To .all whom t may concern lBe it known that I, HOWARD K. KING, a

" Citizen Of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a `new and useful Cut-Oft' Mechanism for Brick-- Machines, of which the following is a specication.

My invention rela-tes to wire cut-off mech? anism for brick machines and the like.

The object of my invention is to provide improved means for supporting and moving a cut-off wire through the bar during the travel of the bar and in a plane at the required angle to said. direction of travel.

.My invention comprises improved means for movably supporting the wire supportT ing and actuating mechanism so that the same shall have a reciprocating movement,

said movement in one direction being withV the movement of the bar.

My invention comprises automatic means for controlling said movement by the variation in speed of travel of the bar. i

My invention comprises automatic means whereby the eiiciency of the helping power communicated to the moving clay bar shall be affected by the variation in the force .eX- erted by the clay bar itself.

This invention relates to an improved cutoff for brick machines. It is applicable to brick machines in many respects similar to that shown in patent to King and Chambers No. 678,259; July 9,Y 1901. f

The bar of clav is delivered to the regulating belt 25 in the usual way. The shaft 27 of the regulating pulley is operatively connected with gea-r 28 through two universal .joints 29, one being shown in Figs. 2 and 3, and both being shown in Fig. 23. These universal joints are introduced ,to permit a translative movement of shaft 27 with re- -spect to the shaft portion of gear 28, which rotates in a fixed bearing, for the purpose hereinafter explained.4 `The gear 23 coperates with pinion 30 ony shaft 31 provided with the beveled gear 32, which coperates with beveled gear 33 on shaft 34, see Figs. 2 and 3, Shaft 3ft also carries gear 35, which is connected, through the train of gears 36 and 37, with the gear on one fric- 'tion element 33; the other ycoperating fricthrough the gears enumerated, to the regulating' pulley 26, to cooperate with the force exerted by the moving bar of clay. Upon the shaft 34 is also provided the gear 41, which cooperates with teeth on the wire ring 42, see Fig. 3, which carries the cutting` wire 43. On shaft 31 is carried the cam wheel 44, which cooperates with the roller 45, see Figs. 1 and 5, for the purpose hereinafter explained.

Regulating frame- The regulating frame 46 supporting the regulating belt 25 and pulley 26, is mounted on four ball bearings 47, such as are shown in detail in Figs. 18, 19 and 20, at approximately its four corners. This permits a slight longitudinal movement of said regulating frame, controlled by the fluctuations in the movement of the clay bar. The movement of the frame 46 is communicated, through bracket 48, see Figs. 1 and 16, to lug' 49 on lever 50 pivoted at 51 and secured at 52 to a thrust box 53 in which rotates the collar 54 secured to shaft 40 by the pin 104. In this way the movement of the frame 46 affects, through the shaft 40, the efliciency of engagement between the friction elements 38 and 39. 1t is to be understood that the shaft 40 and element 39 always run at higher speed than element 38, and that therefore there is always a slip between elements 38 and 39. The tendency of the acceleration of the movement of the clay bar is to push the regulating frame forward, which, in the manner above explained, serves to increase the efficiency of engagement between the friction elements, and consequently the helping effect of the driving shaft 40 upon the regulating pulley 26.

Arbitrary control-The arbitrary control Of the adjustment between the friction elements is secured by the hand lever 87, see Figs. 17 and 18, secured to the lever 50 which carries the lug 49 and operates automatically as above described. One of the purposes of the hand lever is for transferring power to the regulating pulley at the beginning of the operation of the machine, before the clay-bar exerts its power.

Preliminary adjustment/. The preliminary adjustment between the friction elements is secured by the following mechanism: rllhe threaded sleeve 99 is secured to the shaft 40 by the pin 100. IThe collar 101 has a threaded end for cooperating with the threaded sleeve 99 and is adapted to abut at its other end against the friction element 89. By turning collar 101 in one direction or the other, relatively to sleeve 99, the proper normal adjustment of element 39 is secured. The holes 102 are provided for engaging the wrench or Spanner used for turning said member 101. The lock nut 103 is provided for maintaining members 99 and 101 in said position of adjustment. This method of adjustment is provided for the original assembling' and also for taking up the wear between the friction elements. A further preliminary adjustment, with respect to the tension exerted by the regulating frame on friction elements 3.8 and 39, is secured by the hand wheel 55, see Fig. 3 threaded on the rod 56 which is secured atthe stationary point 57, so that the hand wheel will engage the bracket 5S which is secured to the regulating frame 46. lt is to be understood that this adjustment is a very fine one, so that the slightest fluctuations of the rate of travel of the clay bar will affect the tension between the friction elements, so that the efficiency of the helpving power communicated to the' moving clay bar shall be affected by the variation in the fo-rce exerted by the clay bar itself.

Anti-friction bearing 0f friction elements-Since itI is desirable to secure the full advantage of a nice adjustment between the friction elements 3S and 39, it is important that this result shall not be counteracted by other frictional conditions. For example, when member 39 is forced into tighter relation with member 3S, which members always have a slipping engagement with each other, the tendency is to cause the transference of greater power from 39 to 38. By forcing 39 against 38 however, 38 will naturally be forced with greater efficiency against its thrust bearing, and, if special provision was not provided, a resultant greater friction would. be caused between said member 38 and its thrust bearing, which would in a large measure, overcome or counterbalance the result of the delicacy of adjustmentbetween said nembers 38 and 39. I therefore provide the ballbearings 116, see Fig. 16, so as to reduce to a minimum the friction between said member 38 and its thrust bearing. Since the regulating belt, regulating pulley and regulating frame also enter into the automatic control of the said friction elements, it is desirable for the same reason to eliminate disturbing frictional conditions with respect to these instrumentalities. The regulating belt is under considerable tension and is required to sustain the great weight of the long bar of clay. 1 therefore provide ball-bearings for the regulating pulley 26 shown in Fig. 24, and ball bearings for the roller 91 at the other end of the regulat-` ing belt as shown in Fig. 25. mount the intermediate supporting rollers 89 in arguto or improved wooden bushings which greatly reduce friction without lubrication. As has already been stated, the regulating frame is mounted on ballbearings at its four corners.

Wir@ wLeeZ.-The wire wheel 42 has a. peripheral engagement with the rollers 59,

60' and 61, by which it is supported, see Figs. 2, 4 and 6, and as already explained, is driven by the gear 41. The wire wheel carries the wire 43, extending diametrically across it, secured at'one end to the fixed stud or hook 62 and at the other end to the hook 63 carried at the free end of the composite spring 64.

Roller supports-The rollers 59, 60 and 61 are all supported on a framework, which comprises the beams 65 and 66, see Figs. 3 and 4. These beams are pivotally mounted at their 'outer extremities on the levers 67 connected with the rock shaft 69, while lever 68 rocks on shaft 70, `which has a pivotal connection with the stationary framework.

Aczuatioa of wire wheel supporting frame-As above pointed out the cam 4 4, on

shaft 31 is in operative relationship with the regulating pulley 26. This cam 44 coperates with the cam roller 45, against the tensions of springs 71, to actuate, through rock arm 72, the shaft 69, to rock the lever 67. This resultsin the reciprocating movement of the beams 65 of the framework supporting this rollers 59, 60 and 61 and the wire wheel.

The formation and operation of the cam 44 is such, with respect to the other operating mechanisms of the machine, that the supportingV mechanism of the wire wheel will have a reciprocating movement, said movement in one direction being in the direction 4of the movement of the clay bar and at the same rate of speed, said movement with thev clay bar beginning before the wire engages with the bar, and continuing until it shall have passed through the clay bar, due to the rotating movement of the wire wheel. Aft-er the wire has passed through the clay bar, the wire wheel sup-l porting means will be returned to initial position to repeat the operation. It is also to be understood that the bottom slit plates 73 and 74, the side slit members 75 and 76, and` associated mechanism are all supported by and move withv t-he framework supporting the f wire wheel.

t is to be noted that the three rollers 59, 60 and 61 are split rollers, one section or element provided with an adjusting screw 77, see Fig. 11 to maintain the required distance between the two sections to maintain a perfect t betwen the said roller .elements and the peripheral channel 78 of the wire wheel 42; adjustment being made from time to time to take up wear. These rollers are for instance, feathered on the shaft 79 and the set-screws 80 coperate in maintaining their proper positions thereon.

Wire supporting mecham'sm.-The pin or stop member or* stud 81 is secured to the. ring 42 and is provided'with shoulders 82.

toengage;thebifurcated end' of spring 64 to limit its outward movement. V The said that the bifurcated end of the longestmember straddles'the pin 81. and 68, see Figs. 4 and 11. The lever 67 is j tion'of the supporting mechanism for side ,slit members7 5 and 76 is shown in Figs. 12 Iandl. The bar 105 is provided with the :slot 106 through which is secured the bolt i107 for the adjustable engagement of said vbar 105 with the framework supported by fthe lbeams 65. and' 66. Upon this bar 105 .is pivotally mounted at 108 the bracket 109 which carries slit member 75 or 76, as the .Side .slit members' support-The construccase may be; that is to say, the supporting structure'of each member is substantially the same. To a free end of bracket 109 is secured, at 110, one end of a slide rod 111,

carrying the spring 112, for normally maintaining the said member 75 in the vertical yposition against a fixed stop 117 on member v105. that when the wire encounters a stone or otherl obstacle in the bar, the members 75 -and. 76 will swing back to permit the escape By this construction it is provided of the same beneath them.

Wire alarmen- In connection with the 4same supporting mechanism is provided a clamping device 113 of suitable formation, shown in Figs. 12 and 13, carrying thevstripl v114 of flexible material such as felt or rubber, projecting slightly into the path of :travel of the wire 43, for the purpose of wiping therefrom any substances which might otherwise stick vto the wire. The plectrum 115 also extends across the path of travel of the wire, to vibrate the same, as va further means for freeing it from substances that would otherwise cling thereto.

Regulating from@ rcom'fractiew--The regulating frame comprises the wooden beams 88 which are bolted to the angle irons 46. In

the beams l88 are inserted the arguto or im-V proved wooden bearings for the rollers 89 supporting the regulating belt and to the beams 88 are also secured the brackets 90 forming a part of theVv ball-bearing support of the frame as indicated in Figs. 19 and 20.

Adjustment of regulating' mdrr-The roller 91 supporting the other endof the regulat-V the screw- 95 which is threaded in the lug 96 which is connected with the frame comprising the angle irons 46, see Figs. 1 and 17. A hand wheel 97 is adapted to operate the screw 95 through the beveled gear 98 to secure the proper tension of the belt.

Carrying-oy' belt cmd bz'furcated slit filata-As will be seen by an inspection of Fig. 3, the carrying-olf belt 118 is narrower than the regulating belt 25. As a matter of fact it is considerably narrower than the length o-f the bricks delivered thereto. It will be remembered that the slit plates 73 and 74 are reciprocated with the cutting mechanism, and therefore plate 73 moves toward and away from belt 118. As the severed bricks are being pushed across said plate 73 it is important that they should not be caught between any undue space existing between said plate and the carrying-otf belt. For this reason the plate 73 is made with wings or extensions flanking the belt 118 so that as the bricks are pushed over this plate they are supported by the wings until they are safely engaged by the belt 118. It will be noted that the top of plate 73 is approximately flush with the top of belt 118, and as the bricks are pushed along over plate 73 they are safely landed on belt 118 without any shock or jar.

Operationlt is to be noted that the wire engages the clay bar at an angle with the to-p plane and the exposed side of the bar as will be evident from an inspection of Fig. 2. That is, the wire enters the top and left side of the bar always moving inwardly into the clay bar until it reaches the slit plates. This results in a smooth clean cut at the margin of the bar, without making ragged edges, whereas if the wire left the bar moving outwardly through the surface, except where protected by the slit plates, a ragged or feathered edge would be left. The course of the wire through the bar also assures the carrying of any hard obstruction such as a stone, safely over the bottom slit plates, and safely under the spring controlled side slit plates.
