TOWING-MACHINE.
To all whom it may concern Be it known that I, ROBERT S. RILEY, a citizen of the United States, and a resident of Providence, Providence county, Rhode Island, have invented certain Improvements in Towing-Machines, of which the following is a specification.
This invention relates to that particular class of machines designed to control the winding or delivery of rope or hawser on the drum of a towing machine or similar device; one object of said invention being to provide improved automatic valve controlling mechanism for the engine employed on such a machine.
Another object of the invention is to provide novel means of simplified and substantial construction whereby under certain conditions it shall be possible to operate the regulating valve by hand without requiring a by-pass as has hitherto been considered necessary.
I further desire to provide a novel and simplified combination of parts for operating the device for shifting the rope guiding carriage.
These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which Figure l, is a rear elevation of a towing machine showing my invention as applied thereto; Fig. 2, is a vertical section on a larger scale than Fig. 1, illustrating in detail the construction of certain of the parts constituting my invention; Fig. 3, is a vertical section illustrating the detail construc tion of the pawl shown in Fig. 2, and Fig. 4:, is a fragmentary elevation of a detail of the pawl guide.
In Fig. 1 of the above drawings, 1 repre sents the frame of a towing machine of the well known form and I have illustrated so much of this machine as is necessary to properly locate the elements constituting my invention. On this supporting frame are mounted two engine cylinders 2, whose crank shaft (not shown) act-uates a gear 3 operatively connected to a winding drum 4.
A plurality of guide bars 5 extend between the two vertical portions of the frame 1 and serve as the support for a transversely movable carriage 6 carrying vertically placed guide rollers 7 and a guide pulley Specification of Letters Patent.
Application filed November 19, 1910.

Serial No. 593,157.
8. This carriage is laterally moved by means of a screw 9, to one end of which is connected a gear (not shown) which meshes with a pinion 11 hereafter referred to. The casing of the steam controlling valve for the engine cylinders 2 is illustrated at 12 and said valve is operated through the medium of a valve rod 13 whose outer end is connected to a swivel 14. This latter is made in the form of an open rectangle and while being connected to the valve rod 13 so as to revolve freely independently thereof, has non-revolubly fixed in its opposite end an elongated screw 15.
A pawl 16 slides longitudinally upon the two opposite side members of the swivel, and as shown in Fig. 3, consists of a block capable of a limited vertical movement on said side members. The lower base or edge of this block is slotted as indicated at 17 to form two jaws for the reception of a guide rib 18 on a portion of the frame casting or other suitable structure, and having at its ends two oppositely beveled portions 21 and 22 at the lower edge of the pawl 16 adjacent the slot 17. As a result of this construction the swivel 14L may be moved longitudinally with its pawl 16 in engagement with the guide rib 18 and is held by said rib from rotating until said pawl strikes either of the beveled ends 19 and 20 of said rib. The inclined surfaces of these latter cause the pawl to rise sufficiently to permit of it, with the swivel, to be turned in one direction, although if the direction of revolution be reversed said pawl is held from turning as before. It is, of course, immaterial whether the pawl be provided with two jaws straddling a single guide rib or whether it be in the form of a single projecting piece operating between two ribs.
The screw 15 extends into the threaded end of an elongated sleeve 23 rotatably mounted in a second sleeve 24: carried in a suitable bearing of the main frame. Said screw 15 has fixed to it two stop nuts or abutments 25 and 26, of which the former is designed to engage a shoulder within the sleeve 23 and the latter is placed to engage the end of said sleeve; the distance between these nuts being substantially equal to the maximum permissible travel of the regulating valve for the steam engine. The guide 18 has a length equal to the allowable travel of the valve, so that by the time the pawl 16 reaches one of the inclined portions of said guide, one of the nuts 25 or 26 strikes its cooperating abutment or shoulder.
The outer end of the sleeve 23 has slidably keyed or feathered to it a sleeve 27 carrying an operating handle 28 and provided with teeth 29 capable of co-acting with the teeth 30 on the sleeve 24 to rotatably couple it to said sleeve 27. The sleeve 24 has keyed or otherwise fixed to it a pinion 11, as well as a beveled gear 31, and this latter meshes with the second beveled gear 32, which is directly geared to the shaft of the winding drum 4 and gear 3 in the ordinary manner.
The casing 33 for the structure surrounding the aforesaid apparatus and particularly the beveled gears 31 and 32, has pivoted to it a locking pawl or latch 34, designed to enter any one of the grooves 35, 36 or 37 formed in the sleeve 27 for the purpose of preventing longitudinal movement thereof, there being a collar 38 between the grooves 36 and 37, provided with teeth which are so designed as to prevent revolution of the sleeve 27 when engaged by said pawl 34.
WVit-h the above described arrangement of parts the turning of the beveled pinion 32 when the drum 4 is turned, as by the drawing therefrom of a length of the cable or hawser, causes turning of the beveled pinion 31 of the sleeve 24. Inasmuch as the pinion 11 is keyed to said sleeve, it operates directly through the gear 10 to turn the screw 9 and shift the carriage 6 toan extent proportional to the amount of cable delivered from or fed to it.
If the sleeve 27 be in such position that the teeth 29 and 30 are in engagement, said sleeve with the sleeve 23 is also turned, and inasmuch as under normal conditions the swivel 14 is in such position that its pawl 16 is at or near the center of the guide 18, the screw 15 is moved longitudinally by such a revolution, although the swivel is prevented from rotating by the engagement of said pawl with the guide. As a consequence the valve rod 13 is moved longitudinally and steam is admitted to or cut off from the engine cylinders, with the result that the drum is turned in the well known manner to wind up or pay out the rope thus turning the beveled pinion 32 in a direction opposite that above assumed so as to shortly return the valve to its normal position. If, however, the primary turning of the drum and hence that of the beveled pinions 32 and 31, be continued for a sufficient length of time, the screw 15 is moved longitudinally to such an extent that the pawl 16 comes opposite the inclined portion 20, for example, of the guide 18. Thereafter, owing to the engagement of the stop nut 25 with its co-acting shoulder, any further revolution of the sleeve 23 causes revolution of the swivel 14 and pawl 16, since the inclined portion above referred to causes said pawl to rise on its support-ing guides formed by the sides of the swivel. As a consequence, the valve rod 13 will be moved to its maximum allowable extent and is then retained in this position without the possibility of causing overtravel of the valve, under which conditions the engines are free to operate to cause a reverse revolution of the drum 4 as soon as this is permitted by the rope or hawser. At the beginning of such reverse operation the inclined outside edge of one of the jaws of the pawl 16 strikes the straight side of the end of the guide 18, causing the pawl to rise, and thereafter the inside edge of the other pawl jaw strikes said side of the guide, whereby further revolution of the pawl is prevented, so that the screw 15 is again caused to travel longitudinally in the sleeve 23, thereby moving the valve, through the rod 13, back to its normal position. If this revolution is continued sufiiciently far, the stop nut 26 strikes the end of the sleeve 23, and the pawl 16, upon reaching the part 19 of the guide 18, is again permitted to turn without causing overtravel of the valve.
A reversal of the direction of movement of the sleeve 23 will as before cause the swivel with the valve to return to their normal positions. The locking pawl 34, being placed in the groove 35, effectually prevents longitudinal movement of the sleeve 27 and consequent uncoupling of the sleeves 29 and 30, but if at any time it be desired to separate these members so as to operate the steam valve by hand independently of the automatic mechanism heretofore described, the sleeve 27 is moved outwardly and the pawl 34 is caused to enter the groove 37, under which conditions the teeth 29 and 30 are disengaged. The handle 28 may now be turned and inasmuch as the sleeve 27 is keyed to the sleeve 23, this latter is caused to act upon the screw 15 to move it longitudinally as described, with the result that the steam valve may be opened, closed or adjusted to any desired extent.
If it be desired to provide against the movement of the hand wheel owing to the friction between the sleeves 23 and 24, the sleeve 27 may be moved to such a position that the tongue of the pawl 34 will enter the groove 36, while its tooth will engage with the teeth of the wheel 38 and thereby effectually prevent turning of said sleeve.
