v UNITED STATES COB/WILL JACKSON, 01? KALAMAZOO, MICHIGAN.

COMBINED DRILLING'AND GRINDING MACHINE.

Application filed April '18, 1923.

To all whom it may concern:

Be it known that I, OORWILL JAoKsoN, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Combined Drilling and Grinding Machines,- of which the following is a specification.

This invention relates to improvements in combined drilling and grinding machines.-

My improved drilling and grinding machine is especially designed by me for use in garages and the like or' for drilling or other work requiring arotary driven spindle and for valve grinding and the like requiring an oscillating spindle or member.

The main objects of'this invention are:

First, to provide an improved motor driven machine of the class described which is very compact and is readily adapted for use of either its rotary spindle or its oscillating spindle.

Second, toprovide a' combined drilling and grinding machine having few parts and these parts arranged so that they are strong and durable and at the same time may be of drilling and grinding machine in which the moving parts are effectively housed and at the same time are readily accessible.

Fourth, to provide an improved combined drilling and grinding machine having the above advantages which is very simple and economical in its structure.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow:

I accomplish the objects of my invention by the devices and means described in the following specification. The, invention is clearly defined and pointed out in' the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a side view of a structure embodying my improvements, a valve grindi ng tool being illustratedin' position by dotted lines in one driven spindle and a chuck being shown in full lines in the other spindle.

I FigLII is a detail'vertical section on the line corresponding to line 22 of Fig. III,

Serial No. 633,033.

parts being shown in full lines for convenience in illustration. i I

Fig. III is a horizontal section on a line corresponding to line 33 of Fig. II.

Fig. IV is a horizontal section on a line corresponding to line 44c of Fig. II.

Fig. V is a side elevation partially in vertical section of a modified form of my'invention.

i VI is a horizontal section on a line corresponding .to line 66 of Fig. V.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to thefdrawing, I provide a frame or support comprising a body member 1 having a gear box 2 formed in the upper side thereof and a downwardly facing seat 3 for the motor housing a, the motor .housing being clamped in position on this seat by screws as 5 arranged through the flanges 6 on the body member.

The body member 1 is provided with a bearing extension 7 in which the spindles 8 and 9 are mounted in parallel relation, as shown in Fig. II. These spindles 8 and 9 are provided with sockets or chucks 10 and 11 respectively. The socket 11 is internally threaded to receive the stem of a drill chuck shown conventionally at 12. The socket 10 is adapted to receive the shank 13 ofthe catch.v

The spindles are provided with suitable bearing bushings l9.

The motor shaft 20 projects into the gear box 2 and is provided with a pinion 21. The motor housing is provided with a bearing extension 22which fits into an opening 23 in the body member 1 thereby aligning the shaft andsupporting the housing laterally.

In the, preferred embodiment of my invention shown in Figs. I to IV inclusive, a gear 24 having an eccentric 26 on its underside is mounted on the spindle 9 and meshes with thepinion 21 so that the spindle 9 is driven with a continuous rotary movement. The spindle 8 is provided with a crank co ,valve grindingtool 14, and has longitudinal acting with the eccentric 26 so that as the gear iszrevolved an oscillating movement is imparted to the spindle 8.

The top member 27 constitutes a cover for the gear box and is provided with a handle 28 for the manipulation of the machine. The top member is provided with a thrust bearing member 29 for the spindle 9.

This top member is also provided with a chamber 30 in which the switch for controlling the motor is placed, the switch mechanism being shown conventionally at 31.

The electric cable for the motor is intro duced through an opening 32 in the body member 1." I v With this arrangement of parts the machine may be readily adapted for use for drilling or for valve grinding or other purposes requiring oscillating movement.

The machine is very compact and economical in structure, there being relatively few parts and these may be of substantial size.

In the modification shown in Fig. V, the partsare arranged in the same general relation as in the structure described, the gear 33 corresponding to the gear 24L, being a plain gear, the spindle 3d corresponding to the spindle 8 and being extended so that its crank is in a plane above the gear 32. This necessitates a structure of larger dimensions as the spindles must be farther apart in order to permit the spindle 34: to project at the edge of the gear 33. The crank 35 is connected by the link or pitman 36 to a wrist pin 37 on thetop of the gear 33. The crank 35 is longer than the radius of the wrist pin 37 so that the same oscillating movement is secured for the shaft 34 as in the construction of Figs. I to IV, inclusive.

I have not illustrated or described certain other modifications and adaptations which I' contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired. Havmg thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination of a frame comprising "abody member provided with a gear box and having a motor housing seat on its underside and a spindle bearing extension disposed at the side of said seat, a top mom b'er constituting a cover for said gear box and provided with. a hand piece, a motor provlded with a housing mounted on said seat, said motor being provided with a shaft projecting intosaid gear box and having. a "pinion thereon, spindles mounted in parallel relation on said spindle bearing extension to project into said gear box, one of said spindlesbeing provided with a crank, and
