GEARING.
Specification of Letters Patent.
Patented Sept. 24, 1912.
Application filed September 27, 1909. Serial No. 519,810.
To all whom it may concern:
Be it known that I, EUGENE Coon, a citizen of the United States, residing in the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Gearing, of which the following is a specification.
This invention relates to improvements in gearing.
The objects of this invention are, first, to provide an improved gearing adapted to be manually driven, which is very compact, and, at the same time. one in which the driven shaft may be driven at a very high rate of speed. Second, to provide an imroved 'earim in which the ears are all b h b completely inclosed, and, at the same time, the structure is comparatively light in weight, and is readily portable and adapted to be attached to various forms of supports,
such as tables or hand cars. Third, to provide an improved gearing in which the gear is inclosed and the bearings are so arranged that the shafts supported thereby are very efiectively supported so that the structure is very durable.
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 structure described constitutes one effective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.
The invention is clearly defined and pointed out in the claims.
A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:
Figure 1 1s a perspective View of the outer s1de of a gearing embodying the features of my invention, the same being shown mounted on a table. Fig. 2 is a perspective view of the inner side of the structure shown in Fig. 1. Fig. 3 is a detail edge view, the casing being shown in vertical central sec- 5 tion. Fig. 4 is a perspective view of the tool rest support. Fig. 5 is a longitudinal section through the drill holder, a drill being shown in position therein. Fig. 6 is a transverse section therethrough taken on a line. corresponding to line 6--6 of Fig. 5.
Fig. 7 is a detail vertical section taken on a line corresponding to line 7-7 of Fig. 1 showing details of the adjustable supporting means for the tool rest support.
In the drawings, 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 the drawing, 1 represents the grinding wheel and 2 the shaft thereof. The grinding wheelshaft 2 has a pinion 3 thereon, the pinion being preferably formed by milling the same in to theshaft. The shaft 2 has a bearing portion adjacent to the wheel and also a reduced bearing portion 4 at its outer end. The crank 5 is mounted on the crank shaft 6 on which is a gear 7. This gear 7 is connected to the pinion 3 of the grinding wheel shaft through the gear 8 and the pinion 9, the pinion 9 being arranged on the shaft 10 for the gear 8. The connecting gear 8 is a comparativelylarge gear as illustrated, that is, it is large in proportion to theother gears or pinions described. The pinion 9 is preferably milled into or formed integrally with the shaft 10. The gear 7 is arranged at the side of the gear 8, see Fig. 8. These gears are inclosed in a casing consisting of a pair of plate-like members 11 and 12 respectively. These casing members are provided with opposed flanges 13. The bearings for the shafts described are formed integrally with these casing members. On the casing member 12 is a housing 14 for the gear 7. This housing projects from the plate-like casing member 12 like a boss. From this housing projects bearing 17 for the outer reduced end 4 of the grinding wheel shaft. Projecting from the casing member 13 are bearings 18 and 19 respectivelv for the inner ends of the connecting gear shaft 10, and the grinding wheel shaft 2. The bearing 15 projects outwardly beyond the end of the bearing 17 so that the crank 5 clears the bearing 17, also this long bearing provides a suitable support for the shaft 6. The bearing 19 projects outwardly beyond the bearing 18 so that the grinding wheel 1 clears the bearing 18 and also this provides a long bearing for the shaft 2 at each end so that the grinding wheel is effectively supported and the on the shaft minimized.
On the casing member 11 are laterally projecting arms 20 and 21. These arms are disposed triangularly as shown in Fig. 2, the lower arm being centrally arranged and also arranged to project downwardly. The arm 21 is threaded to receive the clamping screw 22. The casing member 11 is pref erably provided with ribs 23 which extend between the arm 21 and the arms 20. These ribs not only reinforce the casing so that it is effectively supported but also are adapted to engage the object upon which the casing is clamped so that it is very securely mounted and the tendency to twist is obviated.
1 preferably provide a tool rest support- 24. This tool rest support 24 is preferably U shaped to embrace the edge of the grinding wheel as shown in the drawing, one arm of this support is longitudinally slotted at 25 to receive the clamping bolt 26. This clamping bolt is arranged through a lug 27 provided therefor on the inner casing member. The slotted arm of the support is preferably countersunk at 28 to receive the nut 29 of the clamping bolt so that the bolt can be readily loosened and tightened by means of a wrench applied to its head.
I preferably provide a fixed tool rest 30 and a swinging drill holder31. The fixed tool rest is mounted upon the end of the support and is provided with a cross head 32 as clearly appears in the drawing. The drill holder 31 is provided with a bearing stem 33 which is adapted to be arranged in the bearing holes 34: in the outer arm of the support. a pair of holes being preferably provided so that the drill may be presented to a greater surface of the grinding wheel, thatis, more of the side of the grinding wheel can be utilized. The drill holder 81 is preferably V shaped in cross section and is provided with a tail piece 35 through which the screw 36 is arranged and adapted to be adiusted to engage the end of a drill as 37.
The two parts of the casing are fitted together so that they form an oil tight casing.
My improved grinder is very compact in structure, and, at the same time, the gears are so arranged that the grinding wheel may be manually driven at a very high rate of speed. The gears are entirely incased and protected, not only from the dust of the grinding wheel, but also from liabilty to injury from blows or the like. While the casing isadapted to support the bearings, the bearings for the various parts are all of such length that the shafts are very effectively supported.
I have illustrated and described my improved grinding machine in detail in the form in which I have embodied the same in practice and which form I find to be highly satisfactor n I am aware, however, that it can be considerably varied in structural details without departing from my invention, and I desire to be understood as claiming the same specifically in the form illustrated as well as broadly within the scope of the appended claims.
