WILLIAM H. BAILEY, OF CANAL DOVER, OHIO.
SPRING-BALANCE FOR METAL ROUGHING AND FINISHING MILLS.
SPECIFICATION forming part of Letters Patent No. 770,950, dated September 27, 1904,
Application filed September 27, 1902. Serial No. 125,086. (N d l) To all whom it may concern:
Be it known that 1, WILLIAM H. BAILEY, a citizen of the United States, residing at Canal Dover, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Spring-Balances for Metal Roughing and Finishing Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to a spring-balance for metal roughing and finishing mills or means for automatically balancing and raising, also the steady and even lowering of the top roll of a mill when the screws are run up or down the desired distance, so as to leave the necessary space between the rolls as required, according to the thickness of the bars of metal to be inserted between said rolls, and although more especially intended or designed for service on metal roughing mills is also susceptible for use on various other mills or devices of a different character, but wherein the principles are similar.
The principal objects and advantages of this invention consist in producing a device that will take the place of and be an improvement over the old method of raising the upper or top roll of a metal mill when the screws are run up, as heretofore. It then being customary to employ the old style of lever-balance wherein a long lever and weights are used, said lever being placed in the pit under the rolls. This method is very objectionable, for the reason that there is considerable trouble caused by the weights falling off and being down in the pit are difficult to handle. Besides they need constant attention; but my spring-balance needs no attention, as it works automatically, is efiective in its results, simple in construction, can be readily and easily handled and repaired, and is inexpensive in cost of manufacture.
My invention, referring in general terms to its construction, consists of the bridge and wherever they occur throughout the several views, Figure 1 is a view in end elevation of a pair of rolls and the housing for same and having my spring-balance in operative position, so as to show the practical application of my invention. Fig. 2 is aside view ofmy spring-balance with the parts together ready to be placed in position between a pair-0f rolls. Fig. 3 is a perspective view in detail of the carrier. Fig. i is a perspective view in detail of the bridge. Fig. 5 is a perspective view in detail, partially broken away and in section, of one end of the bridge, so as to show the construction when the supports are formed integral and a part of the bridge, which may be done when desired; and Fig. 6 is a view in front elevation of a pair or set of rolls and the housings for same, partially broken away and in section through the window of the housing at one end and taken on the line y 3 of Fig. 1, showing my springbalance in operative position, so as to more fully illustrate the practical application of'my invention.
In describing my said invention and referring in detail to the different parts or mechanical elements of construction as shown throughout the various views of the drawings, and indicated by means of the letters of reference, as aforesaid, A refers to the carrier, preferably constructed out of cast-steel and provided with a bearing a, of brass or Babbit metal, which bears up against and upon which rests the neck of the upper or top roll when said carrier is in position, said carrier being further provided with lugs or projections Z), adapted to rest and move in suitably-formed recesses or grooves located in the inner face of the housings at each side of the windows, thus permitting of the carrier moving up and down as it forces said upper roll upward or permits of said upper roll moving steadily and evenly downward, according to the direction in which the screws B are run, by reason of the action of the springs or reacting members C, which are retained in place in an upright position by the small bearings (Z and e, projecting from carrier A and bridge vF, respectively. Bridge F is preferably constructed out of cast-steel (the same as carrier A) and acts as a support for the carrier, as is clearly shown in the drawings, particularly in Fig. 1, said bridge being in turn supported in a stationary position by lugs f, which may be placed or formed on the inside of the face of the housings, as shown in Fig. l, or said lugs may be separate from the housings and formed integral with the bridge and provided with openings or eyes 9, adapted to receive screws, as shown in Fig. 5, the under side or face of said bridge being slightly concaved, as at h, thus leaving a space, as at 2', between itand the neck of the lower roll, which permits of oil, grease, or other lubricant being applied to the neck of said roll when found necessary, said bridge being further provided with lugs Z, adapted to rest in the recess or groove in the housings.
If desired, both the carrier and bridge may be suitably provided with a suflicient number of perforations to allow of water passing through onto the neck of the rolls, thus cooling them.
It can be clearly understood and will be obvious from the foregoing description that my spring-balance is of course intended and designed to be inserted in the window of each housing at both ends of the pair of rolls. It will act automatically and by reason of the springs or reacting members will permit of the upper roll working steady, even, and uniform, will do away with all labor in raising the upper roll, and being above ground and in plain view the condition of the device can be seen at all times, and, furthermore, my spring-balance can be manufactured and any worn parts readily replaced at a very small cost.
I wish it to be here understood that I reserve the right under the well-established principles of patent law to make any minor changes and alterations in the arrangement and construction of the several parts of my device as may from time to time suggest themselves so long as within the scope and not departing from the spirit and principles of the invention.
Having now described my spring-balance for metal roughing and finishing mills, I will proceed to point out what is new and my invention. Therefore I/Vhat I claim is 1. In a rolling-mill, and in combination with the upper and lower rolls, of a carrier for the upper roll having a central bearing for said roll, end lugs fitted to slide in the frame of the mill, and projections upon the under face of said carrier near the lugs, and a bridge having lugs fitted to slide in the frame of the mill, projections on the upper face of the bridge in line with the lugs on the carrier, and a central bearing for the lower roll, and springs intermediate the carrier and bridge said springs being seated upon the projections of the carrier and bridge.
2. In a rolling-mill, the combination of the upper and lower rolls, a carrier for the upper roll having a central bearing fitted therein, end lugs mounted to slide in the frame of the mill, projections upon the lower face of the carrier near the lugs, a bridge having a central bearing for the lower roll, lugs to slide in the frame, projections upon its upper face in line with the projections on the carrier, springs interposed between the carrier and bridge and seated upon the projections of the carrier and bridge, lugs at the ends of the bridge, and a screw for adjusting the rolls.
In testimony whereof I have affixed my signature in presence of two witnesses.
WILLIAM H. BAILEY.
