GILBERT B. LOWE, OF JAMESVILLE, NEW YORK.
IMPROVEMENT IN ELEVATORS.
Specication forming part of Letters Patent No. 117,789, dated August 8, 1871.
To all whom yit may concern:
Bc it known that I, GILBERT B. Lowe, of J amesville, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Elevators 5 and I do hereby declare that the followil'ig is a full, clear, and exact description thereof, which will enable others to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a sectional side view of iny improved elevator, and Fig. l2 is a front view ofthe lower part thereof. Fig. 3 shows a modification oi' a detail.
Similar letters of reference indicate like parts in the several iigures.
In the accompanying drawing, A is the casing, B is the drivin g-wheel, and b the lower or guidewheel. O is the chain-belt, D are the buckets, and E rollers or pulleys for supporting the chain and buckets. In place of the ordinary leather or ilexible belt I use a chain-belt, O, which is driven by a sprocket or rag-wheel, B. This chain O is made ot' links that are pivoted together, and the buckets l) riveted thereto at regular intervals. To guide the buckets and relieve the chai n from sag or friction a crossliead or axle, c, is fastened to the chain at each bucket, and its ends provided with rollers or wheels E E that travel ou ribs or guides F and f', the ascending rollers traveling` on the front guides F F, and the descending rollers on rear guides ff. The chain is made of malleable cast-iron links, so as to be strong and light. These links can be cast with tongues or projections H and bars h, as shown in Fig. 3, and fast ened together by bending the tongue around the bar, and in this manner dispense with the work of drilling for the pivots to fasten the links together. In constructing the sprocket-wheel B and lower wheel d they can be made with openwork peripheries, so that in elevating coarse material lumps cannot lodge between the chain and the part oi the wheel on which it treads. By these means the friction of the belt in the legs of the elevator is avoided, and the rapid wearing out of belts for elevating lime, sand, and other material, is obviated.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
In connection with the elevating-buckets I) D, the chain-belt C, drivin g-wheels B b, guide-rollers E E, and ribs or tracks F j', all constructed and operating substantially as and for the purpose described.
The above speciiication of my invention signed by me this 17 th day of April, 1871.
Vitnesses l GILBERT B. LOVE.
