To all whom it may conccm."

Be it known that I, SAMUEL SQMA THES,

"citizen of the United States of America, re-

siding at lllansfield in the county of'Richland and State of bhio, haveinvented certain new anduseful Improvements inReeling Devices, of which the following is a specification.

My invention relates to improvements in winding devices and has particular reference to the retrieving and resetting mechanism, and I have described its use andoperation as applied to trolley retrievers although its use is not limited to trolley retrievers.

One of the objects of my ,inventionis to provide an improved device of this character which will be simple, durable, reliable, and compact in construction, and effective and efficient in operation.

Another object is to provide a reeling device comprising mechanism dependent upon the winding up of the power spring to a predetermined tension for resetting the device to normal operating condition.

A further object is to provide a reeling device comprising mechanism compelling the winding up of the power spring to a predetermined tension when resetting the device. w w

A still further object is to provide a reeling device comprising a: resetting device and mechanism to cooperate therewith and operable by the power spring when wound up to a predeterminedtension to permit movement of said device into a position where it operates to prevent further winding up of the spring.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the novel features of the design, combination and arrangement of the several parts tohe hereinafter more fully de scribed, and claimed, and shown in the accompanying drawings which illustrate one embodiment of the invention, and in which u a t Figure l is a side view of a winding device embodying my improvements and shown partly in section to illustrate the constructional arrangement of the several parts, as applied to a trolley retriever.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1, and showing the power npole. l i a a .Flg. .45 is a similar view indicating the spring wound up and the setting mechanism in normal operative condition.

Fig. 3 is a sectional view substantially on the line 3-43 ofFig. 1, and showing the retriever disk in interlocked relation with v the caseand the drum free to rotate in either direction under the actlon of the trolley mechanism in the act of unlocking the retriever disk, (dotted lines) and also show- 111g the retriever disk unlocked from the caseand about to commence its retrieving action, (full lines) Figs. 5 and 6 areviews of a ortion of the ease and the retriever disk an showing the interlocking or setting mechanism in vari-l ous positions and which will be referred to hereinafter.

Fig; 7 is a view of a portion of the retriever disk showing the opposite side there 01 than that shown in the other views.

The same reference characters indicate "the same parts throughout the several views.

In the drawings, 1 designates the case of an ordinary retriever and which comprises, as shown, a cover 2 whlch may be removablly l secured thereto'nin any suitable or we known manner. The case is formed with a recess 3 wherein is mounted a power or retrieving spring 4, which has its outerend secured to the case, as by rivets 5, or otherw se. The inner end of this spring 1s connected in any well known or suitable mannerppreferably as shown in Fig. 2, to the hub extension 6 of a driver 7 which is rotatablv mnuntedon the shaft 8 secured within the case. power arm 9 which extends and has a limit ed amount of movement between stops l0 and 11 provided on one side of the retriever member or disk 12 and is constantly "urged to rotatein the direction toward and norr iii-ally held in engagement with, the stop 10 by the tension of the power spring. Tending to rotate the driver in the opposite direction, as toward and into engagement with the stop 11 is a control spring 13 having one end attached to the arm 9 of the driver and its other end adjustably connected to the retriever disk as by means of a screw 14: passing through a lug 15 formed on the disk andhaving threadedengagement with the nut 16 secured in the end of the spring. It

The driver comprises a.

" the stop? end Thus it will be seen that when the'latch is thrown out and the lock screw.14- the spring '13 may be held under will be apparent that by adjusting the any desii'ed or required amount of tension. ivotally secured to the arm 9 as at 17 is a movable member 18 which is constantly urged to rotate toward, and adapted when inoperative position to be held in engagement with, its cooperating stop 19, (see Figs.

s own in Figs. 2 andB, and is constructed arranged so that when it is in operative position its end extends slightly beyond the end of the arm 9, forming an offset or shoulder 21, (see F ig. 5), the purpose of which will be'brought out hereinafter.

1 The retriever member or disk 12 is mounted for rotation in either direction and is adapted to be rotated in one direction by the power spring 4 through themedium of the driver 7 to wind up the trolley rope and thereb pull down the trolley pole, and it is adapted to be rotated in the opposite direction for the purpose of resetting or winding up said spring. This disk is provided with a flange 22 having a suitable slot which is arranged a double latch which is adapted to normally look the retriever disk to the casesoas to prevent its rotation and to hold 't'hepower spring under tension. This latch comprises two levers 28 and 2a which are pivoted at 25 and 26 respectively. The inner 'or'adjacent ends of the levers are knuckle jointed so that they will both move siniulta'neously, the lever 23 at this end being notched while the corresponding end of the lever 24 is formed tooperate in said notch shown in Fig's. 3; to 7 inclusive. When latch is in looking position the free ends 27 and 28 respectively will be projected or thrownbeyond the periphery of the flange on the retriever disk and in position to engagethe'fixed lug'sf29 and 30 which are preferably formed integrally on the inner wall of the case. F or convenience of description I will hereinafter refer to the end 27 of the latch as the lock? end, and the end 28 as end is in engagement with the stop lug 29, the retriever disk will be positively locked against rotation by the spring 3 and in a direction to .wiiidup the trolley rope. The

' operation of the stop end of the latch will be described later. The two levers which COIHPIISGjlllS latch, as is seen, are formed so that when said levers are in inward or re I leased position, as shown in Figs. 5,- 6 and '2",

no portion of them will project in the path the lugs 29 and 30, thus leaving the disk freejtorotate. A coil spring 31 having one end connected to the lever 24 and its other Rotatably mounted, preferably upon another hub extension 32 of the retriever disk I is a drum 83 adapted to receive the trolley rope 34. This drum is formed with a compartment 35 wherein is mounted a service spring 36, which operates to rotate the drum in the direction to keep the trolley rope taut. The outer end of this spring is connected to the d1-umii1ai1y suitable or desirable inanlief while its inner end may be connected to a stationary sleeve 37, which may be mounted for adj iistment by means of ratchet teeth, not shown, or otherwise.

The drum normally follows the movement ofthe trolley pole as the trolley pole and drum are connected by a rope, and in case of an abnormal rapid rise in said pole mechan sm is actuated which will unlock the retriever disk and connect it with the drum so that the drum will be rotated in the direction to wind up the trolley rope and pull down the pole. In order to throw in the latch and release the retriever disk the drum Carries a plurality of centrifugal dogs 38, which are pivotally mounted in suitable sockets or bearings 39, formed in integral bosses on the side of the drum adjacent the retriever disk. When normally operating, these dogs are yieldably maintained in inward or retracted position by springs 4-1. the free ends of the dogs resting against the adjacent bosses, as shown in Fig. 3. T hose dogs are arranged so that they will be sensitive to abnormal rapid fluctuations of the trolley pole, such for instance as when the pole leaves the wire and flies upwardly. liecause of the undue speed of the drum incident to the quickupward movement of the pole the dogs will move outwardly against:

the peripheral flange 22, on the retriever disk under the action of centrifugal force.

It will be noticed that the knuckle joint of the latch, when the latch is in locking position, lies within the flange 22 and hence within the path of the free ends of the tripping or centrifugal dogs 38. In consequence, the tripping dog, which at the instant is the nearest to the knuckle joint of the latch, will strike said joint and force it outwardly, thus throwing the lock and stop ends of the latch inwardly and re lease the retriever disk. In order to insure a positive releasing action on the part of the dogs, I provide an outstanding rib 4-2 on the face of the retriever disk adjacent the centrifugal dogs. This rib is positioned adjacent the knuckle joint of the latch to provide a. comparatively narrow space between the rib and the flange 22. In addition the free ends of the tripping dogs are provided with extensions 43 of suilicientthickness to pass through the channel or space between the IOU riband flange and thereby positively force the knuckle joint of the latch outwardly. For the purposeoi": maintaining the latch in inward or released position during therotation of the disk by the powerspring and during the resettingor wlndmg upoperation of the device to normal operative condi tron, I providelthe lever 23 with an outstanding pinei5,which is normally disposed in the position shown in Fig. 8 andflvhere itoperates to maintain the movable member 18 in inoperative position and out of engagement with its cooperatingstop 19. By movement of the latch into inward or released position, this pin is carried out of the path of the movable member 18 which will then move into engagement with the stop 19ers shown in Fig: 5. In this position of the movable member 18 it will. be noted that'it forms an obstruction inthe path oi the pin 45 and thus positively prevents movement of the latch into outward or operative position prior to the nnwlndlngoft the power springand the resetting or redisk. By thus engaging said shoulder the tripping dog; positively 1l1t61'iOCkS1Jl1Q16-.

triever disk and drum and the latter will thereby be carried with the retriever disk and will wind 1 up the trolley rope.

In order that a clear understanding of invention may be had, abrief statement of the operation is as follows. When the power spring is wound up or set and the parts are in their normal position they will be as represented in Figs. 1, 2 and 3. The latch will bein outward position and the lock end 27 of the lever 23held in engagement with the lock? lug 29 of the case and the movable member 18 held in inoperative position by the pin The arm 9 of the driver T is held in engagement with the stop 10 by the tension of the power spring et and against the action of the control spring 13, and the centriiugaldogs held 1n engagement with the bosses 19 as shown. In th1s relationoi the parts the drum is free to be rotated in a directionto wind up the trolley rope by action of the service springfifi which of sufiicient tension to keep therope taut at all times during the rise and fall of the trolley pole during operation. When the.

rope israpidly unwound from the drum as when thetrolley rope jumps the wire, the sudden impulse or 'apid rotation of. the drum will cansethe dogs 38 to move outwardlyby centrifugalforce and actuate the latch ,to release the retriever disk and then interlock the drum with the disk in the manner heroinbefore described. When this has taken place the relation of the parts "willbe as represented inFigs. 4; and 5. Next the retriever dislcand theldrum, under the influence oi the power spring 4,will be caused to rotate in a rope windingdirection amlwind up the rope and thereby pull down thetrolley pole. As the drum rotates, the power spring, which is normally held under tension slightly higher than that of the con trol'sprinpj 13, weakens whereupon the arm 9 of the driver will be positioned against the stop 11 by action ofthe control spring 13; This positioningoi the arm 9 asis seen 111 1* 1g. 6. carries the movable member 18 out oilithe path oi or alinement with the pin 45 which holds the latch in released position and which is then brought to bear or rest against the end of the arm 9. The parts will remain in this relation during the unwinding of thevpower spring and the consequent winding up of the trolley rope. I i

To set or restore the parts to their normal operative condition after thedevice has operated as above, it is only necessary to pull outon the trolley r0 e thereby unwinding the same and rotating-t 1e drum and the retriever diskin thedirection indicated. by arrows in Y Figs. 5 and 6. lVhile the rope is beingpulled out-and the drumand retriever diskrevolve, winding up the power spring, the arm 9 of the driver is held in engagementwith the a stop 11 by the action of control spring 13 and the latch held in released position by engage ment oi its pin eifiwith the end of the arm 9 until the power spring is wound. up to a point where its tension becomes equal to or balances the tens on of the control spring 18." Then upon continueclrotation oi the parts in the same direction and the consequent iurther tensioning of the power spring, the arm 9 under the influence of this increased tension will movetoward and into l engagement with the stop and against the actionof the controlspring. During this positioning of the arm 9, it willmove out of alinement or engagement with the pin 45,

and the movable member 18 will be brought into engagement with said pin at 21' and shiftedtonormal inoperative position, thus leaving the path of the pin &5 unobstructed whereupon the latch under the influence of its spring 31, will immediately move into outward or operative position as shown in Fig. 2. If at this instant the lateh is not positioned between the stop lugs 29 and 30 it will in the continued rotation of the disk ride over thesurface 4:3 and the lock end of the latch will snap in behind the lock lug '29 in position'to prevent or look therevtriever disk against rotation in the retrieving direction as above'described. This snapping in of the latch does not indicate to the conductor that thelatchis in locking position and the. operator continues pulling out on' tlie rope until the stop end 28'of the latch strikes the stop lug 30 of thecasing.

This action positively prevents the further winding'up of thespring and indicates to the operator that the latch is in locking position. As soon then as the pull on the trolley rope is released, thedisk will move in the reverse direction until the lock end 27 of thelatch is brought into engagement with the ""lock lug 29 of the casing and locks the disk against rotation until it is again released by thecent'ritugal dogs 38. It now remains to unlock the drum from the retriever'disk, which it will be remembered I were held'interlocked While the parts were being. restored to normal operative cond1- tion. v This is accomplished as soon as the pull on the trolley, pole is released, where upon the drum will start to rotate in the oppositedirection by the'action, of the service spring 36, and in so doing it carries the centrifugal dog. 38 out of engagement with the stopshoulder 42 of the disk. The dog moves out until-it passes the end of the guide rib l6 and it is then drawn inwardly against the boss 40 by its spring ll, thus finally unlocking the drum from the disk and leaving the drum ireeto again normally fwind up and unwind the trolley rope. 1

ItW- ll be evident from the roregoing-that the mechanism which operates to automativcallyrestore the latch to locking position is controlled bythe tension of the control spring 13 and that by varying this tension,

:as herein provided, the device may be adjusted to obtain any desired or required amount of retrieving action.

Having thus fully described my invention and illustrated one embodiment of the same,

I do not Wishto be limited to the details of the construction-shown since these can obviously be changed without departing from the spirit and scope of the invention.
