' The vertical 'sha t 21 and its beveled gear. are disposed. normally intermediate the windin and unwinding gears 18 and 19, respective y, andthese two elements are caused to assume this intermediate. position automaticall regardless of whether the car 20 of the shaft 21 be in mesh with eit er. the winding or the unwinding gear. Therefore, assuming that the vertical shaft 21 and the gear '20 are in their normal intermediate p'0 'sition, and it is desired to wind the energy 5 ring; the bar 6 is moved longitudinally to t e left by throwing theoperating lever 25 to the left from itsnormal or full line posi tion (Fi 1), causin the gearf' 20 of the vertical'sha '21 to be t rown from its normal osition between the winding and unwind-- lnggears 18 and 19, respectivel ,Jinto mesh withthe winding gear 18, which atter, owing to the operation of the drive shaft, causes"- 27 to. wind u'ponthe'vertical shaft j the s ring 21. i v'h'en the'gear 20 and its shaft '21 are thus thrown, the pawl 29 on the slidable' bearin 9 is moved upon itsp'ivotbiy.

Tov start-themotor, subsequent to the winding up of the ower spring, the lever 25' is thrown tot e right, (Fig. 1), causing the gear 20 to be thrown intomesh with .the un winding gear 19 on the drive shaft 17, re-

sulting in an unwinding of the spring 27 fee which acts to start themotor.

To effect the aforesaid automatic shifting ofthe vertical-shaft 21 and its gear 20 'toits normal-intermediate position, I provide the aforesaid slidahlebearings 9, 15 and 16'.

These bearings will" remain normally in their initial position; that is at the inner. end of their respective guide-slots, unless the energy spring be wound beyond a certain decontact gree of tension If the spring 27 is wound eyond its normal highest tension, the ar 20 on the vertical shaft 21 will be ued tion of the 'sprin 27 upon, the windin shaft 21 causinga sli mg movement of sai bearings, and by virtue of which the tension of the power s ring is released prior to its ing ispulled out of its normal position iii-its guide-way against the action of said spring pressed pawlsand the spring 40, the pawls bearings is eventually overcome. to" the extent of permitting. the slidable bearings to the vertical sha;ft *21 and the gear: 20-t'o'a; position intermediate the windingandung automatically out otfoperative relation with "tudinally mo abl name and withoutvany; attention; on the. part; of a the operator of the;

load of tension incident to the unwinding operation and prior to a complete unwind, ing thereohthe springs 40 would automatically shiftthe' vertical shaft 21 and its gear 20 to their normal intermediatejposition.

that when the correspond ng slidablelbear- 33 ofthe res ective'g'uide ways will resist movement o the corresponding slidablebearings; 1 This resistance byfthe slidable ,Z move longitudinally in their. guides'to shift ioo winding gears; Thus the gear ,20 is thrown the winding gear without'shifti-ngthe 1ongi= the gear 20 of the -'vertical shaft 21 into spring would be quickly relieved of its over- When tlieen'ergy spring is utilized to start will return to their normal positions without shifting the longitudinally movableframe so as to dispose the gear in its normal in termediate position automatically, although this automatic shifting ofthe gear 20 to its normal intermediate position out of engagement with the unwinding gear will not take place until the power spring has lost practically, if not all, of its tension, incident to its unwinding.

There is an enlongated arm 39 on the standard 2 whose free end is adapted to engagethe aforesaid pawl 29 if the bearing 9 reaches the outer end of its guide-way, or when the frame is shifted to throw the intermediategear into mesh with the unwinding gear, merely' for the purpose of throwing said pawl 29 away from the teeth of the ratchet 31 to obviate unnecessary wear upon the teeth of the ratchet. A bracket 41 secured to the bar 6 aids in supporting said arm 39.

In Fig. 6 I illustrate a modified form of means for controlling the movement of the slidable bearings, consisting in the pivoted pawls ll and 42 engaged by the spring 43 and eke-respectively, the latter pawls and springs being mounted in the sockets 45 of the 'guideways, as shown. This isan obvious *ariation of the form of spring pressed pawls, as compared to the first described spring pressed paw ls, and illustration other than that shown in Fig. 6 seemsentirely unnecessary.
