NITED STATES PATENT OFFICE.

STEPHEN s. BARTLETT, OF PROVIDENCE, RHoDEisLAND, ASSIGNOR To HIMSELF AND THOMAS DODGE.

. l MPROVEM ENT IN HA RVESTERS.

Specification forming part of Letters Patent N 0. 40,585, dated November 10, 1863.

Be it known that I, STEPHEN S. BARTLETT,

' of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Mowing Machines; and I do hereby declare thatthe .following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which, v

Figure 1 represents in'black lines a perspective view of my improved mower; and Fig. 2 represents a longitudinal section of the same, the parts being shown in two different positions, one in black lines and the other in red lines.

In the drawings, A represents the main frame, supported by two independent drivingwheels B B, the latter having pawls a attached to their inner sides to catch into ratchet-wheels b, fast on the main shaft 0, when the machine is drawn forward by the tongue G, fastened to front arm of a metal piece, d,,the rear of which is divided into forks e e, which clasp the main axlec, as fully-indicated in the drawings. The main frame Ais suspended to the main axle or shaft'c by means of staplesf, which pass through the rear. forked ends, 0 c, and around the eyes of said ends, which reeeive the main shaft, as fully shown in Fig. 2, thence down through the main frame. By this arrangement the ton gue-piece' dis not only held in place, but the strain in backing and drawing forward the machine is in a great measure thrown upon the staplesf, thereby relieving-the main axle of much friction and which is very important in that class of machines in which the main driving-gear is fast on a main revolving axle. For instance, in my machine, ifthe tongue were hinged to the main axle, as it is, and the tilting main frame were also hinged to the main axledirect, instead of to the metal socket-pieces of the tongue-frame, then the draft of the main frame and cutting apparatus would come directly upon the main axle, thus subjecting it to very greatfriction and wear, all of which will be obviated by my present plan or the equivalent thereof. The main wheels are loose on the axle c.

. D is the main bevel-gear, fast on the axle c. The gear D drives a small bevelgear on the front end of shaft 9, which has a cog-wheel,

it, fast thereon, and which in turn drives a small cog-wheel on the rear end of the crankshaft t', which gives motion to the pitman 7' and cutters k. Shaft g is supported in bearings fastened to the top' of the mainframe, while the crank-shaft hearings or boxes are fastened to the bottom or under side of the frame. To the front inner corner there is at taehed a curved metal arm, E, to the lower end of which is hinged the shoe F, which supports the heel of the finger-beam G, to which are fastened the slotted guards or fingers m. The other end of the finger-beam is supported by shoe H. Owing to the hinging of the fingerbeam, it can be folded up at the side of the machine, as indicated in the drawings.

I is the drivers seat, fastened to the rear of the tongue. It will be seen that the fingerbeam can rise at either or both ends, and that, too, without affecting the motions of the drivers seat or rear of the tongue.

' To the front of the frame is "hinged a linkpiece, a, which passes up through a slot in the tongue, whereby the extent to which the front of the frame can fall can be easily regulated by a pin, 0, placed in one of the holes in the link-piece n, above the ton gue.

To enable the driver to elevate the front of the frame and heel of the finger-beam when the machine is in operation, and also to elevatethe finger-beam after itis folded up at the side of the machine, so that the machine can be conveniently transported from one field to another, a lifting-piece is attached to the top of the tongue.

In the stand-piece turns ashafhq, having a foot-lever, s, and a hand-lever, t, fastened to it, the foot-lever being connected to the linkpiece a by means of an arm, o.

The driver can use his hand or his foot to raise the frame, or both.

In Fig. 2 the folded finger-beam is represented in red lines. as elevated for transportation from one field to another.

The pawls a are held down by springs a", which springs have booked ends b, whereby when the pawls are elevated to a certain height the hooks catch int-o notches c in the pawls and hold the latter out of action. This is quite a simple and yet effective mode of keeping the pawls entirely out of action.

Having described myimproved mower,what

I claim as my invention, and desire to secure the metal tonguesocket-pieces, or their-equivahy Letters Patent, is lent, and not upon the main axle, whereby The combination, in a mowing-machine, of much friction is'avoided and the machineren- :1 tilting frame, to which the finger-beam'is atdered of more easy draft, substantially as detached and a hinged tongue in such a manscribed.

ner as that the frame and tongue shall both STEPHEN S. BARTLETT. have a common axis of motion, while in draw- Witnesses: ing the frame and cutting apparatus forward DAVID V, GERALD,

the draft thereof shall come directly upon the M. D. DRAKE.
