Be it fknown that lkirnroirlIiiiiLY,-citiZen of the United' States, iresiding at.=Brooklyn, in the county yof Kings :andi Stateiof New York, .has invented .certain new. and useful- `Improvements in Gaiiri'eis 'forV FineiBricks, of which the following is alspecification.

vcombination and arrangeinentfof partspasf 4will be hereinafter more fully"descnibed,

lillustrated in the accompanying 4draiwiaig land pointed :outin ithe claims. '.Mfy present' design is an `improvement onbthat' fermidisclesed` in the :patent grante'dllebruaiy l 6th 1906, No. 811,844; and it will :be :seen that my present device 'has many advantages over the old form as will be more clearly understood 'by reference to said drawing which illustrates merely an example of means for putting my improvement into practice, wherein F ig. 1 is a vertical longitudinal sectional view, and Fig. 2 is an elevation, showing my improvement applied thereto.

The type of boilers used in most of the power houses in this and foreign countries is known as the BabcoX & VVilcoX boiler. The most important feature in the construction of this type of boiler is the arrangement of the baiiile walls, which deiect the flame from the fire-boX and cause it to pass up and down and around the tubes, s0 that the greatest amount of heat from the combination will be absorbed by the water circulating through the tubes.

Vhen water tube boilers are first constructed, 0r installed, the baffle-plates and bricks are inserted as the tubes are built up and are made to fit tight bythe erecting engineer.

The principal elements of my tool for .iliol'cling, inserting or 'removing `the lire- :bnicks fof water tube boilers comprises a ucarrier, which is vpreferably as wellJ-as :by

'necessity 7a :handle sha-ving iaipair of :gi'ipp'ers lfandimeans forfclamping and releasngia lire# 'lbrick, said ineans lbein'g lpitefeiabl y a. ipair voit?cla-inps ior gnippers projecting from the @handle'fand.'sadapitedy t'o i.engage itwvo of' the corners of a lire-brick, one of said'grippers being :adgustablel with respect to the 'otherl :to `engage and :release:tlieviie-brick; As

:sh'own' the stationary 'member of "the Icarrier :is designated by 3 which consists'iin a flat waarin-4, provided; onA its upper endI with a Jpeculiar'shaped Vgripper 5,' while the lowerAWO jpartof -.said .airin :terminates in'ia boss 6,

which fis proy-idedwith an internal 'zscrew thireadw, which en'gages"\tl1e'aipper part `of :a ftubular member 8, wlnletfatv therV lower end ipiece/ 10, prolvided, @the lower fend of fthe "flatter is yalso ,provided-"with screw 11,

'ithreadech `ibut .in.. an opposite 'direction to,l kthosebef'oife described, tlieobject of which fwiill be ipoiaited leut hcrcinaft'eiz .illhevhand operating member-i110 'has a shoulder'1112Y :at lthev juncture off .the threads :111, ragainst which fa head P13 ioi'lairod=1l vabutts, while below yithe headfris vsecured a? stop plug 15, held secure by screws 16 to the handle .'10,

The upper end of the rod 14C extends through the tubular member 8 and beyond the top of the boss 6, and secured to the same is the movable gripper 17, fastened to the rod which like the upper gripper is adapted to hold a Corner of the line-brick. Thus it will be seen, to grip a brick it is only necessary to rotate the handle till the lower gripper abutt's against the boss 6, then place the tool diagonally across the brick and turn the handle 10, said handle by reason of 'turning it to the right will cause to feed upwardly on the tubular member 8, thereby causing the elevation of the head 13 and elevating or raising the rod 14 up, thus gripping and holding secure the brick between 'the two gripping members 5 and 17. The arm 4 is flattened and provides a substantial support for the lirebrick, so that with the aid of the grippers the lire brick is not only secured to the tool as shown in Fig. 1 but is now ready to be placed in position in the baffle wall.

:said .tubular"member` .is..screwthreaded, as' *75 atf19,`= and terminates into ia' hand: operating The tool with the tire-brick is inserted edgewise by the tool illustrated herein, and the tool and brick are then turned to position, after which the tool is moved along parallel with the tubes until it is in contact with the bathe-plate, when the clamping toolv of the present application may be removed. By means of this tool tire-bricks may be inserted or removed either from below `or from above the bank of tubes.

By the use ot' my tool it is unnecessary to cut or chip any part ot' the brick, as its lines fit all other bricks and the curved parts lit about the adjacent pipes or tubes, by reason of the tubesbeing spread, permits the bricks being placed in position with as much accuracy as when they are originally placed when the baHie-wall was originally built.

The old device accomplished its work very satisfactorily in every respect, but contained many d-etails that I have revised and incorporated herein, for instance it may be stated here that heretofore it has been customary to furnish two sets of tools of each variety for close and distant, work, for instance, when working close to a wall it is impossible to use the usual long handle, so a shorter tool was provided for accomplis ing the work, with my present improvements it is possible with a single tool of each variety the same work be it close to the wall or otherwise may be accomplished by the same, for instance for close Work the handle as shown in Fig. 1 may be used, which is short enough to place a brick in the most closest quarters, while for placing a brick at a distance an extension handle 18 is threaded into the lower end ot' the handle 10, by means of this extension a .tire-brick may be placed at any point above or below the bank of'tubes of the boiler.

lVhat I claim is l. A tool for holding lire-bricks comprising an outer jaw :tormed to receive a portion of the brick, an arm supporting the outer jaw adapted to extend along one side of the brick, a threaded boss at the inner end of said arm projecting laterally of the arm, a movable inner jaw formed as a complement to the outer jaw and adapted to engage an opposite side portion ot the brick, said inner jaw being movable along said arm, a rod movably secured to the inner jaw and extending through said boss, a tubular member threaded into said boss and partially enveloping said rod, a handle member threaded upon the other end of the tubular member and being moved axially ot' the tubular member when rotated on the' threads, said handle member having internally a shoulder, said rod having a head on its outer end adapted to engage against said shoulder, and a removable plug in the hollow handle member adjoining the shoulder for abutting against said head.

2. A tool for holding lire-bricks comprising a pair of relatively movable complemental jaws for grasping a fire-brick, a tubular member rigid with one jaw, a rod rigid Iwith the otherjaw and sliding through said tubular member, a handle threaded for rotation and axial movement upon Vthe outer end of said tubular member, said handle having an internal shoulder, said rod having a head adapted 'to take against said shoulder, and an abutment in said tubular handle for striking against said head.

In testimony whereof I art'tix my signature.
