SPECIFICATION forming part of Letters Patent No. 426,046, dated April 22, 1890.
Application filed November 23, 1889- $e1ia1 No. 331,296. (No model.)
To all 1071/0712 it may concern:
Be it known that we, GEORGE F. MCCLEANE, of Allegheny, and \VILLIAM M. FABER, Jr., of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Mill Appliances, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in Wl1lCl1- Figure 1 is a plan view of our improved crane and metal-supporting device or grippers. Fig. 2 is a side elevation thereof, the lower part of the mast of the crane being shownin vertical section. Fig. 3 is an enlarged vertical section of the lower part of the craneinast, including the cylinder and plunger, and showing the valves in side elevation. at is a similar view of the top of the mast. Fig. 5 is a side elevation of the outer part of the jib and the metal-supporting device or grippers. Fig. 6 is a vertical section on the line VI VI of Fig. 5. Figs. 7 and 8 are plan views of the metal-supporting device or grippers, showing the jaws open and closed, respectively. Fig. 9 is an enlarged perspective view thereof, showing it in the act of gripping and supporting a metal piece or pile.
Like symbols of reference indicate like parts in each.
The parts of the apparatus shown in the drawings to which our invention relates are the following: first, the arrangement of the Water-connections at the base of the mast of the crane; second, the grippers or metal-supporting device; third, the manner of its support from the jib and the means by which the thrust occasioned by the gravity of its burden is taken up by the jib, and, fourth, the arrangement and location of the cylinder by which the buggy of the peel is moved on the ib. J The purpose to which we have especially designed our improvement is for use as means for charging metal piles or pieces into heating-furnaces and withdrawing them there from, and we shall so describe it, promising, however, that the invention is not limited thereto, but is intended to cover generally the use of the apparatus for any purpose to which it may be applicable.
Referring now to the drawings, 2 represents the mast of the crane, which is or maybe composed of metah beams secured at their upper ends to a block or casting 3, which forms the top journal, and at thebasc secured to the usual upright cylinder i and t0 the lock or casting 5, which forms the bottom journal. The contracted portion or journal proper at the end of the casting 5 has bearings in a plate 6 and in the base of a box 7 within which said plate is set, the weight of the crane being supported by anti-friction rollers S, interposed between the bottom of the casting and the surface of the plate. These rollers are preferably conical in form, and the opposing faces of the casting and plate are correspondingly beveled. The mast is rotated by means of a rack 36, which is moved longitudinally by the plunger of an hydraulic cylinder 37, and which meshes with the teeth of a spur-wheel 37, fixed to the j ournal-block 5. This cylinder is controlled by a valve 38, which is connected with an accumulator or pump 39, and is also connected by branch pipes 40 with the ends of the cylinder.
The base of the cylinder a is somewhat separated vertically from the surface of the bottom journal, so as to afford an intermediate space to permit easy adjustment and coupling of the water-pipes. One of these pipes 9 (the supply-pipe) extends vertically from a stuiiing-box 10 beneath the bottom journal, through said journal, and thence to the valves 11 12 13, which are supported on a suitable platform 14, attached to the mast. The exhaust-pipe 19 extends from a stuffingbox 18 in the top journal of the mast, and is connected by a passage leading through the journal-block to a pipe 19', which by suitable branched connections communicates with the exhaust-ports of said valves. From the valve 11 a pipe 11 leads to the base of the cylinder.
15 is the plunger of the cylinder, and 16 is the crane-jib, which is atlixed to a block 17 at the top of the plunger, so that it shall be moved vertically with the latter. The jib is steadied in its vertical motions by a stru't 20 and suitably arranged wheels 21, hearing against the beams which form the cranemast.
a supporting device or peel.
22 is the trolley which upholds the metal- It is mounted on wheels, on the beams of which the jib is constituted, and is connected by a rod 23 with the plunger of a hydraulic cylinder 24. The
jib extends to both sides of the mast, the trolley being on one side and the cylinder on the other, so that the weight of the latter shall serve partially to counterbalance the jib. Water-supply pipes 25 extend from the valve 13 to both ends of the cylinder 24, and are provided with jointed or flexible connections 26, to permit the variations in distance between the cylinder and the valve caused by the vertical motions of the jib. By proper operations of the valve 13 water may be admitted to either end of the cylinder 24 and the plunger and trolley moved longitudinally on the jib in either direction. The stirrup or buggy by which the grippers or metal-support is upheld consists of metal frames or plates 27, which extend vertically from the trolley between the beams of the jib, and are connected at the lower ends. A bar 28 is carried by and bolted to the stirrup 'thus formed, at the front end projecting considerably beyond the stirrup and at the rear extending upwardly to the jib, and being provided with an anti-friction roller or wheel 29, which bears against the under side of the latter.
30 80 are the jaws of the tongs which form the grippers or metal-support. These jaws are formed with horizontal portions pivoted at 31 to the bar 28, and with vertical portions b, which extend downwardly at the sides of the bar, and at their lower ends are provided with inwardly-turned lips c. The rear ends of the jaws 30 are connected by knee-levers 32 to a rod 33, which is fixed to the plunger of a hydraulic cylinder 34,thelatterbeing mounted on the bar 28 between the stirrups 27, and
"being connected by jointed or flexible pipes 351p the valve 12, so that by proper operation'of the valve the said rod may be proj ected or retracted and the partsb of the jaws 30 caused to approach or to diverge.
The general operation of the device in charging and withdrawing metal is similar to that of the charging-cranes now employed. In the use of the apparatus the grippers or metal-support may be introduced into the door of a furnace by turning the crane-mast so as to direct the crane-jib toward the furnace and then projecting the buggy and peel by means of the cylinder 24.
To "ras a I a D port to the metal, and thus enables the device to be used in lifting metal piles composed of a number of pieces loosely bound together without danger of disarranging or separating them. If the jaws should not grasp the metal exactly at the middle, the metal will be restrained by the top bar 28 from tipping and upsetting. .The action of the apparatus in this regard is shown in Fig. 9, in which the metal piece is grasped on a line off the middle. Then the metal is thus grasped, it may be lifted by raising the jib of the crane, and then conveyed to any place within the sweep of the crane by turning the latter or moving the trolley along the jib. When carried to the proper place, the piece is released by reversing the cylinder 34, and thus opening the gripper-jaws. For the purpose of enabling the grippers to operate successfully in'lifting metal from or depositing it on the usual inclined hearth of a heating-furnace, we prefer to make the bar 28 somewhat downwardly-inclined, as shown in the drawings. hen the metal is supported, the position of the weight at the end of the bar 28 will tend to tip the buggy and trolley; but the bearin g of the bar on the under side of the jib takes up the thrust thus occasioned and prevents the parts from tipping, while the wheel at the end of the bar prevents the friction on the jib from impeding the longitudinal travel of the trolley and buggy.
The advantages of our invention will be ap-' preciated by those skilled in the art construction of the parts may be varied in divers ways without departing from the invention as covered in the following claims, each one of which relates to a distinct item of the invention, covering parts which may be used in other combinations. For example, the grippers claimed herein may be used on cranes or charging apparatus of diiferent pattern, and the other parts of the apparatus to which claim is made may be used with grippers or supporting devices of quite different construction from that herein described.
We claim- 1. The combination, with the jib, of a travelin g buggy upheld thereby, a supporting device at one end thereof, and a brace or bar at the other end having a bearing against the under side of the jib, substantially as and for the purposes described.
2.
