LAMINATED GEAR-WHEEL.

Specification of Letters Patent.

Patented Nev'. 27. 1an.

Application filed March 10, 1917. Serial 119,158,961.

To all 'whom it may concern.'

Be it known that I, JAMES BATTLE, a citizen of the United States, and a resident of Detroit, in the county of Wayne and 6 State of Michigan, have invented a certainl lnew and useful'lmproveinent in Laminated Gear-Wheels, of which the' following is a specification. The present invention relates to -gear wheels, and 4has for an object to provide an improved gear wheel which may be made up of a number of disks or laminee accord ing to the size of 4the gear Wheel. required, to be placed on the gear heel. A An'object of the present invention is to provide a gear wheel of relatively light weigh-tas compared with the width and 'diameter of the gear wheel, and to provide a wheel of this character which may be made entirely by means of punch-press dies, in a single, or several successive operations. `A further. object of the present invention is to provide/a gearwheel which may be of the internal type", which may be of the com- Eound intern `external type, or which may ev of the h type, all of which may be made .by puilch-press dies..

The above, advantages of this invention will be in part understodd and in part described, from the following detailed description of the pres ent preferred embodiment, the same vbeing illustrated the accompanying drawing wheiein:

, Figure 1 is a side elevation of a spur gear constructed according tothe present inven tion.`

Fig. 2 is an edge elevation of the same.

Fig. 3 is a transverse section taken Fig. 4 is aside elevation of a gear wheel of the compound internal external type constructed aicrdmg to the present invention. Fig. 5 it',A a Vtransverse section taken through the same. Fig. 6 is a similar View disclosing a rlighly modid form of the gear wheel of 1 de elevation of a gear wheel e constructed according -to `e present 'inv ntion.

F1g.8 is an ge elevation of the hob gear of Fig; V7, par ly in section, disclosing the the laminas of which the gear wheel is c nstructed.

and various other objects and v vided with Referring Figs. l, 2 and 3, the ear wheel Iis disclosed as comprising four lsks or

laminas

10, 11, 12 and 13, although it is to be understood thatl the gear Wheel may be made up of any desired number of disks.

Aln the present instance, the disks or laminas are disclosed as being of the same diameter, and having spur teeth 14 stamped in their marginal portlons, and registering transversely. A plurality of rivets 15 are secured transversely through the lamina: to connect the same into a unitary body.

Certain or' these disks or lamin, such as the

outer disks

10 and 13, are provided with 'relatively small openings 16 adapted to receive a shaft or the like upon which the gear wheel is to be supported. For ordinary use, these

outer disks

10 and 13 afford an .ample support for the gear .wheel and are capable of withstanding the strain which the gear wheel4 is to be locked to the shaft, a keyway 17 may be formed in the inner niarginal edge of each outer, disk 10 and -13 'at one side thereof.

The intermediate 12 are stamped or cut in substantially ring form with relatively large central openings 18 therein for thepurpose of producing a relatively light gear wheel, and also forthe purpose of economy in material.

As shown in Fig. 6, the shaft-receiving openings 16a may be formed centrally in the intermediate disks or lamin 11 and 12, and the

outer disks

10 and 13 may be proa relativelylarge central opening 18.

In the form shown in Figs. 4 and 5, the disks orjlaminzn may all be provided'with the external gear teeth 14, and the outer disks 10b and 13h provided with the relatively large central openings, andwith internal spur teeth 19 at their inner marginaledges. In this construction, the intermediate disks or laminas 11 and 12 are employed.

tothis drawing, and first to is usually placed upon the same. Ify

disks pr laminas 11 and i The hob gear disclosed 'in- Figs. 7 and 8 offset relation, oli'settingthe disks or lamin i about their axes of rotation. Each two adjacent end disks are provided with relati'vely small shaft-receiving o enings 21 therethrough, and if desired, t e keyways havin 22 for locking the hob gear to n shaft or the like. The rivets 15 are employed for securing the disks or laminin lateral contact for uniting the disks into a unitary body. The'` intermediate disks 20 are provided with the relatively large central openings 23 for' the purpose of reducing the weight of the lipb gear, and alsoeconomizing in the use of the material.

n all instances, it is preferable to construct the laminated gear wheel of sheet meta-l or the lilgl, and where the thickness permits, the diss may be stamped in one operation to provide thccentrul openings therein and alsothc gear teeth at their marginal edges. w

It is of` course understoodthat various changes and mo'l ifications may be made in the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being Within the scope of the following claims.

I claim 1. In a wheel, the combination of a plurality offlat disks, and means for securing the disks in lateral contact-and 'in coaxial relation, certain of the disks having central support receiving openings therethrough vvith` keyways, and certain of the disks having relatively large central openings to reduce the weight off the Wheel.

2. In a wheel, the combination of a pluralitygof flat disks, and means for securing the disks in lateral contact, certain of 'the disks havind-central support receiving o enings therethrough, andcertain other t isks relatively large central openings theret roughl to reduce the Weight of the wheel. f

3. In a gear wheel, Athe combination of V a lplurality ofdisks having spur teeth in their peripheral edges;A and means for securing the disks in lateral contact with the teeth arranged in predetermined transverse lrelation, certain of the disks having cut-away central portions to provide disks of substantially ring form, and certain other disks having relatively small centrahregistering lopenings therethrough for the reception of a support for the gear wheel.

4. In a gear wheel, the combination of a plurality of disks formed with a, punchpress die to rovide teeth in the mar inal edges thereo 4and central o enings terethrough, certain of the dis s belng provided with relatively small support-receiving openings, and certain other disks being ner marginal edges, andl means for securingv said disks in lateral Contact.

G. A compound internal external gear -wheel comprising a' plurality of disks cut to provide gear teeth 1n their outer marginaledges, the intermediate disks being formed with relatively small "support-receiving openings therethrough, and the outer disks having relatively large weight reducii'lg openings formed. centrally therethrougm,

said outer disks being providedv at their i n` ner marginal edges with internal gear teeth, and means for securing said disks in lateral contact Ainto .a unit-ary body.
