To alt whom it may concern;

Be it known that I, JULIAN L. PEnKiNs, a citizen of in the county of Harnpden and State of Massachusetts, have invented new end-useful Improvements in Trolley Catchers and Retrievers, of which the following is it specification.

This invention relates to trolley-catchers and retrievers for automatically preventing the trolley-head or pole from injurin the net-work of overhead wires when the trolley-wheel jumps the wire and is suddenly thrown upward by the expensive force of the spring on the car which controls the trolley-pole; and its object is to provide a construction which will permit the trolley-pole to iollow any unevenness of the trolley-wire or movements of the car, and at the some time if the pole should accidentally leave the wire to quickly rotrieve or draw the some back before any injury would be done to the overhead wire construction.

A further object is to provide a construction whereby one spring will allow the trolley-rope to work freely up and down with the movement of the pole, and if the trolley-wheel should accidentally leave the wire to bring into operation a stronger spring that will instantly draw the pole back again below the horizontal plane of the overhead wires.

A still further object is to provide an automatic catch or stop that will. when the trolley-catcher and retriever are placed in position on the car, release thev winding-drum so that the trolloy-ropc will freely ioll low the movements of the pole and will automatically lock the drum against rotation when the winding and retrieving device is removed from the our in order to prevent the drum from winding the rope-onto the same and iillowing the device to lly up against the hand of the conductor. This automatic cntcli also locks the dc- Vice in place on the czir as (lescribcd in dclnil below.

In the accompanying drawings forming port of this application, Figure 1 is a sectional side clcvution of the catchment] rctricvcr on line .ll Fig. 2, with the closiug cap rcn'iovod and showing the automatic lock for the winding-drum or barrel which contains tlicstrongcr sprin Fig. 2 is a vertical section on the lino 2 2 of Fig. 1.

45 word into locking engagement I1, is a spring barrel 4 composed ol :1. cup or (T-shaped part 5 and A plute 6, the latter being secured to the cup or (l-shaped part 5 by the screws 7 (see Fig. 3).

On the inner surfzu'e ol' the rope \viiuling-druni e are 5 out a series oi inclined holding mtchets 8 which, nor- ,rn-.illy,-whon the trolleyro nplays lrecl y up and down in unison with the movement of the our lightly strike the S-shzrped locking-pawl 9 on the upturned end, 10 thoreoi, The pawl f) is pivotally moui'rted in the spring A strong spring 13 within the barrel 4 has its bent in nor end nttaehedto the bolt or stud h by means of a slot 1 1 in the. outer end of the stud it while its outer end is Attached to the barrel 1 byii pinor stud 15 This spring onger than the spring n.

Pivolully cured on the outer lane of the havri'l 4 is it puwl or trigger it to which is pivotally secured a spring-retained piece 17: by means of the pivot 18 and spring 1.). This piece 17, {XS shown, stands nearly at 20 right angles to the pawl '16 which is piviinlly secured to the barrel 4 by u pin 20. The spring-retained piece 17 has an (werluinging lip 21 to engage the edge 22 oi the barrel. The S-shnped pawl carries integral with it :1 lug Figs. 4, l3, 7 and 8) which works in cut-out opening :23 (see Fig. 3) of the bar-- ml 4. The upper curved surface of the lug 23 is adapted to engage the overhanging lip 21 at point 24 (see Fig. 4) when the pawl 9 is thrown upward into Eligitglnfillt w th one of the mtchets 8 on the windingdruiu 0 (see Fig. 7). This lug, by its engagement with tho part 24, retains the parts 16 and 17 in the elevated position shown. i

Normally, when the trolley-rope plays freely up d down the pawl lion in the pouition shown in Fig. 6, the upturned port 10 thereof beinglightly struck by tho'end of the rotohets 8 on the rotating drum 0 but not hard enough to throw the end 9 of the pawl ll into engagement with the rii'tehets 8. However, should the trolleyhead accidentally leave the wire, thirst-aiming the drum 0 torotztte much faster than its normal speed, the upturned part 10 of the pawl 9 would receive asharp, qnic c blow from the mtchots 8 on the rotating drum causing the pawl 9 to be instantly thrown upwitli the littChQtS 8, as clearly shown. in Fig. 7; the 1115523 will at the some time come into engagement with thespring-rotained piece 17 on the overhanging lip bl atithe point 24. When the parts are in this position, the tension of the strong spring 13 within the barrel it is thrown onto the winding-drum 0 giving it a quick {rotary movement in the direction opposite to that whom" the trolley-wheel leaves the wire and'witli the tension of the comynrotivcly Weak spring n w'hieh controls tho windingdrum o, The barrel 4 and the drumo lining thus locked together make one or more complete revolutions in. the

opposite diretion with the parts in position, sis shown in Fig. 7, thus instantly drawing the trolley rope back before the pole can strike any of the overhead WllG-B.

In practice, the barrel 4 is wound up so that the drum 0 makes four complete revolutions in the opposite dimotion to draw in the trolley rope.

It will be noticed that mleckingdug 25 isintogra-l with the pawl 16, This lug, in its normal position,

when. the car is running, rests in the notch .26 of u.

holdinglisk 27 which is seizured to the bolt or stud ii by means of a. washer 28 and a st-screw 29, and prevented from rotating by two holes 27 hall of which is in the disk 2'7, as shown in Fig. 3. A pin is inserted in this hole 27 to lock the disk 27 to the bolt 71.

After the parts have been thrown into the position shown in Fig. 7, the pawl 16 and the spring-retained piece 17 remain in the position as shown in Fig. 7, and as the barre 1;. rotated one or more revolutions in the reverse direction in order to draw in the trolleyrope, the lug 25 on the pawl 16 is held from engaging the outer surface 30 of the holding washer 28 on ac: count of the lug 23 being in engagement with thopart. 24 and rot-tins the some in this position until one or more revolutions in the reverse diroetion'are com pleted, depending upon the amount the spring 13 is wound, when it drops by gravity into contact with the outer surface 30 of the holding disk 27; then the slioulders 31 on the rear of the ratchet teeth 8 engage the inclined surfaoo 32 on the rear side of the pawl 9 iorc ing the pawl 9 downward against the tension of the spring 19, whioh connects the parts 16 and 17. During this operation the lug 23 on the pawl 9 passes by the temporary holding point 24. on the lip 21 on the piece 17. Y

The length of the pawl 9 and the distance between the holding rate-hots 8 on the drum 0 is such that in the normal up and down operation of the trolley-r0 .9, the pawl 9 will have time to he forced back below the ratchets 8, without being caught, by the light spring 33. This spring has one end attached to the lug 23 and its opposite and to a stud or screw 33, while its middle portion is coiled one or more times around the pin 35, as clearly shown in Fig. 8. It is to he understood that this spring 33 normally koepstho S-shnped locking-pawl 9 in thoposition shown in Fig. 5 but permitting the mtehets 8 to lightly strike the and 10 without looking the some to the drum 0. When n sudden upward movement of the polo'oceun; the pawl 9 becomes locked with the first holding rhtehot 8. The opening 23 prevents the lug 23 from rising only a certain distonee, the lip 21 allowing the lug 23 to pass when the parts are locked together. The spring 33 in the oar-rel 4 draws the'rops in until the log 25 drops into contact with the disk 27; the partlfi falling by gravity. The amount that the spring in the barrel 4 draws the rope in below the trolley-wire depends upon thedegree of. tension plzieed thereon by the conduetor, as stated below.

In the opomtion of the device, the trol'leyro pe p pluys freely up and down nccording'to the movements of the troliey-pole, the spring "/2. riot being strong enough to pull the trolley-hood 0i wheel off from the overhead wi a, but should ii sudden upward rnov "merit of the trolley-pole occur, when it suddenly leaves the overhead wire, the upturned port 10 oi the lockingpowl 9 will be given 0. sudden blow and instantly the free end of the s-dhaped locking pawl 9 will be thrown upward int-0 the path of the ratchets 8, as shown in Figs. 5, 7, and 8, thus locking together the spring-l arrel 4 and the windingrlrum 0, whereby the snring 13 immediately exerts its expansive iorcltogether with thotof the weaker spring in, to draw inthe ropo 32. It is to be understood that the spring 13in wounchor placed under tension ,hofoze the cor starts or whenever film trolley-WIT 0m relating the lmrrcl 1 bask (ls by the lug engaging lzlie notch 26 iii 0 disk 21 At the. moment that the locking-pawl 9 is tinwwu into l0; i ag'cnlcut with ilic lfliffllill 8, lbs lug lean; 'uoich 2G, and the pawl .l with its lug 23 thereon passes by the lip Zl ol the piew 17. The arts re muin inlthis position until the spring barrel 4 -nnlces one or more revolutions in the direction opposite to that given to it by the trolley pole flying above for waving in the llOllQ/JOZEQ p, and at the end of one or more revolutions, auvorlliug in the number of tinlps that this sp ing 13 Wound up by the cunductor- The part 16, at Sue and of one or more revolutions, drops back by layit into Contact with the outer surface 30 of the holding disk 27. It. is to be undeistoocl shat; at this point the spring 13 has bemmn so noun-1y unwound that the part 16 Q5221 drop back by gravity into the nolclrlZfi. The inclined shquldfi'sill on the lil llfileiii 8 than the part. 32 ol the pawl 9 :mdthe lug 23 isforced against the overhanging lip 21 and snaps the locking-pawl 9 against the t ensinu of the spring 19 back into its inilinl pnsimon, as shown clearly in Figs. 3 and. 4. This ogiemtion is accomplished by the springn revol /ing the (in: l 0 in the normal dire; lion, lhafi is to wind the mp0 3) onto H10 drum 0. Jilin this operation orcurs, the conductor grasps the trolleyrcpe drawing in upward one or more revolul-imls for the purpose of i e-Winding the spring 15, until ll'lelug 25 (ll-ops into the notch 26; the llrolley-ropu is i lmri free is work up and down against the tension of the weaker spring 11 thus 'p rxnitting the bonrlurtor in again place tho trolley-head in position on the ovm'lmad wiro Wlwu llie device is again ready for mwllavr sorir-s oi oporzrlions.
