3.PECIFICATION forming part of Letters Patent No. 456,471, dated July 21, 1891.
Application filed January 17, 1891.
T0 aZZ whom, it may concern.-
Be it known that we, JOHN BRAUN and HENRY DECK, citizens of the United States, both residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Lawn- Mowers, which improvement is fully setforth in the following specification and accompanying drawings.
Our invention relates to improvements in lawn-mowers; and it consists of mechanism substantially as hereinafter described for either connecting or disconnecting the operating train of gearing of the knife-cylinder and the running wheels of the device.
It further consists of the combination of parts hereinafter set forth.
Figure 1 represents a perspective view of a lawn-mower embodying my invention. Fig. 2 represents a longitudinal section of the parts of the mechanism embraced in my invention. Fig. 3 represents a modification of the same. Fig. 4: represents a perspective view of detail parts of the device. Fig. 5 represents a perspective view of the outer face of the gearbox, showing the lock. Fig. 6 represents a perspective view of a detail part. Fig. 7 represents a sectional view on line .1: ac, Fig. 2. Fig. 8 represents a partial side and partial sectional view of the pawl-holder with pawl.
Similar letters of reference indicate corresponding parts in the several figures.
Referringto the drawings, A designates a lawn-mower having the running wheels B, with the axle C, the knife-cylinder D, and the roller E, all of usual and well-known construe tion, the said knife-cylinder being operated by means of a train of gearing located in the gear-box G, which latter is secured to the axle (J. Journaled in the said box G is a gear-wheel II, having a hub or sleeve portion J, which is slotted at K on opposite sides thereof. The body of the said wheel is also provided with a circular collar or flange L, surrounding the sleeve J and forming a recess M. Mounted on the sleeve or hub J is a gearwheel N, having a sleeve portion P, adapted to contact with the collar L, and having its inner wall provided with the ratchet-teeth Q, adapted to engage the ends of st--.pawl R,
Serial No. 378,105. (No model.)
which loosely rests in the slotted end of a holder S and the slots K of the sleeve J. The said holder S consists of a slotted stem or pin adapted to be inserted through the side of the box G and into the journal or hub J of the wheel ll, and is provided with a head T, by means of which the said holder may be readily operated. The slots K are of greater length than the width of the pawl R, so as to permit the longitudinal movement of the holder S.
Pivoted to the outer side of the box G is a lock U, having a recess in its under face coinciding with the periphery of the holder, so that. when the latter is operated so that the pawl is removed from contact with the ratchetteeth, as in the position shown in Fig. 2, the lock, when its free end engages the stud V, will prevent the said holder from being moved inward.
WV designates guides for the holder, the same being connected with the outer face of the box G, and having their inner faces conforming to the shape of the head T of the said holder. It will be noticed that when the holder is inserted in the box G and sleeve J so that the ends of the pawl R are in contact with the ratchet-teeth Q, the rotation of the gear-wheel N which, as is usual in devices of this character, is in contact with a gear-wheel connected with a running wheel B, will rotate the sleeve J along with the wheel II, and thereby the usual wheel on the knife-cylinder of the mower, so as to rotate the latter. The slot in the holder in which the pawl R is inserted is of such shape as to permit a rocking motion of the pawl therein and thereby permit the backward movement of the said wheel N without rotating the sleeve J and gear-wheel ll, so that in the backward movement of the running wheels the knifecylinder is not rotated.
hen it is desired to stop the movement of the knife-cylinder during the forward movement of the running wheels, the holders S are drawn out and looked, as shown in Fig. The ends of the pawl R being no longer in contact with the ratchet-teeth Q, the rotation of the latter does not aifect the sleeve or hub J nor the wheel II.
In Fig. 3 a modification is shown wherein the main gear-wheel H of the operating-train is secured to the gear-wheel C, that connects with the running-wheel gear by means of a 5 disk D, having the pins E, which enter openings in said gear-wheels H and O,the holder or shaft F having an inner bearing on the casing of the gear-box.
Having thus described our invention,what
[O we claim as new, and desire to secure by Letters Patent, is
l. A lawn-mower having an axle with a gear-box thereon, a gear-wheel journaled in said box having a slotted hub with a surr 5 rounding recess, a gear-wheel on said hub and having a sleeve adapted to contact with said hub and with ratchet-teeth thereon, a slotted holder adapted to be inserted through the said gearbox, and a pawl in said slotted 2o holder and engaged by said ratchet-teeth, said parts being combined substantially as described.
2. A lawn-mower having a gear-boxon the axle thereof, a gear-wheel journaled therein having a slotted-hub, and a surrounding circular collar forming a recess, a gear-wheel mounted on the said hub and provided with a slotted sleeve and ratchet-teeth, a holder with slotted end, a pawl resting loosely in 0 said slotted end and slotted sleeve, and a lock for said holder, said parts being combined substantially as described.
3. In a lawn-mower, the combination of a gear-box attached to an axle, a gear-wheel journaled in said gear-box having a slotted hub or sleeve connected therewith, a circular collar on the body of said wheel surrounding the said sleeve and forming a recess, a gearwheel mounted on the hub having a sleeve adapted to contact with the said collar and with ratchet-teeth on its inner wall, a slotted holder adapted to be inserted through the side of the said gear-box, and a pawl resting loosely in said slotted holder and adapted to be engaged by the said ratchet-teeth, substantially as described.
4. A support, a gear-wheel j ournaled therein and having a slotted sleeve on one side, a gear-wheel journaled on said sleeve and provided with ratchet-teeth, a holder with slotted stem movable in said first-mentioned gearwheel and sleeve, and a pawl in said holder having its ends adapted to be engaged by the ratchet-teeth, said parts being combined substantially as described.
5. A support, a gear-wheeljournaled therein and having a slotted sleeve, a second gearwheel mounted on said sleeve and having ratchet-teeth, a holder with slotted stem,and a pawl in said slots having its ends adapted to be engaged by said ratchet-teeth, said holder being movable endwise in its bearings, said parts being combined substantially as described.
