IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 33,263, dated September 10, 1861 Reissue No. 196l. dated May 16, 1865.

.To all whom 'it may concern:

Beit known that I, WORDEN P. PENN, of

l Belleville, in the county lof St. Clair and State of Illinois, have invented a new and Improved Harvester; and I do hereby declare that the following is a full, clear, and exact description caster-wheel l'or sustaining the outer end of the finger-bar and platform, and adjusting said end.

Similar letters ol"A reference indicate corresponding parts in the several'ligures.

r The main object of myinvention is to attach the linger-beam to a carriage-fraaie which can be elevated or depressed at its rear end in such manner that the entire cutting apparatus can be adjusted and set at any desired inclination independently ofthe inclination given to said frame, and while this is the case provision is made for allowing the outer end of the cutting apparatus to rise and fall and accommodale itself to inequalitiesin the surface ofthe ground traveled over, or for securing the finger-bar rigidly to the main trame, as will be hereinafter described.

Another object of my invention is to'combine with a jointed carriage-frame, the rear portion of which is hinged or -pivoted tothe axle of a.snpporting-wheehtwo caster-wheels, one of which sustains the rear portion of said frame at whatever height it may be desired to adjust it, while the other sustains the outer end of the cutting apparatus at whatever height it may be desired tof adjust it, as will be hereinafter described.

vAnother object of my invention is to combine with a finger-beam which has a lateral rocking motion a contrivance for allowing said beam to rise and fall and accommodate itself to the inequalities of the surface passed over, and for regulatingsaid motion. l

Another object of my invention is to enable the driverrto adjust the cutting apparatus and give it the desired inclination by means ofa lever, which also enables him tov raise or depress the rear of the main frame.

Another object of my invention is to combine with a carriage-frame, which is pivoted at or near its front endto the axle of a single main supporting-wheel, and which has its cutting apparatus pivoted near its rear end, a contrivanceifbr enabling the driver to start or stop the motion of the sickle at pleasure, as will be hereinafter described.

Another objectof my invention is to provide for sustaining the outerend of a fingerbeam which hasa forward and backward rocking motion, at any desired height from the ground, upon a wheel or roller, as will be hereinafter described.

' To enable others skilled in the art to make and use my invention, I will describits construction and operation.

The main supporting-frame of my machine consists of a forward portion, A, which carries the draft-pole c, and which is pivoted at its rear end to the transverse axle-tree a of the large supporting-wheel b, and a rear portion, A', which is plvotetl at its front end to said axle-tree, and which carries the cuttingv apparatus and contrivances foroprrating the saine.

nal bolt, n, t0 a strap, n, that is rigidly secured tothe outer end of the rocking beam, as shown in Figs. 1 and 2. The inner end ot' the {ingerbeam q extends about halt-way across the frame A', and hasl an upright post, w', connected to it, which passes up' loosely through a hole which is made through the rocking beam k. By means of a pin which is passed through the post w', above the beam It, the finger-beam can be secured rigidly to this beam k, so that its outer end will not rise or fall; or, if desirable, the said pin can be removed, so as to allow the finger-beam te vibrate freely about its pivot-bolt n?. It will be seen that the finger-beam q is connected to the frame A' by two joints, one of which allows it to rock backward and forward, so that the points of the tin gers q' can be elevated or depressed and inclined at different angles, and' the other joint allows the finger-beam, at its outer end, to rise and fall andA accommodate itself to inequalities in the surface of the ground. The fingers q' may be of any of the well-known forms, and they maybe secured in any desirable manner to the linger-beam q; but the form which I have represented in Figs. 3, 4, and 5 has been found to answer the best purpose, and will be hereinafter described.

h is the sickle; s, the divider, and i the platform, which latter is connected to the fingerbeam and to an outer divider-beam, s, and the whole are strengthened by means of a diagonal brace, which is indicated in dotted'lines, Fig. 2.

A lever, m, is connected by a standard, l, to the rocking beam k, and projects forward of the drivers seat d, as shown in Figs. l and 2. This lever m has its fulcrum upon a collar which is formed near the upper end of a caster-wheel standard, n', a longitudinal slot being made through said lever to receive this standard, as shown in Fig. 2, and to allow the lever to receive a slight.longitudinal movement. The forward end of lever m is provided with a number of holes, which receive a pin that connects this end of the lever to a vertical post, 1), which is also provided with a number of holes to allow the lever to be se-` cured to it at different points. The casterwheel o has its vertical standard u' connected to the frame A' in such manner that this frame can rise and fall and still be sustained upon the caster-wheel. By depressing the forward end of the lever m the driver can elevate the rear end of the frame A', and with it the cutting apparatus; or by elevating the front end of the lever m the driver candepress the rear end ot' the frame A' and cutting apparatus. It will be seen that as the frame A' moves about a center (the axle-tree a.) the inclination ofthe cutting apparatus would conform to that given to this frame in adjusting its rear end up and down. This is compensated for by means of the rocking beam k, and the provision which is made for giving the lever 'm a.

longitudinal movement. Thus when the cutting apparatus is elevated by elevating the frame A' the driver can raise the points ofthe fingers by pushing'the lever m backward. By drawing this lever forward the front portion ot' the cutting apparatus will be depressed. The desired inclination of the cutting apparatus may be secured without regard, to the inclination of the supportingframe A', and by means of the lever mi, which is employed for elevating said frame.

The caster-wheel 0 serves as a rear bearing for the frame A', as well as the fulcrum ofthe lever m, and the caster-wheel tserves as a support forthe outer end of the cuttingapparatus. The spindles of both caster-wheels are adjustable-.. e., both caster-wheels sustain the rear portion of the machine at whatever height it may be desired to adjust this portion. The standard t' of the caster-wheel passes up loosely through the divider-beam sand receives pins and washers y y on each side of said beam, which secure the standard in place. By removing said pins the outer end of the cutting apparatus may be set to run at any desired height from the ground. In my machine the outer caster-wheel also serves to relieve much of the strain on the joints which allow the beam K and finger-beam q to rock.

, The large spur-wheel B, which is keyed to the axle-tree a, engages with the teeth of a pinion-wheel, B', and this pinion gives motion to the bevel spur-wheels C D when theelutch jis moved into gear with the wheel G; but when this clutch is not engaged with the wheel C no motion is communicated to the bevelwheel D. This latter wheel is keyed on the front end of a longitudinal crank-shaft, E, to the crank of which the pitman-rod c 1s connected, which gives a reciprocating motion to the sickles h. A lever, w,which lasits fulcrum at J, is used by the driver for moving pinionwheel B', 'having the clutch j, and starting 0r stopping the motion of the sickle-bar.

The tinger-beam kis made narrower at its front edge than it is at its back edge, as represented in Figs. 1 and 4, andv the fingers q' may be secured to this beam by an upper extension projecting over the finger-bar and receiving bolts through it, as represented in Figs. 3, 4 and 5; or this upper extension may be omitted and a lower extension projecting under the finger-bar used in its stead. In connection with these modes of securing the iingers to their bar or beam I employ lateral flanges az, which abut against the edge of the finger-beam and receive screws through them for securing the fingers to this beam.

The flanges z also constitute a back guide for the sickle-bar, as shown in Fig. 4.

In my invention I do not confine myself to the exact construction of frame A and A', as

a differently-constructed .frame can be ,used and the same results be attained; nor do I contine my invention to a single main-wheel machine, as it may be applied to a' two main wheel machine by a little variation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv,

1. The combination of the jointed frame, by which the sickle may be elevated, with the means for counteracting the angularity that would otherwise effect the operation of the sickle, and with a linger-bar which may be either flexible or rigid, the whole constructed and arranged in the manner described.

2. Connecting the finger-bar to the frame by means of the hinge-joint and the upright, in the manner'described, so that the connection with the said frame may be made either ilexible or rigid, as'specied.

3. The arrangement of the transverse rocking beam Icon the undersideof frame A',in combination with the fnger-bar'g, substantially in the manner and for the purpose described.

4. Arranging the transverse rocking beam k on the under side of the frame A' and pivoting the linger beam q to it thus arranged, substantially in the manner and for the purpose herein described.

5. Applying the lever m to the machine in such manner that it will serve the double purpose of elevating the cutting apparatus and also of tilting it forward or backward, substantially as described.

6. The arrangement of the two caster-Wheels o t, frame A A', jointed upon the axle-lever m, serving the double purpose described, and nger-beam q and rocking beam k, in the manner and for the purpose herein described.

7. Arranging the spur-wheel B, sliding pinion-wheel B', clutch j, lever w, bevel clutchwheel C, crank-pinion D, with the frame A A', rocking beam 7c, and jointed linger-beam q, all in the manner and for the purpose described.
