around whichthere is trained an endless sprocket chain 52. This chain has outstanding lugs or fingers 53. The shaft of one of the sprocket wheels 52 has fixed thereon a pulley 54, and this pulley has arranged therearound a belt connected to a suitable source ofpower so that the chain is constantly revolved in one direction. Thus the upper lead of the chain is caused to move on the frame in a direction away from the machine 5. When series of tiles of a desired number have been stacked on the tray in a manner as above described, the elevator will be lowered so that one of the fingers 53 of the endless chain will contact with the outer cleat 37 of the said tray, thus moving the tray and the stacked tiles off of the elell l llfi

vator and outwardly on the frame to a position to be removed from the frame. Thereafter another tray 36 is arranged on the head 26 of the elevator and the latter is raised to its uppermost position. In instances where a sutiicient number of tiles has not been cast in the machine 5 to lower the elevator a suiiicient distance to cause the tray to be engaged by the belt of-the endless chain as above described, the operator will press his foot on the foot piece of the said elevator and thereby manually lower the same to a position whereby the tray will be removed from, the top of the elevator and moved over the guide wheels, 51

by the endless chain. I

Because of the engagement of the dogs with the teeth of the rack bar 27 the weight 37 cannot influence the elevator to its upper position. Therefore I provide a dog release. The dog release includes a fiat plate or bar 54 that hasrits upper end provided with an elongated slot to receive therethrough a pin 55 secured to a bracket 56 that depends from the frame. The bar is influenced in an upward direction through the medium of a spring 57. The bar passes through openings in the sockets or housings 47 or 49 for the dogs 18 and 50 and also through openings in the said dogs. The bar 5-l is provided with angle notches 58 that receive therein and limit the outward movement of the spring influenced dogs. To the lower end of the bar 5st there is secured a rod or like element 59 which is loosely connected to a pivotally supported foot pedal 60. Obviously weight upon the foot pedal 60 will cause a downward movement of the bar 54 and the angle walls provided by the notches will be brought against the dogs to move'the same out of rack bar engagement and into their housings. The weight 30 Wlll then act to elevate .the eleva-- tor.

When round or square tiles are received on the carriage they are spaced away from each other the same distance as the ribs and hexagonal tiles and in this instance it is not necessary to provide the carriage with the ribs 38, but obviously it is desirable that the tiles be bunched so that the superimposed series will properly rest upon the tray 36. To accomplish this the carriage 4: ma have at one of its ends an upwardly directed spring influenced dog catch 61 and pivoted on what I have termed the guide bar or plate 40 there is a lever 62. The lever is influenced by a spring 63 to one position and the end of the lever nearest the dog 61 is widened and formed with an angle edge 64:. The second end of the lever has pivotally secured thereto, as at 65, a rocker member which I will term a pusher arm and which is indicated by the numeral 66. When the carriage moves forward the same will'ride "plate 71 thereis a helical spring 72.

beneath the widened end of the lever andthereafter will spring outwardly so as to carriage by what I have termed the guide plate or bar 40, onto the tray 36, willbe bunched together on said tray.

In order to remove all dust from the tiles received on the tray I provide an electrically driven fan (37(see Figure 1). This permits oi the series of tiles received on the said tray properly resting one on the other.

The tilesmolded in the machine 5 .may slightly vary'in thickness which will not permit oi the same being properly stacked with our tile receiving machine Therefore, 7

I provide a gauge means whereby the operator of the machine will have ample knowh edge oi the quantity of the n'mterial to be fed thereinto; This gauge provides a pair of arms 8 which project outwardly from the upper member of the slid-able or re ciprocato y frame that carries the finger 16. A cross member (39 connects the outer ends of the arms or and passing through openings in the cross member there are bolts or hire elements whose lower orouter ends are viixed on a guide plate7 1. Surrounding each bolt and contacting with the guide v One end of the guide plate is flanged upwardly and from thence extended outwardly as at 7;. Pivotally supported on the top, adjacent one end of the plate -40,there is an arm 74 that is influenced in an upward direction through the medium of a spring 75.

This arm 74: rmderlies and contacts with the part 73 ot the gauge plate 71 or if desired with a lug on the said part 73. The arm 74: also passes through a slot 76 in a gauge plate 77 -Nhen the arm is in the center of the gauge plate the tile is being manufactured the desired thickness but when the said arm swings either upwardly or downwardly beyond the center the tile is being manufactured at undesired thicknesses. By this arrangen'ient the operator of the machine 5 has visible knowledge of the precise amount of material. to be inserted in the machine for manufacturing the tiles all of the same thicknesses.

Manitestly the gauge plate 71.contacting with the tile deposited on the tray will serve to sustain the series of tiles in proper alignment, and rack bars 27 having teeth of different lengths will be employed when the machine is used in connection with tiles of diflerent thicknesses.

It will be seen from the foregoing. de-
