MATTER ASSIGNOR TO SAID JAECKEL.

TILE-MAKING MACHINE.

T0 all whom t may concern Be it known thatr we, HERMAN E. JAECKEL and GUsTAvn 0. MATTER, citizens of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Tile-Making Machines, of which the following is a specification.

' Qur invention relates to tile making machines, and more particularly to certain improvements in machinery for making tile, pipe sections, and the like, of plastic'material, whereby an improved glazed article is secured in a more practical and economical Among the salient objects of our invention are, to provide in a machine of the character referred to, a construction wherein the core remains stationary and the outer casing or form is revolved around it, while con-` crete or other plastic material is being fed and tamped into the space between said core and form, said material being so supported as to revolve with the form or outer casing around the core, thereby giving a smooth, glazed surface to the inside of the material, as it is formed into a tile or other cylindrical object; to provide in a machine of the character referred to, an improved core and form or outer casing, whereby it is possible to hold the core stationary, or to raise and lower it at will, and to revolve the form or outer casing around the core during the formation of the tile therein; to provide a suitable support for said form or casing with means for revolving same and upon which said form or casing can be detachably mounted to receive the tile and from which it can be readily removed'with the tile, when the latter is completed; to provide in a machine of the character referred to, improved means for feeding and tamping the material into the form as it is revolved aroundthe core;

and, in general, to provide an improved tilev making machine by means of which it is possible to quickly and economically'forma tile pipe, or other cylindrical object and to remove same `without injury thereto.

Other advantages andimportant features will appear from the following description, taken with the accompanyingdrawings illustrating one practical embodiment of the in-v vention, and in which drawings,

brokeny away to show the construction; Fig. 2 is a side elevation of the same; Fig. 3 is a side elevation of a tile with the core partially removed and the form or outer casing wholly removed therefrom; Fig. 4 is a top planview of the form or outer casing with-y out the head or bell portion; Fig. 5 is a ver-l tical sectional view thereof, taken on line 5 5 of Fig. 4; Fig. 6 is a top plan view of l tables having mounted upon the lower endsv of their lmain shafts, beveled gears 5 5, which beveled gears mesh with other beveled gears 6 6, mounted upon a shaft 7, supported in suitable bearings 8 8 and driven from a sprocket wheel 9 over whichV runs a sprocket chain 10, driven from a small sprocket lwheel upon a driving shaft l1. Two clutch members 12 13 are'mount# ed upon the shaft 7 so as to turn therewith and are adapted to be operated by means of a lever 14 whereby one or the other of said clutch members can be drawn into operating connections with the beveled gears 6 6, which turn loosely' uponthe 'shaft 7 until one of the clutches 12 or 13'is moved into connection therewith by means kof the lever 14. Through this mechanism, vone or the other of said turn-tables 3 3 is operated, said turn-tables are preferably ona floor or ground level, as indicated.

The turn tables 3 3 are each provided with a series of holding hooks 15, adapted to hook over base pieces 16 on the bottomv of the form 17, when placed'upon said turntable, said hooks and base pieces coperating to hold the forms 17 so that they' willrevolve with the turn-tables 3 3. The construction of theseforms17 is clearly -shown in Figsv3, 4, and 5. The forms arepreferably constructed in two halves so as to be removed from the formed tile inthe manner indicated in Fig. 3. The top or bell portion 18 of the form may beof cast iron, as may also be the base ring 19, while the middle portion 20 thereof, is preferably sheet metal and can be replaced when worn. The top or bell portion 18 is preferably provided with lifting pins as 21, while the base ring 19 is provided with an inner ring as 22, having a beveled edge as at 23 whereby it is supported upon the inturned beveled edge of the base ring 19. rllhe two parts of the form are clamped together by means of a clamping yoke 24, hinged upon one-half of the form and adapted to be turned over an angle clamping plate 25, upon the other half of said form, with the link portions of said yoke resting in notches 26 in said clamping plate 25. Guide clips 27-27 at the meeting edges of said form coperate in bringing and holding the two parts of the form in proper relationship. A clamping means is, of course, provided at each side of the form.

A suitable frame work preferably constructed of -beams and channel iron is erected over the turn-tables for the purpose of supporting the mechanism for lifting the cores and for holding the feeding and tamping mechanism.

The cores 28, shown in Figs. 6 and 7, are each adapted to be supported at the end of a rod 29, preferably screwed into the core, said rod carrying at its opposite end, a piston head working in a cylinder 30. lt is intended that this cylinder 30 be connected with any suitable source of air or liquid under pressure, for the purpose of raising or' lowering the piston rod 29, and the core 26 carried thereby. The core 28, like the form 17, is preferably constructed with a cast iron head 31, with strengthening ribsor webs, as indicated in dotted lines Fig. 6, and a cast iron base piece 32, provided with a central opening 33, adapted to rest upon a center pin 34 on the turn-table. rifhe middle portion of said core is preferably made of sheet metal and can be replaced when worn. rlhe head piece 81 is provided through one side of the flange thereof with an opening 81 for a purpose hereinafter more particularly referred to. Said head is also provided with a vent opening 85, for the admission of air which passes into said core and through openings 36 as the core is being raised from the formed tile, also hereinafter again referred to.

37 designates a hopper to receive the material of which the tile is to be formed, said hopper discharging into a pipe 38, pivotally supported at 39, so that it can be swung from one side of the machine to the other at will. rlhe pipe 38 is provided with a discharging joint 40, preferably having a reduced end adapted to discharge the material into the space between the form and the core, as clearly indicated in Fig. 1. The discharging section of the pipe 39 has telescopic engagement with the other sections of the pipe and carries a rod 41 working through a holding mechanism 42 and by means of which the position of said discharging pipe can be regulated. Mounted to revolve within the hopper 37 is a stirring mechanism 43 adapted to agitate the material therein and cause it to feed more readily into the pipe 38. This stirring mechanism is operated through a pair of beveled gears at 44 which are operated through a sprocket chain 45, from a sprocket wheel upon the shaft 46. Said shaft 46 is operated through a pulley at 47 by means of a belt 46 ruiming to the pulley 49, which latter pulley is driven by means of a belt 50, running upon a pulley 51, upon a driving shaft at 11, shown in Fig. 2.

Mounted to travel upon racks 52, Figs. 1 and 2, is a tamping mechanism 53, said tamping mechanism comprising a carrier frame with the gears 54 meshing with said racks, and mounted upon a short shaft which is operated by means of a sprocket chain 55, which is in turn operated from a hand whee 5,6 for the purpose of carrying the tamping mechanism from one side of the machine to the other upon said racks. Supporting rods 53', support a reciprocating holding frame 57, which moves upon said rods and is operated by means of a rod 5S driven by an eccentric 59, upon a shaft 60, which said shaft is driven through a sprocket chain 61, from a sprocket wheel 62 upon the end of the shaft 46. Tamping strips or rods preferably flat and adjustably mounted in the holding frame 57, are yieldingly held in place by means of leaf springs arranged to be pressed against said tamping strips by means of eccentric cams at 64, said cam being mounted between the plates of the frame 57 and operable by means of small hand levers 65. There are two tamping strips or rods mounted in the frame 57 so that either one or the other can be used, depending upon which turnstable is in use. it will be noticed in Fig. 1 that the tamping rod is projected through the opening 31 in the flange of the core 28, and extends down into the space bctween said core and the form or outer casing 17, there being sufficient space to permit a free reciprocating movement of said tamping strip or rod for the purpose of tamping the material into the form. il] hen the form has been filled up to the flange on the core, the tamping mechanism is shifted slightly, so that the tamping strip cr rod 63 will work within the bell of the form, and outside of the flange upon the core, thus tamping the material into the bell portion of the form.

in order to shift the tamping mechanism, it is only necessary to turn the little hand wheel 56 which operates the gears 54, which are in mesh with the rack 52, and the whole tamping mechanism, and the pipe 36, are

moved from one side of the machine to the other. The driving eccentric 59 of said tamping mechanism, slides upon the shaft 60, being attached thereto by means of a spline and feather so as to turn therewith.

A clutch member 66 upon the shaft 46, is operated by means of a handle 67 and used to throw the stirring and tamping mechanisms into and out of operation, said clutch member 66 being secured to turn with said shaft, and at the same time to slide thereupon, while the pulley 47 runs loosely upon said shaft.

In order to prevent the core from turning as the form revolves around it, we attach thereto, an arm 68 adapted to have sliding engagement with a guide rod 69, and having an anti-friction roller 70 so that the arm 68 will not interfere with the free vertical movement of the core when it is lifted out of the form 17.

The operation of the device may be briefly described as follows: Assuming the parts to be in the positions shown in Figs. l and 2, and that power is being applied to the driving shaft 11, the pulley 49 is operated through the belt 50, and the shaft 46 is operated through the belt 48; the clutch mechanism 66 has been thrown into engagement with the pulley at 47 so that the shaft 46 is revolving. The stirring mechanism in the hopper 37 is being operated through the sprocket chain 45 and the material is being fed through the pipe 38 into the space between the form or outer casing 17, and the core 28. The turn-table upon which said form is mounted is being driven through the sprocket chain 10, so that the form with the ring 22 (Fig. 5) is turning around the core 48. Through the sprocket chain 61, the shaft 60 is operated, which in turn operates the eccentric drive 59 and reciprocates the tamping head or frame 57. The tamping rod 63 is working through the opening 31 in the stationary core 2S, tamping the material into the space between the core and the outer casing, as said outer casing, together with the material, is being revolved around said core. The movement of the outer casing with its ring 22, carries the material in rubbing engagement around the core, thereby giving a smooth and glazed finish upon the inside of the tile or pipe being formed. `When the material reaches the flange upon the core, the tamping mechanism is slightly shifted so as to bring the tamping rod 63 just outside of the opening 31, thereby tamping the material into the bell portion of the form, as the form and the material revolve around the core. Vhen the form is iilled, the tamping mechanism is moved to the other side of the machine by turning the little hand wheel 56, which operates the gears atl 54, and carries the tamping mechanism upon the racks 52, to

the other turn-table'and the 'core lowered thereinto, ready to receive the material whichis tamped into the form by the'tamping rod at the other side of the tamping frame 57. Air under pressure is now ad' mitted to the cylinder 30, which operates to lift the piston therein and thereby lifts the core 28 from the form which has just been we are aware that modifications and changescan be made therein without departing from the spirit of the invention, and we do not, therefore, intend to limit ourselves to the particular showing here madefor the purpose of illustration.
