CARRIER Eon CABLE-CARRIERSYSTEMS.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed July 20, 1914. Serial No. 851,879.

1,071,018, dated August 26, 1918, which relates to an improved locking device for car.- riers, I have shown. a carrier which is not dissimilar in many respects to that herein. given by way of exemplification of my pres ent invention; but Ihave now succeeded in improving my former coi'istruction, so that the locking device is very much more simple and in certain ways even less subject to injury than is the device shown in said patent.

In fact, in the present case, the latch becomes peculiarl; apart or the carrier for reasons hereinaiter set forth.

In the accompanying drawing which forms a part hereof and in which like reterence characters designate like parts throughout the several views, I have exemplilied a preferred construction, but as I am aware 01 various changes and modifications whichma T be made herein without departing from the spirit of my invention, I desire to be limitedonly by the scope of the claims appended hereto.

Referring to the drawing:

Figure l is aplan view of a cable carrier.

Fig. 2 is a side elevation of said carrier.

Fig. 3 is an end view of the same.

F ig. 1 is a. bottom View of the carrier and Fig. 5 is a detail section taken on line V-V of Fig. ,1. j

The receptacle or body 1 of the carrier may be of sheet metal or other suitable mate rial and it the carrier is designed for use in a cable carrier system, the bottomoit' this receptacle preferably has secured thereto a fiber plate 2 which engages the rails or rods upon which the carrier travels.

A fiber block 3 serves to space the plate 2 away from the metal base t which may be provided with the usual lugs 5, which also engage the rails and retain the 02111'181'11'1 J turnedtlange or ed like. The pivoted stem 9 01 the jaw 6 carries a prong or tooth. 10 adapted for engagement with a spring 11, so that the aw 1s normally hold either in its open or closed position.

The spring 11 may be inclosed by an. areaate plate 12 which constitutes one portion of the inner wall of the receptacle proper.

All of the above mentioned elements are common to devices of this character and hence need not be further herein described.

The receptacle is provided with a cover or closure 13 which may be mounted upon a pin 1 1 and which isprcterably given a tendency for movement to its open position by a spring 15, mounted upon the center of the pin 14 between the hinge parts 16 of the cover. The cover iarries, preferably upon its outer side, a latch 17 pivoted thereto at 18 5 said latch preferably consisting of a fiat sheet metal strip, the free end 19 of which is bent up to form a handle for said latch.

\Vhen the latch is in its closed position, as shown infull lines in Figs. 1 and 2, this upo 19 is disposal in a recess 20 cut in the upper edge of the receptacle l, and it the receptacle have a, curved surface, as it is preferably given for cable *arriers, this flange may also be slightly areed to conform to the curvature of the box.

This construction renders the box very sightly in appearance and very effectively protects the handle from injury or from inadvertently engaging some one 01'' the operating parts of the cable system.

While in. my said Patent No. 1,071,018, the latch was caused to engage with a projection upon the inner wall of the receptacle, herein a reverse construction is employed to advantage; since no such projection is pres-- out and thereby the contents of the box, especially it bulky, may be more readily intro ing position.

facture is materially reduced.

There is a decided advantage in cutting the slot entirely througlrthelateral wall of the receptacle, since if this be not done, dust or dirt is apt 111 time to accumulate in the recess and when the latter has become clogged up, the latch cannot well be fully closed; whereas if the slot extends entirely through the receptacle wall, any clogging substance is automatically swept or pushed out of the recess each time that the latch is moved into operative engagement with the receptacle.

It is desirable to provide a stop to limit the unlocking movement of the latch, and to this end a rivet 23 may be secured in the cover, against the head of which rivet the latch comes to rest, as shown by dotted lines in Fig. '1.

Friction may be relied upon to hold the latch in its closed position and as long as the carrier is new such means for preventing I inadvertent opening of the cover may prove efficacious; but devices of this character are subject to rough usage, and after the latch has been operated a number of thousand times a mere clamping together into frictional engagement of the latch and cover cannot be relied upon. 7

I prefer, therefore, to indent or strike up the cover as at 24:, so that this struck up portion will bear against the inner edge of the latch when the latter is in its closed position as shown in Fig. 1.

The latch, being of sheet metal, is sufficiently resilient to clear this obstruction when the handle-flange is pressed inwardly by the finger of the operator, and it is preferable, for this reason, to shape the struck up portion 24:, as shown in Fig. 5, with sloping sides to facilitate the riding up thereupon of the shank of the latch.

If desired, this button, as we may term it, may also serve the additional function of maintaining the latch in its open position when moved thereinto, since the inner point of the handle 19, or some like portion, may bear against or be subject to contact with the button 24: when the latch is in its open position, as indicated by the dotted outline of the latch in Fig. 1.

It will be observed, therefore, that by virtue of the novel disposition of but few and very simple elements, a considerably imnzpved locking device for carriers is prov1 e 1n, conclusion I particularly desire to point out the value of recessing the edge of Having thus described my invention what I claim is:

1. A carrier receptacle having a closure, a spring acting to open said closure and means for resisting the action of said spring, said means including a latch lever one part of which is bent away from the closure to form a handle, said receptacle having a wall thereof recessed inwardly directly from the edge of the receptacle to form a pocket for the reception and protection ofsaid handle. 2. A carrier receptacle having a closure, a spring acting to opensaid closure and means for resisting the action of said spring, said means including "a latch lever one part of which is bent to form a handle, said receptacle having a wall thereof recessed for the reception and protection of said handle, and means for preventing inadvertent displacement of said handle from said recess.

3. A carrier receptacle having a closure, a spring acting to open said closure I and means for resisting the action of said spring, said means including a lever, a-latching part of which is disposed in a recess in a wall of said receptacle when said closure is locked,

said lever having another partthereofalso disposed in arecess in a lateral wall of said receptacle when said latchingpart is disposed in manner aforesaid.

4. A carrier receptacle having a closure, a spring acting to open said closure and means for resisting the action of said spring, said means including a latch element, a plu rality of spaced apart parts of which are reeeived into and protected by a wall ofsaid receptacle when said lever is in its locking position.

5. A carrier having a hinged cover, a latch therefor pivoted upon theouter side of said cover where its movements cannot injure articles disposed in said carrier, a lateral wall of said carrier having a short slot therein for receiving and engaging a part of said latch to hold said cover closed, said carrier having a receptacle part adapt.- ed to be closed by said cover and the walls of said receptacle past which articles being inserted into or removed from said receptacle may slide, being substantially smooth and unbroken by projections which would interfere with the said insertion or removal of said articles,

6. A carrier having a hinged cover, a latch therefor having a resilient handle, and

a button on said cover over which said handle may be forced when being moved to its closed position, said button adapted to hold said latch against inadvertent displacement either toward its open position when the cover is locked or toward its latching position when the cover is open.

7. A carrier having a hinged cover, a latch therefor having a resilient handle, and a button on said cover over which said handle may be forced when being moved to its closed position, said button adapted to hold said latch against inadvertent displacement either toward its open position when the cover is locked or toward its latching position when the cover is open, said button be ing struck up from the body of said cover.

8. A carrier having a hinged cover and a. latch having a handle part pivoted to the outer side of said cover, said cover being set into the body of the carrier when in its closed position so that the edge of the cam rier protects both said cover and its latch, said body being also recessed in said edge for the reception of the latch handle, the outer face of said handle being exposed through said recess to facilitate manipulation of said handle. y

In testimony whereof I have aflixed my signature, in the presence of two Witnesses.
