UNIVERSAL HOLDING-BRACKET' FOR POWER UNITS.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed April 20, 1918. Serial No. 229,872.

T 0 all whom it may concern:

Be it known that l, MILTON M. KOHN, a citizen of the United States, residing in borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Universal Holding-Brackets for Power Units, of which the following is a specification.

My present invention relates to a universal holding bracket for holding in operative position certain desired forms of power units such as electric motors and the like.

Another object of the present invention is to provide insuch universal bracket a suitable frictionless bearing whereby the power unit grasped therein may be provided with an additional bearing, forming, substantially, a foot-step bearing for such motors when the device is operated in a vertical position.

Another object of the invention is to provide suoli adjustable motor holding means with a simple and efficient means of adjustment and lock for all adjusted positions.

A further object of the invention `is to lprovide means on the'said devicewhereby any standard type of electricv motormay, withinv limits, be firmly'held between the grasping-means without it being necessary to provide thehousings or other parts of such standard motors with a special coperating gripping means( On the other hand,

where 1t is deemed advisable, coperating gripping devices may be provided upon the said motors. v Y j Another object of the invention is to provide means on-esaid gripping device of an extremely simple nature whereby the gripping holder maybe readily and adjustably appliedto any form of base or other supporting means so that such meansv will be uni-` versally adaptable. j

These 'and other features, capabilities, and advantages .of the invention will appear from the subjoineddetail description of certain specific embodiments thereof, in 'which- Figure 1 is an elevation partly in section of one embodiment showing a motor anchored thereto. j

AFig. 2 is a small section substantially on the line 2.-?. of Fig. 1.

Fig. 3 is an elevation of another embodiment in which the fingers have plain surfaces.

` above this, there is also provided a pivot bracket 15 upon which is mounted the gripping. arms 18, the said pivot bracket being provided with its own locknut 14.

The bracket 15, when used for supporting i a motor or the like, is provided with an annular recess or seat 16 at its free end, in the present instance the upper end, to receive the thrust-bearing A of usual construction which acts as a foot-step bearing for the supported device, in which coperates the shaft B of the motor M Fig. 1. Laterally extending from the bracket 1 5 are provided the pivot lugs 17, for pivotally mounting thearms 18, the lugs being arranged inV pairs to receive an arm 184 between them with a pivot pin 19 extending through a pair of lugs 17 and an arm 18.

There are provided preferably three such arms 18, spaced'equ'idistant, each arm having a finger portion 19 `which coperates with the finger portions of theother arms and with the device tobesupported, and each arm having a fulcrum portion 20 to coperat'e with the fulcrum nut 13. The linger portions 19 in the embodiment illustrated in Fig. 1, may have inner corrugated faces 21 to increase their graspingefiiciency and are shown engaging corrugated engaging plates C .formed on the motor M. The lever arms 20 have inner fulcrum nut engaging faces 22 to engageithe wedging face 23 of the fulcrum nut 13, preferably formed conical as illustrated. v

In operation, assuming that the bracket 15 has been set inplace on the threaded portion 11, the locking nut 14: secured up thereagainst, the thrust-bearing A placed in the seat 16 of the bracket 15, which adjustably supports the thrust-bearing A, the motor located with its shaft B disposed in the bearing A, and the corrugated plates C registering with the linger portions 19,-the

sov

fulcrum nut 13 is then screwed-'up with its wedging face 23 engaging the faces 22 of theV lever arms 20 until the required tension is produced, whereupon thel locking nut 12 is secured up against the fulcrum nut 13 and the support is ready for use.

The embodiment illustrated in Fig. 3, is substantially the same as that illustrated in Fig. 1, except that the finger portions 2i are provided with plain faces 25 instead of the corrugated faces such as the faces 21 of the finger -portions 19. Y

In the embodiment illustrated in Fig; 4, a-inger portion 26 is shown which has an adjustable cone point 27 mounted therein forengaging the device to be supported.

In the embodiment illustrated in Fig. 5, a linger portion 28 is shown provided with a half round bore having aseat 29 for receiving the lower end of a screw 30 which engages t'liethreads of athalf rouirdrece'ss 31 formed in the device to be supported, and is anchored i-ntposition between the device to be'supported and the finger portion 28v as shown. With thisarrangement, it i-s possible to adjust thel alineineiit of the motor axis relative to the support axis without disturbingtli'e tension of the supporting` member;

Iii-the embodiment illustrated in Fig. 6,v

the ybracket 32 is not directly threaded to the threaded portion ofl the supportingmember onstenr 10, as is the case with the bracket 15 of theeinbodiment illustrated in Fig. 1. In this embodiment, the bracket 32 is threaded onto an extension 33 formed onl a cup 84 provided with a seat 35 for receiving the thrust-bearing 36, the extension 33 being threaded to the threaded portion 37 of the supporting member; By this arrairgei'nent,

itwill thus be possible to adjust the distance and bearing between the supported power unit andthe supporting member without disturbingin any way the adj ustment' alinement, axial orotherwise, of the supporting and supported members. j

While I have nbtz shown any means of supplying: oi'l to the thrustv bearing A, it isobviousthat any well knownmea-ns of supplying such lubrication' may be employed.

As previously noted, in order to render my gripping device of extremely simple nature so that it may be readily 'and adjustably appliedto a ceiling, desk, wall, Vor other desirable form of base, ornamental or other- Wise, the lower port-ion of the support is arranged in a stem form as at 10, Fig. 1, said stem being either cylindrical or square. It is obvious that the various forms of bases above referred to need only have a suitable bore to receive said stem'into which it may be rigidly attached by any suitable fastening means ofthe customary type.

It is obvious that various changes and modifications may be made to the details of construction without departing from the spirit of my invention, or exceeding the scope of the claims".-
