WHEEL AND PULLEY.
SPECIFICATIN forming part of Letters Patent No.
283,397, dated, august e1, lese.
Application led March 14, 1883. (No model.)
used for belting for machinery and for other niechanicalpurposes, the object being to con` struct such pulleys and wheels of thin metal and in such a mannerthat they shall not only be light, but strong and serviceable; and my invention consists in certain features of construction, hereinafter described, and specifically set forth in the claiins.
Referring to the accompanyingdrawings,
i forming a part hereof, Figure lis a vertical section; Fig. 2 a side elevation, and Figs. 3 and 4: niodications of a wheel or pulley constructed in accordance with my invention,
Like letters refer to like parts in all the iigures.
The hub A consist-s of acasting suitably bored to fit a shaft. Upon the outer surface of the hub and cast integral therewith are two ribs or flanges, a., which extend completely around. These flanges have their outer face dressed to receive two disks, B, which are dished or concaved, and provided with circuinfcrential'langes b, turnedoutwardly. The outer face of the ribs or flanges upon the hub A are concaved to conform to the dish shape of the disks B. These disks may be secured to the hub by placing them in a suitable mold and casting the metal intended for said hub in contact with the central portion of said disks; or they may be secured to the ribs or flanges c by rivets or bolts b, passing transversely through said ribs a. The-disk B and clampingrings a upon the hub, and the inner ribs,
v which, in such a case, would be formed integral with the hub, may be sorew-threaded, and bolts inserted from the outside of the rings a through the saine intothe screw-threaded ribs.
B is a hoop of sheet metal having circumferent' anges B2, extending outwardly to conform to e flare or dish shape of the disks B. This hoop B is secured to the disks B by riv- The face plate or rim C of the pulley is secured to the outer faces of the anges b by shrinking on or by rivets,'as clearly shown,
with the end `of the riin the latter is well sup ported, and the edge of the pulley is niade to appear thicker. rlhe rim C may be flat, as shown in Fig. l, or crowning, as shown in Fig. 3, the flanges on the disks B being conformed thereto o n the left side of said figure, while on the right sidea beveled ring, Z22, having one edge thicker than the other, is used between the flange of the disk and the face plate or rim C.
If desired to produce a pulley having a face of wood laggings, or a cast-metal face, or any face thicker than those shown in Figs. l and 3, such face may be provided with an inwardlyproj ecting shoulder, C', adapted to t the flare and flanges of the disks B.
By the construction thus far described it will be seen that the interior hoop, B', greatly strengthens the structure of the wheel, as it acts as a tie-rod and brace between the disks B. Therefore it is apparent that various modiiications may be niade in the details of construction without departing from my invention. For example, instead of making the hoop B continuous, it may be made in detached sections having anges or angle-irons, said sections eXtending a quarter more or less) around the hub A, and braces made of bar-iron may be used for the saine purpose. In case the flanges are dispensed with upon the hoop or sections thereof, perforations may be made through the disks B to receive lugs or proj ections formed on the hoop or hoop -sections This construction would resist pressure exerted inwardly against or by the disks. To resist pressure exerted outwardly the lugs formed upon the hoop-sections may be turned against the outer surface of the disks, or headed or upset in the perforations therein. These disks may also be provided with hand-holes or other perforations to facilitate their construction, or for the purpose of lightening the disks, and as they are intended to be of light sheet-metal, they may also be strengthened by having flat rings or large washers b3, of a diameter not less -than the flanges c and b of the hub, soldered around their inner edge to resist the tension of the rivets. The outer periphery of the hub should also be turned true, so that the eye of the disk will lit closely thereon.
I am aware that pulleys have'been made and as the edge of the flanges extend iiush with a cast-metal hub, a sheet-metal rim, and disks of sheet metal having their outer edge iianged over the rim thereof, but their construction differs from mine. Having described my invention,what I -claim isy 1. In a wheeler pulley, the combination of a hub, disks secured to the same, and intermediate bracing or strengthening hoop, or its -described equivalent, and a rim or face, the whole being secured together, substantially as specied.
2. The hub A, provided with the ribs a, the disks B, the hoop or braces B, secured to and between the disks and the face G, substantially as specified.
3. In combination with the rim of a pulley, concaved disks, having circumferential iianges turned outwardly and extending iiush with the edge of said rim, whereby the edge of the pulley is increased in thickness and is supported, substantially as described.
6. 'A pulley constructed with a east hub,
wrought-metal disks, and wood rim, substanl tially as described. j
In testimony whereof I affix my signature vin presence of two witnesses.
