COMPENSATING GEARING.
To all whom it may concern: p
Be it known that I, DONALD D. ORMsBY, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and usefulfCompensati-ng Gearing, of which the following is a specification.
This invention relates to compensating gearing and has for its object a gearing in;
In describing this invention, reference is had to the accompanying drawings, in which like 7 characters designate parts in all the views.
Figure '1 is a horizontal sectional'view through my compensating gearing, the con- 7 tiguous part of the driving shaft and pin ion thereon being also shown.
Fig. 2 is a sectional view ht angle to Fig. 1.
Figs. 3 and 4 are,.respectively, face views of the opposing gears 'of the gearing.
Fig. 5.is a developed view of the periph cry of one ofthe compensating pinions.
Figs, 6 and 7 are detail views of modified form of my invention, Fig. 6 being a section-through the opposing gea'rsandthe "compensating pinions, and Fig. 7 a View of the periphery of the opposing gears.
This gearing comprises, generally, a drlving element or'casing, opposing gears, one
having teeth inclining to the right and the; other having teeth inclining to the left, and
compensating pinions each having right and left helical teeth meshing with the teeth of said gears. I
The gears here shown are whatfor convenience I have called aright crown spiral gear and a left crown spiral gear, ,and the teeth of each compensating pinion are formed by cutting right and left helices which intersect, so that each tooth is provided with right and left hand faces, that is, faces arranged in helices 'cut in opposite directions, said faces coacting with the teeth of the spiral crown gears respectively. This corresponding taken at a.

cesses 7, formed in opposing faces ofthe.
margins of the sections 1, 2 and the sections 1, 2 and 3 are j held together by suitable means, as screws 8, extending through the margins of the sections 1, 2 and through the arms 5. The section 1 has secured thereto a suitable gear ring 9 which meshes with the driving pinion 10.
. 1 1 anol 12 are the crown spiral gears which are in the form of disks having teeth on their opposing sides arranged in plane spirals, the teeth having faces 11 and 12?,
the teeth of the gear 11 being right hand or progressing or inclining in a clockwise 'di rection, and those of the gear 12 being left hand or progressing in an anti-clockwise direction. teeth of the compensating pinions when the vehicle is traveling forwardly and turning to the left, but when the vehicle is backing up and turning to the right so that the com-- pensating gear is in action, faces 11*, 12 of the teeth coact with the teeth of the pinions. Each of the gears 11 and 12 is formed with a hub 13 which is journaled in a suitable bearing 14: in the section 1 or 2 and which receives the ends of a shaft section 15hr 16. The driving members of the mo-' tor vehicle are mounted on the outer ends of the shaft sections, as will be understood by those skilled in theiart. The side sections 1, 2 of the casing are also provided with hubs 17 mounted on the shaft sections 1.5, 16,01 on suitable bearings.
18 are what for convenience their axes extending crosswise ofthe casing I have called, 7 right-and-left hand helical pinions carried by the central section 3 of the casing with- .in the "recesses 6 and being arranged with The faces. 11 12 coact with the r or of the gears 11 and 12," and as here 7 shown, they are mountedupon spindles 19 extending through the recesses 6 and'located' midway between opposing faces of the gears 11, 12 and parallel to said faces and in circular series around the axis of the dif-' ferential gear, that is, the aXis of the shafts The faces of the teeth of each gear 18 are out along two spirals or helices, as seen in the developed view in Fig. 5, which helices progress in opposite directions, thereby forming on the teeth, right and left hand faces 20, 21, the faces 20 coacting with the faces 11 of the teeth of the gear 11 and the faces 21 coacting with the faces 12 of the teeth of the gear 12. Each tooth of the helical pinions is also formed with rear faces 20, 21 which, during rearward rotation of the gears 11 12 and when the compensating gearlng is in action, coact with the faces 11 12 of the gears.
Although the pinions are shown as mounted upon spindles 19, they may be mounted or supported in any other suitable manner. Usually, for the purpose of facilitating the holding of the spindles in position, the spindles are paired and the contiguous 01 meeting ends of each pair of spindles are lapped and secured together in any suitable manner, as shown at 22.
The inclinations of the teeth of the crown and spiral gears and the helical pinions, are such that the pinions do not lock but compensating action'of the pinions takes place practically only when the Vehicle is turning a curve and does not take place at all times when the ground wheelshaveunequal trac-v tion, as is the case in-ordinary compensating gears. Instead of crown spirals, other gears having teeth inclining in opposite directions maybe employed, as shown in Figs. 6 and 7,
in which worm gears 23, 24 areshown, the teeth of which are inclined in opposite directions, and with which mesh'teeth of a helical pinion 25 having right and left teeth.
This gearing is particularly advantageous in that it consists of a few number of parts, and that owing to the arrangement of the teeth'of the crown gear and helical pinions,
compensating action takes place, that is, the pinions transmit driving motion to the outside wheel of a vehicle, and owing to the fact 7 that a right-and-left hand helical gear is used to mesh with the crown spiral gears, it is unnecessary to reverse the movement .of the inter osed pinions. What i claim is p 7 1. A compensating gearing comprising a casing including opposing side sections have V the peripheral flanges of the side sections,
ing opposing'peripheral flanges, an intermedlate section having a transverse recess therethrough and flanges extending between and means extending through the flanges of the side sections to clamp the same together onto the intermediate section, opposing gears located in the side sections, and a compensating pinion supported in the recess in series and in pairs, the spindles of each pair 7 being arranged end to end, and having their meetingends secured together, substantially as and for the purpose set forth. r A compensating gearing comprising a casing including opposing side sections and an intermediate section between the side sections including a hub and outwardly eXtending arms formed with recesses, opposing gearsmounted in the side sections, compen 'sating pinions mounted in the recesses,
spindles upon which the pinions are mounted,-the spindles extending between the gears and arranged in circular series and in pairs, and the spindles of each pair b61112; anranged endtoend and secured together, substantially as and for the purpose specified;
4. A compensating gearing comprising a casing including opposing side sections and an intermediate section between the side sec tion, the intermediate section being formed with recesses, and fastening means passing through the margins of the side sections, and through the intermediate section, crown spiralgears mounted in the opposing side 7 sections, and compensating helical PlIllOIIS mounted in .the recesses and having teeth formed with right and left faces for engaging with the teeth of the crown spiral gears.
respectively, substantially as and for the purpose set forth. v t V In testimony whereof, I, have hereunto signed my name in the presenceof two attesting witnesses, at Syracuse, in the county of Onondaga, in the State ofNew York, 7
