Description

MOTOR MOUNTING Filed April 7, 1933' flWENTOR. JW/Wl'chell Patented July 2, 1935 PATENT OFFICE- 2,006,960 MOTOR MOUNTING James Willis Mitchell, Kenmore, N. Y., assignor to Du Pont Rayon Company, New York, N. Y., a corporation of Delaware Application April 7, 1933, Serial No. 664,897-
3 Claims.
1. This invention relates to a motor mounting. The invention has particular use in the mounting of the spinning bucket motors used in the manufacture of artificial thread by the 5 viscose process and will be described in connection with that manufacturing process, but it is to be understood that that particular description does not limit the invention.
2. In the manufacture of rayon by the socalled bucket process a spinning bucket is mounted on a vertically arranged electric motor. The motor, in turn, is mounted on a support and, in one form of mounting heretofore used, a rubber washer has been placed between the motor and the mounting to absorb vibration. That type of washer has proved unsatisfactory because it does not absorb enough vibration from a motor carrying an unbalanced load, because it is insufliciently resistant to the action of the oils and acids with which it comes in contact during use, and because it does not maintain its position, requiring frequent adjustment.
3. It is an object of this invention to provide an improved mounting for a motor. Other objects of the invention will be in part apparent and in part set forth hereinafter.
4. The objects of the invention are accomplished, generally speaking, by the use of a cantilever type bracket of rigid yet resilient material, providing a minimum point of support, centrally located under the motor, and a clearance between the motor and the body of the "bracket.
5. In the drawing Figure 1 is an elevational view of a motor with the bracket of my invention in cross section. Figure 2 is a plan view of one form of my mounting bracket. In Figure 3 is shown a modified form of mounting bracket useful with a rigid material of sufficient elasticity to make radial incisions in the edge unnecessary. Figure 4 illustrates a modification of the invention in which four separate arms serve to support the motor. Figure 5 is a view, partly in cross section, of another form. of mounting bracket. Figure 6 illustrates the fact that the mounting bracket can be used either in the uprigh position shown in Figure 1 or in the reverse position shown in Figure 6.
6. In the figures of the drawing I is a support, such as a wooden or metal frame upon which the motors of a spinning machine are mounted; 2 is a bucket motor; 3 is a stud projecting from the bottom of the motor casing through a hole in support I; l is a nut screw threaded on stud 3 to hold the motor firmly on the support; 50 is a motor-supporting bracket made according to the cantilever principle of my invention. In this form of the invention 5| is a plate of metal, of Bakelite, hard rubber, or of some other relatively rigid but resilient material; 52 is a hole provided in the center of the plate; 53 is an annular flange near the center of the plate and preferably about the hole 52; 54 is an annular flange toward, and preferably at, the rim of the 10 plate; 55 are incisions, preferably approximately radial, extending from the edge of the plate; 56 is a hole in the plate to receive a stud on the motor or on the support to prevent rotation of the bracket with respect thereto.
7. In operation my device functions as follows: The mounting will be assembled by passing the stud of the motor through the hole in the center of the plate and through the'hole provided in the support I and fastening it in place by the 20 nut 4. When the motor vibrates the vibrations will be absorbed by the cantilever action of the bracket which can be considered in the form of the invention specifically described in the preceding paragraph as composed of a number of 25 radial arms mounted cantileverwise at one end and bearing the motor at their other ends. The incisions in the edge of the plate give consider-. able resilience to materials, such as iron or steel, which in a solid form would be comparatively unyielding.
8. Other modifications of the invention will occur to engineers and to persons skilled in the art. For instance, the number of slots and the thickness of the mounting may be varied to accommodate the flexibility ofthe support to motors of difierent weights, or to loads of different magnitudes. The form of the invention shown in Figures 5 and 6 is illustrative of the fact that flanges 53 and 54 are not essential to the operation of the device. In the form of the invention shown in Figure 1, for example, the flanges could be on the support I and the motor 2, a, simple disk mounted between the said flanges accomplishing the objects of the invention. All such modifications fall within the scope of my invention.
9. An advantage of my invention is that the mounting permits the motor to flex in any direction with a freedom which satisfies the requirements of motors of practically all types and designs. Another advantage of the invention is that the mounting absorbs vibrations better than previous mountings. Another advantage is that the mounting is always centered and never needs adjustment. Another advantage of the mounting is that it can be made of a material which is not attacked by the oils and acids with which it comes in contact. Other advantages of the invention will be. apparent to persons skilled in the art.
10. As many apparently widely difierent embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that I do not limit myself to the specific embodiments thereof except as defined in the appended claims.
I claim:
1. In a resilient mounting a support, a disklike plate of relatively rigid material, radial incisions extending inwardly from the edge thereof to provide a degree of resilience in the plate, means toward the center of the plate to elevate the plate above the center of the support, and
means at the rim of the plate to support an object above the body of the plate.
2. Ina resilient mounting a support, a disklike plate of relatively rigid material having an inner and. an outer edge, incisions extending radially from an edge thereof to provide a degree of resilience in the plate, means toward an edge of the plate to elevate the plate above the support, and means toward the other edge of the plate to support an object above the body of the plate.
3. In a resilient mounting for a motor, a support, a member mounted on said support and comprising a disk-like plate of relatively rigid material having an inner and an outer edge, said member being provided with a spacing flange at the outer edge of said plate and being provided with incisions extending inwardly from the periphery of said member whereby to impart resiliency.
