PATENT OFFICE PARKWAY CABLE OUTLET Application August 4, 1937, Serial No. 157,289

6 Claims.

This invention relates to improvements in parkway cable outlets especially adapted for use in connection with railway track circuits. Such outlets are generally referred to by the trade as bootlegs,

In outlets of this character, the parkwayv cable is brought up through or carrled in a hollow member to a fitting fastened to the top of the member and over an opening therein. To this fitting are attached wires or cables running to the signal circuits, or bond wires leading to the track rails.

It is one of the objects of my present invention to provide an improved form of outlet or fitting which will expedite the work of making connections between the parkway cable and the outgoing wires or cables leading from the bootleg or fitting. Another object of my invention is to provide an outlet iitting in which certain difficulties encountered in other types of outlet fittings are overcome, and which, at the same time, is cheap to manufacture.

These and other objects will be clear to one familiar with these devices after a reading of the specification taken in connection with the annexed drawings, wherein:

Figure 15 shows a modified form of holding the cup to the fitting.

Referring now to the details, wherein like numbers refer to correspoding parts in the varous views, I is a hollow standard, over the top of which is positioned a fitting 2 having an annular rim or fiange 3 which is slotted at i to provide a pair of lugs 5, only one of which is shown in Figure l. The lugs 5 are provided with holes through which a clamping bolt 6 passes for drawing the lugs together to clamp the flange 3 around the upper end of the standard i. An insulator l is preferably used to insulate the fitting 2 from the standard I. The fitting 2 preferably has an enlargement or thicker portion 8, within which is located a threaded stud 9. Preferably the stud 9 has a iiat portion IB to prevent the stud from turning inthe fitting. In construction, the stud 9 is cast with the fitting 2.

A clamping member II fits over the stud 9 and is grooved at least on one face to receive the outgoing bond wires or cables l2 and I3, it being understood that the large portion 8 of the tting 2 is also provided with cooperating grooves to receive these cables. As shown in Figure l, the upper surface of the member Il has an annular groove adjacent the hole therein to receive the end of the parkway cable Il! coming up through the standard i. After the end of the parkway cable is passed around the stud 9, it may be carried out through the side of a cap I5 and twisted around the cables I2 and I3, and preferably soldered or welded thereto although this is not necessary as it is clamped securely between the clamp II and washer 6I by nut Il and lock washer I6 in which case it would terminate at point t2. The lock washer I6 and nut I'I complete the clamping means for holding the parkway cable and outgoing conductors or cables securely in electrical contact with each other and the stud 9.

It will be noted that there is no opening in the top of the cap I5 so that the capfcompletely covers the stud and the clamping means. The cap t5 is held to the tting 2 by providing on the fitting a plurality of upstanding lugs I8 `and. I9 which are threaded to receive screws 2d which pass through the cap I5 near its rim.

In Figure 4 the stud 9 is in the form of. a carriage bolt having a head 2| embedded or moulded into the portion 8 of the fitting 2. In this type of stud, the square portion 22 is provided to prevent the stud from turning in the fitting. Also, the fitting 2 is provided with a recess 23 into which a sealing compound may be poured to seal the hole through which the parkway cable I4 passes. In this construction, more particularly shown in Figures 5 and 6, the fitting 2 is in the form of a plate having ears 24 and 25 provided with holes through which fastening screws 26 may pass to hold the fitting 2 to a pump log 21. The cap I5 is fastened to the fitting 2 in the same manner as in Figure 3.

In Figures '7 to 10, the cap is not shown and the stud 9 may be fastened to the member 2 as shown or as indicated in Figure 4. In these particular views, the clamping member 28 which engages the cables I2 and I3, is preferably grooved on the engaging side but the parkway cable- I4 is anchored in a different manner. The clamping member 28 is provided with a hole 29 intermediate one edge of the member 28, and the hole for receiving the stud 9, and it is slitted or split at 3|] through the hole 29. The hole 29 is preferably made in the member 28 in substantial alignment with the hole 35 in the fitting 2. The slit 30 may extend all the way to the hole for the stud 9. The member 28 is also provided with a` hole, at right angles to the split portion and the hole 29, to receive a bolt 3I which is used to draw the two split parts of the member 28 to clamp the parkway cable I4 securely in the hole 29. The member 28 is provided with a notched portion 32 to receive the head of the bolt 3| to prevent its turning when the nut 33 is drawn up against the lock washer 34.

By constructing the member 28 and securing the parkway cable thereto in the manner described, the cap I5 may be removed and the nut I1 and member 28 loosened on the stud 9 so that bond wires or outgoing cables may be changed or replaced without disturbing the connection to the parkway cable.

While I have indicated the studs 9 as being initially separate machine parts to be cast with the fitting 2 and thereby become a substantially integral structure therewith, the studs may be cast directly with the same material as the fitting 2 and threaded thereafter, but in either case, the studs 9 are so positioned in the fitting that they cannot drop out of the fitting into the hollow member to which the fitting is applied when the nut I1 is removed, and connections are being made to the fitting.

In Figures l1 and 12, the fitting is divided into two parts, one of which, 36, has a flange 31 adapted to slide over the end of the standard I and fastened thereto by set screws 38 and lock nuts 39. The member 36 has a pair of projecting ears 40 adapted to receive cooperating ears 4I on the fitting 36a. 'Ihe two parts 36a and 36 are separated by an insulator 42 and are held together with a plurality of screw studs 43 which are insulated from the fitting 36a by insulators 44 and bushings 45. The enlarged portion 8 of the fitting 36a has fastened thereto a pair of studs 46 and 41 which carry a pair of clamping members 48 and 49, the member 49 having arcuate recesses in its ends to lit around part of the periphery of the studs 46 and 41, while the member 48 is preferably provided with holes through which the studs 46 and 41 pass. The enlargement 8 and the member 49 are provided with cooperating grooves to receive the bond wires, and the member 49 is also provided with a groove to cooperate with a corresponding groove in the member 48 to receive the parkway cable going out oi' the standard through the hole 50 in the fitting 36a. Nuts 5I and lock washers 52 on the studs 46 and 41 are used to draw the clamping members 48 and 49 into locking position to bind the bond wires and parkway cable into permanent position on the fitting.

Preferably the enlargement 8 of the fitting 36a is of sufficient diameter to readily receive set screws 53 for holding the cap I5 in position,

similar to that shown in Figure 13. The cap I5 may be held in place by extending one of the studs 46 and 41 so that it passes through the top of the cap I5, in which case a lock washer and nut are used to hold the cap in position. If the studs 46 and 41 are screw-threaded into the enlargement 8, they are preferably staked at the point 54, but when they are moulded in place, they are formed and arranged as is the stud 9 in Figures 1 and 7.

In Figure 13 a single stud 9 is used, on which is carried a cable-connecting member 55 which is provided with a plurality of cross-holes 5G to receive the cable. 'Ihe member 55 is slotted or split at 51 and is further provided with bolt holes 58 to receive screw studs 59 for drawing the said split ends together to clamp the cables in their respective holes 56. The member 55 is clamped securely to the stud 9 and the fitting 36a by a lock nut 60. Preferably, the stud 9 is cast into position as in Figures l and '7.

As indicated in Figures 11 and 13, the enlargement 8 may be of a diameter sufficiently large so that set screws 53 and lock nuts may be used instead of the separate lugs I9 and screws 2D, as indicated in Figure 5, from which it will be observed that certain of the details may be varied without departing from the spirit of my invention or the scope of the appended claims, for example the cap I5 may have an annular fiange or ears S3 as shown in Figure 15, for fastening it to the fitting 2 of Figure 5 for example, or the fitting 36a of Figure 11.
