LiNTER-GIN-RIB MOUNTING;

' f Application filed March-25, 1922; Serial No. 546,672;

T 0 allwhom it may concern Be it known that I, TOLLIVER M. J ONES, a

citizen of the United Statesof America, re-

siding at Birmingham, in the county of Jefferson and State of Alabama, have-invented certain new and useful Improvements in Linter-Gin-R-ib Mountings, of which the-fol lowing is a specification.

My invention relates to an improvemen in the manner of maintainmg gin saw ribs in the breast of an oil mill linter gin, or

other gin.

The object of my invention more particu larly is to design the ribs and the'top and bottom rails to which it'has heretofore been the practice to bolt'them' so thatthe ribs can be very readily and easily attached and detached without the use of attaching screws inthe ribs.

More-particularly my object-is to so design the rails that the ribs will interlock with and be properly centered by the rail without relying upon the use of screws to that end. I

that they are held positively andrigidlyLin their correct operating posit1on,thus avoiding the tendency of displacement ofthe ribs as their clamping screws wear, which has heretofore. been an"'ob ect1onable operating condition.

A further object is toprovide individual adjustable clamps, one of which is adapted to hold each rib interlocked with both top and-bottom rails, thus permitting a, quick and easy removal of anydesired rib.-

My invention moreover comprises the novel details of construction and arrangements of parts, which in their preferred embodiment only are illustratedin' the accompanying drawings, to which reference is made in the following specification'wherein I have sought to describe my inventionwith suflicient particularity for thoseskilled in the art to practice the same.

Referring to the drawings Fig. 1 is a vertical 'cross-sectional'view through the top and bottomrails of the breast of an oil mill linter gin,* the 'saws being shown in dottedlines and gin parts being omitted. v I

Fig. '2 is a planview partially broken away of one end of the bottom rail showing several of the ribs mounted'thereon. Y v

'Fig. 3 is a cross-sectional view take'n'on the line 33 of Fig. 1. I

. spondingthe other Fig. 14 is a perspective view of a portion rail showing several of one-end of the top ribs-"interlocked therewith. I

Similar reference numerals refer to simi' lar parts throughout the drawings. The ribs are-alike and each comprises a curved body portion 1 which may be of any standard design and shape. At itsupperend the rib is provided with a toprailen gaginglug 2-which in transverse cross-sec- 1 term" tion is tapered so as to fit snuglybetween the spaced taper shoulders 3011 the top rail 4c and engage the rail. The taper I seats formed on their-ail between the shoulders 3 thus serve' 'to positively and accurately cen v ter the upper=ends of the ribs on the top rail 4. Each top lug 2 is providedwith a shoul der 5 havinga bevelledtop face adapted to i l v engage and interlock under the downwardly bevelled bottom face 6 of the top rail 4.

At its lowerflendeach rib is providedv with i a bottom rail engaging lug 7 which tapers in its underside in the'same manner as the V lug 2 and is adapted to conform'to andfit A further object is to so'mount the ribs snuglyinto one of a series of taper seats formed in the bottom rail 8 by the counter to provideat-their lower ends a shoulder 11 15, there being one for each ofit'he'ribs. Each clamp has its upper edge undercut by a bevelled; face 516 which overlaps a correy bevelled face at the bottom endt of the rib lug 7. In operation, a

against which'the lower end ofthe l'ugsseat. squarely. The shoulders 10 project substantially above thebottom portion of the rail;

. which is provided with a series of bolt holes 3 l2, one in line'with the center of each seat 9. These holes receive screws lemmas/01 k in elongated slots 14 in individual slide clamps gin saw rib is inserted between'the appropriate saws and its upper lug 2 iscaused to seatrbetwjeen thegde'sired shoulders 3 in the top' rail and its bevel shoulder 5 is caused to; interlock .with the bevelled botto'm edge 60f the top rib. The

lower lug 7 of the rib is then placed in .its

appropriate seat 9' in the bottom rail 8. and

by shifting its respeetive clamp -l5 'into an:

rib can be both forced upwardly and held jgagement with the taperendof its lug 7 the Y screw 13 is tightened and the rib is locked in position.

l' l hile this arrangement may be utilized for all ribs in the gin breast, Iwould prefer to have one or two ribs at each end of the breast directly attached by clamp screws to the top and bottom rails so as to hold the bottom rail in place while removing the cast iron heads of the gin. To this end I show a bolt hole provided in an end seat or seats in the top rail 4 and each adapted to receive a clamp screw 17 passing through an opening therefor in the upper lug of the end rib or ribs. Inlike manner I provide in one or more of the end seats of the bottom rail a screw hole adapted to receive the bolt 17 and in such case the hole 12; in alignment therewith may be omitted if desired, but there will be no objection to utilizing the" clamps'lS' even on such endribs which are directly bolted to the top and bottom rails.

By the arrangement shown have accurately centered sea-tswhich are all similar and these seats enable the ribs to be very quickly assembled, accurately centered and positively held during: operation. Also the engagement of the clamp lugs :15 forming the retaining means for the ribs will not wear andthe ribs having taper interlocks in several direct-ions at both ends, the ribs will be positively "and etfectively held in operating position. They can be readily removed at anytime. by

loosening their respectiveclamp screws 18 and. letting the clamps drop away, whereupon the bottom ends of the ribs'can be lifted out of the base rail seats and drawn downwardly to disengage; the upper lugs from the top rail. The maintenance or accurately centering of the ribs and their very positive mounting give a superior grade and increased quantity of lint.

Though I have described with great par- ,ticula-rity the details of the embodiment of the invention herein-shown, it is not to be construed that I am limited thereto as changes in arrangement and substitution of equivalents may be made" by those skilled in the artwithout departing from the invention as defined in the appended claims.

Having thus described my invention, whatI claim as new and desire to secure by Letters Patent, is

1. A rib rail for gin saw breasts havingindividual taper rib. seats formed therein. 2. A rib rail for ginsaw breasts having a bevelled bottom edgeand integral rib spacing means on its front; face, in combi nation with ribs having bevelled shoulders adapted to interlock with said bevelled bottom edge and ends adapted to engage said spacing means. I

3. A rib rail for gin saw breasts having. spaced raised rib centering shoulders thereon.

the ribs all 7. A rib rail for gin saw breasts having a series of equi-distantly spaced countersunk taperingrlb seats formed therein, and

a clamp means adjustable to overhang th seats.

8. In combinatlon, a ribrail for gin saw breasts having a serljes of rib seats, and iiidividual adjustable rib clamps adapted to engage and secure ribs in said seats.

9. In combination, top and bottom rails for the ribs of a gln saw breast, means forming aligning rib seats in said rails, and

gage the ribs and force them into interlocked relation with the bevelled edge of the top rail.-

11. In combination, a: top'rib rail having a bevelled edge, ribs having a top bevel shoulder adapted to interlock under said edge, and a bottom rib rail having. a series of individual rib clamps adjustable to .engage the ribs and force them into interlocked relation withthe bevelled edge of the top rail, said clamps having their rib engaging ends adapted to both abut against and overhang the bottom rib ends, for the" purpose described.

12. In combination, a top rib rail having" a series of rib seats and a bevelled edge downwardly inclined in; line with each seat, a bottom rib rail havlng a' series of rib seats aligning with those on the top rail, ribshavingend lugsadaptedto fit into the 'topand bottom rail seats and having. an
