This invention relates to drafting of locomotives in roundhouses during the firing up period, but it is capable of general use particularly certain parts of it.

The principal objects of the invention are to eliminate the usual steam pipe with which roundhouses are now provided; to substitute for it electrical mechanism which will be shut off automatically when the blowers are removed,

This method is with a preferred embodiment of this invention very costly and cumbersome. The advantages shown connected therewith; of a blower system are fully appreciated, but 55 heretofore blower systems have always been of a stationary nature, the stack being connected by flexible or telescoping pipes to the blower intake. The blower then discharges the gases of combustion, or the air induced, through a chimney. This system has been found very costly to maintain, cumbersome in operation, and tending to a waste of power on account of the tendency of the operator to leave the blower intakesopen, thereby using needlessly much power.

With my system I provide a small motor driven blower which takes care of one locomotive at a time, but may be used in any of the several stalls of the roundhouse. A number of such blowers may be used side by side or widely scattered over the roundhouse thereby giving the utmost flexibility of operation. For this purpose I provide a monorail supporting system substantially paralleling the roundhouse wall and having spurs leading to each stall of the roundhouse, these spurs being connected to the main rail by twoway switches. Instead of using a monorail with spurs eachstall or drafting space may, of course, be provided individually with an independent rail or. track.

.In Fig. 1.I have shown part of a roundhouse whose wall I I I is paralleled by a monorail system.

, The roundhouse has a number of stalls I I2 each with a smoke jack 3 as usual. I-beams II I constitute the main rail parallel to the wall and there are a series 3 of spurs I I5 and two-way switches or pivoted track sections IIB of usual construction. These switches are each operated by two chains hanging down. Each spur runs outside the smoke jack out of the path of the gases which rise from the smoke stack when the engine is put under it. This adds to the durability of the rails as they are not in the direct path of the corrosive gases.

Each spur I I has brackets 58 which support an electric switch box 58. The wires 60 (Fig. 3) of each blowers driving motor end in contactors 6| which engage with flat conductors 53 of the switch box 58. By means of a chain 62 operating a sprocket connected with gearing 67 a geared trolley 55 supporting each blower is moved along the track, carrying the blower with it. To allow it to pass around the curve and through the twoway switch the frame of the trolley is loosely fitted on the opposite flanges of the I-beam. This play may prevent the contactors 6| from engaging properly with theconductors 63. To take this play away the I-beam is provided with a filler I I8 Withinthe operating zone so that the opposite converging wheels 8 of the trolley 55 have no side play This filler 8 has a slant I20 at the entrance point so as to facilitate the proper placing of the trolley.

' The blower 50 is carried by trunnions 52 on a fork 5| counterweighted at 51 and supported on a swivel joint 53 by a chain 54 from the trolley 55 so that the blower can be raised and lowered. Chains 56 limit the downward travel of the blower about the pivot, the blower being slightly heavier than the counterweight 57. As soon as the contactors 8| disengage from the conductors 63 the motor stops. Therefore, the blower will always be inoperation when it is within the normal operating zone, that is, anywhere below the smoke jack, the reason for which will be explained later.

By pulling straight downward on a chain 65 the blower will be raised, and by letting this chain go the blower will be lowered thus taking care of different heights of stacks. By pulling on the chain sideways the blower will describe the are of a circle, pivoting about the supporting chain 54, thereby allowing the blower to take up any position within this arc and lowering it on the smoke stack of the locomotive whether this is located right in the center of the smoke jack or on either side of it.

Through the arms of the supporting fork 5| (Fig. extends the pivot bolt 68 with a bushing 68 on which is mounted the inner race of a selfaligning bearing 10. The outer race of this bearing is located in a housing II covered by an enclosure I2. The housing II has a vertical eyebolt I3 to which is fastened the supporting chain 54 so that there is a slight oscillating motion around point I4 in the center of the fork 5|. It is necessary that this motion be about this point to enable the relative proportions in the weights of the blower and the counterweight to be maintained. This motion is sufficient to take care of any dis-alignment of the stack so that the blower will rest. snugly on the stack, in substantially centered relation thereto, by means of the flared intake at the lower end of the blower casing 50; this occurs regardless ofthe stacks position even if the locomotive is tilted materially out of its normal upright position.

The blower casing 50 (Fig. 7) is formed in two pieces, to the upper of which is bolted a spider 8|, the hub 82 of which forms the upper end cap and bearing housing of the motor. This end cap has cored slots 83 and an end shield 84 which forms with the hub- 82 a continuation of the cored slots 83. Leading to the cored slots 83 is an annular air chamber 85 formed by the motor housing 86 and motor cover 81 enclosing the entire motor. To this air chamber 85 lead one or more radial pipes 88 from the outside of the lower part of the blower casing 50 which is bolted to the upper part by four bolts 80. The air therefore, passing through the tubes 88, enters the annular air chamber 85, then passes through annular slots 83 into the passage between the housing 82 and the shield 84. The air is drawn through this passageway by the suction created by the fan 8 I. The air,

however, is also drawn through the motor itself by the action of fan 8|, assisted by a smaller fan 82 on the same vertical shaft I03; this discharges the air into the hollow hub of the fan 8| and out through holes 83, thereby cooling the inside of the hub so that very little or no heat is transmitted to the shaft by the fan blades. A throw ring 94 prevents any dirt from falling down through the holes 83 or any rain or water of condensationfrom entering similarly. We have seen that the blower is in motion when in proximity to the stack and will remain in motion until taken out of the operating zone. Therefore, if any steam should be discharged through the stack it cannot reach the motor because of the pro-visions just described.

This blower has two ball bearings ml, the oiling of which is accomplished as follows: Oil is poured into a receptacle 85 until it overflows through a hole having a plug 86 which is then secured in place. A pipe 8'! leads from the receptacle to the oil chamber I02 of the motor and this oil chamber will be filled approximately to the top of the lower ball bearing. A screw nut 98, rotating with the shaft I03, pumps the oil upward through a hole I04 through the center of the shaft, putting the oil in this hole under pressure. Above each ball bearing is an outlet I 05 from this hole and the oil flowing through the lower outlet will pass through the ball bearing and immediately into the oil reservoir, while a tionary rail the oil passing through the upper hole flows through the ball bearing into a chamber 99 then out through a pipe I00 back to receptacle 95. The flow of oil will continue as long as the motor is in operation. The pipe 97 passes through one of the air inlets 88 and therefore is kept cool, and the pipe Iflfi'passes through another pipe I96 which communicates with the air passage 83 for the same purpose. A relief over-flow Ill? is provided for the upper bearing.

With this construction, the steam pipes with which roundhouses are ordinarily equipped for the purpose of drafting the locomotives are entirely eliminated. This also eliminates the expense of installation and upkeep of these pipes and their supply from the boilers. Automatic means is provided for shutting off the power whenever it is not required. It is shut off mere- 1y by the movement of the blower away from the smoke jack and it is also turned on by the coming of the blower into position under the jack. The blower is held up also, if the locomotive is moved out when nobody is attending to the blower particularly, so that no damage is likely to be done from any inattention of that kind. The portable blower easily fitted to the stack of the locomotive even if the stack is not centrally located under the jack'or if it is tilted to one side. The blower can be carried quickly from one locomotive to another and is provided with means for protecting the motor against the heat of the gases of combustion and against steam from the steam jet blower if that is .irned on. Antomatic means is provided for lubricating-the bearings of the blower and also there is means for cooling the motor as it operates. This is a material improvement over the blower sys terns that have been installed heretofore because the blower is portable and no flexible or te1escoping pipes have to be used in connection with it that may be left open, thus wasting power.

Fig. 11 shows a. modified layout of the monorail system, in which the spur E25 is hinged at I26 so that the blower may be moved slightly to the left or right to take care of any tilting of the locomotive stack. The free end rests and slides on a horizontal bar I24. In this case the track normally moves directly under the smoke jack H3. I-beam is in the direct path of the gases of corn bust-ion which are highly corrosive. I have shown in Figs. 12 and 13 how the rail I25 can be pivoted on the stud I26. The pivot stud is mounted on a plate I23 secured to the bottom of a sta- I2'I. Overlapping plates I28 and I29 are ecured to the tops of the rails i252) and In this case the rails and. trolley may be the same as above described but the blower casing is considerably modified as shown in Figs. 1a, 15 and 16. The flared intake I 39, instead of being fixed to the blower casing as in Fig. 7, telescopes with one or more sections or collars IEii. These sections are moved up and down by two chains or ropes I32 running over quadrants I33, one of the quadrants having an arm 34 with a chain I to operate it from the floor. There-- fore, instead of moving the blower up and down, only the intake is moved up and down and no hoist is necessary. The blower is suspended by a link E36 pivotally depending from the trolley.

In the form shown in Figs. 17 and 18 the blower casing is suspended by chains 8 and a yoke 8 iulcrumed at 8 in a lug 8 of the blower casing. The chains 8 are the load chains of a This has the disadvantage that the geared trolley hoist 9, the trolley of which runs overthe spur I25 of the monorail system which is suitably supported by hangers. The jack H is provided with doors I2 which are pulled open by a chain I3 over a pulley, sufficiently to allow the blower to enter the smoke jack. After the blower has entered the smoke jack the doors are allowed to close by their own weight or by suitable springs or counter-weights, not shown, provided for the purpose. The blower has a flared or conical intake l5 which rests on the locomotive stack to locate and center the apparatus thereon, the blower being moved up and down by the operating chain I6 of the hoist. By operating the chain I! of the geared trolley the blower is movedin or out of the jack.

Figs. 19 to 22- show the blower with a screw hoist instead of a chain hoist, as previously described. The blower is suspended from the screw rod 20, .iulcrmned at 2| so that it can swing slightly out of its normal position in order to set squarely on the locomotive stack if the locomotive should be tipped to one side. Bracket 22 which is fastened to the blower outlet, has a fork 23, the arms of which are guided by the fiat sides of the housing 24 of the screw hoist so that the blower and the hoist rod 25 are prevented irom turning around the center of the rod.

The blower itself consists of a housing 3!] having an intake elbow 3| provided with a flared inlet 32. .Tothe upper part of the blower housing is bolted a fancasing 33 with a hub 34 containing a bearing 35 through which passes the shaft 3%. The bushing 35 is provided with prongs or ribs on the outside so that air passages 55! are formed between the hub 33 and the bush-- ing. The hub 3 1 is fastened to the casing 31% by means of ribs 34 and between these ribs are gaps 3t which are closed by covers and thus constitute air passages The inlet to the air passages 31 is closed by a pipe fill and the inlet to the air passages 34 is closed by a flat plate 4! and a pipe 42. This forms an air passage be tween the pipes Ml and 42 which communicates with atmosphere outside of the blower. Anair passage is also formed between the pipe 3!! and the shaft 36 communicating'with the passages 3i" and opening up to the motor casing. By the action of the fan 38 air is drawn from the outside between the

pipes

40 and 42 and also through the motor and around the shaft. At the extreme end of the shaft is the fan 38 discharging the gases into the blower outlet 39.

On the other end of the housing 39 is bolted the motor frame consisting of a cap t3, shell 1 and cap @5, the latter containing the other bearing of the blower. Thus the motor is locatedout of the path of the heated gases of combustion. The lubrication of this bearing is furnished by an ordi-- nary grease cup screwed into the cover 68 and the grease pipe for the upper bearing is located inside of a sleevewhich is screwed into the hub so that there is an air passage between this pipe and the grease pipe for keeping the grease cool. A guard 45 protects the motor.

' The casing 3B is provided with two doors one on each side, which, when the blower is not in operation, hang open as indicated, when the blower is started up a suction is created inside of the blower housing, which automatically closes these doors. These doors are for the purpose of letting cold air into the blower housing if the blower should be allowed to remain on a stack not in operation, thereby, reducing the temperature so as to fit in the conical inlet.

of the gases and consequently the'lheat to which the bearing 55 is subjected. The motor is. provided with long wires for. plugging in the motor at a convenient place for each stall; I

In the form shown in Figs. 23 to 25 the casing 58 supported in the way shown in the first three figures or in any other desired way, is

adapted to be inserted in the flaring conical inlet M0 at the bottom of a flexible hose I 4] so that the hose can receive the gases drawn up through the blower. The blower casing hasa conical top The hose MI can be formed of rubber lined with asbestos or other material to stand the heat of the gases to which it is subjected. Its upper end has an outlet ring I42 which is .held up by chains I43 running over pulleys I44 and held up by a counterweight I45 preferably inthe form of a ring almost heavy enough to pull up the hose.

The parts just above described are located in the chimney Hit and no smoke jack is required although they can be located in one if desired. On the inlet I are attached three or more chains I l] running to pulleys I48 in different di rections and hanging down. so that they can be operated to move the hose around with the: blower on it, or without it, but ordinarily when the blower is on it the blower will be manipulated as in the preferred form shown. The blower can be put on the stack of a locomotive as shown in full lines in Fig. 23 and if the locomotive is drawn back it will go with it, as indicated in dotted lines in that figure. However, it is to be noted that in the dotted line position the blower 5% is missing. lhis is to show that the inlet I40 can be applied directlyto the top of the locomotive stack to direct the gases up in the chimney without a blower at certaintimes. It will be understood that the counterweight I is heavy enough so that by manipulating the inlet I40 the whole hose may be raised and lowered in the chimney. It is adapted to be applied to a locomotive smoke stack. with the blower between whenever the locomotive is approximately under the chimney and no matter how much it is tilted to one side.

In the form shown in Fig. 26, the blower 50 is provided with a weighted ring I50 at the bottom and it is otherwise constructed as shown in the first form of the invention illustrated. Its trunnions are employed to allow it to be picked up by an ordinary crane which can set it around wherever desired on a locomotive. In this case, the locomotive being placed under a steam jack as before described, the crane will move around and place the blower on the stack of the locomotive and it will be substantially centered thereon, and be prevented from becoming laterally displaced, by either the clips I5 I or the flange of ring IEEI, both of which serve to restrain the blower so that it will not be dislodged accidentally. The blowerwill beconnected with the electric supply in any desired way and will discharge the gaseous products of combustion up the smoke jack or chimney. When the operation is finished, the cranewill be employed tomove it away. This heavy ring I50 is employed to keep the blower right side up and to insure its hanging down straight from the crane and furnishes also a limit at the bottom to keep it from sliding about to any material degree on top of a locomotive smoke stack.

The specific blower mechanism and the modifled forms are not claimed herein in detail as blower,

they constitute the subject matter of two divisionalapplications.

Although I have illustrated and described several forms of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.
