Application, filed February 1.5, 1910. Serial No. 5 13.909.

To (iii whom it may omcez n:

it i iitouuu A. JORDAN. q. Mates, residing in the borough of 'ii'ooldyn. county of Kings. cit and ii ale of blow York. have invented it certain new ltl useful llleciric (lutlflut, oi Whicl the ol owing is ii upecilicution.

The oliioct i have in \ieu' is the roduw iion of :1 cu. 'L' nit breaker For electric circuits Winn-l .l'll lie or "irely in :l .i.--:e(l, wiil be ac 2 ale to the ui'u'lcru'riti will he of ininiirwu size uud entirely Wale and gas proof, \vla' h cannot ie tampered with, uiii'll ly lo got out of order and Wiil he cheap to (.O-llliilflk'i and (lin'ahlc. "lhcso and further ohjccin will appear from the following specification and :uzcompunying drowings considered together or separately.

In the drmviugs: Figure 1 is n. plan View of a switch and switch hot: cinhodying my invention. showing the cover iri-inioved; and Fig. 2 is section. on the line 2-2 of Fig. 1, showing the cover.

I n both of thee views like parts ere igniited by sinii" r *rcncc cluirzicters.

in the enilmdinient chosen for illustration, 1 mount a. switch wit" '1 a completely inclosed llPQX The how: (.fiJYiQI'lSQS a hody 1 and a cover and is best made rechu'igulaw in shape,

. the top and hot-ton), of the box are couplings or conduits 4., lfor the entrance and egress of the circuit Wires. Within the box is a switch 5. This switch is shown as of the ordinary two polo iv and coi'i'iprises con- .orn: oi. double jlilexi i 1 min/inn; member 'Z..in the fe elen'icnts 8, S pivfree ends C(Ill'flfifitfid unn hur 10, by means t 9, mid v.1; by on in oi wh 1n the switch. may be opened and cloned in the nuinnci: usual to such switches. These elements ol? the switch are supported upon the usual .insuizitinnj base 11, Which is shown the hex. .i'hS ehown in Fig. 1, the upper loads 12, 12 come in at thev top of the box and are connected electrically to the

contact gnemher

6, 6. The

lower lends

13, 13, which pass out through the lower side'of the box, are connected to the pivot contact 9, by len ths of wire-14E. Between the Wire 14 and scanned by screive to the bottom.- of

the lead 13 on each side is interposed :1, fuse 15. Each fuse is secured to e. block 10 of slate or cthhr insulating n'uitcrizil which lies alongside the hose 11. The blocks 16 are Se"- cured by screws or other suitable means. of attachment to the bottom of the body 1. The \Vilt. 14 on each Flili. lies within a groove formed on the inner side of (he block 16 where the said. hiocl; engages with the side of; the base ll. By this conel'ruction the length of the switch is very much more re- (luccd than thosse hi. totorc made. in which the tunes; lie at the ends, as distinguished from the side of the witch. This permits a.minini'unisized box, as the present rules of the underwriters require at least an inch space between the insulating hose and the inuidc of the metal box.

The second fcziturc of my invention resides in the means for opening and closing the switch from the outside of the box. This means CODIPIl'SGS a. rod connected to the switch arm and passing through a stufling loox, and provided with an operating handle on the outside of the box, and being hinged, so that, when the switch is; opened, the prol'llldllll" portion of the rod can drop out of 23 the Way.

Referring to Fig. 2, the COVGZ 2 has an opening 1.? through which a rod 18 passes. The inner end or" this rod is pivoted 19 to the insulating bar 10 of the moving poi tion of the switch. The outer end of the rod which extends beyond the face of the cover is provided with a. handle 20, by means of which it may be manipulated. B pulling; out or pushing in the handle, the switch will he opened or closed and turn from the full line position to the dotted line position. The rod provided with a joint 21 NlIBICby. when tho switch is open, the portion extending outside of the joint will hangdown vertically, as shown in broken lines in Fig. The position of the joint should be such that this can be done.

For the purpose of excluding moisture or ,gas from the inside of the switch or, to prevent the panning ou'lt of lire. if a short circuil; occurs in the switcln the rod 18 is' between theballand the'opening 17 is made tight and'at the same time the ball can turn in order to accommodate the changing angle of the rod when the switch is opened and closed.

In order to prevent tampering with the switch, I may incase the handle 20 as shown in Fig. 3. The cover 2 may be provided with an annular flange 27 surrounding the opening: 17 to which may be removably' secured a cap 28 covering the handle 20 and lands 23 and 25. 1 ,It will be noticed that my improved box is divided through the middle and has anarrangement which permits an inclined face on the front where the opening 17 is located, so that this opening is at right angles to the planeof the cover and parallel to the normal plane of the rod 18. This makes a better joint between the rod rand-packing than would be possible if the front portion of the box were not inclined. 'It also reduces the size. of the box, as will be seen from an examination of Fig. 2.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other ways.

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

1. An in'closed switch which comprises a box, a pivoted switch element within the box and a rod connected to theswitch element and passing through a wall of the box, said rod being surrounded at the wall with yieldingpacking to permit the plane of the rod to change asthe switch is opened or closed.

2. An inelosed switch whichcomprises a box and a pivoted switch element within the box, a rod connected to the switch element and passing through a wall of the box, a ball joint at the wall, said joint permitting the plane of the rod to change as the switch is opened and closed.

3. An inclosed switch, which comprises a box, and a pivoted switch element within the box, a rod connected to the switch element and passing through a wall of the box, a ball joint at the wall, said joint permitting the plane of the rod to change as the switch is opened and closed, packing around the rod and within the ball, and a gland carried by the ball.

4. An inclosed switch which comprises a box and a pivoted switch element within the box, a rod connected to the switch element and passing through a wall of the box, said rod being jointed so that when the switch is opened the outer part of the rod is free to hang down.

5. A switch in combination with a box, said box having an inclined front portion with an opening therein and a rod passing through the opening and connected to the switch, the rod normally lying substantially at. right angles to the inclined portion of the box, and means carried by the front portion to permit the plane of the rod to change as the switch is opened and closed.

6. A11 inelosed switch which comprises a box, a pivoted switch element within the box, a rod connected-to the switch element and passing through a wall of the box, means carried by the wall to permit the angle of the rod to change, a joint in the rod, the free end of the rod beingrorered by-a removable cap when the switch is closed.

This specification signed and witnessedthis fifth day of February, 1910.
