relation; and Fig. 10 isa sectional view ill'us'- tratlng details of the mold construction;

The invention, in the form thereof illus trat'ed in the drawings, comprises the trusses 1 connected by cross beams 1 '1', 12, and 1 providing a maincari-iage' frame, the latter being carried by the traction-wheels 2 movable on rails 3 which are supported by beams-4. 7 Y

A motor5, vertically adjustable by liners 5' upon its supporting cha'ir 1 .ontheframe,

has, on its shaf-t- 5 thepull'eys5 which are connected by respective Belts 6 withpulleys'7 'fixed on respective shafts 7- jour Gear wheel's7", fixed onthe respective shaftsa 7, engage gear wheels 8*,fixed on the respective shafts 8, which are journaled in the frame. Pulleys 8; fixed on one of theshaftsfigarecon nectedby a straight belt-'9 anda twisted belt- 9 with pulleys 10 and 10"" on a shaft 10' journ'aled inthe frame, the pulley 1-0 being an idler running loose between the pulleys-10 fixedto the shaft. A belt shifter 11- is adapted for moving'the belts 9 and so that they are alternatelyengaged with the idle pulley 10 and one or the other of the fixed pulleys 10 to drive'the shaft 10 in opposite directions. A gear wheel 10 'is fixed on theshaft 10 and engagesa: gear wheel 11 fixed on a shaft 11 which is jo'u'r-' naled in the frame. A gear whe'el 11 is fixed onthe shaft 11 and engagesa stationaryrack12.

It will be understood that the motor 5 acts, through the intermediate mechanism.- described, upon the rack 12 to reciprocate the carriage, the latter being moved in reverse directions by shifting the belts so" thatthey drive alternately.

The shafts 8 have fixed thereon :eccentrics 8 which revolve in the respective"rings13 of the eccentricrods 'l3,' and these eccentrio rods are connected by pins 13" with guide heads 14* in'which are screwed rods- 14. The rods 1 l are provided with heads 14 which have a limited movement in-the tubular'stems 14L" of therammers 14. Thestemscontain the springs le 'for providing a flexible relation betweenthe parts'14 and 14 and for moving the stems 14 down on the heads 14 until the latter are engaged by the collars 14 fixed to the tops of the sleeves around the rods 14.

Vertical guides l are fixed at their tops to a plate 1 carried by the beams 1 and 1, and at their bottoms to beams 1 fixed to a rectangular frame .1 the latter being supported by the angles 1 depending from the main frame and having their tops fixed to the parts 1 thereof.

Liners 14 are adjustable by the set screws 14 within the guides 1 and serve to control the actions of the heads 14", which run therein.

Shafts 15, journaled in the frame, have eccentrics 15 fixed thereon and revoluble in rings 16 on the eccentric rods 16. The rods 16 are connected by the respective pins 16 with rods 17, which reciprocate in bearings provided by arms 1 on the guides 1 and reciprocate the rods 17 having the slickers 17 fixed thereto. The rods 17 are provided with flanged heads 17 which are supported in cups 17 fixed to the rods 17, balls 17 being disposed within the cups to take the thrust and facilitate the rotary ac tion of the shafts 17.

Bearings 1 are fixed to the members 1', and beveled gears 18 are provided with tubular journals 18, which are splined on the shafts 17" and swiveled in the bearings 1 Beveled gears 19 engage the gears 18 and are fixed on shafts 19 journaled in the frame, the shafts having sprocket wheels 19 fixed thereon Chains 20 and 20 connect the wheels 19 with sprocket wheels 7 fixed on the respective shafts 7.

It will be understood that the action of the motor 5 revolves the shafts 7, through the intermediate mechanism described, simultaneously with the movement of the frame, and the shafts 7 act, through the intermediate mechanisms described, to reciprocate the rammers 14 and .revolve the slickers 17 l 7 As it is desired that in their movement with the carriage, the slickers 17 ahead of the respective rammers 14 shall be elevated and those in the rear shall be lowered, the shafts 15 have fixed thereon the ratchets 15 and journaled thereon the gear wheels 15 provided with pawls l5 adapted for engaging the respective ratchets. The ratchets 15 and pawls 15 on opposite sides of the respective rammers 14 are oppositely disposed so that the forward slickers 17 in the respective movements shall be positively connected with such wheels. These wheels 15 engage stationary racks 15 fixed to the frame members 15, whereby the reciprocation of the carriage effects a predetermined vertical movement of the respective slickers 17, by the mechanism described.

In order that the respective slicker mechanisms shall be brought into correct position for moving them downward at the beginning of the movement requiring their respective operations, each shaft 15 has fixed thereon an arm 15 which makes contact with an arm 15 journaled on the frame and normally pressed against the stop 15 by a spring 15. The corresponding eccentric 15,is moved beyond its required position in elevating its slicker mechanism and, in this movement, the arm 15 bears against the arm 15 which rocks against the action of the spring 15 and the spring recoils to move the arm 15 back to effect the desired adjustment of the eccentric when the corre sponding wheels 15 are moved by the carriage out of engagement with the corresponding rack 15. V V e The carriage moves the slickers 17 and rammers 14 longitudinally over the stationary beds or anvils 21 across which, beneath the ramming and slieking devices, molds 22 are carried by link belts23 which pass over the wheels 24 fixed on the journaled shafts 24. The wheels 24 are operated by gears 24 respectively journaled on one of each pair of the shafts 24 and having thereon pawls 24 which engage ratchets 24 fixed to the shafts. Gear wheels 25, fixed on the journaled shafts 25, engage and oscillate the wheels 24 The wheels 25 are oscillated by reciprocating racks 26 operated by links 26 and levers 26, the latter being rocked on the fulcrums 26. Cross heads 27, which reciprocate in the vertical guides 28, are provided with'pins 27 which are engaged in the slots 26 of the levers 26, by which the latter are oscillated.

Eccentric rods 29 are connected with the cross-heads 27 by pintles 29 and with gear wheels 30 and 30 by the eccentric pins 30. The wheels 30" and 30 are fixed on shafts 30 journaled on the beams 4, and are turned a half revolution, by the complete movement of the carriage in each direction,

through the engagement of the racks 1 on the carriage with the wheels 30 and the engagements of the wheels 30 with the wheels 30". r

The cross heads 27 of the respective cross head pairs are moved by the rods or links 29 simultaneously in opposite directions, and these movements of the cross heads oscillate the respective levers 26 in opposite directions so that the respective sets of wheels 24 are advanced alternately and move the respective molds 22 intermittently a distance equal to the space between them, into registration with the bed 21.

The heads 27 are connected with respective heads 31, movable in the guides 28, by bolts 32, movable through the heads 27, the bolts having the coiled springs 32 dis posed thereon between the heads.

Plungers 33 are fixed to the heads 31 for pushing the bricks out of the molds 22 upon the pallets 34, which are carried by the tables 35 movable vertically in the guides 28, the tables being normally elevated by levers 36, provided with the counter-weights 36, and having the fulcrums 36 Sand boxes 37 are movable vertically between the struts 21 which support the bed or anvil 21, by levers 38 having the fulcrums 38. These levers are rocked, to elevate the sandboxes and sand the molds as they rest between the uprights 21%, by the contact therewith of the parts 39 which are movable in the ways 28 on the members 28 by the heads 31, the heads being connected to the parts by the pins 31,

The molds 22 are provided with bottoms 22 fixed to the belts 23 and pintles 22? by which the bodies of the molds are hinged to the bottoms, the bodies being normally held against the bottoms by the catches 22 and the 'coacting catches 22" of the bottom bolts 22. The bolts are movable longitudinally in ways 22 on the bottoms and are retracted bv coiled springs 22 connected therewith and with the pins 22 fixed to the bottoms. As the belts 23 move the molds 22 from the anvils 21 and downward over the wheels 24:, lugs 22 on the bolts are engaged by springs 40 while the molds are in substantially ver-.

tical position between the standards or guides 28. The bolts are thereby held as the moldsmove forward, the catches 22 are disengaged from the catches 22", and the bodies of the molds are turned by gravity on the pintles 22 through an angle of approximately 90 degrees, onto the pallets 34, where they rest while the plungers33 move downwardly through them. The bricks are thus discharged from the molds upon the pallets andthe tables 35 are moved down thereby against the actions of the weights 36, being held down by the engagement therewith of the latches 35 until such latches are disengaged. 7

In the further forward movement of the belts 23, the studs 22 of the mold bodies engage the cam ways 41 and move such bodies into engagementwith their bottoms 22, where they are held by the engagement of the parts 22' and 22". i

It will now be understood that, in operation, the motor 5, which is adjustable ver tically to maintain the desired tension in the belts 6, drives these belts and the wheels 7 constantly, these wheels acting through the intermediate mechanisms described to drive the belts 9 and 9 constantly. The belts 9 and 9' arealternately engaged with a pulley 10 by operating the belt shifter 11, and the carriage is reciprocated by the engagement of the. gear wheel 11 with the rack 12 through the mechanisms connecting the wheel with the pulleys.

The shafts 7, which are constantly re- 1 reciprocating rammers as they are moved,

over the molds as the latter rest on the beds 21 in the step by step movement of the belt 23, each maul moving over and acting upon sand in two sets of molds 22 in the form of the machine illustrated.

Thedescribed movements of the carriage revolve the gear wheels 15 through their engagements with the stationary racks 15, and, in the alternate movements of the carriage, the respective forward slickers, which have been elevated at the end of the reverse movements, remain in the elevated position, because the pawls 15 of the corresponding gears 15 move backward idly over the corresponding ratchets 15 17 are, however, moved down into the plane of the tops of the molds by the positive engagement of the corresponding pawls 15 with the ratchets 15 the racks. being of such length and so disposed as to effect-a half revolution of the respective eccentrics 15 of the slickers to be elevated at the approximate limits of the movements of the carriage.

. The constantly revolving shafts 7 act through the intermediate mechanism described to revolve the slickers 17 constantly, with the result that those in the lowered position in contact with the consolidated material in the molds smooth the surface of thematerial as they move forward over the molds. f

The movement by the racks 1 of the wheels-30 due to the reciprocation of the The rear slickers carriage, e fiects the reciprocationin alter- I nate directions of the heads 27 of eachpair' of these heads, whereby the corresponding levers 26 are oscillated in opposite directaining sand that has been rammed and smoothed are moved from'the beds 21 over the forward wheels 241 adjacent to the guides 28. In passing to this p0sition,the

boltsv 22 are disengaged by the springs 40,

the bodies of the molds are turned down.

upon the pallets 34, and the heads 31 are moved down, by the heads 27, to cause'the' plungers 33 to push the bricks through the umolds, onto the pallets and effect the engagement-ofthe thus lowered tables 35 by the latches 35,'the bricks being removed from r the table inthis position thereof;

The bricks having been moved out of the path of the molds 22, the belts 23 move forward and the bodies of the emptied molds are reengaged with their bottoms 22* by the engagement of the studs 22 thereon with cam ways 41.
