After'thetileihas been formed in the man- .ner well known to those familiarwith this art, the -sander or finisher is brought foriward by rolling it along thetrack ,until it stands over the ti'le, the shaperbeing then of course removed. .Thesand or cement or other. finishing material being within .the

box the handle 35 is now grasped and. the, inner or falsezbottom reciprocated 'so' as to agitate-the material, which sifts through the true bottom 32 onto the'tile;

. after which the sander is restored to its normalf position. .The knife is then brought down to cut off the surplus material. around the edges of the pallet, afterwhich the lat- .ter with the tile'thercon' is lifted out of theframe and the tile removed for 'firing in the kiln, ifv itisto be fired, orgfo'r setting .if

1 it is of cement, For lifting thepallet and tile the .treadle mechanism. above .descriibed aces is employed, and when the operator 'the consists in means for forming a hole or eye for making roofing ,tiles'as suggested above.

Inthat ease, as is'well known. to those familiarwlth the art, these-holes are necessary for theinsertion of-tli'e wires or loops by means of 'whieh the tiles are subsequently secured .to the roofing boards; and the operator. having both hands employed, it becomes desirable that'some means be present .;whereby the pin or needle which forms'the hole-may be-projected through the rib and ;a .1.'-0.ss that 1 portion of the pallet which -.for ms the same, at the right time and withz 45.

3 and9, the numeral-40 designates a pin or needle carried by the upper end of an upright. arm 41 which rises from a" bar-42 slidably .mounted in: guides 43 in the frame 4, and this bar in turn is. connected-in any suitable manner with a plunger bar-44, as by -means of a second upright arm 45.. .55

The plunger bar moves through guides 46 in the frame of the table, and connected with its front endis a plate 47 lying along the l edge of the table nearest the operator.

When now the latter leans forward sufficiently to bear-upon this plate, he moves the plunger bar 44 and the other bar 42,

and the latter by means of the arm-41' projects the-needle 40 through the rib the. underside of the tile as shown. For retracting the needle I may employ any we ferred means, but as shown in these views there is a bell-crank lever 48 pivoted at its angle at 49 to asuit-able support within the frame, its upper arm engaging a stop or pin 50 on the upper slidingbar 40-and its lower arm standing in the path of an upright pin 51 forming part of the connection 11 between the pallet-lifting pins 10 and the treadle mechanism 12. So that when the operator depresses the treadle to raise the pins and lift the pallet out of the frame, the pin ol-willtur'n' the bell crank lever and the upper arm of the latter Will strike the pin 50 and slide the bar 42 and Withdraw the needle 40 in a manner which will be clear. It; follows from this detail of construction, if adopted, that although the operator may lean against the plate 47 and project the needle at any stage in the process of forming the tile, when he comes to e ect the tile from the frame the act of lifting the pallet withdraws the needle, and

the result is that the hole formed through the .rib in the tile is not torn out as so often occurs when the operator takes out a finished tile without first withdrawing the needle. Nevertheless it might be possible to substitute other mechanism for retracting the needle, because after the latter has once been projected and the hole formed, it is not necessary that it remain 'if the consistency of'the composition is correct.

Thus is constructed a light, simple, durable, and yet efiective machine for the formation of roofing tiles by a single operator and on a small scale.' It will not be necessary for the purpose of this specification to describe the manner of or mechanism for bringing the materials to the operator or for taking away the tile when the latter is to be dried or baked, and obviously the materials, proportions, and exact details of parts are also unimportant.

What is claimed as new is:

1. In a tile forming machine, the combination with a table, a frame carried thereby and a pallet movably mounted on the frame and of a design to form a tile having ribs on its-under face; of means for lifting the pallet above the frame, means for piercing one of the ribs on the tile formed and additional means coiiperating with the pallet lifting means and the last mentioned means for disposing the latter to its inoperative position upon the disposition of the former v.to its operative position.

2. In a tile forming machine, the combination with a table, a frame carried thereby and a pallet movably mounted on said frame and of a design to form a rib on the lower face of the tile; of a foot operating means for lifting the pallet above the frame, a movable needle for. piercing the .rib on the tile formed, manually operable meansfor disposing the needle to its operative position,

and means 'coiiperating with the foot actuated means and manually operated means whereby to actuate the latter upon the actuation: of the former-to dispose the needle to Kits-inoperative. position prior to the. lifting of the palletjab'ow, the frame.

3. 1 In a'tileimaking machine, the combination withla table, a frame carried thereby, and a" pallet removably .mounted on the frame and of'a configuration toform a tile htvin a rib alon' its lower side; of means for H ing, the pal etjofi the frame, a treadle mechanism'for actuating said means, a bar movably mounted within the frame, a needle carried thereby "for piercing one of the ribs in the-tile, a plate across the front of'the table, connections between said plate and scribed, theconibination with a table having an opening in its top, rails extending longitudinally along the sides thereof and projecting beyond one end of the same, a frame within the opening of said top and a pallet and shaper arranged in connection there; with; of'a air'of bearings mounted on the table top at one end thereof and just beyond said rails, a crank shaft havin thereof pivotally mounted in said hearings to extend transversely of the rails, a cutter carried by the crank shaft and a supply membenmovably mounted on said rails and ada ted for movement under said crank sha t when the cutter member is' raised to WILLIAM'MELDE.
