ROLLER-TABLE.

Specification of Letters Patent.

Patented Jan. 1, 1907.

To all whom it may concern:

Be it known that I, CLARENCE L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Roller-Tables and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in roller-tables for use in connection with metal shears, the object of the invention. being to provide a table that can be moved away from the shear so as to permit of the discharge of the severed ends and all undersized parts and be moved up to the shear in a position to receive the articles as they pass through the shear.

A further object isto provide an adjustable gage adapted to overhang the roller-t able and capable of being moved so as to permit the roller-table to drop and also to permit of the articles thereon to be carried throughout the length of the table. With these ends in view my invention consists in the parts and combination of parts, as will be more fully explained and pointed out in the claims.

In the accompanying-drawings, Figure 1 is a view in elevation of my improvement. Fig. 2 is a view in vertical longitudinal section of the table, the full lines showing the table in its operative position and the dotted lines showing it tilted, the gage being removed. Fig. 3 is an end view partly in section. Fig. 4 is a view in side elevation of the gage and its supporting-shaft. Fig. 5 is an end view of the latter, the gage-actuating cylinder being shown in section; and Figs. 6 and 7 are detail views showing the manner of mounting the gage-actuating shaft at its end adjacent to the shear.

1 represents. a rectangular table of any approved construction provided throughout its length with a series of rollers2, coupled up so as to rotate in unison and convey any article placed thereonthroughout the length of the table. This table is provided with sides 3, which project above the rolls and prevent any article on the rolls from being discharged over either side, and is supported at its end adjacent to the shear 4 by the arms 5, pivoted at 6 to the under side of the table and secured at their opposite ends to the shaft 7, the latter being supported at its ends in the levers 8, integral with sleeve 9, mounted on shaft 10, the latter being supported at its ends in bearings 11, which latter are preferably formed in projections 12 from the shear-frame or housing 4. Secured to this sleeve 9 in a plane to one side of the table is the lever-arm 13, which normally rests at or about the angle shown in Fig. 2, and which has bearing against the free end of the plunger 14, mounted in the cylinder 15. This cylinder is in an inclined position and is secured to bracket 16, preferably integral with the frame or housing of the shear. From this explanation it will be seen that with a pressure within cylinder 15 in front of the plunger the table will, so far as the mechanism above described is concerned, remain in its elevated position or, rather, in the position shown in full lines in Fig. 2. Cylinder 15 is piped to an accumulator without operating-valves, thus giving constant pressure in said cylinder. When a piece is severed by the shear, the severed end will be forced downwardly by the top knife and knife-holder, and as this severed piece is resting on the rollertable the latter will be forced downward, thus forcing the plunger into the cylinder 15, which displaces an equal volume of water through the connecting-pipe back to the accumulator. When the top knife moves upwardly, the constant hydraulic pressure within cylinder 15 will return the table to its horizontal position. This arrangement makes the upward and downward movement of the table at the shear end perfectly automatic and without the use of operatingvalves.

The outer or discharge end of the table carries the wheels 16, which latter normally rest in the curved seats 17, formed in the sides 18 of the frame 19. These seats 17 are curved to conform to the peripheries of the wheels, so as to normally hold the latter against movement, and thus maintain the table solidly while in its horizontal position.

The sides 18 of the frame constitute trackways on which the wheels 16 travel, and at a point immediately in rear of the curved seats they extend abruptly upwardly and rearwardly and then rearwardly at a gradual incline, so that when the wheels 16 are first forced rearwardly they rise abruptly and then at a gradual ascent rearwardly. Secured to the axle of these wheels 16 or to aww . and 31.

end, as-shownin Fig. 2, -with"the--plungers1 29 1 bearings coincident with the axes of said wheels is the link 20, carrying the pin'21,-to which lathe .crank,arm 22 is ,--secured. 'llhis arm is fixed to the shaft 23, mounted in bearings in the frame 19. Secured to shaft 23 is the lever-arm 25, bifurcated at its lowerxend so as to straddle the cylinder 24. The two ends of the bifurcated end of the arm 25 are pivotally connected at a point intermediate the two cylinders by links 26 with' the

double plunger

29 and 30, mounted in cylinders v24 These cylinders are located end to and 30 moving :i th i spective' cylinders.

"The link 20 1 connecting the lever-arm :22 with "the table, normally inclines upwardly and rearw-ardl-y. 'Hence a lifting pressure applied "thereto tends to elevate. the rearend of'thetable and also causes "the wheels to hug the upwardly and rearwardly inclined tracks on wliich'they-move.

The operation" of the app aratus, at the rear end :thereof -is as 'follows 'With the table in portingthe front end,=-swing rearwardly until they assume the position shown 'in dotted lines, "Fig; 2. 'With the table in'thisinclined pos'ition,-itsfront end or its end adjacent to the shear restsin a=plane below and at \a dis-' tance'removedfrom theshear, thus leaving ample roomf'for thedischarge', of all ends-and other short *sections severed -bythe shear. "To restore-theztable=to its normal=positiom it issimp'ly necessary to exhaust the fluid in' cylinder. 29--andadmitfluid'underpressureto cylinder 31. 'The-pressu-rein cylinder 31 assisted by gravity, causesthe table to assume its fhorizont al 1 position, the -fluid 'in the twin cylinders 24 and 31 causing the parts to move steadily and-without-shoek or j ar.

'-'32'is asha'ft located adj acent to and parallel-with the table. This shaft is p'ivotally "and removably supported at its a front end-in the bearing 33, formed in the housing or shear frame'and is detachably: locked'therein bythe pin 34,-the-rear end: o'fsa'idsha'ft being supported by theframe 35.

Mounted to slide on t-hesha'ft 32 is't-he'gage 36, which latter'is' shaped-asshown and normallvrests over the rolls andEintthe-pathtrav ersed byany :articlerestingi on the rolls. This gage -ca-n"b,e moved to any position and clamped -by anysuit able 1 means and when i in its position 'overthe .rolls forms -a stop -or abutment for one end of the article to be severed by the shear.

Secured'to'the sha'ft 32 at its rear end are the crank-arms 36 to which the pitmen 37 arepivotally connected. These pitmen are connectedat theirrearends to the cross head 38, to which the plunger 39 is secured,

the said across-head traveling in the guidearticle, thelengthof whichhasbeen' gaged by the gage,"has 'b-eensevered by the shear the gage should be turned sidewise sufficiently-to permit the article to pass on and be discharged over the end o'f the table. Again, whendt is necessary-to tilt 'the 'table, as before described, the gage should 'first be thrown overand-to-pne side,'-so as'topermit the tabletoassume its inclinedpositionlwithout interference: from' the gage.

If the gage-arm 36 is placed toward -=-the rear end-"of thetable in position-over: theroll- ,ers, as shown 'in 'Figfi5, and the table be moved 5 to the position-shown Yin dotted lines in Fig. 2, the upward movement of the rear endof the table will automatically raise the gage-arm -36, which movement *will turn sha'ft 32 in1its'be-arings and move the-crosshead 38 andplu-nger -39 outwardwithout the use of-water in cylinder-'41. When the table moves back to itsroriginali'horizontal ;-posi- :tion, the gage-arm 3 6, *being'heavier than its attached 1 parts, will draw the plunger back into cylinder 41. Fromthis it will *be seen that the gage can move automatically with the =movements of the rear end of the table and also *be operated independently by its operating-cylinder 451.

It is evident that :many slight changes might be resortedto in therelative arrangement of parts shown and described without departing "from the spirit and scope 1 of my invention. Hence 'I would have it understood that Ido not'wish to-confine myself:to the I exact I construction and arrangement of partsherein shown and described; but,

I-Ia'ving 'fully described-my:invention,what I claim-as new, and desire to-secure "by #Letters Patent, is
