CEMENT-TILE MACHINE.

Specification of Letters Patent} Patented May 1, 1906.

Application filed January 26,1906. Serial No. 297,956.

To all whom it may concern:

'mold and the auxiliary Be a known that I, LUKE R. PEG-K, a citizen of the United States of America, residing at Caro, in the county of Tuscola and State of vlliiclugan, have invented certain new and useful Improvements in Cement-Tile Machines, of which the following is a specification, reference being had therein to the accompany- .ing drawings.

This invention is particularly designed for the commercial manufacture of tiles from cement or like cementitious material; and it consists in a machine particularly characterizpd by embodying the use of one-piece molds, al as which- Figure 1 is afront elevation of themachine.

Fig. 2 is avertical cross-section thereof. Fig. 3 is a horizontal section on line ac at, Fig. 1; Fig. 4, an enlarged horizontal section of the outer mold, and Fig. 5 is an enlarged 'horizon-' tal section of the outer mold with the inner therein as in the operation of the machine. Fig. 6 is a detached elevation of the auxiliary outer mold.

' In the drawings, A represents two stand ards rigidly united near the base by the horizontal member B and at the top by the horizontal member 0 and forming together the supporting-frame of the machine.

Dre resents aseries of inner molds secured upon t e member B, WlllGll' forms the bench.

E is a vertically-movable support slidingly engaging in vertical guide slots in the'stan'dards A.

F represents sprocket-chains suitablyconnected to the opposite ends of the support E. G G are two sprocket-wheels mounted upon a horizontal shaft H, j ournaled near the top of the frame and around which the chains F buckles f more fully hereinafter described, and shown in the accompanying drawings, in

side the main outer mold M. made of a sheet of mold in position f upon the bench. B, and then I represents openings in the sup ort E, adapted to register with the lower mo ds D.

K is a vertically-movable support guided upon'the vertical standards A and provided upon its upper face with a hopper Z.

M is a seriesof outer moldssecured in open- I ings N of the support K and depending therefrom. These molds are of sheet metal made with overlapping endswhich near the top are fastened together by a rivet d, but otherwise are free to expand at the lower end. Y

0 represents chains secured to the support K near the outer ends and carrying weights 7:. at the free end.

P represents sprocket-wheels around which the chains 0 pass. Y

Q is'a shaft journalednear the top of'the frame and carrying the sprocket-wheels P.

Q" is a crank for turning the shaft Q, and "thereby raising or lowering the support K. is the auxiliary outer mold which fits in- This mold is liable material, preferably of roofing-paper o the necessary strength and waterproof quality to stand extended use, and its longitudinal edges-are made to overlap and are detachably fastened together by buttons '2', or other like fasteningswhich will be found most suitable. I

The machine being thus. constructed and arranged as shown and described, the operation is as follows: First, the support E, carrying the clamping-rings I, is lowered down the support K, carrying the outer molds, is likewise lowered in position after each has first received oneof the auxiliary molds R, which can be readilyintro duced from below while the'mo'lds are in the elevated position. 4 (Shown in Fig. 1.) Inlowering the outer molds it will be seen that their lower" edges will be guided into position by the lugs b of the clamping-rings, (which have been previously opened out, as shown in Fig.

5, and. aft er mgamgs are shut, thereby contracting t lower ends'of the'outer molds, whit 3h on account of having open seams (except at the top, where the rivets (i hold them together,

they are in position the clampare normally flaring outwardly toward the lower end. The molds are now in position, and cement of proper consistency for castin is thrown into the hopper and distribute into the spaces between therespective molds jtiles are suitably hardened t e auxiliary molds are their unbuttoned and removed and in a wen 415cm mans-a 15 arm the tiles.

After giving sufiicient timelforthe cement to set theclaimps are thrown open again and the outer molds are raised.) This leayesthe aux- 7 h he tiles cast within iliary outernrolds -wi g Y undisturbed in positiomupon the inner mold, and by raising now'the support E the tiles,

with the aumliary outer mold remaining 4thereon,vvillbestriip1ped of the inner mold an then removedjfor' rtherdryin- After the are used again; i v

In the operation offthe' clamps I it will not be necessary 'to" closed provided there is sufiicient friction in their plvotal connections.

3 Of course the'machine maybe constructed witha lesser orwith a greater number of molds, and the raising and lowering devices forthe movablesupports of the'clamps and outer molds will' 'be arranged to provide the Il o necessary power; and, if desired, mechanical.

power may be readily substituted for man ual power, although it does not require much :powerto operate my machine.

' mold, for which I have fonnd'asphalt ro ofinga With machines of the character described perfect tiles up to the largest 'j COIDlIlBIfOlfll sizes may be made, and the manipulation is very simple and within the capacity of ordinary unskilled labor, and it will be readilyv understood that the keynote of'my invention is based upon the use of the auxiliary outer paper having a smooth hard glossy surface cheapest and best adapted, although I do not limit the scope of my invention to such ma:

A terialalone, but claim the use of any material of similar or like character.

, Having thus fully described y imgltibn, what I claim is 1.- In a cement-tile machine the combination with one-piece inner and outer molds, of

one-piece auxiliary outer molds formed of a pliable sheet of a material such as tar or roof ing paper and provided upon 0 osite ends with fastening devices detacha y connecting the ends of the sheettogether and forming it into an open-ended mold adapted to form a lining for the outer moldin casting the tile and an independent and removable outer support for the tile after casting it.

72. In a cement-tile machine, the eombination with an inner mold, of an outer mold adaptedto diametrically expand and cone tract at least for a portion of its length, and

an auxiliary outer mold formed of a single sheet of pliable material with overlapping ends provided with fastening devices detachably securing the ends together, said auxiliary molds adapted .to form a non-adhesive lining for the outer mold in casting the tile and a removable independent outer support for the tile after the removal of the outer mold.

, 4. *In'a cement-tile machine, the combination with an inner mold mounted upon a base, a vertically-movable outer mold openended and contractible for a portion of its length, a vertically-movable clamping-ring adapted to contract. the outer mold upon its lower end and form the base thereon in cast-' ing the tile and an auxiliary outer' mold adapted to form a non-adhesive. lining for the outer mold in eastin the tile and an independent andremovab e outer support for the 3 tile after the removal of the outer mold.

.- 5. In a cement-tile machine the combina tion with aQsu pOrting-frame, of an inner mold rigidly supported. thereon, an outer mold vertically movably supported insaid frame, and adapted'to'register with the in ner mold, said mold bein contractible for a portion of its length, a c ampin' -ring vertically movably supported in sai frame and adap ed to register with the inner mold and form the base of the mold in casting the tile and-an auxiliary outer mold formed of a sheet of roofing-paper with overlapping ends detachably1 connected together and adapted 'nin'g for the outer mold in casting the tile after the withdrawal of the outer mold.

6. In-. a cement-tile machine, the combination-witha supporting-frame and an inner form the base of the mold in casting the tile, a said clamping -ring composed of pivoted halves provided with upwardly-projecting guide-lugs adapted to engage the lower end, of the outer mold and center and contract the same in the operative position of the parts.

7. In a cement-tile machine, the combination with a supporting-frame, of a series of inner molds stationarily supported in the frame, a corresponding series of outer molds, a common support for the same vertically guided in the'frame, a series of clampingrings'adapted to cooperate with the inner and outer molds 1n the manner described, a common support for said clamping-rings vertically guided in the frame, two actuatingshafts journaled in the frame, and actuating connection between said shafts and the su ports and adapted to raise and lower the same independently of each other.

8.. In a cement-tile machine, the combina+ tion with a sup orting-frame'formed with adapted to register with the inner molds,

clamping rings mounted upon the last-i named support-around the openings therein, and adapted to form clamping and centering bases for the lower ends of theouter molds,

and means for vertically raising and lowering the above-named su ports independently of each other, and auxi iary outer molds adapted to form a lining for the outer molds in casting the tiles and to support the tiles independently of the outer: molds after casting the tiles.
