HENRY AIKEN, OF HOMESTEAD, ASSIGNOR OF ONE-HALF TO DAVID I3. OLIVER, OF PITTSBURG, PENNSYLVANIA.

MILL APPLIANCE.

e ECIFICATION forming part of Letters Patent No. 415,663, dated November 19, 1889.

Application filed January 4, 1889.

To all whom it may concern:

Be it known that I, HENRY AIKEN, a citizen of the United States, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Mill Appliances, of which improvement the following is a specification.

In rolling-mill practice it is customary to weigh the articles operated on at various stages of their manufacture and also at the end of the finishing operation. This practice necessitates the employment of a large number of laborers to transfer the articles to and from the scales, especially when the articles to be weighed-such as slabs and plates-are large and cumbersome.

- The object of the invention described herein is to provide suitable movable supportssuch as casters, rollers, or any suitable form of roller-bearings-whereby the slabs, plates, &c., may be easily rolled along from one mechanism to another of the plant, in combination with scales arranged in such relation to the roller-bearings that the articles may be transferred to the platform of the scales by a movement of either the scales or roller-bearings.

In general terms the invention consists in the construction and combination of devices or elements, all as more fully hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a portion of a rolling-mill plant having my invention embodied therein in one form. of its application, the roller-bearin gs being represented by casters. Fig. 2 is a sectional view on the line 00 0c, the scales and its supporting mechanism being shown in elevation. Fig. 3 is a similar view on the line y y, Fig. 1. Fig. 4 is a plan view of a portion of a rolling-mill plant wherein are employed rollers having a greateror less length of bearing-face and fixed, as distinguished from .pivoted or swivel bearings.

1 In the practice of my invention I provide suitable roller-bearings 1, here shown as of caster construction, arranged on the floorplates 2 of the mill. in such relation to the various mechanisms A B, 850., forming a part of Serial No. 295,434. (No model.)

the plant that the slabs, plates, or other articles may be easily moved from one mechanism to another. The casters when employed are inverted, the end of the stem being inserted in the floor of the mill, as described in Letters Patent No. 393,051, dated November 20, 1888.

The mechanisms A B, &c., may be shears, a train of rolls, a hammer, or other mechanism employed in rolling-mill practice.

At such places as it may be desirable to arrange the scales a pit 3 is formed below the level of the mill-floor, and in this pit is arranged a hydraulic or other suitable lift or elevator 4, adapted to raise the platform or supporting part of the scales 5 above the level of the upper surfaces of the roller-bearings an amount sufficient to transfer the entire weight of the slabs or plates from the rollerbearings to the platform of the scales and to lower the platform or supporting part of the scales below said roller-bearings, so as to permit the slabs or plates to be moved away from the scales.

Any suitable constructionor form of scales may be employed, and they may be arranged singly or in pairs, as shown in Fig. 1, atany desired point in the plant; and while preferring to employ casters-i. e., rollers having the bearings movable horizontally as increasing the range of adjustment or movement of the plate or other article being operated on I do not limit myself to such construction of rotating bearing, but employ rollers such as shown in Fig. 4 or any other suitable form of rotating bearing, especially where, as is sometimes the case, the movement of slabs, &c., is always in one direct-ion.

It will be readily understood that various changes may be made in my invention without any substantial departure therefrom as, for example, the scales may be arranged below the level of the rollers or casters and the floor-plates adjacent to the scales may be arranged in a suitable lift or elevator, whereby said floor-plates, with their rollers or casters carrying the slabs or plates to be weighed, can be lowered until the slabs or plates rest upon the platform of the scales and then raised to normal position.

In order to protect the scale-beam and its l below the upper edges of the roller-bearings,

support from in j ury,-I provide bars (5, attached to the platform of the scales and extending over the scale-beam, as shown in Fig. 3, and in order to steady the scales while being raised and lowered I provide guide-rods 7, attached to the scales and extending down through suitable openings in the floor-plates.

I claim herein as my invention- In a mill plant, the combination of a series of roller-bearin gs and scales having their platform or supporting portion norm ally arranged the roller-bearings or scales being vertically movable, so as to transfer the article to be weighed from the roller-bearings to the platform of the scales, and vice versa, substantially as set forth.

In testimony whereof I have hereunto set my hand.

HENRY AIKEN.
