the carrier, at either end of the line, against inadvertent despatch or movement when the basket or receptacle. has been lowered or detached therefrom.

A further object is to preferably mount all movable locking or lock actuating elements upon the carrier itself so'that said elements traveltherewith. This tends toward simplification of the apparatus in so far at least as the accomplishment of the first mentioned object is concerned.

These and other objects of my invention will be hereinafter referred to and the novel means and combinations of elements whereby said objects are attained will be more particularly set forth in the claims appended hereto. 1 am aware, however, that various changes and modifications may be made in the construction givenby way of exemplification and I hence desire to be limited only by the scope of said claims.

In the accompanying drawing which forms a part hereof'and inwhich like reference characters designate like parts in the respective views, I have shown a preferred embodiment of my invention. 7

Referring to the drawing: Figure 1 is a partial side elevation of a wire-line basket carrier apparatus; portions thereof being broken away for convenience of illustration. Fig.2 is a side elevation of the carrier proper, also partly broken away. Fig. 3 is a plan view of said carrier; and Fig. 1 is a detail view of the basket or receptacle locking mechanism; together with fragments of the latch bolts, etc. i

The track 1 and guide wire 2 may be of the usual construction; and the commonly provided hanger 3, its station bracket 4 and Specification of Letters Patent.

Application filed January 26, 1914. I Serial No. 814,279.

A lock similar to that shown in detail in Fig. 4: has been disclosed in the patent to Gripe No. 615,505, dated March 13, 1900; so that the construction of the present lock need be but cursory. It comprises a knuckle 9 pivoted to the carrier frame at 10 and normally pressed into the position in which it is shown by a spring 11 the outer end of which bears against a pin 12 which projects inwardly from the side of the carrier frame which has been broken away. This knuckle is adapted to receive a portion of the basket frame, at 13 and to be rotated thereby, as in said Gripe construction.

Pivoted to the carrier frame at 14 is a spring actuated dog 15, the spring whereof is shown at 16 in Fig. 3. This dog is provlded with a tooth 17 which engages the flank 18 of the knuckle when the latter has been rotated counter-clockwise (as viewed in Fig. 1) by its engagement with the usual bar of the basket frame; the dog 15 being then free to drop into its dotted-line position. When the locking device is inits openposition however, in the present construction, tooth 17 bears downwardly against the arcuate surface 19 of the knuckle which holds the dog in its full line position as shown.

The dog 15 carries a trigger 20, pivotally connected thereto; a fiat spring 21 normally holding the trigger in definite relationship with respect to the dog. As in the Gipe construction, this trigger is raised fromits dotted-line position, which it occupies when the locking device is operatively disposed, to its full-line position by the stirrup 22, whereby to elevate the dog and thereby release the knuckle to permit of the withdrawal of the basket frame from its engagement with the carrier the stirrup being raised and lowered inz-the usual manner by the cord 8. The dog 15 has, in my preferred construction, an extension 15, the function tered or :positioned with respect to the 1 respective brackets 4 by buffer and recoil springs 26 and 26. Extensions '24: of parts 24 (also have threaded through them the lower or ,guide wire 2,:to hold said parts against rotatlon. These extenslons also each 'frictionally engage a lever 27, whlch 1s pivvoted at 28 to the corresponding bracket 4, and which, further, has attached thereto an upstanding link 28 to which s suitably connected ,(as bymeans of a clevis which is also pivotally connected to an arm 29' of the station) the corresponding end ofthe track- Wire 1.

.and 4, it will be noted that two bolts29 and 30 are slidably mounted in the respective ends of the carrier, said bolts extending through suitable apertures "in the ribs '31'iand32 ofthehcarrier .frame. .iEach bolt has the .outer extremity thereof preferably .flattenedupon one side to better adapt it for locking engagement with thecorrespondmg pin or cross-bar 33 within each of'the 1U- cannot be raised.

As. the latter are pivoted at 3413.4 to the carrier frametand as their friction rollers 35, orlike partsaare beyond the bars -:33, when the :bolts are in their outermost positions the'latch elements If the carrier Lbe atthe vrightrhand station as shown in ilTig. 1, .it Lis normally .despatched therefrom .by pulling down upon the ,propellingcord 136, which drives forward the chaseror follower 37 in :a known mannerthrough the instrumentalityof cord 38, pulley'block 39, etc and .the chaser engages thellever .40:at the right hand=end of rthercarrier, toathereby pull outwardly link 41 of said end and swing up the friction -.roller .35 of the :latch out of engagement free, of course, to propel the carrier from the station. When, however, the basket has beenlowered it'has beensfound desirable to a =.provide some means to preventthe despatch ofthe carrier from the station under such eonditions, and in thepatent; toMcOormick,

Number 896,747, dated August 25, 1908, there is shown a device intended for this purpose. It, however, is adapted to act upon the latch element at but oneend of the carrierythis end being of courseathe one at which the basket isr-lowered.

It is desirable under certain conditions, as for example wherethe line+wire does not extend to a'balcony or the like,.to provide i means for lowering thebasket or receptacle at both-ends of the line. If now-suchadeprevent inadvertent despatch o f the carrier from one stationpthere will, in-theabsence of provisions such as are hereinafter -de-V scribed, be:nothing toprevent the despatch of-a carrier o-f'theMcCormick type from the otherrstation, when thebasket' hasbeen lowered thereat, and the present invention aims to {provide a locking means whereby the inadvertent or basketless despatch of the vcarrier from either station is rendered normally substantially impossible. I Let us refer again to Figs.. 2 and 4. Herein,lit will be observed, the right hand bolt r29 has the inner. end thereof shaped for engagement with the camactingvsurit'ace of, the extension 15 of the dog=15, above referred' to, so that ,WllGIl the latter .is raised, bolt:29 1sdrivenoutwardly, while when it islowered, a spring 42 thereon whichlbears 'viceas is shown by "McCormickf be usedto against 1 a collar 43 on' said ibolt return s the bolt to its inner r or .normal position. PA depending extension ofrthis collarserves as a stop to limit-the inwardimovement of said bolt,.as.shown inFig. 1; while afgF OVed rollerrecives the upward thrust lofthein- .nenend .oftheLbolt whenthecam =15 :i-s-actingfthereupon; .The safety .bolt :29 also has secured .1 thereto, as l by "means. of afset-screw,

a collar .44 to which :is attached a bent rod save that it is shorter,- andhaspivotallyiand .45 'which extends out through .a suitable 3 opening in the carrier casing .and thence .runs ;parallel therewith toward -.the bolt 1 30. Theilatteris substantially similar to bolt 29,

slidablylconneeted thereto at '45 a -.forked 1 lever .46, .whichiispivoted at 4:7 to the carrier Qframemr casing :and extends .out therethrough :being connected to the end of the rod 4:5 at A8. By'reason of-this connection between the bolts 29 and 30, when bolt 29 is driven outwardlyns aforesaid, bolt 30 is also moved into locking engagement with the left hand latch member or element 23, r

so that when thedogilo isinitsupper position, which isnormally only whenfthebasket .has been detached from the carrier, both we ail fltlllfi is. ere l1fliaeaiestimag ment and hence it makes no diiference at which station the basket is lowered, its carrier cannot normally be despatched until said basket has been again secured to said carrier.

Having thus described my invention what I claim is 1. Carrier despatch apparatus comprising a track, a station at substantially each end of said track, each of said stations having a latch engaging part, a carrier to ride on said track and having a pivoted latch at each end of said carrier adapted for locking engagement with the corresponding latch engaging part at one of said stations, a receptacle, an automatic lock to connect said receptacle and carrier together, said lock having a part, a determined movement of which disconnects said carrier and receptacle, a plurality of interconnected means to lock both of said pivoted latches against determined movements thereof, and connections between said last mentioned means and said part. 7

2. Carrier despatch apparatus comprising a track, a carrier to ride on said track and having a pivoted latch at each end of said carrier, a receptacle, an automatic lock to connect said receptacle and carrier together, said lock having a part, a determined movement of which disconnects said carrier and receptacle, slidably mounted bolts to lock both of said pivoted latches against determined movement thereof, and connections between said bolts and said part.

3. Wire-line carrier despatch apparatus comprising a track, a station at each end of said track, each of said stations having a latch engaging part, and a carrier having a detachable receptacle, an automatic locking device to alternately connect said receptacle to and release said receptacle'from said carrier, a movably mounted latch at each end of said carrier, each of said latches being adapted for locking engagement with the corresponding latch engaging part at one of said stations, means to hold both of said latches against movement in a determined direction and connections between said last mentioned means and an integral part of said locking device whereby each of said latches is held against said movement thereof when said receptacle is released from said carrier, said connections being carried by said carrier and being separate from the receptacle thereof.

4. The combination of a carrier for wireline apparatus comprising a detachable receptacle, an automatic locking device to alternately connect said receptacle torand release said receptacle from the carrier proper and a latch part pivoted to each end of said carrier, with two latch parts, one at each end of the wire-line and adapted to respectively engage said pivoted latch parts, and means, controlled directly by a part of said locking device, for preventing the inadvertent disengagement of whichever set of said latch parts is in operative engagement, when said locking device is in its receptacle releasing position, said means being carried by said carrier and being separate from the receptacle thereof.

In testimony whereof I have affixed my signature, in the presence of two witnesses.
