-the United States, residingat Franklin, in the county of Venango and State of yYennsylvania, Ahave invented that it may be readily operated by either hand or' horse power and conveniently moved from place to place. f'lhe invention contemplates the construction oi a pulling machine or hoisting apparatus oi such construetion'thatwlien in use it' will provide a tall mast over a sheave at the upper end of which the hoisting cable passes from a drum in the supporting frame or base, so

- .mast is 'adapted to collapse or telescope seas to reduce its length jor convenience in moving the machine from 4 place to place on a truck or carriage which is adapted to be attachred thereto- In the following specifications I have entered into a detail description'o the construction, operation and practical advantages oi my invention, -and what I claim as new and desire to secure by Letters-Patent is more speciiically set iorth in, the appended claims.

' In the accompanying, drawings, which forni a lpart l of this specificationzf-lfigure l is an end elevatio'n oi a pulling machine constructed in accordance Awith my invention, and showing the upper section oi the mast lowered or telescoped within the lower section.' Fig. 2

is aseetional view'of the machine, slightly reducedl in size, 'andshowing'the mastextended to its iull length.

`Fig.,3-.'is an enlarged detail sectional View through lthe A upper part of the lower section'oi the mast, to show 7 is a detail view of the truck. Fig; 8 is a view showing -mpdicatio'n of the lneansior supporting the upper the, application oi the brake for the operating drums and shaft.l Fig. 9is a'detail sectional view showing a section of the mast.

; Like numerals of reference indicate like lparts in all the figures'of the drawings. i Though my improved pullingA machine., hereinafter. particularly describedfis designedV especially for pulling out tubes and rods from Artcsian and oil wells, as shown in the drawings, it will be obvious, however, that the said machine may be employed for all kinds of pulling or hoisting work where a tall mast or upright is desired so that the article or material to `which the cable is attached may be elevated to a considerable distance above the ground orplatiorm upon which the machine is placed, and in which the machine is required to be moved from place to place.

ln 'carrying out my invention l provide in the first instance a supporting irame which is -strongly built and comprises the two sill pieces l l., the opposite side pieces or standards 2 2, and the upper crosspiece or platform fi, the latter being rigidly secured between the upper ends oi the side pieces or standards.

`'l.`wo sill pieces are -proferably employed', and the side pieces or standards are cut away to receive the Y same shown at 1 in Fig. o, and are bolted lo said. sidepi'eees by means oi long bolts 1, said bolts extending through the sill pieces and through the portions 2iof the side pieces, as'illustrated in Fig'. 4 of the drawings. This frame is braced by means ol metal pieces or standards, and -in addition to bracing the structure also provide"bearingsA for .the operating ing-rarneis the lower section 5 oi the upright or mast,

the lower end 'oi said section being providedwith 4a vreiniorei'ng collar 6 having a wide buse-[lange 7K bywhich' it is securely stepped and bolted upon the frame. This section 5 is a metal tube, and may loe either round or polygonal in cross-section, and is preferably of the Same diameter throughout its length. The upper end oi the section 5 has secured, thereon a collar 8 providedwith perforated ears l'to receiv'e the guy-ropes 10, and with lrackets ll in which are journaled grooved rollers or pulleys l2, the purpose ol which will .be hereinaiter explained.

Suitably mounted within the tubularsection 5 of the mast is an extension see-tion 13, lthe lower end portion oiwliich is adapted to [it closelywitliin said section 5, while the upper portion thereof is preferably tapered and at its upper end has secured therein a Acasting lll shaped to form a housing 15 lor a grooved tor the guy-'ropes 18, The lower end oi this casting 14v is tapered or conical-shaped, so that when the section -13 is lowered into .the section l5 said casting will [it tightly therein. i i

To provide for raising and lowering the extensionsection 13 it is provided at its lower end with a crossbar 19, the ends of whichfproject throughvertical 4plates 4, which are secured to the ysides of the'side bar are ropes 21, which pass upward and over theslots '20 in the tubular upright or lower mast section 5, and connected to the projecting ends of said crossguidefpulleys 12 and are brought downward. for conynection to a spreader-bar 22. To the spreader-bar is also attached a'rope' 23, which `passes downward andl 26, 'and -is provided at one side. with a hub 27 whichy passes through the .adjoining standard 2 and is prosv vided at its outer end with-a gearwheel 28 connected .thereto by alkey 29.' The gearwheol 28 is in mesh with a pinionBO, and to the -latteris attached a cranklhandle31,1-sai'd pinion` being suitably journaled in a bearing attached tothesupportingtrame. However,

vinstead-ol employing a pinion, as shown, I may in .some instances attach the crank-handle directly to the gearwheel 28, and this may be done where it is desired lto more rapidly turnthe drum; but where greater power-is required inturning the drum the pinion will2 ot course, be used.

One ot' the heads of the drum 25 may be formed into a ratchetfwheel 32, while the other head forms a brake-wheel and is engaged .by a brake-shoe 6l (Fig. 8), saidv brake shoe being carried by a lever (i0 having a socket in which is placed a. removable handle G2. The ratchetwheel 32 is engaged by'a pawl, to prevent backward rotation of said drum, and more particularly when it is'employed for raising the upper section ol the mast, it being understood that lor this purpose the drum may be'turned independent of the larger drum .or bull-wheel hereinafter described. Upon the shaft 2G is also mounted a large drum or bull-wheel 34, -which is connected to turn with said shalt by means of a key'35, 'and the shaft extends through the hub of the drum 25 and is provided with a key-way adapted to register` with a siinilar'keyway in said hub, and so that the said shaft and hub may be' connected together by the/insertion of a key. The lmisting and; lowering cable 3G .passes from the drum or bull-wheel 34 up and over the sheave 16 at the top of the mast, and tothe end of said cable is attached ahook 37 by which it is connected to a suitable gi'ap}' ling deviee. However, the' end 0f the cable may be provided with any other device lor connecting it: td the tube, rod or other object it is desired to pull upon. In the present instance the machine is shown as employed l'orvpulling a rod,.as 38, rom an oil well tube 39, and there is employed an linterposedv yoke-har 40, which is Vconnected tothe rod and ispr'o? vided at its'upper end with an eye with' which the .aforesaid hook 37 engages, asv shown in FvigrZ of the drawings'.

able form' of catch, lfor instance 'asshowrrin- Figsr and A9. 'In the torni shown, irl-Fig'. 3 the' cross-baril!) is contrposed of two plates which normally lie side by side and are provided at their outer ends Wi th alining apertures by which the' ropes 2l are attached thereto, and which ropes tend to `hold the plates together. These plates are seated in oppositely beveled recesses in the lower L end 'of the section 13, and are adapted to be spreadl apart at their lower edges so as to engage into notches 4l at opposite sides of the slot 20 near the upper end of f the latter. The lower walls of said notches are bev'-v eled to'ieceive the correspondingly beveled edges of the platesand so that the'latter will be held securely therein when the weight of the upper section 13 of the .Y mast is uponthe cross-bars or plates 19. For the plurpose of spreadingrthe plates at. their lower;o dges, to

thereby insure their engagement with the uotcheasaid plates are connected to a pull-cord 42, the. branched upper end of which passes through apertures in'the lower end of the mast'sccti'on 13, while tho cord extends down through the lowermast section 5 and out through the slot 20 therein. The upward movement will be readily understood by reference to Fig-3.0i the drawings, for theuppermast sectionl being` raised by the ropes 2l and their operating means until theplatesp 19 abut aga-inst the upper end o the slot o r lower edgev of the collar 8, the cord 42 'is then dra separate the lower edges of` the cross-bars, 1' plates 19 I so that they will engage into the notches when the said upper mast section is lowered a short distance. Whenit is desired\to lower the upper mast-section into the lower mast scctionv, to the positionshown in Fig. l of v the drawings, 'the ropes 21 are drawn upon to` firstA lift said upper'scction until the eross-bars or plates dis-l engagel the notches, andthe said cross-bars or plates being drawn together by .the-connection of the ropes 2l therewith the said cross-bars or plates will then be con-v4 l fined to theslot20 when the section 13 is lowered.

In Fig. 9 I have illustrated another device forsup-. port-ing the upperzsectionl in its extended position, 'and' in this form a pivoted latch-bar 70 operates inl opposite slots 72 and 72IL in the lower mast section 5,

and to'said-pivoted latch-bar is attached a pull-cord ,7l for operating the same. In vthe'operationoi lthis form ol supporting means the section .13 of the mast isV first raised to the limit of its upward movement and the latch-harm is then ypermitted to swing. down' until it extends across the lower section 5,resting at the base ofthe sl0ts72 and 72". The mast section 13' is then lowerml until the cross-bar 19 rests upon said latch bar andso thatthe section will be supported by thelatter; I

In lowering 'th'eupper-section itis first raised untill itis out'otthe path of the plvoted latch-bar, andthe latter is then swung upward solasA to' be out of the path osaijd-fj` section. f` t
