SHAFT AND DE'IAGHABLE GEAR.
Application filed November 3, 1924. Serial No. 747,421.
To all whom it may concern:
Be it known that I, WILLIAM H. SoHULzE, a citizen of the United States, residin in the city of Chicago, in the county of (Jook and State of Illinois, have invented certain new and useful Improvements in Shafts and Detachable Gears, of which the following is a specification, reference being had to the accompanying drawings forming a part thereof.
The purpose of this invention is to provide an improved construction of shaft and detachable gear with means for attaching the gear to the shaft, adapted to facilitate disengagement of the gear for repair replacement or for substituting a difierent gear. It consists in the elements and features of construction shown and described as indicated in the claims.
In the drawings:
Figure 1 is a partly sectional view axial with respect to the gear and attaching de- Vice, the same being shown on the shaft which appears in elevation.
Figure 2 is a section at the line, 22.
Figure 3 is an outer end elevation of the attaching device.
Figure 4 is an inner side view of one of the parts forming the attaching device as seen at the plane indicated at the line, 44, on Figure 3.
Figure 5 is an axial section of the terminal gear carrying portion of the shaft.
In the construction shown in the drawings the shaft, A, has a gear centering terminal comprising a conically tapered part, 10, a cylindrical end portion, 11, corresponding in diameter to the least diameter of said tapering part, and a cylindrical part, 12, having a diameter equal to the greatest diameter of the conical part, 10, back of the terminal portion of the shaft, it has two opposite parallel cross slots or grooves, 13, 13, reducing the shaft in cross section to a neck portion, 14, and forming rearwardly facing shoulders, 15, 15. The gear, B, has a central substantially cylindrical bore, 6, which may be tapered so slightly that the taper is invisible in the drawings for a drive fit as hereinafter mentioned, and at one side of said bore there is formed a slot, 79 which may be termed a key seat for an engagement hereinafter described. The attaching device comprises two members, 0 and C identically formed excepting as to a single feature hereinafter particularized. Each of these parts of the attaching member consists of a hollow half bushing dimensioned as a whole,-that is, when the two members are assembled on the shaft--for drive fit in the central aperture, 5, of the gear, B. Each of these members has at the opposite ends respectively semi-circular webs, 16 and 17, the web, 16, at the forward end having a semicircular notch 16 to fit the cylindrical end portion 11, of th shaft, and a web, 17, at
the rear end having an angular or par allel-sided notch, 17, rendering said web forked for engaging the neck,.14c, of the shaft. At least one of the members, and not necessarily both, and as shown, the member, G has struck out from its cylindrical side wall preferably at a point near the rear end web, 17, an outwardly projecting lug, 19, dimensioned for engaging the key slot, Z2 of the gear.
From the foregoing description, it may be understood that the two members, C, C of the attaching device, being applied to the opposite sides of the shaft terminal with their rear end web fork notches, 17 engaged with the neck, 14:, of the shaft and their forward end Web notches, 16*, fitting the cylindrical terminal, 11, of the shaft, the gear may be applied outside the assembled attaching device with the key slot, b aligned with the lug, 19, and upon being driven home entering the lug, 19, in the key slot, the attaching device members will be snugly clamped into engagement with the shaft at the same time that the gear is made rigid by its drive fit with the driving device, and thereby the gear is secure-d rigidly to the shaft against displacement either axially or rotatively.
I claim:
1. In combination, a shaft, a disengageable gear and an attaching device, the shaft having a reduced centering terminal and a transverse reduction forming a non-circular neck and a rearwardly facing shoulder; the attaching device consisting of a two-part hollow bushing, each part having at one end a semi-circular web fitting the reduced shaft terminal and at the other end a semicircular web forked to engage the reduced neck of the shaft, the gear having a central struck lug from one of its members for enaperture dimensioned for drive fit on the gaging said slot. bushing. v In testimon where0f,.I have hereunto set 10 2. In the construction defined in claim 1 my hand at C icago, Illinois, this 29 day of 6 foregoing, the gear having a key-seating October, 1924.
