Appncaaaneaaugust-2o, 1925.. Serial No. 51,237., I

ToaZZ whom-2'73 may f Be it known that I, HowAnnK. KING, a

citizen of the United. States, r'esiding at Philadelphia, inthe county of Philadelphia,

State of Pennsylvania, have invented a new and useful Improvement in Brick Machines and Methods of Oper'atingfthe Same, of

which the following is a'spec'ificationz My invention relates to improvements 1n brick machines. The object "is to provide improvements'inthe bar cuttinglrmechanism,

1 torted planes, so that some of the bricks arecounteracted and so that all the cuts shall be in'parallelzplanesl,

:In machines of the type described in my Patent No. 1',178,980,dated Apr. 11, 1916, it"has been found that the bar of material 4 which is cut into separate bricks, has a tendencyto'expand toward 'its outer end,

especially when the baris composed of shale Orsimilar material. This tends to cause the cutting wires-to severjthe barf in disnot out in strictly parallel planes. have found that by 1 clamping the forward end of the bar as it, assumes its position, on the cutting platens, this .tendency to expand. is a true cutof all the bricks is assured. 2 "Referring to the drawings, which illustrate merely by way'of examplesuitable means for effecting my invention I Fig. ,1 is a fragmentary end elevation .o the reel frame, showing my improvement.

ing the cutting operation, that it tends to expand towardthe forwardend, which results in an irregular or distortedcut. To

prevent undesirable action plt vide the following. mechanism. 1

theU shaped frame 13 ;-the other "endofthis "frame being pivotally mounted in the bracket '14, .also bolted to housing 5. Integral with frame 13 is the arm 15, having therollerlfi on its outer end. On the frame 13,

is adjustably mou'nted the clamping-blade ably. secured to the angleiiron' 19 and the angle;iron.19; is adjustablyseoured to the frame 13;'by any suitable" means, such by bolts and slots, as shown. A lug 20,semired-[to an armor frame 13, is'adaptedto engage an abutment 21 on frame 11, to'limit the spring actuated movement of frame13.

Onthe standard 6 is se'oure'd-the-bracket 22,.uponwhioh is pivotally mounted as'at 23,'the cam 24. -The' bracket 22 is provided with fthe ilug 25, preferablyintegral therewith, for limiting the. gravity I actuated pivotalmo-Veinent of the cam 24. I

In operation: As above stated,j 1;hereel .17, a spring 18 connected between the piv- Yot ed frame 13- and the frame 11, normally holds theframe and clamping blade-l7 in elevated position above the topplane of the-bar 10. The clamping blade 17 isa'djusthousing :5. has a horizontal, reciprocating I movement; to theleftto receive-the b'ar 10, and to the right to move with theb'ar while the cutting wires 9-are passing through it."

'Fig. 2 shows the positions of theparts during the movement of the housing'to the right. and during'th'e cutting operation with n the clamping blade 17 in engagement with bar 10. As the housing 5 completes its movement to theright and after the cutting operation is completed, the roller 16 passes I over the end of lug 25, whereupon the spring 18 drawstheframe upwardlyandfl the blade 17 into the position shown in Fig.

3.1 As the housing5 now moves to, the left to receive a new length of bar 10, the roller passes under cam 24. hen roller 16 clears the lower left hand end by cam 24, the cam falls into position shown in Fig. 4, so that, upon the returnmovement of housing 5 to the right, the'roller' encounters the inclined face 24 of cam 24 which carries the roller up to the top substantially horizontal-face of the cam and consequently brings the blade 17 again into clamping position upon the bar 10. It will be noted that the top surface of cam 24 and lug 25 inclines slightly upwardly from the left hand end to the right hand end to insure efficient engagement of the clamp 17 with bar 10, during the cutting movement of the housing 5. It will also be noted that the axis 12 of frame 13 is below the top surface of bar 10, so that the engagement of camp 17 with bar 10 serves effectually to counteract any tendency to further relative movement between the bar 10 and the cutting platens and cutting wires.

It should also be noted that the extreme right hand end of bar 10, which extends beyond the last cutting wire 9, varies in dimension and is therefore discarded as waste or defective. As this end piece will sometimes approach the full or regulation thickness of the brick, it cannot always be readily recognized by the operatives, and hence there is a tendency for some of these defective end-pieces to slip through to the kiln and thus make trouble. By observing the mark upon this endpiece, made by the clamping plate 17, which always engages the bar near the extreme end, and therefore within the area of the end-piece, said defective end-piece becomes readily distinguished, so that the danger of overlooking any defective end-piece is thereby eliminated.

lVhat I claim is 1. The method of preventing distortion in the wire cutting of bars into bricks, which consists in clamping the end of the bar to its moving support during the cutting op eration.

2. The method of preventing distortion in the wire cutting of bars into bricks, which consists in atomatically clamping the end of the bar to its moving support during the cutting operation.

3. The method of distinguishing defective end-pieces of a bar which is cut into bricks, which consists in producing a visual mark upon the said end-piece before the cutting operation is completed.

..In combination with bar cutting mechanism for brick machines, a clamping device and means for actuating the clamping device to engage the bar near the extreme forward end thereof during the cutting operation.

5. In combination with bar cutting mechanism for brick machines a clamping device and means for actuating the clamping device to engage the bar near the extreme forward end thereof prior to and during the cutting operation.

6. In combination with bar cutting mechanism for brickmachines, a clamping device and automatic means for actuating the clamping device to engage the bar near the extreme forward end thereof during the cutting operation.

7. In combination with bar cutting mechanism for brick machines, a clamping device and means for actuating the clamp ing device to engage the bar near the extreme forward end thereof during the cutting operation, and means for releasing the clamping device from the part of the bar engaged thereby upon the completion of the cutting operation.

8. In combination with bar cutting mechanism for brick machines, comprising a rotatable wire reel and a reciprocating housing therefor, a clamping device mounted on the housing, and means mounted on a stationary part of the machine for cooperating with the clamping device to cause its engagement with the bar near the forward end thereof during the cutting operation.

9. In combination with bar cutting mechanism for brick machines, comprising a rotatable wire reel and a reciprocating housing therefor, a clamping device-mounted on the housing, means mounted on a stationary part of the machine forcooperating with the clamping device to cause its engagement with the bar near the forward end thereof during the. cutting operation, and means for moving the clamping device out of the path of travel of the bar after the cutting operation is completed.
