UNITED STATES 1,543,706 PATENT OFFICE.
GEOEGE H. GABJCELON, OF SWISSVALE, PENNSYLVANIA, ASSIGNOR TO WESTING- HOUSE ELECTRIC MANUFACTURING COMIANY, A CORPORATION OF PENNSYL- VANIA.
RESILIENT DRIVE WHEEL. 2
To all whom it may concern:
Be it known that I, Gnonoa H. GAnonnoN, a citizen of the United States, and a resident of Swissvale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Resilient Drive Wheels, of which the following is a specification. I
My invention relates to resilient drive wheels for friction-drive, power-operated devices, and it has for its object to provide a novel device of the character indicated which shall 'be simple and inex nsive to manufacture, and strong and urable in construction.
In the accompanying drawings, Fig. 1 is a view, partially in section and partially in elevation, of a portion of a sewing machine upon which is mounted an electric motor provided with a drive wheel constructed in accordance with my invention; Fig. 2 is an end view of thedrive wheel and a portion of the hand wheel shown in Fig. 1; Fig. 3 is a sectional view of a modification of my invention; and Fig. 4 is an end elevational view thereof.
Heretofore, it has been customary, in devices employing friction drive, with power provided by small motors as, for example,
80 in sewing machines to construct the drive wheel in such manner that the entire motor must be resiliently mounted in order to maintain engagement between the drive wheel and the member which it engages.
By my invention, I provide a device wherein the motor may be rigidly mounted and the drive wheel be held in resilient engagement with the member it is driving by means of a spring member upon which the drive wheel is mounted. This spring member serves to hold the drive wheel in engagement with the member it is driving in spite of any irregularities in the engaging surface of either of these members.
Referring more particularly to the drawings, I have shown a portion 1 of a sewing machine provided with a hand wheel 2 and.
a head 3 upon which a motor 4 is rigidly mounted. The motor 4 is rovided with a shaft 5, upon one end of w ich is mounted a helical spring member 6 which, in turn,
supports a drive wheel 7, preferably moulded thereon. The shaft 5 is provided with a reduced gfiil'ltion 8 which extends longitudinally wit the spring memberfi but is spaced therefrom and from the drive entire length of the spring. The spring is preferably so wound as to tighten its hold upon the shaft when the drive wheel lags behind it on account of the load it is driving. From the foregoing description, it will be understood by those skilled in the art that, with a resilient drive wheel of this character, the resilient motor mounting may be avoided, thus enabling the designer to build a much more stable and rigid structure.
WhileI have shown only two forms of my invention, it Will be obvious to those skilled in the art that it is not so limited but is susceptible of various minor changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon.
as are imposed by the prior art or are specifically set forth in the appended claims.
I claim as my invention:
1. A power-transmission device comprising a driving shaft having one end of reduced diameter, a helical spring mounted on the larger portion of said shaft and surrounding, but spaced from, said reduced portion, and a drive wheel mounted upon the opposite end of said spring member.
2. A power-transmission device comprising a driving shaft, a spring member mounted thereon at one end and a drive wheel moulded on the opposite end of said spring member.
3. A power-transmission device comprising a shaft, a helical spring one end of which is mounted on the said shaft, a drive wheel moulded on the other end of said spring, and a portion of said shaft of reduced diameter extending longitudinally within said spring but spaced therefrom.
4. In combination, a sewing machine comprising a head and a hand wheel, a
5. A power transmission device comprising a driving member and a driven member, said driven member being resilient-1y mounted on said driving member for movement in all directions and so spaced therefrom as to.
have a limited transverse movement with respect to the axis of rotation of said' driving member.
6. 2:; power transmission device compris a driving member and a driven member. said driving member having a reduced end portion, and said driven member being resilientl mounted on said driving member for movement in all directions and so spaced from the reduced end of said driving member as to have a limited transverse movement with respect to the axis of rotation of said driving member.
'7. In combination, a sewing machine having a hand wheel mounted thereon, a motor rigidly mounted on said head and provided with a rotatable shaft, a driving wheel disposed in engagement with said hand wheel and mounted upon said shaft, said drive ment in a direction transverse to the axis of rotation of said shaft.
8. In comliiination, a sewing machine having, a hand wheel mounted thereon, a motor rigidly mounted on said head and provided with a rotatable shaft, a driving wheel disposed in engagement with said hand wheel and mounted upon said shaft, said drive wheel being mounted for movement in a direction transverse to the axis of rotation of said shaft.
9. The combination with a sewing machine comprising a head and a hand wheel, of a rigidly mounted motor having a shaft and resiliently mounted means for engaging said hand wheel and said shaft, through which the power of the motor is transmitted to said hand wheel.
In testimony whereof, I have hereunto subscribed my name this 24th day of Dec, 1918.
GEORGE H. GARCELON.
