BOILER-SKIIVL'MEB.

Application filed October 1 T 0 all whom it may concern.

Be it known that we, Noi-usnnr SOHREIBER and RAPHAEL fiosmzrnaii, citizens of the United States, residing at Lincoln, in the county of Logan and tate of Illinois, have invented a certain new and useful Improvement in Boiler-fikimmers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to boiler skimmers for skimming or taking off the scum or refuse matter on top of the water in the boiler.

Prominent objects of the invention are to provide a simple and practical construction of device of the class mentioned; to simplify the same, reducing the number of parts to a minimum and making the construction inexpensive; to provide simple and expeditious means for withdrawing and disposing of the skimmed matter; to provide a form of device particularly adapted for use in locomotive boilers; to arrange for the advantageous use of the skimmed matter in assisting the traction efforts of the locomotive; and to secure the foregoing and other desirable results in a simple and expeditious manner.

In carrying out our invention in the manner herein set forth, we provide a suitable frame conveniently made of pipes or pipe sections connected together and supported by attached floats, whereby said frame may easily rest or float upon the surface of the water which is to be skimmed. .T his frame has suitable apertures or openings to permit the entry into it of the skimmed matter which apertures or openings form a suitable surface intake. A convenient arrangement is to have the sides of the pipes provided with apertures or openings in the form of circular holes, although of course this arran gement of surface intake could be varied. The floating frame is connected by a loose or movable connection with a suitable outlet pipe, whereby the skimmed matters may be withdrawn and discharged.

As a further improvement the frame may be made of substantially rectangular and oblong form so as to fit into the rear upward portion of a locomotive boiler, one end of the frame being elevated so as to pass over the top of the dry pipe of the boiler, and the outlet or discharge end of the device may be Patented 28, 1915.

conveniently connected with the throttle valve of the locomotive whereby the dlscharge may be regulated by the throttle.

its a matter of further and specific imbe increased.

In the accompanying drawings Figure lis a plan of a boiler skimmer embodying our present invention; Fig. 2 is a side elevation of the same; Fig. 3 is an end elevation of the device; Fig. i is a view of a portion of a locomotive boiler showing our improved skimmer embodied therein; Fig. 5 is a horizontal section of a portion of the device showing certain details of construction more fully.

Referring first to Figs. 1, 2 and 3, we snow a frame A. which is preferably made of general rectangular form as shown in Fig. 1. Said frame is desirably made of pipe sections as 1, 2, 3, ek and 55, sections 5-5 being vertical and supporting the elevated sections which are connected by coupling 6. The outer sides of the pipes l, and 3 are preferablv rovided with apertures or openings 7 (Figs. 2 and 5), so as to provide a surface intake for the refuse or scum to be skimmed off the top of the water.

l loats l010 are provided to support the frame A. Preferably four floats 10 are employed, conveniently located at or about the corners of the frame A as shown in Fig. 1. These floats may be arranged or connected in any suitable way so as to support the frame A, a convenient arrangement being that shown in the drawings wherein side pipes 11-11 are provided and the floats 10 mounted upon them, each float having a threaded connection, as shown at 12 with the pipe 11 whereby it may be adjusted with reference to said pipe. The side pipes 11 are supported by small cross pipes 14.1st connected to the main pipes 11. The floats 10 are preferably elongated as shown in the drawings, whereby they may be arranged close to the frame A.

An outlet pipe 15 is connected by a T-shaped coupling 16 with the pipe 2, the coupling 16 being preferably loose so as to give it a rotary or swivel connection with said pipe Said pipe 15 is connected at its other end to another T 17 which is mounted loosely upon a short pipe section 18 (Fig. 5) connected by a yoke 19 with a pipe .20. The coupling 17 is also mounted for rotation or swivel movement upon the pipe section 18, whereby an up down movement of the frame A is permitted by the outlet connection 15, the ends of the pipe 18 being conveniently closed by plug caps 21. The pipe 20 may be any suitable discharge pipe extended to any desired locality to effect a proper discharge of the refuse matter skimmed from the top of the water.

The construction just described is particularly advantageous for use in a locomotive boiler and is so shown in Fig. i. In such case elevated pipes t--it are located above the dry pipe of the locomotive, a portion of whose boiler 2% is shown in the drawings, the frame A being of suitable size to fit conveniently within the rear of said boiler, as shown. In this case the outlet pipe 20 is desirably extended back to the rear of the locomotive and provided with a valve 25 having a link and lever connection 26 and 27 with the throttle lever 28, whereby the discharge through the pipe 20 may be controlled by the throttle. When the lever 28 is operated to open the throttle valve, the valve 25 is opened so as to ser nit a discharge from the skimmer and when the lever 28 is operated to close the throttle, the valve 25 is also closed, whereby there is a continuous blow-off from the skimmer while the engine is running, or at least while it is receiving steam for operation.

As a matter of further improvement we show a supplemental discharge pipe lead ing down almost to the track 30 on which the locomotive runs between the driving wheels thereof. In this way the refuse matter from the boiler may be discharged upon the track and so help the traction of the engine. The pipe 29 is preferably provided with a separate hand valve 31 by which discharge through said pipe 29 may be further controlled.

It will be understood that changes and modifications may be made without departing from the spirit of the invention. It is also understood that the elevated pipes -'l4 are particularly intended for use in a locomotive boiler and that when tae device is used for other purposes said end pipes would preferably not be elevated but would be in more or less the same plane with. the pipes 1, 2 and It will be seen that by making the device of pipe sections in this way great economy and expediency in manufacture are secured, because no special fittings, casings or patterns are required, pipe sections of standard pipe being used.
