To all whom it may concern:

Be it known that I, RANSOM Z. SNELL, a

citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in M achi'nesfor Making Concrete Tiling, of which the following is a specification.

This invention. relates to machines for making concrete tiling.

One'object of the invention is to provide a machine embodying such characteristics that the molds may be filled automatically and the filled mold shifted manually fromone positionin the machine to another position therein and effectually tam pod and subsequently removed from the mold manually.

Another object of the invention resides in the provision of a machine provided with a vertically movable table for the support of the mold and which is gradually lowered incident to the Weight of the material fed automatically into the mold until the table reaches a certain point in the machine, when the filled mold may be readily and quickly shifted to a stationary platform for tamping purposes, there being means provided in the machine for effecting an efficient tamping of the same or substantially the same length.

With the above and other objects in view,'

the present invention consists in the combi nation and arrangement of parts hereinafter more fullydescribed,illustrated in the accompanying drawings and particularly pointed out in the appended clauns, 1t being understood that changes may be made in the form,

proportion, size and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the draw1ngs:-Figure l isaview partly in elevation and partly in section illustrating my invention. Fig. 3 is a top plan view. view of a mold disassemhlcr'l and illustrating ati'le formed in accordance with the present i invention, and Fig. 5 is a detail view of a hood adapted for position upon the top of the mold for the purpose of holi'ling the latter in i I Rroper'ieedi-n-gof ti its assen-ibled condition.

Referiing now more particularly to thei accompanying drawings, the reference -(-. l 1ar actors 1, 2 and 3 indicate uprights journal-ed in the top'of which is a shaft 4, designed to be; continuously rotated during the operation of g the machine, through the instrnmentalily o'f:

position, the agitator fingers will be out of a belt or any other suitable means (not? Fig. 2'is a side elevation]; Fig. 4 1s a detail shown) adapted to work upon the pulley wheel '5. f 1

Slidably mounted between the uprights 1 and 2 in the guide wa s 6 is a vertically movabletable 7 which is ield normally in its upper position against the action of the cementitious material 8 in the mold 9, through the instrumentality of theteleseoping support, indicated by the'characters 10 and 11, there being a-spring in the sleeve part 10 of said support and bearing against the bottom of the table 7 and the upper end of the part 11 of said support. The table may be drawn downwardly to its lowermost position and rest upon the supports 13 on the standards 1 and 2 by the foot lever 15,whose legs 16 are pivotally mounted upon the standards 1 and 2 and whiclrhas connections 17 in the .eyes 18' on the bottom of the table 7. i (onnecting the standards 1 and 2 near their upper ends is a cross bar 19 having air upwardly directed sleeve 20, in whichdatter and througlrsaid harm is rotatably mounted a short'shaft 21, to which latter is connected in any suitable manner a'stem 22 which extends through a conical shaped hood 23 secured by means of suitable brackets 24 within the hop er '25, there being a frame 26 secured to the ower end of said stem 22 beneath said hood 23 and provided with a series of fingers 27-designed, upon rotation of the frame 26, to agitate the material 8 entering' the mold 9 between the latter and the core 28 to prevent clogging of the material and t0 insure-an even distribution or filling of the/11101419."; The mold 9 may beo'f any suitable character, but as shown in the accmnpanying drawlugs, especially in Fig. 4, it consists of two segni-cy indrical shaped members 29 and 30 i hlngedly connected at corrcs )onding longitudinal edges and adapted to have their opposite longitudinal edges coupled together by means of (:( mnections 31 and 32 or, ii preferred, solely by the ring orfunnel 33, which embraces the upper. end of the mold, as clearly 7 own in 1, and 'whoseupper edge flares *0Llt\\- i1(lly,' ZtS :slronrn, to insure the 1c cementi'tions material L05 to the m l't will be noted that the iagitato'r ii nge .7 e. endoirly'slightly within the upperpart of the mold when the latter is in its upper position upon the table 7, :so that when the mold '9, has, by its own weight incii I are dent to filling, been forced to its lowermost the mold so that the latter'may be shifted from the table 7 manually to the adjacent stationary latform-34 for tamping purposes,

the latter eing hereinafter more fully'defriction clutch mechanism 40 upon said shaft 4 adapted to clutch the sleeve 39 to the shaft 4, when desired, through the instrumentality of the handle operated lever 41 pivoted at 42 v to the standard 2 and having a link connection 43 with the clutch mechanism. Thus when the clutch mechanism 40 is thrown into operative position with the sleeve 39, the

endless conveyor 37 is caused to operateand in its operation lifts the cementitious material upwardly toward the top of the machine where it discharges the same automatically into the chute 44, which latter is secured in any suitable manner, preferably, to the standard 1 and the cross bar 19, as indicated at 45 and 46, and which delivers the material from the conveyer directly to the hopper 25 where it isforced to enter the space between .the mold 9 and the core 28, and in its assage to such space is ag tated to prevent c oggmg and insure an'evcn distribution and feeding thereof into said space throughthe. instrumentality of the agitator fingers 27 operated by the rotation of the aforesaid shaft 21, which, latterisrotated through the instrumentality of the beveled gear 47 having mesh with the beveled gear 48 carried by the aforesaid sleeve 39.

As the mold 8 is being filled, the tension of the aforesaid spring 12 beneath the table 7 is gradually overcome incident to the weight of the material in the mold upon the table/7, and by the time that the mold has been filled, the table 7 with the mold thereupon Y has reached the stops 13, which brings the table 7 into alinemcnt with the aforesaid stationary platform 34 mounted upon one of said stops 13, and another stop 49 on the standard 3. r This platform 34 is provided with an opening 50of greater cross sectional diameit being understood that the core 28 is held in the mold 9 on the stationary platform 34 by virtue of friction, and that it may bereadily withdrawn manually because of the fact that it is slightly tapered.

Slidably mounted between the standards 2 and 3 is a tampiiig device consistingof a head 51 and a cylindrical 'dopending portion 52 which is adapted to fit between the mold 9 and the core 28 and actupon the ring 53 disthe clutch. As shown in Fig. 1, the clutch posed upon the cementitious material 8 after or at the time the mold 9 is being shifted from the movable table 7 to the platform 34 to provide for an evenness of the edge of the tile formed in the mold, as will be understood.

To effect a slidable or reciprocating movement of the tamping device, there is loosely mounted ,upo the continuously operating shaft '4 a else 54, to which latter is connected a cable 55 adapted to connect with thehead 51 of the tamping device, as indicated at 56. To provide for a winding of the cable 55 upon the sleeve 54 to elevate the tamping device, there is rovided suitable clutch mechanism 57 which is thrown into and out of engagement with the sleeve 54 and shaft 4 by means of a hand 0 erated lever 58 pivoted at 59-and having a ink connection 60 with 57 is in operative position to lift the tampingdevice, and the operator may provide for {L raising and lowering of the tamping device by movement of the hand operated lever 58 upon its. pivot 59. If, however, the operator should fail to move the lever 58 prior to the time the tamping device reaches the upper limit of movement, the arm 61 on the head 51 would engage the upper curved'portion 58 of the lever 58 and automatically throw the clutch 57 out of operative relation with the shaft 4,'a11d the sleeve 54, and effect a dropping of the tamping device automat ically. I

To obviate unnecessary jar and to limit the downward movement of the tamping device, there is provided the stops 62 and 63 on the standards 2 and 3 and these stops 62 and 63 are preferably provided with rubber or other suitable cushions 64 and 65, as clearly shown in Fig. 1. Thus by properly manipulating the lever 58, the clutch 57 may be controlledso as to vary the degree of fall of the tamping device, so as to further reduce unnecessary jar-occasioned byithe tamping device engaging the stop brackets 62 and 63.

Of course, in order to insure a proper spae ing of the core and mold, there is provided in the'bottomof the space between said two elements a ring 66, and in order to hold the tamping device in elevated position during the shifting of the mold from the movable table 7- to the stationary platform 34, there is provided in one end of the head 51 of the tamping device aseries of notches 67 adapted.

to receive the inwardly directed end 68 of a lever 69 pivoted at 70 in the bracket 71-. This lever 69 may be readily and quickly thrown into and out of cotipcrativc engagement with the tamping device, as is obvious. 12 I What is claimed is 2- 1.
