" Wild and imperiling life and property.

The invention relates to means for securing these levers so that they cannot be released yor tampered with by unauthorized persons;

and it has for its object the provision of improved means for accomplishing this purpose, as will be hereinafter described.

In the accompanying drawings, in which like numerals designate similar parts throughout the several views, Figure 1 is a side elevation, on a reduced scale, of a controlling or reversing lever with this invention in place thereon, showing a connection leading to the usual link-motion. Fig. 2 is an enlarged view similar to Fig. 1, a part of the reversing-lever being broken away., Fig. 3 is a longitudinal` vertical section on line 3 3, Fig. 2, of my combined reversing-lever and lock. Fig. 4 is a horizontal section on vline Qc, Fig. 2, looking in the direction of the arrow.A Fig. 5 is a horizontal section of the lock, taken on line y y, Fig. 2, showing the key and spring-actuated pins in elevation. Fig. 6 is a front elevation of a part of the body of the reversing-lever, the cover and its attached parts being removed. Figs. 7 and 8 are respectively side and plan views of the casingV for the barrel of the lock and its connected extension and cover. Fig. 9 is a plan view of the bolt. Figs. 10 and 11 are respectively side and end views of the barrel or plug of the lock. Fig. 12 is a perspective view of a headed pin, the purpose of which will be hereinafter explained. Fig. 13 is a side view of a notched gear employed in my improved lock. Fig; 14 is a side view of a modiiication; and Fig. 15 is a partial section of said modification, showing a key retained in the lock.

Reference being had to the drayvings, the numeral 5 designates in a general way a reversing-lever, comprising an enlarged body portion 6 and a projecting shank 7 of less diameter than said body portion. Upon this shank is sleeved a handle 8, fitted for slight downward movement against the pressure of a spring 9,and this handle is provided adjacent to its lower end with laterally-projecting studs 8 82, the former of which engages alockin g-seat of any desired kind (shown as a notch 10) of a bar 10 when the reversing-lever is in a vertical position, as shown in Fig. 2, constituring a latch which locks said lever against movement until said pin is released bya slight longitudinal movement of the handle against the stress of the spring 9. This reversinglever is usually mounted for swinging movement and may be connected with a link-motion or athrottle-valve by a rod 11 (see Fig. 1) or other means. I In the enlarged body portion 6 of the lever a perforation is made at6, and sockets or recesses 62 62 are also formed therein for reasons hereinafter stated. Designated by the nume`ral12 is the plug or barrel of a lock,which is longitudinally slotted at 12to receive a key 13, and this barrel is also provided with a series of recesses 122 to receive the spring-actuated pins hereinafter described, with a toothed surface 122, an eccentric 124, and a stud 125, by which the barrel is journaled in a cover 16.

Surrounding the barrel -12 is a casing 15, having a lateral extension 15', preferably integral therewith, carrying the plate 16 for covering the recessed and perforated body portion-6 of the lever and securing the barrel, its casing, and connected parts thereto.

Pins 17,normallypressed inward by springs 1S, are located in perforations 152, passing through the extension 15', and these pins by entering the recesses 122 in the barrel 12 lock said barrel against movement. Other pins 17 are located in the recesses 122 of the barrel 12, such pins 17 being so proportioned in length that when they are thrust outward by the insertion of the key 13 in the slot l2 in linewith the pins 17 the latter will be thrust back until their ends clear the barrel, thereby permitting the barrel to be rotated.

Threaded at its extremity into the end Wall of the recess 63 isa bolt 19, having areduced portion 19', on which a gear-wheel 20, havn ing a locking-seat 20 in its peripheryand in engagement with the toothed surface 123 of the barrel 12, is mounted, and surrounding the enlarged barrel of the bolt is a torsionspring 21, secured at one end to the bolt andV at the other to the gear-wheel, the tendency of the spring being to rotate the gear-wheel when such action is permitted, as will be hereinafter explained.

`Fitted in a slot 22 in the front wall o f the body portion 6 is a pin 23, provided with a stem .23' and with a flat head or blade 232, reduced in width at its front end to form a shoulder 233, and surrounding the stem of this pin is a coiled spring 24, the tendency of which is to force the pin outward either to causethe shoulder 233 to bear against the side of the gear-wheel 2O or the wider portion of the blade to enter the locking-seat 20 in said gear-wheel, and thereby lock it against movement.

While the pinion is shown notched at 20' to constitute a locking-seat, any other form of locking-seat may be substituted, and the pin 23 may be of a different shape without departing from the invention.

Designated by the numeral 25 is a bolt havinga slotted or yoke-shaped portion 25',which is fitted over the eccentric 124 of the lockbarrel 12, and this bolt reciprocates in the space between the cover 16 and the side of the enlarged parto of the lever, a 'rabbet 65 being formed in said part to receive one edge of the bolt, as shown in Fig. 4.

As will be obvious, when the key is inserted in the slot 12 of barrel 12 it will thrust outward the pins 17' against the spring-actuated pins 17, thereby pushingthem from the recesses 122 of the barrel, and by then turning the key the barrel will be rotated, thereby causing its eccentric portion 124 to withdraw the bolt from contact with the lug 82 of sleeve 8, thus unlocking said sleeve and permitting it to be depressed against the act-ion of spring 9 to withdraw the pin or lug 8 from the notch lO in bar 10 to release the reversing-lever 8. When the barrel 12 is turned by the key, as just described, the geared surface 123 of said barrel being in engagement with pinion 20, which passes through a slot 154 in casing l5, rotates around said pinion, which is then held stationary by the enlarged part of pin 23, the latter being then located in the notch 20' of saidl pinion, the spring 2l of which isv under tension; but should it be desired at any time quickly to shoot the bolt 25 to lock the reversing-lever Without recourse to the key the operator simply'presses in the pin 23 until its blade is withdrawn from notch 20', and the pinion 2O will thenbe immediately rotated by the torsion-spring and will actuate .the barrel 12 and cause its eccentric 124m throw the bolt into contact with the lug 82 of sleeve or handle 8, thereby locking said handle against downward movement. It will be observed that the pin 23 and notch 20 constitute a detent by which the spring 2l is restrained. When the key is inserted to unlock the reversinglever 5, the pinion 20 will of course be rotated loosely around the reduced part 19' of the bolt until the notch 20 of said pinion comes opposite the shoulder 233 of the locking part of pin 23, thereby winding up the yspring 21, and as soon as this result takes place the pin 23 will be shot forward by spring 24C and will again lock said pinion against rotation.

Inassembling the parts the pinion 2O is mounted on bolt 19 and is connected with the torsion-spring 21, and the bolt is then threaded into the wall of part G, thus locating the pinion in recess 63. The pin 23 is then placed -with its reduced portion 232 iu slot 22. (See Fig. 3.) The bolt 25 is then placed in the space between cover 16 and the end of casing 15, and the barrel 12 is inserted in the `casing with its eccentric 124 in the yoke 25 of the bolt and its journal 125 in an opening of the cover 16. The pins 17 and springs 18 tare then placed in the perforations 152 of eX- tension 15 of the casing, and the casing and :its connected parts are placed in position in the body part 6, (the casing and its extension `being received in the perforation 6 and reicess 62.) The vcover 16 is then secured to =said body part by screws or otherwise.

As will be observed, the perforations pass entirely through the extension 15 of casing .15, and the-pins 17 and springs 18 can thereifore be readily inserted in said perforations, ithe bottom wall of 4recess 62 serving to pre- ?,Vent the displacement of said pins and springs when the casing is placed imposition in the body part 6, as shown in Fig. 5.

ln the modification illustrated in Figsplet and 15 the construction is the same as that `just described, with the exception that a key 13 is employed having a notch 132, and cooperating with this key is a barrel-casing 30, having a circular inturned flange 30. In Fig. 14 the blade of the key is shown in section in the slot 12 of barrel 12, and when the parts are in this position the reversinglever is locked and the key can be withdrawn; but when the key is turned to rotate the barrel 12 the edge of the fiange 30 of casing 30 enters the notch 132in the blade of the key and prevents the Withdrawal of said key as long as the reversing-lever is unlocked. By this construction thekey is retained in the lock in plain view of the operator until the reversing-lever is shifted to stop the machine or, in other words, is brought to the vertical posi- IOO IIO

may be modified or others for accomplishing like purposes substituted Without departure from the invention.
