DEVICE FOR POLISHING CURVED SURFACES.

Specification of Letters Patent.

Patented A t-.11, 1911.

Application filed December 29, 1910. Serial-No. 599,971.

To all whom it may concern:

Be it-known that 1, JAMES R. RICHARDSON, a-citizeii of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have iiivente'd certain new and useful [in roveinents in Devices for-Polishing CUI'VQC Surfaces, of which the following is a specification,

reference being bad therein to the accompanying drawing.

This invention relates to a device for polishing curved surfaces, and more particularly to a device for polishing and grinding the rolls in rolling mills, whereby the rolls at any or all times can be readily and easily cleaned, smoothed or trued by grinding away all foreign matter, which frequently collects or adheres to the face or surface of the rolls.

The objects of my invention are to provide a device of the above type with means as will be hereinafter set forth for positively retaining an abrasive material in engagement with the rolls of a housing, and to provide means whereby the material can be removed and replaced without entailing the stoppage of the mill.

Other objects of the invention are to prothe present type of rolls and housin s, and

vwhich will not interfere with the coder or catcher or any workmen attending the rolls.

Further ob ects of the invention are to ,provide novel adjustable holders for an abrasive material or a lubricant, and'to obviate the expenseand labor incurred by employing an attendant for cleaning and ubrieating rolls.

Still further objects of the invention are to provide a polishing device that can 'be zulva ntageously used in connection with hot inilljrolls, and to accomplish the above results by a device that is sim le in construction, durable, easy to inst: l and operate, and highly ellicient for the purposes for which it is intended.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be presentlydescribed in detail and then claimed.

Reference will now be had to the drawing, wherein there is illustrated a preferred embodiment of the invention, but it is to be understood that the structural elements being 6 to the housingstl.

thereof are susceptible to such modifications as fall within the scope of the appended claims.

In the drawing:-I ig'ure 1 is a vertical sectional view of a set of rolls provided with polishing devices, Fig. 2 is a erspective view of a hand operated device, and Fig. 3 is a similar view of a treadle operated device.

In the acconipanyin drawing the refercnce numerals 1 and 2 denote, by the way of an example, two rolls arranged one above the other and supported by an ordinary type of housing 3 and a bed-plate '4, and in connection with each "roll I use a polishing or grinding device, the devices being identical in construction and applicable to either.

side of the rolls, it bcin preferable toadjust the device of the r01? 1 by hand and the device of the roll 2 by foot, but it is in this connection that I reserve the right to manually operate or use any other means for shifting the adjustable levers of the polishing and grindin devices. I

, As the devices are identical, I deem it only necessary to describe the device in connection with the upper roll 1. The fconfr'on't ing sides of the housings 3 are provided with oppositely disposed angle rails 5, these rails riveted or otherwise connected, as fat The inner ends the rails 5 are cut away, as at 7 and the lateral flanges bent upwardly, as at 8 and then outwardly, as at 9 to provide a stop or trap at the inner end of each rail.

Movably mounted upon the rails 5 and limited by the traps thereof are rollers or wheels 10 revoluhlymounted upon the ends of a longitudinal axle 11. Pivotally moanied upon the axle 11 adjacent to the rollers or wheels 10 are the hangers 12 of achannel-sha ed longitudinal box or holder-13 adaptm to hold one or more piecesl l'of abrasive lfliltelltll, flS emery, sandstone or the like. Graphite or other lubricant can be substituted for the abrasive material.

"The confronting sides of the housings 3 beneath the rails?) are provided with studpins 15, and pivotally inonntwliipon said pins are operating levers 16 having the forward ends thereof curved, as at 17 to engage the rear side'ot' the holder 13 and the forward ends thereof provided with handles ortreads 18. Each operating lever 16 has a depending tooth 11) adapted to engage a curved rack 20 having the ears thereof conneeted to the housings 3, as at 21, said racks holding the operating lovers in an adjusted position, with the abrasive material 14; of the holder either in or out of engagement with the roll 1.

From the foregoing it will be observed that I have employed an upper and lower )olisher for a set of rolls, andas each'polisher constitutes an independent unit, any number of polishers can be employed according to Where the roll is most worn or cut by sheet metal wearing against it, further that it is not necessary to true the rolls the whole of their length or only a portion thereof and further more than one set of rolls is ar 'anged in the housings. The juxtaipositioirof the lower polisher relatively to the bed-plate permits of. a treadle being more convenicntlynsed in connection with the operating levers thereof, while the 11 per polisher can be conveniently manipulated by hand. It is apparent that when either set of levers is elevated that the polishers can he swung out of engagement with illQ'lOllS and by having the operating mechanism in proximity to the housings, the

'operations of a workman at either side of operating levers pivotally supported by the I confronting sides of said housings and adapted to retain the abrasive material contained within said holders against the rolls to be polished.

2. In a device for polishing rolls, the combination with housings, of oppositely disposed ;ails secured to the confronting sides of said housings adjacent to the rolls to be olished, wheels movably mounted upon aid rails, hangers movably supported by said wheels, a holder carried by said hangers and adapted to contain an abrasive material to engage the rolls to be polished, operating levers pivotally supported by the confronting sides of said housings and adapted to retain the abrasive material contained within said holders against the rolls to be polished, and .n'ieans carried by the confronting sides of said housings and adapted to lock said operating levers in van adjusted position.

In a polisher for rolls, the combination with housings, of rails. carried by the confronting sides of said housings and having the inner ends thereof provided with traps, wheels movably mounted upon said rails and adapted to be limited in their movement by said traps, hangers movably supported by said wheels, a channel-shaped holder carried by'said hangers and adapted to contain an abrasive material to engage the rolls to be polished, ope 'ating levers pivotally connected to the confronting sides of said housings and having the forward ends thereof curved to engage the rear side of said housings, and means including racks adapted to retain said levers in an adjusted position. 4 j

4. In. a polishing device for rolls, the combination with housings, rails carried by the confronting sides of said housings and having the inner ends thereof shaped to provide traps, longitudinal axles, wheels revolubly mounted upon the ends of saidaxles and adapted to ride upon said. rails and be limited by said traps, hangers carried by each axle, a channel-shaped holder supported by saidhanger adjacent to each axle and adapted to contain an abrasive material to engage the rolls to be polished, and means carried by the confronting sides of said. housings and adapted to adjust said holders relatively to the rolls to be polished. In testimony whereof I afiix my signature in the presence of two witnesses.
