GEORGE W. BANDY, OF TALLAHASSEE, FLORIDA.

GEAR- CASE.

Specification of Letters Patent.

Application filed April 16, 1909.

Patented Sept. 28, 190%). Serial No. 490,267.

To all whom it may concern:

Be it known that I, GEORGE 1V. BANDY, a citizen of the United States of America, residing at Tallahassee, in the county of Leon and btate of Florida, have invented certain new and useful Improvements in Gear-Cases, of which the following is a specification, reference being had therein to the accom panying drawing.

This invention relates to gear cases, particularly adapted for use in connection with platen printing presses and the object thereof is to provide a gear case in a manner as hereinafter set forth which is so arranged in connection with the gear as to prevent the paper which is to be printed or has been printed from contacting with the gears of the press whereby soiling of the paper is obviated; to prevent foreign matter from engaging the teeth of the gears so as to retard the operation of the press, and furthermore to 'overcome any liability of accident to the press feeder from contact with during the feeding of the press.

Further objects of the invention are to provide a gear case for the purpose set forth which shall be simple in its construction, strong, durable, efficient in its use, readily po sitioned in operative relation with respect to the gears, and inexpensive to manufacture.

the gears 'ith the foregoing and other objects in I view the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred emb0diment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings, wherein like reference characters denote corresponding parts throughout the several views: Figure 1 is a side elevation of a gear case in accordance with this invention showing the adaptation thereof with the gears of a printing press.- Fig. 2 is a like View looking from the other side. Fig. 3 is a section on line 33, Fig. 1, and, Fig. 4 is a section 011 line l4, Fig. 2.

Referring to the drawings in detail, the case consists of two semi-circular sections 1, 2, each having a semi-circular ofl-set, the off-sets are indicated by the reference characters 1 2 The section 1 is formed with an inwardly extending semi-circular flange 1 which opposes a semi-circular flange 2 extending inwardly and formed on the sec tion The flanges l" and 2 abut. The olfset 1 as well as the off-set 2 being flanged as at 2. The sections 1 and 2 are hinged together as at 5, the means to constitute the hinge is carried by the off-sets 1 2 The sections 1 and 2 are detachably connected together by the latch 6. The flanges 1", 2 2 are formed at one side of the case and are relatively narrow, the other side of the sections 1, 2, being formed with the inwardly extending flanges 2 2 which abut as at 3 and each is cut-away as at 5 to provide a clearance. The flanges 2 are wider than either of the flanges 1 2 The flanges 1 2 and 2 constitute means for inclosing the gear wheel 3 which is mounted on the shaft 4 and meshes with the drive pinion 5 carried by the shaft 6 as at 7. The drive pinion 5 is positioned within the off-sets 1 2 The gear case is fixedly secured in position after it has been mounted to inclose the gear 3 and pinion 5 and for this purpose the paper support 7 of the press is provided with an upright 8 and the upper portion of the case is fixedly secured to the upright 8 by the clamp 9. The lower portion of the case is fixed to the machine frame through the medium of the adjustable clamps 10 and 11. The clamping of the case to the machine frame is had after the case has been positioned to inclose the gear 3 and pinion 5. To provide for the straddling of the shaft .t the clearance hereinbefore referred to is utilized.

When the case is set up in operative relation with respect to the gear 3 and pinion 5 the teeth of the pinion and also the gear are protected not only at the edge but also the sides and owing to the employment of the case in the manner as shown, the paper which is being printed or has been printed is prevented from contacting with the gear or pinion so as to overcome any liability of the paper becoming soiled and furthermore foreign bodies are prevented from interfering with the operation of the gear as well as the pinion and furthermore the case prevents any likelihood of the attendant being injured by the gear during the feeding of the press.

lVhat I claim is:

A gear case comprising two sections, each of saidsections being formed with a semicircular off-set, means at one end of each of the off-set portions for hinging the sections together, means for detachably-connecting the tree ends of the sections together, said means being diametrically-opposed to said hinge, each of said sections and each ot'f-set being provided on one side with an inwardlyextending SGHIl-Cll'CUlfll flange, the flanges ot' the off-sets being formed integral with the flanges of said sections, the flanges of the off-sets abutting and the flanges of the sections abutting ateach end said sections being adapted to inclose a gear Wheel and the off-set portions being adapted to inclose a pinion, each of said sections furthermore being provided on its other side With an inj wardly-extending flange of greater Width than the'flange on its opposite side and abutting at one end, a pair of clamps carried by one of the sections and a clamp carried by the other of the sections, said clamps fixedly securing the case in position and for maintaining the case in operative relation with respect to the gear and pinion.

In testimony whereof I aflix my signature in the presence of two Witnesses.

GEORGE I. RANDY. Vitnesses JOHN Gnmvoo COLLINS, T. J. APPLEYARD.
