` INGOT MANIPULATOR.
i -UNITED STATES PATENT OFFICE;
`THOMAS CRITGHLOW, QF PITTSBURG, PENNSYLVANIA.
WiNGoT-MANIPULATOR.
SPECIFICATION forming part of Letters `Patent No. 278,511, dated May 29, .1883.
i Application filed February 23, 1883. (No model.)
To all lwhom tt 'may concern:
Be. it known that I? THOMAS` ORrrcHLow, a subject of Great Britain, residing at Pittsburg, in thecounty ot' Allegheny and VState of Pennsylvania, have invented certain new and useful Improvements in IngotfManipulators,
' of which the following is a specification. reference ,being had therein tothe accompanying drawings.
.This invention relates to improvements in machinery for the manufacture of iron and steel,a'ndit has special-reference to mechanism Vfor operating the ingot during the opera- '1 tion of reducingit to amarketable shape, the
sented to the peripheries of the passes, the` `object being to provide for reducing the cost of manufacture by furnishing a machine which shall perform the Work of a numberof men, and `thereby ed'ect alarge and valuable saving of manual labor.
` It consists in the employment of hydraulic or other cylinders (preferably mounted) located in close proximity to the feeding tables or rolls ofa mill-plant, and in providing such cylinders with means for manipulating or operating -the ingot when in a highly-heated state and while upon the feeding-rolls, either laterally, in order to bring-it opposite to the respective passes in the forming-rolls, or vertically, inorder to` give it apartial rotation around i'ts own axis', whereby its several sides are preseveral peculiarities of which will morefully appear.
l In the accompanying drawings, forminga part of this specification, and on Awhich like hereinafter reference-letters indicate'corresponding features, Figure 1 is a plan view ot' my improved apparatus, and of a train of feeding-rolls having an ingot placed thereon,and showing the rela tive position ot' the 'apparatus to said rolls. Fig. 2 is a longitudinal vertical sectional view takenthrough the center of the apparatus, and axially through one of the feeding-rolls. Fig. 3 represents an end elevation of nthe machine, lookihgfromthe rear thereof; Fig. 4, a side elevation of a train of feeding-rollshaving an ingot placed thereon, showing the relative position of the operating-levers, the 'remainder ofthe machine being in this instance removed; and Fig. 5, a longitudinal sectional viewot' a modified form of cylinder and piston. 1
The letter A indicates a train or series of feedingrolls, the saine being ot' the ordinary or of any approved construction and adapted to be supported and -journaled in the usual framework.
Theletter B indicates a cylinder, constructed of iron or other suitable material, and provided at its forward end with a suitable stuiifing-box,
lateral trunnions or studs orother equivalent devices. Eachof said trunnions is provided with a supporting-wheel, and said wheels are adapted to travel upon a suitable track located in close proximity to the feeding-rolls, hereinbefore referred to. Said cylinder lB is `furnished with a piston-roth'B, having the usual piston-head, which is adapted `to tit therein and to operate in the manner which shall be presently pointed out. ward end is connected, by means of' nulsv or object-'in the present instance with the bedpiece ot the feeding-'train frame-#the purpose ot'lwhich is'to secure the piston against longitudinal movement. At each end the cylinder is supplied with pressurefpi pes b b, for the purpose of introducing and allowing the escape of the steam or other operating agent, the said pipes havingsuitabledevices forcontrclling the induction and eduction otl thepressure agent.
inder B, or other proper support, is a 'vertical cylinder, (indicated by the letter 0,) the same being of ordinary construction and of Vany suitable material, and the upper end of which is provided `with a stutling-box, c. provided with'pressure-pipes c', similar to those .above referred to.
cal cylinder is a piston-head provide-d with a piston-rod, D. Extending laterally from said piston-rod, preferablyv at its upper end, project trunnions or lugs d. -Flexibly connected to and depending from said trunnions are conconnecting-rods being suitably bored, and provided with bolts and nuts, or other equivalent devices, by which the connection is eii'ected.
tending from the forward end ofthe cylinder B are somewhat longer than those from the rear of the said cylinder, andare adapted to Said piston-rod at its for-l otherwise, with a suitable fixed or stationary.
`At a suitable point, and located upon said cyl- It is also.
Fitting within said verti' fleeting-rods E, 'the ends of which are also iiexibly connected to the shorter arms of the manipulating-levers F, the said levers and" The trunnions hereinbefore mentioned as exand on` its opposite sides, at both ends, with 6c roo act as fulcrums for the manipulating-levers, which are suitably bored and tted thereon, as indicated in Fig. 1 of the drawings. .The longer arms of said manipulating-levers extend between the feeding-rolls A, and are formed or provided with vertical extensions F, the termini of which are preferablyshouldered, or otherwise provided with means for engaging the under side of the ingot, as hereinafter pointed out. These levers are preferably braced together at one or more points, as indicated, by means of a connecting-bolt, f, or other equivalentdevice.
. The operation of my invention will be readily understood when taken in connection with the above, and is as follows: In order to move the ingotlaterallyon the rolls and bring it opposite the several passes, the controlling-cocks o`r pressure-regulating devices are properly adjusted and hydraulic or other pressure is admitted to the cylinder B, which causes the same to approach or recede from the feedingrolls, (its piston being fiXed,) traveling as it does so upon its supporting-wheels, and pushing'before it. or carrying with it the manipulating-levers F, the extensions of which engage with the ingot from either side; and in order to tip or rotate the ingot the pressurepipes 'of the vertical cylinder C are properly adjusted to admit pressure of the character above alluded to, whereby its piston is operated, and through the medium of the connecting-rods F oscillation is imparted to the manipulating-levers about their fulcrums, their longerv arms engaging with the lower side of the ingot, and during a vertical or approximately vertical movement effect its rotation or turning.
It is obvious that the cylinder B may in some instances be provided with other supporting appliances than those shown-such as slides-and that the other several detail features of my invention may be modified, both .as to formand relative arrangement, without departing from the spirit of my invention, among which modifications are the cylinder and hollow'piston shown in Fig. 5 of the drawings, the object of which is to avoid the use of flexiblepipe-conneetions, which is necessary to compensate for the movement of the cylin-v ders. In said figure the hollow piston is extended-beyond the pistou-head in both direcv tions, and is'provided ou either side of the head with port-holes. Either end of the piston is xed or anchored-in the present instance that end nearer the feeding-rolls-tbe said end being provided with screw-threads and binding-nuts, by which it is secured to the anchor-bracket. Fitting snugly within or over (preferably the former) each end of this hollow piston are pressure-pipes, which serve to conduct the pressure agentto the cylinder through the medium of the said piston. The cylinder may be provided with suitable exhaust or dischargev cocks or valves.
Having described my invention, what Iclaim 1. In machinery for the manufacture of iron and steel, the combination, with the feedingrolls, of a traveling cylinder provided with a fixed piston-rod and manipulating-levers, and means for operating the same, whereby the ingot is shifted upon the rolls, substantially as shown and described.
2. In machinery for the manufacture of iron and steel, the combination, with the feedingrolls, of one or more traveling cylinders proor manipulation ot' the ingot is effected, substantially as and for the purpose specified.
, 4. In machinery for the manufacture ot' iron and steel, the combination, with the feedingrolls, of a traveling. cylinder provided with a movable piston. and manipulating-levers, and means for` operating the same., whereby the ingot is turned upon the rolls, substantially as shown and described.
5. Ina machine for manipulating ingots during the process of marketable reduction, a traveling reciprocating cylinder having a fixed piston and pivoted manipulating-levers,
in `combination with a cylinder having a movable piston connecting with said levers, whereby the latter are given a compound movement for the purpose set forth.
6. In a machine for manipulating ingots during the process of marketable reduction, a traveling reciprocating cylinder providedwith a hollow txed piston-rod having suitable porty holes and pressureagent-conducting pipes, substantially as described and shown.
