MUSCATIIIE, IOWA, A CORPORATION OF IOWA.
PBOClin-E 3F MAKING STEEL PULLEYS.
1 Application filed July 30, 1915.
To all whom it may concern:
Be it known that I. NICHOLAS Bauer, a citizen of the United States,-residing at Mus catine, in the county of Musca tine and State of Iowa, have invented certain new anduseful Improwments in Processes of liiaking Steel Pulleys; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the ac companying drawings, which form part or.
this specification.
This invent-ion relates to sheet metal pulkeys and the like, and has particular refer ence' to the manufacture of split pulleys out of sheet metal; and its object is to enable such pulleys to be substantially made of light sheet metal as compared with what it has heretofore been necessary to use for pulleys of a given size and strength.
he present invention resides in the novel process of making sheet metal pulleys, wh ch pRocess consists essentiall in first forming the several members of the pulley, (such the hub, spokes and rim members of the pulley) out of separate pieces of sheet metal; second assembling the members, together to 'form .a pulley or split-pulley section and rigidly connecting the members, preferably by electric welds, so as to hold them in proper relative position and close together; and third dipping such pulley 0r split-pulley section as a whole, into a bath of molten metal or applying molten metal thereto in such manner'and quantity as will fill all the crevices between such members at the points adjacent the connections or welds uniting ,same, and sweat or solder the connected width, and also have all 'face view members together.
Pulleys made in accordance with this invention have substantially all of the advantages of lightness possessed by the best wooden split pulleys of equal diameter and the advantages of strength possessed by the best metal pulleys of equal diameter and width heretofore made. r
To impart a clear understanding of the present invention, I will describe the same as used in making split sheet metal pulleys, and the accompanying drawings illustrate a practical pulley manufactured in accordance with the present invention.
In sa d drawings: Figure 1 represents a of a complete split pulley; Fig' 2 is asect onal View thereof; Fig. 3 is an en- Speeification of Letters Patent.

larged inner face view of one section; Fig. is an enlarged sectional YlQW indicating how the stamped sheet metal members of the pulley are assembled and connected by electric welds; and Fig. 5 is a siinilar riew showing the process of construction completed.
Preferably the pulley is split, and formed of similar opposite sections. The opposite sections of the pulley are constructed alike, and may be united together around a shaft by suitable clamps, not shown. in the well known manner. Each section com prises a rim portion 1, having beads l on its sides, each bead having an internal enil flange l which lies against the inner face of the rim 1. Each rim portion stiftened by a central internal U shaped metal reinforce 2, to which are connected the outer ends of tubular sheet metal spokes 3, and the inner ends of said spokes are connected to a hub formed ol similar opposite sheet metal memsplit pulley bcrs Each rim section of the pulley is provided with sheet metal end plates 7. Each rim member 1, reinforce 2, spoke 3, hub n'icmbcr 5 and plate 7 is preferably stamped or pressed out of sheet metal. All the par ire orcterabl shaped as illustrated in the drau lugs, but in ay if desired.
In carrying outmy invention the members are assembled in proper relatireposition and permanentl) united by suitable means. I prefer to unite the members by electric welding. spot welds being indicated at w in Figs. l. and 5 ol the drawings. Where the members are united there will be some slight crevices or spaces left between the opposed portions of the united parts. as indicated at a in Fig. 4. But alter the membcrshave been assembled and united as described the pillley or illey section, as a unit is dipped into a bath of molten metal, preferably.composed of tin and lead or other metals, which molten metal flows all the crevices'beinto and fills tween the adjacent members, as indicated at c in 5, and also adheres to and solders or combines the ()pPOSLiLl surfaces of the connected members. and the exterior surfaces of the members will also be coated with such metal as indicated by the heavy lines C in ig. i
in practically using my process I preferably stampor press the various pulley members out of pickledsheet metal, that is metal be of other forms v.
preferably members of the sections to approximately the same temperature as the molten bath, which will cause the molten metal to coat the surfaces of the pulley and fill all the slight crevices between the connected parts thereof; I have found that these crevices will be filled because the molten metal or solder has a tendency to flow over'and cover all the metal surface with which it comes incontact, and over all exposed surfaces. 'Such dipping in molten solder or tin insures coating of all the exterior surfaces of the pulley and the filling up of all the crevices between the members thereof, so that the members become rigidly united and bonded or soldercd together, and the pulley becomes practically as unitary and homogeneous as if made in one piece.
Light metal pulleys which can take the place oi. wooden pulleys and be as easily handled have been greatly desired, and I I require less power have succeeded in making such a pulley by the described process the metal or solder forming an absolutely permanent conncction between the members. Light pulleys, to operate, but they must be able to withstand the working strains and in order to insure this I dip the pulleys in molten solder or tin not merely to protect I the metal from oxidization, but principally to till all the crevices or joints between the spot welds and firmly and-permanently unite the members; and this filling of all crevices by the metal prevents weakening of the welds or other fastenings.
As stated, after the pulley sections are as sembled they are preferably dipped in molten 'tin, or other suitable metal or composition of notal, which fills the crevices at the bends and joints and renders the surface of the pulleysmooth and practically solders the parts together and protects the parts against rust, and any slight crevices between opposed unwelded portions will be filled by the molten metal. in the soldering process, thus producing close joints and preventing looseness of parts. I have found by actual test that this dipping in metal increases the strength of the pulley about thirty per cent. Such pulleys are especially useful where exposed to dampness or to action of gases and solidly solder the parts which would be detrimental to: ordinarypulleys, sieet metal pulleys constructed in accordanc with my processar eqllijglent in strength to an integral metal pulley, and
can be made as light as a wooden pulley of the same size. The pulleys may be even lighter than wooden pulleys for in actual practice a twenty-four inch pulley four inch face made in accordance with my invention will weigh about sixteen pounds, whereas a wooden pulley of the same size would weigh about thirty pounds. By this process of manufacture I am'able to make pulleys out of much thinner metal than would otherwise be practical. If the samepulley was made without the step of dipping, soldering .o'i tinning, the members thereof-because of their lightness-would in use vibrate between the welds and in a short time cause the welds to crystallize and the pulley would go to pieces; but by dipping or sweating the pulleys in hot metal' as described the fluid metal fills all the crevices 0r cracks inthe joints and between the welds and practically amalgamates the several pieces and binds them solidly together as one piece and elimi'- nates vibration and consequently prevents weakening of the welds. The soldering or tinning is not merely intended to prevent rust or to enhance the appearance of the jpulley, but primarily to consolidate the pieces by filling all the loose joints or crevices with metal which becomes practically an integral part of the metal of the pulley and renders same practically homogeneous, stiff and strong. Y
In the specification and claim the expression dipping the molten metal is intended to cover dipping the pulley sections in'mol-' ten tin or other suitable metal or composition of metals, or so applying such hot metal to the parts as wili effectively close the joints and crevices between the connected pieces and firmly bond them together thus making the parts practically homogeneous and capable of withstanding great strain Without injury and contributing most materially to the durability and serviceability of the pulley. \Vhat I claim is: i Theherein described process of making sheetmetal pulleys consisting in separately forming the several members thereoi out of sheet metal; then assembling and rigidly connecting such members by "electric welds; then dipping the whole in molten metal to close all the crevices between the united parts of the members and around the welds together, substantially as described. r
In testimony that I as my own, I aflix my signature.
NICHOLAS Bauer.
