MEANS FOR ATTACHING eEARs o SHAFTS.
'ratenteu July 24, 1906.
Application filed September 16, 1905. Serial No. 278,300.
To all whom it may concern.-
Be it known that I, HERMANN A. KNOE- NER, a citizen of the United States of America, and a resident of'East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Imgrovements in Means for Attaching Gears to hafts, of which the following is a specification.
' The object of the invention is to provide a means for attaching ears to shafts by which the car will be fi rmly held without being force eccentric to the shaft .or distorted by the attaching means and which will admit of any removal of the gear without any unusual apparatus. i
A further object is to provide means which does not involve the tapering of the shaft and which leaves the shaft of cylindrical form and standard dimensions for the. substitution of pulleys of standard bores.
These means have been devised with especial reference to their applicability in connection with'armature shafts of electric motors.
In the accompanying sheet of drawings,
, which form a part of this application, Figure is provided. This key has a 1 shows in erspective the end of a shaft and a gear hel thereon by my improved means of attachment. Fig. 2 shows in perspective a key with a head on each end, which may be substituted for the key shown in Fi 1.
A gear G is bored so that it may e forced on a shaft S"with a comparatively moderate pressure-snug enough to prevent shake or appreciable play between the gear and shaft, but not so tight asto present any unusual difliculty in assembly or removal. With an easy fit of this character I'- have found that the employment of a set-screw or a key fitting tightly at its top and bottom to prevent either it or the gear from becoming displaced will throw the gear sufficiently eccentric to cause uneven runnin and noise. Therefore a key K fitting in a eyway in the shaftand fitting in a corresponding keyway inthe gear, but not fitting tightly at its tog1 and-bottom, ead h at one adjoining the gear to prevent the ear from workingfndwise of the shaft towar the head. The ey is as 101; as the combined width of the gear, inclu its hub and a collar 0. The collar lies next to the gear on the opposite side of the gear to the head on the key and prevents the gear from working endwise of the shaft toward this side. A setscrew 8 through the collar clamps the key against the bottom of the keyway in the shaft, thereby securely holding both the collar and key against movement along the shaft; The set-screw may be of any desired style; but what is known as a hollow setscrew, which has a socket-head, is desirable, since it has no projecting parts, which are a source of danger when on rapidly-moving machinery.
The key may have a head also on the end outside the collar at h, as indicated in the modification, the object being to prevent improper assembling. In the form having a ead at one end only of the key in assembling the key is first put in place either in the keyway in the ear with the head next to the ear or in the head away from the end, and the gear and collar are then slipped on the shaft. If a ke which has a head at each end is employe the gear and collar are first placed together with their keyways in alinement, then the key is set in the alined keyways, and, lastly, the combination is slipped over the end of the shaft.
What'I claim as new, and desire to secure by Letters Patent of the United States, is-
The. combination of a cylindrical shaft pro-' vided with a keyway, a gear bored to a moderately-snug fit for the shaft and also provided with a keyway, a collar formed with a ke ay and adjoining the gear, a key provi ed with a head ad oining the ear on the t ough the gear and 'collar and loosely fitting at its top and bottom m the gear and shaft, and a set-screw ta ped through the collar and serving to bind t e key against the bottom of the ke ay in the s aft beneath the set-screw and thereby secure the collar and key against displacement, substantially as described.
