To all whom it may concern:

Be it known that I, EDWIN J. Amw srnono, a citizen of the United States, residing at Erie, in the county of Erie and State of,

a to a steam shovel in which is used a hoisting engine, swinging engine and crowding engine; These engines are used intermittently some of the time, simultaneously and some of the time independently. 4

The object of the invention is to simplify the lubrication of a plurality of engines receiving their steam from a common supply.

The invention is illustrated in the accompanying drawings as follows Figure lis a plan view of a shovel. Fig. 2'

1 marks the shovel frame, 2 the axle, '3 the supporting Wheels, 4 the swinging table, 4 the boiler, 5 the boom, 6 the hoisting engine, 7 the steam pipe connecting the boiler with the controlling valve chest 8 from which steam is distributed to the hoisting engine, 9 the steam chests of the hoisting engines, 10 the swinging engine, 11 the steam chest of the swinging engine, 12 a pipe for supplying steam to the steam chest of the swinging engine, 13 branches from the pipe 12, connecting the pie 12 with the steam chest of the hoisting engine, and 14 a steam pipe leading from the pipe 12 by way of the joint 15 along the boom 5 to the steam chest 16 of the crowding engine 17. The hoisting en gine; operates a gear "18 which meshesthe drum gear 19.- The drum gear is carried by drum 21is arranged on the shaft20 and operates in the usual manner. A gear 22 is arranged on'the shaft 20 and meshes a gear 23 on the shaft 24. A beveled gear 25 is fixed onthe shaft 24 and drives a ,gear26.

The gear 26 is arranged on the shaft'27 at the axis of the turn table. A connection is made With the shaft 27 for driving 'the' wheels of the shovel soas to permit of the a shaft 20 in the frame 6 of the engine. The

movement of the shovel from one placeto 7 another under its own, power. When the hoisting engine is not being used for this purpose the driving mechanism is "thrown out of action by means of the clutch 20". The swinging engine drives a beveled gear 28. This meshes ajg ear '29 on the shaft '30.

Thetable 4 is swung through the movement of the shaft in'the usual manner. :The crowding engine 17 drives a gear '31'on the crank shaft 32. The gear 31; drives a gear 33. The. gear 33 is arranged on ashaft 34 and the gears 35 are arranged on the shaft 34 and are adapted to operate the. dipper stick (not shoWn)., The steamengines in a general way operate in the usual manner and the several -engi-ne'sperform their usual functions, f 1

[The hoisting engines have the cylinders 36 (see 7). {These .areconnected with the steamchests 9 ,by'the ports '37. Steam pas- 7 sages 3'8 and 39 also lead to the valve surface of the steam chest 9. t The

passages

38 and 39 are connected with the passages 40 and '41 respectively the passage plate 8?. Thepassages 4'0 and'41 are connected by the

ports

42 and 43 respectively with, the;

controlling chest 8.": The engine valve 44fis of the usual type and has the valve port 45 adapted'to couple the passage 38 with either of the ports 37 in the operation of the engine and also the port 46 adaptedtocouple the ports 37 with the passage 39'. Steam is introduced through one of the

passages

38 or 39 and exhausted from the other. By reversing the flow of steam in these passages, the engine may be reversed. This is a common method of accomplishing this in engines of this type. Thevalve 44 is driven through the ,valve rod .47 The controllingv valve 48 i has the valve passage 49 adapted to couple either the

part

42 or 43 with the exhaust port 50. The exhaust port is connected with the exhaust passage 51. The controlling valve as operates between the side walls 52 making a rather loose fit withsaid walls. Leading from these side walls are the passages 53 in the passage plate 8. These passages 53 connect with the passages 54 leading to the steam chest. The purpose of the steam delivered through the passages 53 to the hoisting engine is to hold the valve 44 to its seat. Steam, therefore, is in the passages 53 at all times when the steam is on the controlling chest. Steam is delivered to the controlling chest through the steam pipe 55.

The valve athas the opening 56 in its rear face and is also open at the sides so that steam may at all times pass from the controlling valve-chest tothe passages 53. A nipple 57 extends through the wall of the valve chest and into the opening 56 in position to deliver a lubricant on the interior of the valve 44:. The nipple 57 is connected by a pipe 58 with an oil pump 59 (see Fig. 2). The pump is of ordinary construction being driven through a rock shaft 60. A rock arm 61 is arranged on the rock shaft 60. A link 62 connects the rock arm with a pin 63 on the valve rod 47. The valve rod has the pin 64. An eccentric rod 65 extends from the pin 64; to the eccentric 66 on the crank shaft 67 of the hoisting engine 6.

Oil is delivered at all times during the operation of the pump. With a steam shovel this is intermittently so that there is more or less oil at the interior of the valve at all times. There is no passage of steam practically through the passages 53 except when either the crowding or swinging engine is operated. There is, therefore, a pulsation of steam through the joint between the valve 44 and the side walls 52 and also around the ends of said valve as the hoisting engine is operated. This is sufficient to deliver a proper amount of lubricant from this source to the hoisting engine. It also prevents too great an accumulation of lubricant in the passages 53-53. When either the swinging or crowding engine is started steam passes through the passages 53 carrying with it the lubricant. This lubricant is carried through the valve chest 9 of the hoisting engine, thus leaving some of the lubricant in the chest for this valve in addition to what is carried to this chest with the steam going to the hoisting engine. The lubricant is carried with the steam to the swinging or crowding engine. In this way a' single lubricating pump insures a perfect lubrication of all three engines.
