Description
Feb. 14, 1933. c. H. SEIFERT GEAR Filed June 27, 1932 INVENTOR [4 Se! eff.
ATTORNEY a WITNESSES Patented Feb. 14, 1933 CHARLES H. SEIFEBT, HEKPS'IEAD, NEW YORK Application filed June 27,
non-metallic material so as to reduce to a minimum the noise of contact between the gear and the metal sleeve as it is moved into and out of mesh.
A further object is to provide a gear of thischaracter having teeth of non-metallic material, strengthened by means of a protector or cap covering one face of the gear, and portions of the teeth.
A'primary object of the invention is to provide a non-metallic gear with improved strengthening means w ereby it may have the necessary resistance to contact in meshing and intermeshing and yet in normal operation when in mesh will be free of any metal contact.
My invention has articularly to do with the construction of w at is generally known in-the art as a pinion gear, constituting ortion of the starting mechanism of a stan ard well-known type, but, of course, the invention in its broadest aspect is not limited to any specific use of. ear.
With these and ot or objects in view, the invention consists in certain novel features of construction and combinations and er rangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawing,--
Figure l is a view partly in ongitudinal' section and artly in elevation, illustrating my improved pinion gear constituting a part of the motor starting mechanism;
Figure 2 is a face view of the gear;
Figure 3 is a view in section through the ear, the view being taken on the line 33 of i ure 1; and
Figure 4 is a fra entary view in section illustrating a modi cation.
The refernce character A is employed to indicate generally my improved gear or gear inion, and in Figure 1 of the drawing, I illustrate this gear pinion as part of a standard type of starting mechanism, which includes an armature or mounting shaft 1 on the medium of the 1938. Serial N0. 819,557.
which a screw shaft 2 is located. The armature shaft 1 is provided with the ordinary torsion drivin sprin 3 connected thereto by a she t spring nut 4.
Gear pinions A of the character illustrated are provided on one face with a weighted disk 5' carrying a drift 'pin 6 with 'a spring 7 thereon for holding the drift pin in operative position.
As the parts above enumerated constitute parts of standard construction it is unnecessar to go into details as to the construction an particularly to do with the construction of gear pinion A which in ordinary practice is 0 metal and which necessitates a certain amount of noise in its operation. r
I construct my improved pinion gear of non-metallic material. In order to give to the gear the necessary strength and rigidity I provide a metal sleeve 8 constituting the center of the gear and 'this sleeve is screw threaded to engage the threaded shaft 2, as clearly indicated m Figure 1 of the drawing.
.Tlie weighted disk 5 above referred to may constitute a separate or integral part of the sleeve 8. To give to the non-metallic gear the necessary protection and stren h I provide a meta cap 9 on the face 0 the gear opposite to the face of the ear where the weighted disk 5 is located. metal cap 9, indicated in elevation in Figure 2 of the drawing, conformsin shape to the shape of the ar and the teeth thereof, and is prov vide at the base of the teeth with securing strips 10 extending to the opposite side of the gear and through openings 11 in the wei hted disk 6 and riveted at its extremities, as s own at 12, to secure the cap 9 against the face of the gear. These strips 10 may have 11 13 at their edges, which bear against the si es of the gear teeth, as indicated clearl in Figure 3 of the drawing, to strength to the teeth or, i' desired, these flanges 13 may be omitted, as indicated in the modification shown in Figure 4 of the drawing.
While I have illustrated what I believe to be the preferred embodiment of my invention, it is to be distinctly understood that operation thereof, as the inventionhas 've a ditional various slight changes may be made with regard to the form and arrangement of parts without departing from the invention, and
hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.
What I claim is: 1
1. A gear wheel having teeth of non-metallic material, a metal protector for the teeth comprising a cap fitting against one face of the gear and conforming to the-shape thereof and flush with. the teeth of the gear, and strips on the protector extending between the teeth of the gear and secured against movement at their extremity. 2. A gear wheel having teeth of non-metallic material, a metal protector for the teeth comprising a cap fitting against one face of the gear and conforming to the shape thereof and flush with the teeth of the gear, strips on the protector extending between the teeth of the gear and secured against movement at their extremity, and flanges on said stri s engaging the sides and base portionof t e teeth.
3. The combination with a non-metallic ear pinion having a weighted disk at one ace, of a protector at the other face of the gear constituting a cap conforming to the shape of the gear, and strips integral with the through the weighted disk and upset at their extremities to secure the protector against the face of the gear.
