Application filed October 25,, 1924. Serial No. 745,848.

. My invention relates to paper ruling. 1na

chinesand particularly to meansfor auto matically controlling the. drier means so that the blanket shall not be injured thereby when the machine is stopped forany purpose Heretofore, .in the operation of paper ruling machine, Whenever the machine is stopped and the blanket" brought to rest, it is nece s ry for the. operator to cut off the drying, heater as otherwise the blanket 're-. maining stationary above the heater would be" damaged or" burned. The operators are often, careless in cutting off the heatersand theresultii's that theblankets, whichare very expensive, are frequentlydamaged.

Iha've conceived that automatic means mayf'be' provided vvhich will either cut out the drying heater or (reduce its temperature,

Whenever the blanket is stopped so that the;

blanket, though stationary aboveit, would not be injured thereby;

More particularly, the. object of my invention is to connect a control mec hanism forthe heater with the start and stop mechanism of the' rulingimachine in such manner that the stopping of "the machine will cut of? I the heater.,

My invention further comprises the noyel details of construction ancl ari'-angements of parts, WhlGll 1n their preferredembodiment Q only are illustrated in the; accompanying.

I have illustratedmy invention as applied to a pap erfruling machinewhichmay be of any suitable type that shownbeing a conventional ruling machine which comprises a main framework havin uprightsl and 2 Which support horizontal frame members 3 and 4. On the uprights 2 is a feed table 5 and the upper ends of these uprights project Well above the frame and carry underhung arms 6 in which a roller 7 is journaled. The

frame members 4: support standards 8 having a roller? journaled at their top and a roller l0 journaledat their bottom. Strings pass around. these several rollers9 and. 10 and over the se ni'ent'board 12 to a roller 13 near the feedtable 5. ,This arrangement is of convent onal design andv forms no particular part of my invention. The roller 13 is driven by a gear 14 meshing a gear lasuitablyiefi mounted in the? frame and driven by a slid ing clutch gear lbfhaving fast and loose members which are driven from any suitable 'source ofpower and by any available transmission, this being, conventionally illustrated by, a pulley driven ,gear 17. The sliding olutch'gear 16 is controlled by a clutch arm 18 having a clutch engaging yoke at its lower end and haying its upper end connected to a collar 19 fast on the clutch throw rod 20. Theclutch arm 18 is mounted to rock on a bracket 21'fast on an upright 2. I provide a second bracket 22 on said upright and pivot thereonintermediate its ends a lever 23 disposed for hor zontal movement and having one end connectedby a link 24 with a clamp sleeve 25 applied rigidly to the clutch rod '20. 'lheother.end of the lever 23 carries a pin 26 working in an elongated slot 27 in a T-shapednrockerjarm 28,-the ends of theT- head of said arm being connected by chains, ires orother suitable connectors 29 and 30 With a rocker 31 made fastat its center to the 'stein32' ofthe gas supply valve 33 in the valvebody 34E. This valve 33 is an ordinary oneay valve for controll ng the deliveryof "gas through the Bunsen tube to a burner 36, there being a. p lot; burner 37 connected I the gas supply ahead of the byla tube 38 with valve 33.

The nianner in which the rocker elements 31and28 are connectedcauses them to be rotat-ed together andthe arrangement of parts is J such that when the clutch rod 20 is shifted to throw out the clutch the valve will be turned to shut off the supply of gas to the burner 36. The burner 86 delivers its products ofv combustion through a cone 39 to a perforatedtube havingany desired number of in As shown, this blanket passes between the roller 43, driven by the gear 15, and the roller 13 driven by the gear 14 and hence passes about a roller 44 at the left hand end of the machine and then downwardly and about the roller 45 at the right hand end of the machine, and then rearwardly under the heater coils 40 around a roller 46 on a v0:- tical frame member 47, and hence about a roller 48 in the standards 2 and upwardly about a roller 49 and back to the roller 43. Rollers 50 and 51,, mounted in uprights 4'? and 52, support the flight of the blanket about the heater coils 40.

In operation, assuming the clutch thrown to couple the drive for the blanket, the lat ter will be continuously driven as will also the strings 11 and the gas burner will be turned on full flame. W'henever, for any reason, it is desired to stop the machine, the clutch rod is shifted in the opposite direction and this motion acts sin'iultaneously both to intercept the drive to the blanket feed rolls and to turn off the supply valve to the gas burner, thus cutting of? the drier burner and keeping it off until the clutch rod is again thrown to start the blanket drive when the valve is again turned on full and the gas, being ignited by the pilot fl e, will again supply the heat to the coils J). By this arrangement, the heater cannot be left going while the blanket is at rest and thus the blanket is at all times automatica ly protected against damage from the drier heater.

It is to be understood that the sheets of paper which are fed onto the blanket between the rolls l3 and 43, pass on top of the blankets under the ruling appliances and then are carried along under the blankets by means of endless strings 53 which pass from an upper roller 54 onto the blanket and follow it about the rollers 44 and 45 to the roller and thence pass over the roller 56 and around roller 57 and return to the roller 54. They thus hold the sheets face down in passing over and face up in passing .under the heating coils 40 and the heat in these coils will serveto dry the ruling on the paper sheets, the latter being discharged at the roll 46 to a lay-boy not shown.

It is to be understood that the heater shown is typical of any available heater and that the operation of the rocker 31 may cut off the heat entirely or lower it to a safety point where it will not damage the blankets. I claim broadly the idea of providing means which will respond automatically to the starting and stopping of the blanket drive to interceptheat from the drier in such manner or to such extent as will prevent damaging the blanket.

Though I have described with great particularity the details of the embodiment of the invention herein shown, it is not to be construed that I am limited thereto, as changes in arrangement and substitution of equivalent; may lJG made by those skilled in the art without departing from the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a paper ruling machine having a blanket, a drive therefor and a drying heater hav a closed pipe coil for the rodnets of com stion passing between ights of the blanket, means to interrupt the drive to the blanket, and means automatically re- SpODSiVG to the interruption of the blanket drive to cut off the heater.

2. In a paper ruling machine having a blanket, a clutch controlled drive therefor, a drying heater having a clove-d pipe coil for the products of combustion passing between flights of the blanket, and connected elements to cut off the heater sin'iultaneously with the throwing out of the clutch.

3. A paper ruling machine according to claim 2, in which the connected element will automatically restart the heater when the clutch is thrown in.

4. In a paper ruling machine, a blanket and a drive therefor having a clutch control, a drying heater con'iprising a gas burner remote from the blanketwith a main control valve and a pilot burner, mechanical connections between the gas cont-r01 valve and V the clutch control adapted to close the valve when the clutch is opened and to open the valve when the clutch is closed, and a pipe coil. forn'iing' part of the flue for the products of combustion from the heater, which coil interposed transversely of the machine between flights of the blanket.

5. In a paper ruling machine, a clutch con trolled drive for the blanket of the machine, a drier burner havinga heating coil interposed between flights of the blanket, a valve for said burner, a clutch operating rod, a rocker operably connected to and reversely movable by said clutch rod, and connections to transmitboth rocker movements to open or close the valve, and a pilot burner for theheater.

6. A paper ruling machine according to claim 5, in which the rocker is of T-type with its connections to the burner valve formed by flexible wire cables.

In testimony whereof I afiix my signature.

MAX F. OESER.
