SPECIFICATION forming part of Letters Patent No. 437,540, dated September 30, 1890.

Application filed July 5, 1890. Serial No. 357,802- (No model.)

.To all whom it may concern.-

, Be it known that I, SERN PERLEY WATT, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Rolls; and I do 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 has relation to pyramid rolls for shaping shells or plates; and it consists in the construction and novel arrangement of parts, as hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

The objects of my invention are, first, to so construct the machine that the half-bearing blocks for the lower rolls may belaterally adjusted with reference to the longitudinal center of the bending-roll; secondly, to so construct the caps forming top bearings of the lower rollsand guides for the removably-secured heads on the bending-roll that they may be disconnected at their upper edges and swung back out of the way when it is desired to remove the heads on the bending-roll journals after a plate or shellhasbeen rolled thirdly, to provide a simple means for adjusting the bending:roll vertically when it is desired to remove a plate or shell; fourthly, to so construct the adjusting mechanism of the bending-roll that either end of said roll ma'y'be vertically adjusted when itis desired to form a conical or tapering shell; fifthly, to provide the main frame with castings removably secured therein by through-bolts having bearings in which are j ournaled the shafts of the adjusting mechanism, whereby said shafts may be easily and readily lined up.

In the drawings, Figure 1 is a perspective view of a set of pyramid rolls embodying my improvements; Fig. 2, a similar view showing the caps uncoupled and the double-socketed head in position on one of the journals of the bending-roll; Fig. 3, an end view of one of the frames, showing caps in place, also the bending-roll; Fig. 4, a plan view of the caps; Fig. 5, an end View of one of the frames, partly in section, showing the adj usting-shaft,

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, the letter A indicates the base of the machine, of ageneral rectangular form, and has secured in any desired manner upon its upper face near the ends thereof suitable bearing-frames A, re cessed, as shown at a, and adapted to receive and support the half-bearing blocks a, said bearing-blocks being somewhat shorter than the length of the recesses and adapted to be laterally adjusted in said recesses by setscrews a passing through the sides of the frames and having their inner ends bearing against the sides a of the half-bearing blocks, as shown.

B and B designate rolls provided with journals B adapted to rest and work in the halfbearings a.

B designates the bending-roll, provided at eachend with journals 1), adaptedto receive the removable heads I), said heads being providedbgvith downwardly-proj ccting perforated ears their inner ends in suitable bearings 0, formed on the base of the machine.

To allow of the shafts to be readily adjusted and kept in line,

the frames are cut away, as at C and have secured therein by means of bolts suitable castings 0 provided with laterally-cxtendin g horizontal arms 0, having at their outer ends the half-bearings 0 in which are secured by means of caps c the outer ends of the shafts O and O. Loosely mounted upon said shafts at their meeting ends is a gear-wheel D, the hub of which is provided upon its inner face with a pin m, extending from side to side thereof-between" the meeting ends of said shafts, as shown in Fig. '7, and prevents lateral play of said wheel upon the shafts. On opposite sides of the hub are formed clutches D, consisting of the laterally-extendin g pins cl, preferably fourin number, and are adapted to alternately engage or disengage the pins d of the movable clutches D said clutches being similarin form to the clutches D and are splined upon the shafts O and O and dc signed to have a longitudinal movement I thereon by means of suitable spring-controlled levers to the front of the machine, as hereinafter explained. Near their outer ends and between the arms 0 of the castings O the shafts C C have rigidly mounted upon them worms E, which mesh with like wheels E, located at the bottom of the frames A.

F'designates a gear-wheel rigidly secured .to the inner end of a shaft F, journaled in suitable bearings formed on the base of the machine, and is provided at its outer end with apinion having a suitable connection with the main driving-shaft, and is designed to im- .part motion to the shafts C 0 through the gear-wheel D, as will hereinafter appear.

Loosely pivoted at their upper ends between the perforated cars 19 of the heads I) by bolts n are the vertical adjusting-shafts G, which passdownward through an opening g in the .halfbcarin g blocks and have their lower ends screw-threaded, as at g and pass through like openings gin the worm-wheels E, and, as will be noticed, said adj ustin'g-shafts further serve as shafts for the worm-wheels'E"in the lower part of the frames A. Below the end of the shaft G in the frames A are openings in which are secured by means of a set-screw g Upon the upper edges of the heads are secured thereto in any desired mannerbushings g their lower edges passing below the bottom of the frames and serve as guards for the screw-threaded ends of the shafts G when in their lowered position.

In order that the bending-roll may be adj usted by the shaft G, and to prevent the binding of the heads upon the bending-roll journals or thebinding of the worms or shafts, I form the heads I) with their rear faces 0' inclined upwardly and outwardly, as shown.

H designates caps provided at their lower outer edges with perforated lugs h, between which fit perforated lugs h on the upper edges of the frames A. Said caps are further provided upon their upper ends with vertical transverse kerfs 71 in which are designed to fit a coupling-bar 7L which locks said caps together when in a closed position, as shown in Figs. 1, 3, and 8. Upon the inner vertical faces 72/1 of the caps H is formed a vertical recess h designed to receive the projectingends of the coupling-pins n and prevent the same from working out by accident.

The rolls B B upon one end are provided with gear-wheels I, which are suitably connected by means of intermediate pinions and gear-wheels to the main driving-shaft, whereby motion is imparted to said rolls.

Pivoted by means of pivot-pins e c on a latcrally-extendingarm I on the main frame are the spring-controlled levers it, provided at their inner ends with the upwardly-projecting forked portion i designed to fit in a suitable groove or recess f formed in the clutches D The letters i 2' indicate levers pivoted at one end by means of pivot-pins f to the outer ends of the levers it, their opposite ends pivoted to the lower ends of suitable operatinghandles J J by pivot-pins f said operatinghandles being fulcrumcd near their inner ends to the main frame by pivots ff. After a shell has been rolled or formed and it is desired to remove the same from around the tween the perforated ears b of the head I).

Said head is then removed from the journal Z; by means of a suitable connection with a derrick and a double-socketed head K placed upon the journal I), and a bark inserted in the outer socket 70, designed to raise the roll and receive the shell when it is slid from the bending-roll, when it may be removed to any desired place. The head K is then removed and the head. 6 replaced and the caps H locked in position, as shown in Fig. 1.

To raise or lower the bending-roll at both ends to accommodate plates of different thicknesses or to adjust one end vertically when it is desired to-form a conical or tapering shell, proceed as follows: Power-is applied andthc machine put in motion, which causes the gear- Whecl F to revolve, and with it the gear-wheel 'D, andby forcing the operating-levers J and J together at their outer ends, as indicated by the arrows, the clutches D through the media of the levers t' 77 and t 2", will move laterally upon the shafts O and U and enjusting-shaft-s G, cause the bending-roll to be raised or lowered at will.

It will be readily seen that, owing to the in dependent connection of each of the adjust ing-shafts, either end of the bending-roll may be raised orlowered when it is desired toform a tapering shell.

I do-not desire to confine myself to the precise construction herein shown and described, as many changes may be .made without departing from the spirit of my invention.
