TILE-MACHINE.

Specification of Letters Patent.

Patented May 11, 1909.

Application led September 26, 1908. Serial No. 454,873.

and adapted as to be adjustable for form-l ing tiles of different thicknesses, or to compensate for wear of the exterior contactsurfaces, and otherwise to improve the construction and arrangement of the machine to make it practically effective. This object we have accomplished by the mechanismV which is hereinafter fully described and claimed, and which is illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of our said improved tile-machine. Fig. 2 is a front elevation thereof. Fig. 3 is a central axial vertical section, enlarged, ofy the formingdevice. Fig. 4 is an enlarged upper plan view of the upper former-head. Fig' is an enlarged lower plan view of the part depicted in Fig. v4. Fig. 6 is an enlarged upper plan view of the lower former-head. Fig. 7 is an enlarged lower plan view of the part depicted .in Fig. 6. Fig. 8 is an upper plan view of the vertically-movable table for the outer mold-casing.

Similar numbers refer to similar parts throughout the several views. l

Qur machine is intended to form hollow cylindrical drain-tiles from a mixture of cement and sand, commonly denominated concrete, and this invention is an improvement upon the tile-machine for which we have a pending application for patent in the United States Patent Office, led May 11th, 1908, underSerial Number 432,034.

The essential and important feature of our improvement is in the form. and adjustable construct-ion of the former-heads used to form the interior of the tile in coperation with the outer mold-casing.` Said former-heads consist of two superposed cylindrical cores, an upper core having an integral axial sleeve adapted to be detachably secured upon a hollow cylindrical shaft 27 by means of a set-screw 67, `and a lower core 43 havingk an integral axial sleeve adapted to be detachably secured to the lower end of a solid shaft 1 by means of a set-screw 69. The two cores are relatively spaced but a narrow distance apart, while the solid shaft 1 is contained within the hollow shaft 27, the two shafts being adapted to be rotated in opposite directions by means of the mechanism to be hereinafter described. Each of said cores is provided with a plurality of forming-plates which are made adjustable in a direction leading outward from the axis of the core radially, as well as being adjustable eccentrically. The upper core 55 has but two of these forming-plates 57, located oppositely and spaced apart widely to provide a channel or chute between them for the tile-material to move therein and be permitted to pass downward between the forming-heads and the interior surface of the outer mold-casing 4l.

Each forming-plate 57 has a radial slot 5S to permit the securing therethrough of a bolt 6() adjustably, the bolt being screwed into a seat in the upper horizontal plate of the core 55 with a washer 59 seated between the head of the bolt and the top of the plate 57. Then the bolt 60 is turned to loosen its clutch upon said plate,l the latter may be moved radially outward, or may be shifted on the bolt eccentrically as desired, or adjusted in both ways. The outer portion of each plate 57 'has a depending flange which is spaced away from the outer surface of the cylindrical part of the core 55 by means of adjust-ing screws 65. The forward portion of the outer side of each of said flanges is beveled off downwardly and inwardly, which permits the moving fia-nge to grasp and compress the tile-material and form it against the interior surface of said outer moldcasing.

The lower core 43 is provided with a plurality of forming-plates 63, which however, are somewhat dissimilar from the plates 57, in this, that the depending flange of each plate is not beveled, but is increased in thickness gradually beginning with its forward end. Each flange is at its forward end bent inward toward the core 43. Each plate 63 is oriced to receive a bolt or machine-screw 62 extending through aislot 68 in the underlying core-top, the washer 73 being interposed between the bolt-head and the under face of said core-plate. The plates 63 are adjusted by turning them on said bolts, or

IOS

by moving them in or out radially when said bolts are shifted in said slots. The spacing apart of the depending fianges of the plates 63 is effected by means of the adjusting-screws 66. A sufficient number of the plates 68 is provided to have them arranged continuously about the core 43, with very little if any spacing apart of such plates. The outer curves of the plates are eccentric to the core axis, and the radial recession of the tianged forward edges permits them to grasp and compress the tilematerial and rub it smoothly against the inner wall of the outer mold-casing. The adjusting of the

plates

57 and 68 radially outward permits either of taking up any loss of the surface thereof by friction, or allows them to be adjusted to vary the thickness of the tile. The shifting of such plates eccentrically permits of an adjustment suitable within the hollow shaft independently. Said i shafts are received in bracketed bearings 7 and t attached to a backing-plate 8. This back-plate is fastened to the forward ends of

horizontal beams

32 and 33, such beams being supported by the uprights 49 and of the frame of the machine.A

the bracket-bearing 7, and is furnished at its upper end with a bevel-pinion (l. The solid shaft l extends upwardly prolonged above the pinion 6 and its upper end has a fillet which rests upon an upper bracketbearing 2 attached to the backing-plate S. A bevelpinion 3 is secured to the shaft l under the bearing 2. A horizontal shaft 5 is rotatable in bearings 9 and 1S supported by the machine-frame, and has on its forward end a bevel-gear wheel 4: in mesh with the

bevelpinions

3 and 6. An idlerpulley 14 is mounted on said shaft 5, and carries a friction-ring or seat 19 adapted to receive a friction-cone 13 when the latter is shifted in one direction. Said friction-cone and its hub is slidably but non-rotatably mounted on said shaft 5, to slide over the feather 74 on said shaft. Said hub has an annular groove to receive the forked ends ll of the upper member 2O of a bell-crank 22, which is pivoted at its angle on a stud 23 extending from a hanger l0 secured to the beam 32. The lower member of said bell-crank lever is pivotally-connected at 2l to the upper end of a connecting-rod 26, the lower end of the latter beingl pivotallY eonneeted at 29 to the short rear member litt) of a hznid-lever i253, the latter beine' niedially pivoted to the beam vl. The leze 28 is notched at a point on its lower edge to engagea pin l1*- on the plate .Q to limit its downward movement. ldlhen the lever 28 is thrown either down or up the pivotal connection 29 is moved past its deadcenter, and the friction-enne t3 is thrown into or out of contact with the friction-ring or if). The pivoted joints of the eonnected parts are so contrived as to wortY somewhat stit'lly, and thus hold any positions in which they may be placed at an); time without regard to the, influence of gravity. The power-pulley l-lthus imparts rotation to the shaft in a well-linmvn. manner, andl the bevel-gear-wheel -lthen rotates the lievelpinions 3 and (l in opposite directions. imparting the same movements to said .sha fis l and 2T and their respective care-plates if .in upward ii1o\eineiit of the lever and 43.

throws the connection 2f) the other wa)v past the dead-center, and the. friction-cone is i detached and held apart from the frictionring 19. stopping the rotations of the .shaftsI l and 27.

The outer mold-casing gl-l is supported ou the forward end of a verticallyY rm'vable table or carriage 5G, the forward end of said carriage being forn'ied in the shape of a ring with an annulus -1t2 to he the seat of the lower end of said casing. 'lhe circular opening of said ring T2 is of they same diameter as thc outer diameter of the cylindrical exterior of the former heads and their forming-plates. The carriage .iti has sleeves y and 53 whose inner hollows 'Tl and T() re- The hollow shaft 27 terminates just above spectively fit them to move freely over the, uprights i9 and o2.

25 represents a horizontal sltwve-bearingv supported by the uprights 52 and -ll. and

i in which a short sha ft 24 is rotatably mounted. large gear-wheel 'lo is mounted on said shaft: 2land meshes with a pinion li' en the power-shaft 5. cranl--pin ,l5 projects froin the forward fare of the gearwheel lf3, and on it is piv -tally mounted the upper end of connecting-rml il- 3. the lower end of the latter being` pivoted on a pintle secured between the lugs ft-T on the. earriage 5G. During one half of the rotation of the gear-wheel itl. the carriage atl is, elevated, and during the next half rotation the carriage is lowered, thus movingthe moldcasing -l-l up and down alternateljv about the forming-heads on the said shafts l and 27. is a bar whose hollow sleeves Elfi and are slidable vertically over the uprights 49 and respectively above the carriage oo, and on whose projecting;` forward end a small hopper t() is mounted. ythe inner periphery of this hopper communicates witl: and is of the saine interior diameter as the mold-casing 4l. The rear 'ardly-projeeting lOtl lifi

end of the bar 35 is vertically oriticed to permit the passage of a fixed vertical guide-bar 36, the beam or bar 35S-moving over said guide-bar, but being limited in its downward movement by a projection or engagingmeans such as a nut 37 on the lower end of said guide-bar. Then the carriage moves upward its superposed casing 41 rises till its upper edge engages the overhanging hopper At() and lifts the latter with it to the filling position indicated by the Fig. 1. Mixed materials are then deposited in the hopper flowing thence into the casing, and as the latter descends, such materials pass between the former-heads whose rotating' engaging means form a tile between themselves and said casing. When the casing has lowered a certain distance, the nut 37 engages the bar 35, and disengages the hopper from the casing, the latter moving still farhtre downward to a position where the casing and inclosed tile may be removed and an empty casing substituted.

it will be seen that the adjust-able forming-plates on the former-head cores may be adjusted without removal from the machine while at rest, and that they may be adjusted to take up wear and also to vary the thickness of the tile, and that their relative positions with regard to each other and such cores may be varied as to effect in use the amount of compression of the material desired while forming the tile. The opposite rotating of the former-heads also eifects a more complete rubbing action and resultant homogeneity in the tile.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is:

1. ln a tile machine, in combination, a mold-casing, concentric shafts oppositely rotatable in said casing, a core secured on each shaft and located one above the other, and cecentrically adjustable former-plates secured to each core, said cores and attached plates working within said casing and spaced apart therefrom.

2. in a tile machine, in combination, a mold-casing, oppositely-rotatable shafts in said casing, a core secured to each shaft, one

being located above the other, former-plates detachably secured about the outer periphery of each core, each of said plates being both radially and eccentrically adjustable from the axis of its core, said cores and attached plates working wit-hin and spaced away from said mold-casing.

3. in, a tile machine, in combination, a mold-casing, oppositely-rotatable cores in said casing located one above the other, former-plates adjustably secured to the upper core and separated from each other to leave a wide channel space therebetween,

former-plates adjustably secured about the entire outer periphery of said lower core, said cores and their attached plates being adapted to rotate within and spaced apart from the interior wall of said mold-casing.
