BY I m WITNESS ATTORNEYS rarsur GORDON F, CANE, 0F OAKLAND, CALIFORNIA, ASSIGNOR TO AMERICAN AUTOMATIC LOOK AND LIFT COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.
GEAR BACK.
Application filed December a, 1920.
T 0 all 10 7mm it may concern Be it known that I, GORDON F. CANE, a citizen of the United States, and resident of Oakland, county of Alameda, and State of California, have invented a new and useful Gear Rack, of which the following is a specification.
My invention relates to a novel form of a rack which is adapted to be engaged by a gear or the like for enabling one to be moved with respect to the other.
Some of the objects of the invention are to provide a rack which is very light in weight, exceedingly simple in construction, and low in the cost of manufacture.
The invention possesses other objects and features of advantage, some of which, with the foregoing. will be set forth in the fol lowing description of the preferred. form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.
deferring to said drawings:
Figure 1 a side elevation of the rack.
Figure 2 is a longitudinal section of the rack showing it in engagement with a gear.
Briefly expressed the rack in its present embodiment comprises a continuous piece of wire or the like which is bent in substantially plaited convolute form.
A detailed description of the rack as illus trated in the drawings follows:
The rack comprises a single continuous metallic strip of wire 2 of a more or less flexible nature and bent in the form of what may be broadly termed a plaited convolute. The straight sections 3 of the convolute structure are preferably parallel to and spaced equidistantly from each other and are arranged to contact with the teeth l of. the gear 5 when the latter is in mesh with the rack.
Specification of Letters Patent. Patented Aug. 1, 1922.
Serial No. 428,416.
The wire structure is preferably secured by any suitable means to a base or backing member 7 in order to afford the structure added rigidity. The base 7 is provided with a. longitudinal groove 8 of narrower width than the wire structure and is arranged to lie centrally of the broa-dsides of the said structure when the latter is positioned there on. In this manner when the gear meshes with the rack the teeth 4 if necessary may extend into the groove thereby enabling the use of a wire of very small diameter with out impairing the proper meshing of the members.
I claim:
1. In a rack for a gear. a base having); a lon gitudinal opening, a continuous wire bent in substantially plaited convolutions secured to said. base and overlying said opening whereby the teeth of said gear may engage in the straight sections of said wire and extend into said opening.
In combination with a gear a rack comprising a continuous wire bent in substantially plaited convolutions, the straight portions of said wire being" equidistantly arranged and parallelly disposed with relation to each other and adapted to be engaged by said gear.
3. In a device of the class described, a base having a longitudinal groove, a continuous wire bent in substantially plaited convolutions secured to base and arranged thereon with each of the straight portions of the wire lying transversely across said groove and successively disposed longitudt nally thereof and a gearhaving teeth adapted to engage in said convolute memher and partially extend into said groove.
4:. A gear rack comprising a continuous wire bent in plaited eonvolutions.
In testimony whereof, I have hereunto set my hand at Oakland. California. this 2nd day of November 1920.
