A CORPORATION or NEW YORK Application led January 22, 1929. Serial No. 334,169.

This invention relates to switch stands, and more particularly to stands of the automatic type and'tor a new and improved housing therefor `by meansv of which the operating 55-parts are protected from the elements.

In switch stands of the automatic type, for example,

those shown in the patents to Snow et al. No. 882,024, March 17, 1908, and Strong October 3, 1911, it is desirable No. 1,005,081, to provide a housing which is capable of protecting the operatingl parts from sand and snow. The housing should preferably be constructed so as to. permit ready access to the adjustment of the parts.

various parts for purposes of inspection, oiling and adjustment without interfering with the operation ofthe switch or the relative It is also desirable to so construct the housing that certain portions thereof may be replaced when desired withoutdismantling the entire switch stand. In accordance with the present invention the housing comprises a central casing which surrounds the spindle and automatic locking mechanism, and is supported from a suitable base member in which the star wheel, springs and other necessary parts are contained.' A pair of separate cover plates are mounted on the base in a position overlying the springs and are provided with upturned iianges which cooperate with the central casing for preventing entrance of sand or snow therebetween. The cover plates are further provided with a downwardly extending flange adapted to overlie the hole which isl commonly provided inthe end of the base, to permit the spring to be properly tensioned. These cover plates are so constructed that sand, snow and rain are preventedl from entering the base member and interfering with the action of the switch stand.

. The invention also consists in certain new and original fe'aturesfof construction and combinations of parts hereinafter set forth and claimed. i

Although the novel features which are loe-v lieved to be characteristic of this invention ation'and the manner of its organization may be better understood by referring to the following description taken in connection with the accompanying dra-wings forming a part thereof, in which Fig. 1 is a perspective view of a switch stand showing the housing constructed in accordance with the present invention; i

Fig. 2 is a top plan view of the housing showing the relationship of the parts;

Fig. 3 is a section taken on the line 3e-3 of Fig. 2;

, Fig. L is a detail sectional view of a portion of the casing; and

Fig. 5 is a detail sectional view of the cooperating portion of the cover plate.

Like reference characters denotelike parts in the several figures of the drawings.

In the following description and in the claims parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.

Referring to the drawings more in detail, the invention is shown as applied to a switch stand of the automatic type including a spinfof which the switch is controlled. Handle 12 is shown as pivoted to a sleeve 13 and cooperating with a lock block 14 which is suitably mounted on a central casing 15. Spindle 10 extends through said casing 15 and terminates beneath baseol in a link 17 which is operatively connected to the switch by a connecting rod (not shown). Incorporated within base 16 and extending outwardly on both sides from the central casing 15 may be a pair of operating springs 20 which cooperate with suitable mechanism carried by spindle` 10 forl automatically operating said switch. The particular form of operating mechanism forms no part of the present invention and is accordingly not set forth in detail. A type ofapparatus which maybe employed is shown in the patents to and Strong above mentioned.

` Base 16 forms a closure for springs 20 and the associated operating mechanism and supports central casing 15. Said casing is provided with a bottom flange 21 which rests` Snow et al. v

upon base 1G and is secured thereto by bolts 22 extending through said base and clamped by nuts 23. Upstanding lips 211- are pro 'ided on opposite sides of casing and form with said casing ay channel which serves to catch foreign matter such as rain, snow or sand and prevent the same from reaching the mechanism enclosed within base 16. Casing 15 1s also provided with side flanges 25 which extend over opposite sides of base 16 for forming a tight closure therewith. Said casing may be supported by any suitable manner as from ties 26 to which it may be secured by spikes 27.

Cover plates 30 are of suitable dimensions to enclose the upper portion of base 16 on opposite sides of casing 15 overlying springs 20 and associated mechanism. Said cover plates are provided lon their inner end s with upturned lips 31 of sufiicient elevation to pass over nuts 23 and adapted to rest on lip 24 of casing 15 and to bear against the outer face of said casing. Suitable holes may be provided in lip 3 1 through which bolts 22 may pass, whereby said lip may be secured by nuts 33. Plates 30 are also provided with downwardly extending shrouds ,34 enclosing the end of lip 31, and forming in connection with casing 15 substantially a tight seal.I Said cover plates on their outer ends are provided with downwardly extending lips 35 which are adapted to cover the holes which may be provided in base 16 to give access to springs 20. Side flanges 36 fit over base 16 and form a` tight closure therewith.

It is to be noted that in the construction above described, fianges 25 of casing l5 and flanges 36 of cover plates 30 substantially surround base member 16 and prevent access of' the elements thereto. The upstanding lips of cover plates 30 permit the tached without disturbing nuts 23 which secure casing 15, and at the same time permit the cover plates to be secured without the use of additional bolts. The lips also cooperate with the upstanding` lips on the central casing for forming substantially a water-tight seal, while the shroudscomplete the enclosure.

For the purpose of adjusting springs 30, or for inspection, it is only necessary to remove nuts 33 whereby cover plates 30 may be lifted off for exposing the springs to view. This is accomplished without disturbing the central portion of the casing or any of the operating mechanism and without interrupting the action of the switch. Furthermore, should the cover plates become damaged they may be readily replaced without necessitating the replacement of the entire housing which would ordinarily require complete dismantling of the switch stand. Inasmuch as frequent inspection and .oiling are essential, it is obvious that the vimproved cover plates plates to be atcontribute to the safety of the switch stand and reduce the operating costs.

lVhile certain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various` omissions, substitutions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the inven tion.
