CH115.1111511GrU'IDIEl` FOR PULL-SOCKEl/TS.
-To au rwnom u mary concern: A
Be it known that I, HARVEY HUBBELL, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Chain-Guides for Pull-Sockets, of which the following is a specification.
This invention has for its object to provide a chain guide for pull sockets which shall comprise a bell or funnel-shaped guide for the `chain and a bracket by which the bell is carried and which may alsoserve as a third leg or connection between the insulating blocks.
With this and other objects in View I have devised thenovel chain guide and strengthening bracket for pull sockets, of which the following description in Jconnection with the accompanying drawing is a specification, reference characters being used to indicate the several parts.
Figure 1 is an elevation, partly broken away, illustrating the application of my novel chain guide to the insulating blocks of a pull socket Fig. 2 a detail view-partly broken away to show the construction of the guide and the mode of its attachment to the bracket; Fig. 3 a detail view illustrating a form in which the guide is made longer and is detachable from the bracket; and Fig. 4 vis a detail view illustrating a modified form in which the bracket is adapted for attachment to one only of the insulating blocks.
10 and 1l denote respectively the upper and lower insulating blocks ot'. a pull socket and 12 the usual current-carrying brackets or legs by which the insulating blocks are connected.
13 denotes the bell or guide for the switch operating chain (not shown) which is carried by a noncurrent-car1iying bracket 14 provided with arms l5 which are connected to the insulating blocks by screws 16. In practice I place bracket 14 approximately opposite to brackets 12A and thus secure three points of connection between the insulating blocks instead of two 'as heretofore, thus adding greatly to the strength and rigidity of the structure and increasing its efficiency Specication of Letters Patent.

in use. The bracket 14 is struck up Land formed complete from sheet. metal and is provided with a raised boss 17 having a central opening 18. The bell or guide is drawn from a disk of sheet metal and is provided with a neck 19 which is passed through opening 18 in the boss and is closed down upon the under side of the boss as at 20 in Fig. 2, thereby locking the bell rigidly in place.
In the form illustrated 1n Fig. 3, the bell is provided with an elongated neck indicated by 21, the inner end of which is externally 'screw-threaded to engage a correspondingly threaded opening in boss 17 as at 22.
The modified form illustrated in Fig. 4 differs from the form illustrated in Fi s. 1 and 2 only in that one of the arms 15 o the brackets 14 is omitted, and said bracket is adapted for attachment to one only of the insulating blocks, ordinarily to the lower block. i
Having thus described my invention I claim:
. 1. The combination with insulating blocks and current-carrying brackets by which they are. connected, of a chain guide comprising a bell and a non-current-carry-V ing bracket secured to an insulating block.
l2. The combination with insulating blocks and current-carrying brackets by which theyA are connected, of a chain guide comprising a non-current-carrying bracket having an attaching arm and a raised boss with a central opening and a bell having a neck which is passed through said opening and closed down on the under side to secure the parts together.
3. The combination. with upper and lowerl insulating blocks and currentcarrying' brackets by which they are connected, of a non-current-carrying third bracket placed opposite and secured to a block and a chain guide carried by said bracket.
In testimony whereofl I affix my signature in presence of two witnesses.
