MEANS FOR GREASING THE NECKS OR JOURNALS OF ROLLING-MILL ROLLS.

SPECIFICATION forming part of Letters Patent 0. 718,471, dated January 13, 1903. I

Application filed August 5 1902. Serial No. 118,496. (No model.)

To all whom, it may concern: 7

Be it known that we, REESE R. JONES and THOMAS W. J ONES, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Means for Greasing the Necks or Journals'of Rolling-Mill Rolls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to means for greasing the necks or journals of rolling-mill rolls; and it consists of the novel construction, com-. bination, and arrangement of parts hereinafter shown, described, and claimed.

The object of our invention is toprovide improved means for automatically greasing side elevation of same with parts broken away.

Fig. 3 is a detail sectional side elevation of the rolls, showing the application of the greasecarrying swabs to the necks of the rolls. It shows the construction from a point of View opposite that of Fig. 2. Fig. 4is a detail sectional view of the grease-pot and the swabchain connections thereto. Fig. 5 is a detail sectional elevation of a portion of the swab chain.

1 indicates a common set of rolls having the usual necks or journals 2, mounted in the ordinary frame 3. Mounted in the space between the necks of the upper and lower rolls 1 is a frame 4, having a plurality of plugs or pins 5 fixed thereto, and mounted upon said pins are a series of small sprocket-wheels 6 and also a flanged roller 7. The two upper sprocket-wheels 6 are mounted in horizontal alinement, so that the swab-carrying chain 8 may run over the same and be drawn for a short distance parallel to the neck 2, and after passing over the said alined sprocketwheels said chain 8 passes downwardly and beneath another sprocket-wheel, which is located closely adjacent the neck of the lower roll, and then said chain passes upwardly and over the flanged roller 7 and thence passes downwardly into the grease-pot 9,

which is preferably located at a point beneath the floor and supported by means of nails or bolts, such as 10, which connect the same to the base or foundation. Mounted upon an arm 11 at a point near the bottom of said grease-pot is a flanged roller 12, around which said chain travels, and the function of which is to cause the said chain to travel near to the bottom of said pot. The arm 11 forms a part of the'extra frame 4 and is connected to the upright bar 13 by means of suitable bolts or rivets 14, and said upright bar is secured to the base by means of suitable bolts or other fastenings. Carried by said chain 8 are series of swabs 15, which are preferably made of some absorptive material, such as a body of flannel or felt, although they may be of any other suitable material, and they are secured to the links of the chain 8 by means of metallic loops 16, which project from the outer face of said chain-links at suitable distances apart.' (See Fig. 5.)

A suitable shield or wiper 17 is secured to the arm 11 immediately above the grease-pot and is curved downwardly at its upper end, so as to be contacted by the swabs 15 as they emerge from the grease-pot, and thereby be relieved from any excess of grease. This wiper may be adj ustably secured in position by means of a suitable bolt or other fastening 18 and is preferably made of sheet metal.

The excess thus removed from the swabs will :of course gravitate into the grease-pot beneath.

We havethus far described our invention as applied only to the necks and one end of the rolls 1; but it is obvious that the same may be duplicated and applied to the opposite end of said rolls or to any number of rolls or sets of rolls.

In some cases we prefer to provide an additional vertical chain 19 and a horizontal endless chain 20, by means of which power may be communicated to the adjacent swab carrying chains of the additional sets of rolls.

21 and 22 indicate the shafts carrying the sprocket-wheels for the said additional chains.

Power is applied to the rolls in the usual manner through the shaft 23, which may be provided with a belt or pulley 24: or any other suitable power-transmitting device.

Power to drive our improved neck-greasing machine is preferably taken from the shaft 23 by means of a suitable chain 25 and is transmitted thereby to the sprocket-wheel having an integral clutch member 26, which parts are mounted to slide loosely upon a counter-shaft 27, which carries the fixed member 28 of said clutch. A suitable hand-lever 29 is pivoted at 30 and engages the loose member 26 of the said clutch, so as to slide the same, together with its integral sprocketwheel, on the said counter-shaft 27 when it is desired to start or stop the greasing-machine. 31 indicates the bearings for the said countor-shaft. Mounted upon the inner end of the said counter-shaft is a bevel gear-wheel 32, which transmits motion to another bevel gear-wheel 33, which is mounted upon a short shaft 84:, extending at right angles to the said counter-shaft and mounted in suitable bearings 35 and which carries sprocket-wheels which impart motion to the swab-chain S and the additional chain 19.

The operation is as follows: The rolls 1 being set in motion by means of power transmitted through the shaft 23, the chain 25 will then cause the counter-shaft 27 to be revolved, and motion will be communicated from the latter through the bevel-wheels 32 to the short shaft 34, and this will cause the swab-chain S to travel over its supporting-wheels, and the swabs 15 will be immersed in the grease containcd in the grease-pot 9 and will absorb a quantity of said grease and carry the same upwardly past the wiper 17, and thence over the alined sprocket-wheels beneath the upper roll-neck 2, and thence downwardly and under the sprocket-wheel just above the neck of the lower roll, and thence over the flanged roller 7, and thence downwardly to the greasepot. The swabs 15 in passing the said rollnecks will automatically supply an ample amount of grease to them.

WVe do not limit ourselves to the exact construction herein shown and described, as it is obvious that the same may be varied within the skill ofamechanic without departing from the scope of our invention.

hat we claim is-- 1. An automatic device constructed with an endless traveling chain carrying absorbent swabs, to take grease from a distant pot and apply the same to the necks or journals of rolling-mill rolls, substantially as specified.

2. The combination with rolling-mill rolls having the usual necks or journals, of a se' ries of chain supporting rollers arranged closely adjacent said rolls, a chain adapted to travel over said rollers, a grease-pot located at a distance from the said necks, means for causing the said chain to run into the said pot, absorbent swabs carried by said chain and arranged to be brought into contact with the said necks, and means for imparting motion to the said chain, substantially as specified.

3. The combination with rolling-mill rolls having the usual necks or journals, of a chain arranged to travel in a line parallel with the axis of the said necks, suitable rollers and wheels for supporting said chain in close proximity to said necks, absorbent swabs carried by said chain, a source of grease to which said chain extends, and means for imparting motion to the said chain, substantially as specified.

4. The combination with rolling-mill rolls having the usual necks or journals, of a chain arranged to travel in a line parallel with the axis of the said necks, suitable rollers and wheels for supporting said chain in close proximity to said necks, absorbent swabs carried by said chain, a source of grease to which said chain extends, means for imparting motion to the said chain, and a wiper for removing excess of grease from said swabs after they leave said source of grease, substantially as specified.

5. The combination with rolling-mill rolls having the usual necks or journals, of a chain arranged to travel in a line parallel with the axis of the said necks, suitable rollers and wheels for supporting said chain in close proximity to said necks, absorbent swabs carried by said chain, a source of grease to which said chain extends, means for imparting motion to the said chain, a wiper for removing excess of grease from said swabs after they leave said source of grease, and means for starting and stopping said chain while the movement of said rolls continues, substantially as specified.

In testimony whereof we affix 011' signatures in presence of two witnesses.
