Description

Patented Jan. 28, 1930 N ED STATES; PATENT OFFICE WALTER C. ELY, OF TERRE HAUTE, TNDIANA, ASSIGNOR TO AMERICAN CHAIN 6 COMPANY, INC., 'A CORPORATION OFNEW YORK BLOOM, SQUEEZER Application filed January 7, 1927; Serial No. 159,537.

This invention relates to bloom 'squeezers and more particularly to thetype of squeezer used for squeezing or working the bloom from a puddling furnace to vremove the slag and form an integral mass preparatory to rolling.

As is well known in puddling furnace practice, it is necessary to squeeze or compress the ball or bloom taken from the furne cc to force out some of the slag and compress the iron into an integral mass. It is sometimes desirable to have the bed of the squeezer adjustable in order that the size of the finished product may be varied, or, as is quite often the case, to compensate for wear in the bed and c face of the cylinder.

The object of my invention is to provide a means that will vary the relative distance between the bed and the roller in order to attain the ends set forth above.

A clear conception of the construction and further objects of the invention may be had from the following specification in conjunction with the accompanying drawings in which n Fig. 1 is a plan view of the invention;

Fig. 2 is a cross section through 22 of Fig. 1; and

Fig. 3 is a detailed view through 3-3 of Fig. 2.

The now preferred form of the invention consists of a frame 1 shaped as shown carrying a bed portion comprising a series of corrugated segments such as 2 and 3. Mounted on frame 1 in a bearing 41 and held in position by any suitable means such as journal 5 is a shaft 6 carrying a roller 7 having a number of corrugations 'or teeth in its face. A gear 9 mounted on the shaft 6 co-operates with a driving gear 10 which is operated by any suitable driving means suchas a motor.

A table 11 composed of three bars formed as shown is mountedin a recess in the frame 1 and is moved in and out of said recess by a cross bar 12 pivoted at 20 which is operated by a lever 13. This table is used for easing the bloom into the squeezer as a precaution against jamming. As is well known in the art, if the bloom were allowed to fall between the roller and bed it would become jammed, thereby stopping the machine.

The bed plates 2 and 3 are recessed as shown in Fig. 2 to accommodate cross bars such as 14.

There is an adjusting means for bars ,ll comprising a wedge 16 and a bolt 17 for varying the relation between the bed plates 2 and 3, and roller 7 This adjustment is effected by the movement of wedge 16in and out of a. slot 15 provided in frame -1. The slot 15 is of sufficient length to accommodate bar 14 and the wedge 16 when it is in its extended position. The movement of wedge 16 into slot 15 causes the cross bar 14 to be moved forward carrying the bed plates 2 and 3 into closer relation with roller 6. A nut 18 is provided to effect this-movement and a lock nut 19 is provided to-keep the wedge from any inward :or outward motion. The arm of Wedge 16 carry.- ing the bolt is provided with a slotted hole to allow for any lateral movement when the wedge is moved into and out of engagement with the cross bar 14.

.InFig. 3 such awedgeis shown in detail, and I prefer to provide a similar wedge device for each of the bars 14 at the joints be tween the adjacent segments which together form a continuous working device. a

It is apparent that the adjusting mean described above is a simple and effective method for varying the distance betweenthe' roller and bed plates of asqueezer.

1. In a squeezer of the type. described, a roller having co-axially extended corrugations on its face, a bed plate comprising a plurality of segments having corrugations on the face thereof, andcombining to fonn=, a, continuous working device, said bed plate being set at a varying distance from the roller and an adjusting means for varying the rel-f ativedistance between said bed plate seg-v ments respectively and said roller.

2. In a. squeezer of the type described, a frame, a roller having corrugations inits, face mounted on said frame, a bed plate c0mprising a plurality of segments having corrugations on the face thereof, said bed plate being set at a varying distance from the I roller, cross bars adapted to be mounted in slots in saidframe and hold saidsegnients,

and awedge shaped adjusting means for 00- 1e operating between the frame and said cross bar for varying the relative distance between said bed plates and said roller.

3. In a squeezer of the type described, a frame, a roller having corrugations in its face mounted onsaid frame, a bed plate comprising a plurality of segn'ients having corrugations on the face thereof, said bed plate being set at avarying distance from the roller, cross bars adapted to be mounted 'in slots in said frame, and an L-shaped adjust ing means having a slotted hole in one of its arms for cooperation with abolt on said frame, said bolt being used to force the wedge portion of said adjusting means between said frame and said cross bar to vary the relative distance between said roller am said bed plate.

4. In a squeezcr of the type described, a frame, a roller having corrugations in its face mounted on said frame, a bed plate comprising a plurality of segments having corrugations on the face thereof, said bed plate being set at a varying distance from the roller, cross bars adapted to be mounted in slots in said frame, and an L-shaped means adding a wedge as one arm and a slotted hole in the other arm for cooperation with the bolt on said frame, said bolt being used to force the wedge portion of said adjusting means between said frame and said cross bar to vary the relative distance between said roller and said bed plate.

'5. In a squeezer of the type described, a frame, a roller having corrugations in its face mounted on said frame, a bed plate comprising a plurality of segments having corrugations on the face thereof, said bed plate being set at a varying distance from the roller, cross bars adapted to be mounted in slots in said frame, and an L-shaped adjusting means having a slotted hole in one of its arms for cooperation with a bolt on said frame, said bolt having a nut above said arm and a second nut below said arm to securely hold said wedge from any lateral movement with respect to the cross arms.

6. In a squeezer of the type described, a roller having co-axially extended corrugations on its face, a bed plate comprising a plurality of segments having similarly disposed corrugations on the face thereof, and combining to form a continuous working de vice, said segments being adapted to be set at varying distances from the roller, and adjusting means in the form of wedges for vary ing the relative distances between said bed plate segments respectively and said roller.

7. In a squeezer of the type described, a frame, a corrugated roller and a bed plate supported respectively by said frame and a table supported by said frame at the region of entry of a bloom between said roller and bed-plate, said table being extended through the bed-plate below the initial biting point and adapted to receive the bloom and being movable to ease the bloom gradually between the roller and bed, thereby to avoid amming of said bloom.

8. In a squeezer of the type described, a frame, a. corrugated roller and a bed plate supported respectively by said frame and a table supported by said frame at the region of entry of a bloom between said roller and bed-plate, said table being extended through the bed-plate below the initial biting point and adapted to receive the bloom and being movable to ease the bloom gradually between the roller and bed, thereby to avoid jamming of said bloom, said table comprising a plurality of separated bars.

In testimony whereof I have signed this specification.

\VALTER C. ELY.
