REVERSING ROLLING-MILL.
SPECIFICATION forming part of Letters Patent No. 669,242, dated March 5, 1901. Application led October 22, 1900. Serial No. 33,965.. LNo model.)
To all whom, it may concern.-
Be it known that I, JOHN G. HoDesoN, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Reversing Rolling Mills, of which the following is a specification.
This invention relates to reversing rollingmills for rolling metal bars, sheets, or packs of sheets.
The object of this invention is to provide a reversing metal sheet, plate, or bar rolling mill of a strong, simple, elicient, and durable construction, by means of which metal bars, plates, sheets, or packs of sheets may be rapidly and successively passed back `and forth between the rolls and in which the feed-screws, by which the rolls are set or adjusted closer together as the rolling proceeds, maybe operated either by hand or automatically at each reversal of the mill and by diminishing iucrements after each successive pass, as may be required, and by means of which the feedscrews may at the same time be positively and accurately adjusted and rigidly and unyieldingly held in adjustment.
The invention consists in the means or mechanism employed for practically accomplishing this object or result-that is to say, it comprises in a reversing rolling-mill in cooperative combination with the reversingrolls friction-clutches and a hydraulic ram for operating the same to reverse the rolls, a reversing valve and valve-lever for said ram, feed-screws for setting or adjusting the rolls closer and closer together, as required, worms and worm-gears for turning the feed-screws by hand, a rack and gears for turning or adjusting the feed-screws automatically, a hydraulic cylinder and piston for operating the rack, a starting-valve t'or said feedscrewop erating ram operated by a low or city-water pressure cylinder and piston connected to the reversing valve-lever, a stopping-valve for said feed-screw ram automatically operated by a notched register or controlling bar connected to the piston of said ram, the notches in which register or controlling bar are differently spaced to give the required or diminishing increments of motion to the t`eedscrews at successive passes, the feed-screw ram having also two further valves for returning its piston and the feed-screw rack and notched bar connected thereto to position by a single continuous movement after each complete rolling operation.
The invention also consists in the novel construction of parts and devices and in the novel combination of parts and devices herein shown and described, and specied in the claims.
In the accompanying drawings, forming a part of this specification, Figure l is a front elevation of a reversing rolling-mill embodying my invention, and Fig. 2 is a detail planv showing in diagram the valve and hydraulic pipe system. In these views the reversing feed-tables which are geared or connected to the driven roll by any suitable gearing or connecting mechanism, so as to be reversed with the rolls, are omitted for sake of clearness of illustration. Fig. 3 is an enlarged-detail plan view of the valvetable,`and Fig. 4 a side elevation of the same.
In the drawings, 8 represents the frame of the machine or mill; 9, the upper roll; lO, the lower or driven roll; ll, its shaft; l2 and 13, friction-clutches for reversing the rotation of the rolls through any suitable gearing or mechanism; 14 and l5, the hydraulic ram which operates the friction-clutches alternately through the connecting-lever 16.
17 is the reversing-valve, connected by the pipes 1S 19 with the clutch-ram I5, and 20 is t-he friction-clutch valve-lever, by movement ot' which lever the operator reverses the rota tion of the rolls as required.
The stopping-valve 31 of the feed-screw ram 28 has a valve-lever 43, furnished with a roller 44 and a weight 45, and is operated by a notched register or controlling bar 46,Which 'is secured to the piston-stem 27 of the t'eedscrew ram, so as to he reciprocated thereby. The notches 47 in the register or controlling bar 46 are at varying distances apart, being closer together at the right-hand end ofthe bar titan at the left-hand end thereof, so that the feed-screw-operating rack 26 will be moved bydintinishing increments at each successive reversal of the rolls as the rolling proceeds. The notched controlling-bar 46 is removably connected to the piston-stem 27 or rack 26 by a pin 4S, so that by simply removing one notched bar and replacing it with another having its notches differently spaced any required degree or extent of movement may be automatically given to the feed-screws as may be required.
'lhe feed-screw ram 23 has a combined feed and exhaust or two-Way valve 49, connected by a pipe 50 with its forward or right-- hand end, and a feed-valve 5l, connected by a pipe 52 with the rear or left-hand end of the feed-screw ram 28. The operating-levers 53 54 of the valves 49 5l are connected together by a link 55, so that they are operated simultaneously.
56 is the city or low-pressure water pipe leading to the valve 40 of the low-pressure cylinder 39, by which the starting-valve is operated, and 57 is the pipe leading` to the accumulator or hydraulic pump, from which water under pressure is supplied to the hydraulic rams as required through their operating-valves.
The operation is as follows: When the detachable link 42, connecting the reversing valve-lever 2O and the lever 4l, through which the starting-val ve of the feed-screw ram is operated, is disconnected, the mill is reversed by the operator moving the reversing-lever 20, which releases one friction-clutch and operates the other through the clutch-rain l5. \Vhen thus operated, the feed-screws remain unchanged or unmoved through successive passes and are turned or adjusted as may be required by hand through the worms and worm-gears- 23 24. When, on the other hand, the levers 20 and 4l are connected together by the detachable link 42, the low-pressure-cylinder valve 40 is operated, thus causing the starting-valve 2l) to be momentarily openetlthat is to say, while the cam o1' projection 35 is passing under the roller 3601i the startingvalve lever 33, the starting-valve lever being closed very soon after it is opened. During the short interval the startingvalve 29 is open the wateror other liquid under pressure may flow ont from the rear or left-hand end of the feed screw ram cylinder 28 through the relief-pipe 30, which connects with the waste or discharge pipe through the starting-valve 29, and the two-way valve 49 being in its normal position, as illustrated in Fig. 3, the water under pressure Hows through the pipe 50 into the forward or right-hand end of the ram 2H, thus moving its piston to the left and cansing the roller 44 to ride out of the notch 47 in the register or controller bar 46, and thus to open the stopping-valve 3l, so that the water may now escape from the rear end of the ram 2S through the Waste-pipe 32 until the stopping-valve 3l is again closed, which is automatically done the moment the bar 46 is moved far enough to permit the roller 44 to drop into the next notch, as the controllerbar 4G only holds the stopping-valve 3l open for the space between the notches. The moment the stopping-valve is thus closed the feed-screw ram 2S can give no further movement to the rack 26, because the water cannot escape from the rear end ot' the cylinder, the starting-valve 29 having been previously closed, as before stated. When it is desired to turn up the feed-Screws by withdrawing the rack 26 to the right to its lirst position, this is done by swinging the levers 53 54 into the reverse position from that indicated in Fig. 3, thus causing the water under pressure to feed into the left-hand end of the rain 28 through the pipe 52 and flow out from the right-hand end thereof through the pipe 50, which the two-way valve 49 now connects with the discharge or waste and disconnects fromthe Water feed or supply pipe leading from the accumulator' or hydraulic pum p or other source of liquid under pressure. If the operator wishes to turn the rolls down several or all of the notches of the register or controlling bar 46 at once or by one continuons movement to the left, this he may do by simply lifting the weight or holding up the lever of the starting-valve 3l, thus keeping the relief or IIO discharge through the starting-valve open until the feed-screws are turned down to the extent desired.
