METAL-SCALPING MACHINE AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 15, 1916..

Application filed December 8, 1915. Serial No. 65,700.

To all cvkom it may concern:

Be it known that I, EDWARD 0. Gross, a citizen of the United States, residing at Waterbury, county of New Haven, and

.The invention is applicable, however, to machines for handling other metal, and generally to machines for scraping, clearing or otherwise cutting the surface of metal sheets or bars.

The special object ofthe invention is to hold the metal sheet or bar firmly and in proper position during the scalping or other cutting operation, thus assuring uniform action on the metal and preventing all looseness or chattering of the plate or bar during scalping, and I secure this result by the use 'of feeding rolls arranged out of line longitudinally of the metal feed and so as to tend to bend the plate or. bar over the pressure roll which co-acts with the scalping roll dur ing scalping, and thus press the plate or bar against the pressure roll to hold it during scalping.

For a full understanding of the invention, a detailed description of a construction embodying the same in its preferred form as applied to a scalping machine for treating brass lates, will now be given in connection with the accompanying drawings forming apart of this specification, and the features forming the invention then specifi-y cally pointed out in the claims.

In the drawings-Figure 1 is a side elevationof the machine, with parts broken away to show the roll adjustment; Flg. 2 1s an end view looking to the right in Fig. 1,

and Fig. 3 is a diagrammatic vertical section, on an enlarged scale, illustrating the roll arrangement and metal feed.

Referring to the drawings, the scalping machine shown is adapted to scalp or overhaul successively the two sides of the metal plate as it passes through the machme, A, A being the respective scalping rolls, and

B, B the corresponding pressure rolls, and the pairs of feeding rolls on opposite sides of the scalping and pressure rolls, by which the metal sheet as is fed through the machine, are lettered C C, C C, C C In connection with these rolls, single feeding rolls D,

D are shown at the front and rear end of the roll train, the metal sheet w entering the train over roll D and leaving the train under roll D.

The scalping, pressure and feeding rolls may be mounted and driven in any suitable manner. As shown, the rolls are mounted n s de frames E on base frame F, and in vertically adjustable bearings 10, these bear 'ings belng shown as adjusted by screws 11 engaging the bearing blocks and operated by screw sleeves 12 actuated by bevel-gears 13 from adjusting shafts 14.

The arrangement of the rolls, in accordance with the present invention, will be clear from Figs. 1 and 3, which show that the pressure roll B is slightly above the straight line of feed between metal rolls C G and C C, so that the plate is bent slightly over the top of pressure roll B and thus held firmly in position during the action of the scalping roll A, and that pressure roll B is slightly below the strai ht line of feed between feeding rolls C C and. C C so that the plate is similarly held against roll B during the action 'of the scalpingroll A on the opposite side of the plate. From rolls G the plate passes under roll D which, as shown, preferably isset slightly below the roll C so as to tend to straighten out the plate as it leaves the roll train. The arrangement of the rolls is preferably such as not only to hold the plate firmly during scalping, but, with scalping rolls acting on opposite sides of the plate, to correct the slight bending of the plate and deliver it substantially straight, or the plate may be rolled straight after passing through the scalping machine.

It will be understood that the invention, considered broadly, is not limited to a machine having scalping rolls for acting on both sides of the metal during its passage through the machine, although such a construction is claimed specifically as a part of the invention. It will be understood, also, that the invention is not limited to the particularconstruction or arrangement of parts illustrated, but may be applied in many forms while retaining the invention defined by the claims.

What I claim is: 1. In a metal scalping machine or the 5 like, the combination with a scalping or cutting roll and its co-acting ressure roll, of feeding rolls on opposite si es of the scalping and pressure rolls; the pressure roll and feeding rolls being arranged out of line to 10 press the metal against the pressure roll dur- 1ng scalping.

2. In a metal scalping machine or the like, the combination with scalping or cutting rolls for acting successively on opposite sides of the metal and their co-acting pressure rolls, of a series of feeding rolls including rolls on opposite sides of each pair of soalping and pressure rolls arranged out of line with the pressure rolls to press the metal against the'successive pressure rolls during scalping.

In testimony whereof, I have hereunto set In hand.

y EDWARD o. eoss.
