Specification of Letters Patent.
Patented May 27,1919.
Application filed September 23, 1918. Serial No. 255,247.
To all whom it may concern:
Be it known that I, MORTON W SON, a citizen of the United States,res1d1ng at 'Woodbury, in the county of Gloucester, State of New Jersey, have invented'a new and useful Portable Driving and Speed- Reducing Device for Reamers,'Drills, and
the like, of which the following is a speci fication.
In shipyards, machine shops, boiler shops and the like it has heretofore been the practice reaming certain classes of Work in.
close quarters or inaccessible places to actu- 1, and
ate the reamer or roughing reamer by hand, on account of the inability to rotate the same mechanically, and my present invention is designed to obviate the foregoing ob ect1ons and to utilize a' high speed electric or pneumatic or other motor for the purpose of rotating a reamer, roughing reamer, drill] chuck and of said shaft or spindle to the desired extent and to transmit and impart it to the reamer, drill or other tool which it is desired to rotate.
To the above ends my invention consists of a novel construction of. a drivlngand speedreducing mechanism for a reamer, drlll or the like, the same being provided with a suitable frame work carrying the spindle, which is adapted to be inserted in the rapidly rotating chuck of the electric, pneumatic or other motor, and a novel collocation of gearing, the last member of the train of gearing being equipped and adapted to receive an actuate the reamer or other tool to be driven.
For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at pres ent preferred by me, since the same will be found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of- C. HUTCHIN- which my invention consists can be. variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instru mentalities as herein shown and described.
Figure 1 represents a plan view of a driving and speed-reducing mechanism for reamers, drills and the like embodying my in vention.
Fig. 2 represents a section on line 2-2 of Fig. 3.,certain of the parts being shownin elevation.
Fig. 3 represents a side elevation of (Fig.
Fig. 4 represents on an enlarged scale a section on line 4.-4 of Fig. 1.
Similar numerals of reference indicate corresponding parts.
Referring to the drawings-- 1 designates my novel construction of drivmg and speed-reducing mechanism, the same compr sing a frame work composed of a pair of front and rear plates 2 and 3 respectively, which are held in assembled position by means of the bolts 4 and 5, the bolts Ibeirig through bolts and the bolts 5 being preferably rivet bolts, which are provided with the flanges or shoulders 6 which in conjunction with the distance piece 7 seen at the left of Figs. -1 and 2 serve to hold the plates 2 and 3 in proper assembled position with respect to each other. 7
i 8 designates a driving shaft or spindle 'which is preferably tapered as indicated at 9 for the purpose of ready engagement with the tapered socket'of a'chuck or other appropriate part of the prime motor or drivin member (not shown). The shaft or sp1ndle8 is provided with a reduced portion asindicated at 10 which revolves in the bushing 11 located in the bearing 12 and suitably supported from or connected with the framework.
13 designates a bevel gear, or beveled driving pinion, having a hub 14, which is pinned or otherwise secured at 15 to the reduced portion 10 of the shaft orspindle 8, so that the latter and said bevel gear 13 will rotate in unison. The bevel gear is in .mesh with a bevel gear 16 or beveled driven pinion, I
which is pinned or otherwise secured to the driven shaft 17, the ends of'which revolve in the bushings '18 and 19 which are respectively supported on the front and rear plates 2 and 3.
20 designates a pinion or driving spur "gear which is preferablywformed" on 'or' in tegral with or applied to the shaft 17, and meshes with the driven spur gear2'1, the hubs or ends 22 of which revolve in the bushings or bearings 23 which are respectively located in the front and rear plates 2 and?) ofthe frame. 1
24 designates a squared,'or polygonal socket, axially formed within the body of the driven spur gear 21, which is adapted to receive the squared or correspondingly formed end 25 of the reamer or other boring tool 26 as seen dotted in Fig. 1, said square hole 24 extending throughthe entire length of the spur gear 21, so that the squared shank of the reamer, or boring tool may be fedor forced into thework by a feed screw acting along the .axis of the reamer and applied at the endof the reamer shank (not shown). The reamer is preferably of the construction shown in my contemporaneously pending application, .filed Aug, 31,
Serial No. 252,136, but it will be evident;
that any other desired form of reaming or boring tool may be utilizedin connectionwith m rapidly rotating electric, pneumatic or other motor, it is obvious that its rotation will be imparted to the beveled driving pinion 13, which latter will rotate the beveled driving gear 16 and the driving spur gear 20,..the rotation of the'latter being imparted to the driven spur gear 21 and therefrom to the reaming or boring tool 26, the high speed or rotation of the prime motor. being," through the calculated dimensions of thegears, reduced and the torque created'correspondingly increased at the desired point,
as will be evident to those skilled in the art. My device is especially applicable to the reamer 26 illustrated in Fig. 1, when it is.
desired to use it in close quarters or in inaccessible places where reamin has heretofore been done by hand and have found that it is especially adapted to many situationsin shipyard work where the reaming has heretofore been done by hand, since the operation can be done mechanically with my novel device with a great saving of time and labor.
' It will beunderstood, of course, that my and 8 ur novel driving and speed-reducing device is very light, durable, and self-contained, and
thatbeing portable it can be readily applied to reaming, boring and the like operations in many locations heretofore inacces- Slblfi for mechanically dr1ven-rean1ers. By
the employment of the distance'pleces 7, and the bolts 5, having theshoulders (whereon, in conjunction with the plates 2 and 3,
' a very light and rigid frame work is produced, which Will cause the gears at all times properly to mesh and is portable and can be readily taken apart or dismantled when desired for the purpose of inspection or repairs, or to replace 01-1 inspect any members of the train of gearing, or'their bearings-or their adjuncts. It will now be apparent that I have devised a novel and useful construction vof a new and useful portable driving and speed reducing device for reamers, drills and the like, which embodies the 4 features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present in stance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results', it is to be understood that the same is susceptible of modification in various particula'rs without departlng from the spirit or scope of the invention or. sacrificingany' of its advantages.
Havingfthus described my invention,what I claim as new and desire to secure by Letters Patent, is'z- 1. In "a device of the character stated, a
' framework having a. spur, gear 'rotatably mounted therein and having an axial p0- lygonal socket extending therethrough for the reception of the shank of'an implement to be rotated, a driving spindle extending at an angle to said gear and mounted in bearin on'saidframework, a bevel pinion on sai driving spindle, and speed reduc ing gearing intermediate said bevel pinion ear.
2. driving and speed reducing device, comprising a driving spindle, a beveled drivingv pinion thereon, a driving shaft at an angle to the axis of said pinion, a beveled driven pinion on said driving shaft engagedwith and driven by the beveled driving pinion, a spur gear also" 011 'S&id' driving shaft, a'com'binedspur gear and driven shaft element interiorly bored tov form a socket to receive and rotate a boring implement, saidspur gear being engaged with and driven by the spur gear on the driving shaft.
3. In a device of the character stated, a
