- SPRING SUPPORT FOR MOTORS Filed Dec. 20, 1928 warne d Patented June 9, 1931 PATENT OFF-ICE ARTHUR J. REED, OF PHILADELPHIA, PENNSYLVANIA SPRING SUPPORT FOR MOTORS Application filed December 20, 1928. Serial No. 327,453.

My invention relates to supporting devices for motors and has for its object to provide a support by means of which the vibra- 'tions incident to the operation of the motor are largely taken up in the support without being communicated to the base to which the supporting mechanism is attached. My motor supporting device consists, generally speaking, in a U shaped spring, to the upper side of which the motor is attached and the lower side of which is attached, through its free end, through a spring connection to a base and my invention is based on my discovery that when the ends of the U spring are connected together by a spring under tension, the vibrations incident to the move ment of the motor are largely taken up and deadened so that they are not communicated through the spring connection to the base with anything like the intensity which would be the case in the absence of the spring connecting the ends of the U spring and my invention consists in its broader feature in the above described construction involving the use of the springs under tension connecting the ends of the U spring. By preference I form my main sprin of an S shape.

My invention will e best understood as described in connection with the drawings in which Figure 1 is a vertical section through a fan actuating apparatus involving my motor support taken as on the line 11 of Figure 2, and

Figure 2 is an end view taken as on the section line 2-2 of Figure 1.

Aindicates the base plate of the apparatus indicated which supports a housing B, one end of which is closed by a plate B through which openings, as indicated at b are provided for the admission of air while the opposite side is provided with an opening indicated at B by which the air is admitted to one side of a double acting fan. 45 My motor support which is secured to the base plate consists, as shown, of an S shaped spring having three parallel fiat portions 0, C and C, connected together by the curved portions indicated at C and C". The lower portion 0 of the spring is secured to the base plate and the motor, indicated at E, is seecured to the top plate C. The portion of the spring plate made up of the flat portions C and C and the connecting curved portion 0 form a U spring, the free ends of which have attached to them a coil helix spring, indicated at D, which spring is adjusted under tension.

F and F indicate the two sides of the double acting fan actuated by the motor which is enclosed in a housing indicated at G, having at its left hand end an opening G for the entrance of air to the fan section F; the housing G receives the air and delivers it through a conduit indicated at- G By the construction described I have found that the vibrations incident to the operation of the motor are very largely taken up in the U shaped section of the spring, the ends of which are connected together by the 7o springs under tension indicated at D, so that comparatively little of these vibrations are communicated through the spring sections C and C to the base.

As illustrated, two spring supports are coupled to support the motor but obviously under certain conditions a single spring support might be used and under other conditions more than two such supports could be employed.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A spring support for a motor comprising in combination a U shaped spring, to one side of which the motor is attached, a spring under tension attached only to the ends of the U spring, and acting to exert a compression force thereon and a spring support for the U shaped spring extending from sprin g ARTHUR J.
