MOUNTING-PLATE.

To all lwhom it may concern:

Be it known that we, HENRY E. BoRGnR and JULIUs H. RICHARDS, citizens of the United States, residing at Newark, in the lighting generators, it isv found dificult tox install an ordinary type of plate or bracket on such engines and get proper alinement of the driving elements, and much time is lost in fitting the bracket or mounting plate.

In order to make installations of this character, it has become common practice to use noiseless chains for the driving medium between aV sprocket, mounted on the driving shaft, such as the crank shaft of the engine and a sprocket mounted on the dynamo, motor, magneto or whatever device is .required to be driven.

Our invention relates to means for overcoming the diiiicultiesencountered by such installation by providing a mounting plate or bracket support that is readily adjustable in two directions. That is, one adjustment for the purpose of b'ringin the driving centers in the same plane an another adjustment for giving the proper tension on the chain or belt, whichever is used.

Another object of our invention is to provide a mounting plate through whose instrumentalities the dynamo, magneto, motor, etc., which is carried on the plate, can be turned back away from the engine in case any work is required to be done on the engine without dismounting the dynamo, motor, magneto or the like from that portion of the plate to which it is attached.

Other and further objects of our invention will be apparent after an inspection of l Specification of Letters Patent. Patented Dem, 11, 1917, Application inea :une so, 1915. serial No. 37,224.

the drawings, which form a part of the V specification.

Figure 1 shows an end'view of an engine of a well known type with a portion of the frame, which supports the engine and having the mounting plate attached thereto and the plate carrying a-motor-dynamo.

` Fig. 2 is a top plan view of the mounting plate with the motor-dynamo removed. A

Fig. 3 is an end elevation of Fig. 2.

Referring now particularly to the drawings in which like numerals refer to corresponding parts in the various figures, 1 represents the front cylinder of a well known shaft of the engine on which is mounted a sprocket wheel 3. 4L is the front cross member ofthe chassis to which is attached the usual fender 5. 6 is asub-structure or base of the mounting plate having legs 7 and 8 rwhich are fastened to the edge of the crank case by the bolts 9, passing through holes 10 and 11 in the legs 7 and 8. and through the corresponding holes which `have already been provided in the flange of the crank case to accommodate the fastening boltspreviously used to secure the two portions of said crank case together. The upper part of the mounting plate 6 has a projection 12 with a hole 13 therein. A bolt 14 passes through the hole 13 and fastens the projection 12 to a lug cast on'the wallv of the engine. Said lug, as is well known, is usually provided on `the frame of engines of this type, and serves which passes a rod 17 that is held in a stationary position in lugs by means of pins 18 and 19. The rod 17 projects beyond the lugs 15 and 16 and on these projections is slidably carrieda super-structure or plate 20 by means of two projecting lugs, 21 and 22. Between the lug 21. and lug 15 there is a clearance space 23. and between the lugs 16 and 22 a clearance space 24. On one pro- 'i 4jecting'end-.of rod 17 is a lock Wa-sher 25 and a nut 26, while on the other end of the rod 17 is alook washer 27 and nut 28, the

type of multi-cylinder engine, 2 is the crank vdownward until thecol the plate 20. It will be readi y purpose of which will be explained later. rlPhe plate 20, as illustrated, contains three holes 29 through which bolts 30 pass into the base of the motor-dynamo 31, which carries a sprocket 32, properly keyed or fastened to the armature shaft. In the forward end of the plate 20 there are two set screws 33 and 34 for the purpose of adjusting the plate 20 up and down. After the entire mounting plate has been installed on the engine and the motor-dynamo 31 or any other device required to be driven, is fastened to the platey 20, the driving chain which has been previously made of'a length practically correct, is put in place and set screw 34 turned down until the proper tension of the chain or belt is obtained. rllhe lock nut 35 is then set up and as an additional precaution, the additional lset screw 33, which carries the collar 36 fastened in position thereon by the pin 37 and which engages threads in the bottom part of the mounting plate 6 is turned ar 36 inches against seen that by manipulating the set screws 33 and 34, an adjustment of the chain or belt is quickly, obtained. Any other suitable means of locking the two portions of the mounting plate together may be used as we do not wish to be limited to any particular method of doing this.

Should it be found that sprockets 3 and 32 be not in proper alinement, then the plate 20, upon which the motor-dynamo 31 is carried can be moved forward or back by manipulating nuts 26 and 28, by loosening one and tightening the other in accordance with the direction required, the spaces 23 and 24 being provided to allow for this adjustment. It will be seen that an important feature of our invention is that these adjustments may be made while the machine is in operation.

Should it be found necessary to do any work on the engine, and the motor dynamo 31 is at all in the Way, the driving chain or belt can be loosened by means of the set screws 33 and 34 or their equivalent, the chain removed from the sprocket 32 and the entire plate 20 with the motor-dynamo can be turned back as shown in the dotted position of Fig. l.

In the particular plate, as illustrated in Fig. 2, only three bolt holes 29 are shown for fasteningl the motor-dynamo 31 to the plate 20, which is shown cut off on one side at an angle. f The object of this is to clear a certain pipe on the particular engine to which this plate is applicable.

It will thus be apparent to anyone skilled in the art that numerous changes and alterations may be made in the details of our mounting plate but these alterations and changes are believed to come within the scope of the appended claims.

i-,afiaeos Having thus described our invention, what we claim is l. In a mounting plate for dynamo electric machines, the combination of a substructure, a super-structure attached to said sub-structure, supporting means for said sub-structure and adjusting means for adj usting the super-structure in two directions with reference to said sub-structure.

2. In a mounting plate, the combination of a sub-structure having lugs thereon and a support therefor, a rod carried by said lugs, a super-structure having lugs adapted to receive said rod, means on said rod for ladjusting said super-structure in a horizontal direction, and means coperatmg between the super and sub-structures for adjusting the super-structure in a vertical d'1- rection.

4f. In combination, a prime mover, a mounting plate attached thereto, said mounting plate having a sub-structure and a superstructure, said super-structure being pivotally mounted on said sub-structure, a mechanism to be driven and means for attaching the same to said super-structure, means for driving said mechanism on said super-structure from said prime mover and means for adjusting. said driving means in two directions.
