town, in the county of York and U? s of 5 Pennsylvania, has invented certci-n no ,v end ALI! useful improvements in the A .c

which the follownig is for -Brick-Mechines, of a s 3 cificotion.

his invention relates to that class of lo brick machines known as soft mml or green brick machines.

v I In the manufacture of briclsze from soft mud, meteriol difficulty is experienced loosening the brick from the molds so that v5 they may be dum rod out onto the receiving pellets. The Inc ds n'r'ust be more or less violently agitated by lznoclf'zg or clicking, so as to loosen the green bilcli, but ii this carried to excess the mud will move toward one or the other side the mold, so that the bricks lose their rectangular form endv must be thrown away.

The only really satisfactory methods so for known to me of accomplishing this result is by the employment of manual labor, the molds being taken from the machine by Workman and violently agitated to loosen the brick. This operation, however, is one requiring considerable skill end the exercise of great strength, iuosnmch as each mold contains six or more bricks and is quite heavy, While it is almost impossible for e single Workman to keep up with the output of the machine.

5 Attempts have been made to accomplish the loosening of the brick-by shaking or agiteting devices, one of these being in the "form of e mold carrying table which is egi tatecl through the medium oi stepped coin,

\ but it has been found, by actual test, that the movement imparted by the cam is not suiticientiy rapid and abrupt to do the work desired, and thesemachines have therefore 'not been adopted.

In other machines, stationery bumpers or knockers have been-em iloyed end the mold box reciprocated between them by workmen, while in other cases the mold box has been held stationary and manually oereted knockers have been'em ployed. So Far as I am aware, however; there is no machine ct present in use in which the green brick is successful] loosened from the mold by mechanic means. The main object of the invention is to enable the v ii men of the necess ry insul'licient physical st A further ob vitle e debris simple and co Jh shall l e oil o omlv construction end whiclrroey be clil'y app" 1 to existing brick rocking mo. ery.

A further object o; the invention is to provicle e mold shaking or og'itoll lig device in which the mold is loosely mouiiited on :i' ieciprocetory table that may be operated at enyspeel'l, the movement oi the mold i. each direct on being obru tly stopped oy e kneel? r or boomer which, otter o. nlunbci' of operations, "will Without injuring its oi-is-pe.

With these end other objects in vi"- v invention comprises the various novel tom tercs of construction and combinetion of ports, which will he hereinafter more fully described end pointed 012i osrticulsrly in the conceded cleinis.

Figs. 4.- sncl 5 are views corzwspontling to Fig. 1 illestrc-tii'ig modifications oi the invention, ello 'iting it tomechines of e clitl'erent type then the one shown.

Corresponding parts in the several ii urss are i'nlliceted. throughout by similar chorecte'rs of reference.

The working ports of the xnnchiiv- 2 mounted in o. suiteble frame whi rosy be formed oi wood or motel, and which in cludes in its construction it horizontally (lisposed' table 11 over which the mold boxes 12 pass. The mold boxes are successively moved under s. hopper 13 through which the clay or mud is forced for the purpose of fill ving the mold, and the molds pass from under the hopper, they ore moved in successivc order onto it laterally reciprocating table 14. I

The table 14- is of a length'siigh-tlyl less than that of the mold box, and is mounted "for rociprocotory movement on o plurality of m.iti-;triotion rollers 15 that are carried-$93 ellectuell'y loosen the brick ends with transverse y disposed'hanr movement or" t 1e mold box will Wherepins, or illustrated in Figs. 4 and ad3ustthe platform is secured a bar 16 from the ends of which project horizontally disposed tongues lithot enter Ways or guides formed in the frame, these being for the purpose of preventing abnormal movement or jump of the platform While inoperation at the end of a stroke. These guides F re formed in the instance shown by chambering the side rails of the frame, and securing cap .blocks 18 thereon as shown.

From the bottom of the bar 16 extends a yoke 18 having a vertically elongated slot 19 in which lite an anti-iriction roller 20 that is rarried by a crank pin 21. This crank pin is carried by s disk 22 that is secured to a horizontally disposed shaft 23 journaled in the frame, and the disk is provided With-a number of openings 25 spaced at unequal distances, respectively, from the axis of the shaft 23, and arranged to receive a crank pin 21, so that the pin may be adjusted in any one of these openings for the purpose of altering the throw of the crank. I

The mold lJOX -l2 herein illustrated is ofthe ordinary type, being )rovided at its opposite l le bars said mold is free to slide to a limited s; but on the platform 14. The extent of this movement is limited by the transverse strips 27 that are secured to the top of theplati'orm at points shghtly beyond the ends cl the bottom or the mold box.

Secured to the opposite sides of the frame are knocker arms 28 which preferably are formed of metal andwhich are disposed in the path of movement of the handle bars 26 or some other rigid pert of the mold box.

in the operation of the device, the shaft rotated at any desired speed to impart .en to eleven reciprocations of the mold for each reciprocation or the plunger Within the hopper and this movement istransmitted through the crank pin and its previohsly described connections to the platform 14-. A mold box carried by the platform will be moved between the knocker arms, and the handle bar at one end or the mold box will engage the adjacent knocker arm just before the crank; c'om letes its stroke so that the be abruptly stooped While the platform will continue to more for a short distance in the same directioni As the crank pin passes over the con ter, the direction of movement of the platform will be reversed and the mold bOX'Will be moved in the opposite direction, until the other handle bar strikes the otherknocker arm, where the o oration is repeated. This may be continue for any desired length of time until the green brick is loosened, eiter which the mold box may be liited oil and inverted in order to dump the brick onto the receiving pallet. V

The attachment herein described was particularly designed for use in connection with the Henry Martin machine, but to adapt it for other known machines, I have illustrated in Fig. 4 and 5 to this end.

in the modified construction illustrated in Fig. i, the crank disk 22 is located at one side of the machine, and is connected by a pitman rod 30 to an arm 31 that extends laterally from the bar 17 of the platform. in the construction shown in Fig. 5, the crank disk is connected to the bar 17 by means of an angulerly bent connecting rod 32. In both of these cases, however, the operation is the same as described in reference to Fig. 1, the crank being used as a-means for effecting the reciprocating movement of the platform while the'knocker arms serve to abruptly stop the movement of the mold box.

in some instances it will be found expedicut to adjust the reciprocating table ver tically, and this l provide for by mounting the rollers 15 on stands 15* projecting from brackets, the latter being slotted vertically,

as shown, and secured to the frame of the machine at desired oints by manipulation of the securing orc ampin'g bolt, as will be understood.

It Will be observed that in all of the construotions described, the operation of the platform properis not one in which the opera-ting mechanism is subjected to undue jar.

or strain, inasmuch as the crank will com- 'plete its stroke Without any stopping or abrupt movement the operation being as smooth and regular as that of any ordinary crank motion, so that there is no danger of wearing out these parts or danger of acci dental breakage, such as is likely to occur in machines Where the operating parts are abruptl y stopped and started into operation.

'io admit of removal and replacement of 4 the platform, or the substitution of another form, I chamber the top side rails ofthe frame, 0 posit-e the rolls15, and after in-v sertion o a platform and adjuncts I secure the same by the stay blocks.

1 claim p 1. in a machine of the class described, a reciprocatory glatform, a crank V throu h which elongate motion is imparted to said platform, mold box guard stri s secured to the platform, and stationary mocker arms dis need in the path of movement of the mo d box and arranged to abruptly stop the same Without interfering with the movement the platform.
