ELDRIGE V. MCCULLQCH, 01 ST. LOUIS, MISSOURI.-

asaase. 7

Be it known that I. Erector. V. M CUL- LOCU, a citizen of the United States, residing I at St. Louis. in the State of Missouri, have invented certain new and useful Improvements in Attachments for T raction-Engines; and I do hereby declare the following to be afull, clear. and exact description of the invention, such as will.enableothers skilled in the art to which it apperlains to make and use the same.

{lhisinvcntio'n relates to traction engines .and has special reference to a novel form of 1 hauling attachment for engines of this description. One object of the invention is to provide means of novel character for releasably gearing a winding drum to the traction wheels of an engine of this description so that if the engine strikes muddy or slippery ground it may be enabled to pull itself out while at the same time the traction wheels are revolved. v

\Vith the above and other objects in view, the invention consists of an attachment for traction engines comprising awinding drum omitted.

and certain novel gearing arrangements.

The invention further consists in certain novel details of construction and combinations of arts hereinafter fully described, illustrate( in the accompanying drawings, and specifically set forth in the. claim.

In the accompanying drawings, like charactors of reference indicate like parts in the several views, and :-Figure 1 is a partial side elevation of a traction engine showing the device applied thereto. Fig. 2is a detail perspective view of the device removed from the, engine with a portion of the same The numeral 10 indicates the boiler of a traction engine and on this boiler is mounted the usual driving engine 11. The boiler and engine 11 are supported on tractor wheels 12 to one of \vhichis attached a driving gear 13. 5 i

At 14; is a shaft which 'is suspended in any suitable manner below the boiler and just in front of the fire-box. On this shaft is keyed a pinion I L which constantly meshes with the. gear 13' so that the shaftis rotated whenever the tractor wheels rcvolve, there being suitable connection between one of the wheels and" the engine al though this is not here shown as the same forms nopart'of the invention. Upon the i Specification of Letters Patent.

shaft 14 there als'i'providw'l a second gear 15 which fixed on the shaft in any suitable manner to revolve therewith. boiler and firmly atiaehed thereto is a saddle ing spaced arms 17 each of which has formed at its lower end-a bearing 18, the hearings being alined and adapted to receivethe journal ends of a shaft 19. Secured to this shaft 19 is a drum :20 on which is wound a hauling cable'fll. T here is also provided on the shaft 19 a gear 22 which is, like the drum, securely keyed to the shaft and this shaft further has at the end adjacent the gear an arm 23 pivoted thereon and provided at its outer end with a stub shaft- 2% whcreon is'niounted 'a gear 25. which constantly meshs'with the gear The gears and 15 are in :iiinemcnt and the teeth of the three geais L3. and 25 are of the be caused to mesh aith the gear 15 if the arm 23 be raised. A In order to raise and lower the arm 23 arm has provided near its outer end an upstanding car 26 over which tits the forked i through the forked end and ear to connect the two. Uponthe side of the boiler is a lever 31 one arm of which is connected to the upper end of the' lift rod 2-8 while to the other arm there is connected a reach rod 32 the opposite end of which is connected to a latch lever which is pivoted on a bracket 34, the lever carrying a quadrant 35 wherewith the iatch of the latch lever is engageable. c

In the operation of the device the gears indicated in Fig. 1- If the engine. gets stuck in a mud hole the rope 21 is led off to some convenient position such as a tree and its end there made fast. The latch lever 33 is then moved to the rear and this lifts the aim through the medium of the reachrod, bell crank and lift rod. As the arm 23 is raised

thevgears

25 and 15 are brought into engagement and when the engine is started and the tractor wheels 12 revolved, the gear 13 serves to drive the train of gears formedbr the

gears

14, 15, 25 and 22, thus rotating the shaft 19 and drum 20. As the drum 20 rotates the cable 21 is wound, thereon and materially assists and cause the gears i5 and25 to engage this.

bracket 30 whereon is mounted a bell crank.

15 and 25 are ordinarily out of mesh as Below the i i lilock lfi provided with dowmvanlly extendsame pitch. By this means the gear 25 may 1 acnd 27 of a lift real 28, a pin 29 passing in pulling the engine out of the hole or de-- pression. It is to be observed that the gears in the train and the diameter of the drum are properly proportioned so'that the space traveled over by the wheels 12 will equal the length of ropeor cable 21 wound upon the drum.

There has-thus been provided a simple and efiicient device of the kind described and for the pu1'p0se,speeified.

' Having thus described the inwntion, what is claimed as new, is

A device of the kind described including a shaft, niountedfor rotation, engine actuated means to drive said shaft, a gear fixed on said shaft to revolve therewith, a second 'sha'ft rotatably mounted parallel to the first "mentioned shaft andjn advance thereof, a

drum fixed on said second shaft, a gear 20 fixed on said second shaft, an arm pivoted means including a lift rod con'nected to the arm,a bell crank lever fixed above said. arm and having one arm of the lever connected to the lift rod, a reach rod connected to the other arm of the bell crank lever, a latch lever connected to said reach rod and a quadrant coiiperating with said latch lever.

In testimony whereof, I afi'ix my signature, in presence of two witnesses.
