VENEERING- APPARATUS.

Application fi1ed August 23, 1920. Serial No. 405,398.

which facing of diiferent character fromthe' body of the brick maybe applied thereto. The body may be made of material having certain mechanical and commercial advan- ,tages other than its ornamental appearance, while the facing which is to be exposed may be formed of material best serving for: protection against the elements, ornamentation, or any other desired characteristics.

This invention relates particularly to a construction wherein there is a mold box fed with material for the bodyof the brick and mechanism adapted to] feed facing material to the box in position on the blocks body, the pulp then being cut oif to complete the block. Itis the primary object of this invention to provide a structure of the character described, which is simple, durable, operates u ner, is easi operation.

y manipulated, and is speedy in These objects together with other objects and corresponding accomplishments are chtained by means of the embodiment of my invention illustrated in the accompanying drawings, in which:

Fi ."1 is a side elevationof a complete machine; ,Fig. 2' is aplan view ;5Fig. 3 is an enlarged section takenon the line 38 of Fig. .2" showing the measuring means for dispensing the faclng material; Fig.

' i is a section as seen on the line 4-4 of Fig. 2; Fig. 5 is a section as seen on the line 55 of Fig. 1; 'Fig.' G'is an enlarged section as seen onthe' line 6 '-6- of Fig. 4; and-Fig. 7 is an enlarged fragment of a portion of the machine as seen in Fig. l, but with the cut-off plate in a difierent [position Referring moreparticularly to the drawings, A indicates a frame, the details of corn struction of which are not important and may be varied to suit conditions. 13 indicates generallythe pulp feeding and mold-,

ing mechanism for the body of I the block.

pon the pulp in an efficient man The mechanism for measuring and feeding the facing material for one side of the block is indicated-by C. A similar mecha nism for feeding facing material for another'side of the blockis' indicated' by D.

.The' gearing for operatingthe several movable parts of the machine is indicated by E. A mold box for the block is indicated by F.

The structure for feeding the pulp for the'body of the block will first be considered. Mounted upon the top of the frame is a pulp receptacle '8. Communicating therewith is a vertical chute 9. This chute is of the horizontal cross section of the body of the'block to be formed and tapered from top to bottom, the bottom being larger. Disposed within the receptacle Sand at the bottom thereof is a stirringimpeller 10. The

arms of thisimpellerwillslide across; the top of the chute opening. The impeller insures the feeding of pulp to the chute 9, the I pulp not flowing easily' The impeller is driven from a shaft 11 journalled in the bottom ofthe receptaclel It willbe noted that there is a clearance between the chute and mold boxF on two of" its sides. This clearance is sufiicient 'to provide for the facing material. Y j A Disposed .onan extension'of the frame is a hopper 12 forfacing pulp. The hopper is provided with ahslidingbottom guidedon ways 13, see Fig. The bottom consists of a plate lt havinganopening l'ii overhung by a sheariGJ. Extending from the top of the shear is a wall 17v parallel to'the bottom plate 14:. k The pulp hopper 12'is intended to be filled, withpulp and thebottom reciprocated. One end of thepath oftravel of the bottom is such "thatthe shear16 is at one side of the receptacle. The'other end of the travel is at or adjacent the other side. As the bottom is moved from the position shownin' Figs.' 3 and 4;, alayer of facing pulp will be sliced off and delivered intothe chute lSklispOsed 'therebeneath. For this purpose ofreciprocating'thegbottom, it is provided with a bracket 19 to which is piv- "otally connected alink 20. The link 20 is connected to a crank arm 21 fixed to a shaft 22 journailed in the frame. The shaft 22 has secured thereto a crank arm 23 secured by a connecting rod 124 to an oscillating member 25 .pivotallymounted upon the frame. The oscillating member has" an elongated slot through which passes a bolt 26 securing the connecting rod thereto. This construction provides for adjustment of the connecting rod and variation of the travel of the shear l6 and consequently the amount of facing material disposed. The oscillating member has an opening in which is dis posed a pin 27 mounted upon a drive pulley pulley 28, the pin va bevel pinion 80 meshing with a bevel pinion 31 mounted on shaft ll, whereby the impeller is driven. The pulley 28 may be connected'to a drive pulley or any. mechanism serving as a source of power. Upon rotation of the pulley 28, the oscillating member 25 Will be rocked and the bottom 1-1 of the hopper 12reciprocated.

Mounted upon a sub-frame extending to one side of the main frame is a hopper82 similar to hopper 12. It is also provided with a sliding bottom 33 constructed similar to the sliding bottom 14:, with a shear St for the purpose of slicing off pulp and delivering it'to an inclined chute 35. A link 36 connects the bottom to a crank arm 37 mounted'upon a shaft 38 journalled in a frame. Fixed to the endof shaft 88 is a bevel pinion 39 meshing with a bevel pinion 4O fixed to shaft 22. Shafts 22 and 38 being geared together, the bottoms of the

hoppers

12 and 34 will be moved at the same time and facing material sliced off and-fed to their respective chutes.

Slidably mounted over two side sof the chute is an apron 41 adapted to be moved into the mold box F, and thus space the body of the block from the sides of the mold, so as to permit the introduction of the facing pulp. A bracket 42 is mounted on the apron and has secured thereto by pivotal joints lever arms 43. The lever arms are pivotally secured to the frame at 142. Fixed to a shaft 45 and disposed beneath thearms 13 are cams so to raise and lower the arms,

and thereby raise and lower the apron.

Closing the bottom of the chute 9 is a plate 47 arranged to be reciprocated so as to open and close the bottom of the chute. The plate 4:7 is pivotally secured by a link %8 to the frame.

Plate 47 is provided with an abutment 50. Mounted upon shaft 45 is an arm 51 adapted to engage the extension d9,"

swinging the link 48 and reciprocating the plate 4,7 so as to open the bottom of the chute, then engaging the abutment 50 and moving the plate 47 so asto close the bottom of the chute. Shaft 45 has a gear-52-se cured thereto meshing with. a gear 58. Gear 53 is secured to a shaft having a sprocket Wheel 5 f mounted thereon. Sprocketwheel 54 is geared by a chain 55 to a sprocket fixed pulp thereto for the body of a block, an

box,

on shaft 29. Thus, the moving all driven from pulley 28.

The parts of the apparatus should be so arranged that the plate 47 closes the chute, the apron 41 is first dropped into position in the box, the facing material then sliced from the hoppers so that it will slide into position as indicated in Fig. 7 and thereafter the plate at? moved into position opening the bottom of the chute so as to deliver the body pulp to the box. The apron should then be lifted and the plate 4t? moved to close the chute and divide the pulp, and-the mold box with its block removed and another substituted. This cycle of operations isjthen repeatech I What I claim is:

1. In a .veneering machine, the combination with a mold box of a chute .to feed parts are apron movable into said box to provide a facing svace therein a ho) er for facin material, meansto deliverfrom said hopper to said faeingspace a quantity of facing material, means to open said chute to said and means to successively move said aproln into said. box, deliver facing material of substantially the same dimensions as said facing space thereto and open said chute.

2. In a veneering machine, the combination with a mold box ofmeans to'feed pulp thereto for the body of a block, an apron movable into said box to provide a facing space therein, a hopperforfacing material having a slidable bottom provided With a shear to slice a measured quantity substantially of the same dimensions as said facing space of pulp from; said hopper, a chute for delivering said facing material to said facing space, and, means to successively move said apron into said box and deliver said facingv material thereto. I

3. In aveneering machinepthe combination with a mold box ofa chute to. feed pulp thereto forthe body of a block; an apron movable into said box to providea facing space therein, a hopperfor facing material having a slidable bottom provided with a shear to slice a measured quantity of pulp 115 from said hopper, a chute fordelivering the facing material tosaid facing space,

space, means to, dispense facing material to said chute in a layer of substantially the same dimensions as said facing space, and means to successively move said apron into said box and dispense said facing material.

5. In a veneering machine, the combina tion of a mold box With'a chute to feed pulp thereto for the body of a block, an apron slidably mounted upon said chute and movable into said box toprovide a facing space therein, means to open said chute to said 10 box, a facing chute communicating with said facing space, means to dispense facing ma terial to said chute in a layer of substantially the same dimensions as said facing space, and means to successively move said apron into said box, dispense said facing material and open said chute.

In Witness that I claim the foregoing I have hereunto subscribed my name this 13th day of August, 1920.
