TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALFRED B. BEAUMONr, of Austerlitz, in the county of Kent, and State of Michigan, have invented certain new and useful Improvements in Steam-Machinesfor Extracting Stamps; and I do herebydeclare that the followingis a full and exact description ofthe same, refcrencebeing had to the accomy panying drawings, making part of this specification, in which- Figure 1 is an elevation of my iniproved machine,

Figure 2, a plan.

Figures 3 and 4, detail`views. p

Like letters of reference indicate corresponding parts in all the figures. v

My invention consists in combining a steam-enginewith a machine for drawing stumps, in the manner hereafter described, and in the arrangement ofgparts consequent to, such conibination.

In the drawings- Y d A A represent' a triangular wooden frame or derriclc, with central uprights, U U.

Thetops are surmounted by iron caps, V V, having descending lugs, against which come the-ends of the side-timbers or braces. v

W W are iron loops or stirrups, depending from the'caps, and sustaining the ends of' the timbers.

XX are side-timbers ofthe frame, sustaining the bearings ofthe roller-shaft, and the ends setting'iri loops W W. v

The whole frame is suitably strengthened and supported by iron rods and wooden braces, and arranged Y I with wheels B B, for transporting the same, s aid wheels revolving on false axlesor gudgeons rigidly attached tosustaining-ba1"s, C C, pivoted at yy to the side of the frame, which bars raise or lower the machineby means ot large `pulleys, aa, and smallwgrooved wheels, ZJ b, and having cords or chains, c e, attached to the ends of the sustaining-bars C C, and passing around the pulleys 'and grooved wheels down to side-piece of' wooden frame, wherethe cords either extend through or are connected to an iron rod running in cleats having hooks at the ends, and operated by attaching horse or other power thereto.

By means of this arrangement the machine can be elevated at pleasure, by drawing at either end of the cords, and changed to any-position, accordingto which endthe moving power is applied. l

' z z are'spring-catches,which connect with the teeth or pinstoff pulleys a a, and hold the machine in 'position when raised on the wheels, and prevent it from descending.

The two catches, on' opposite sides, are suitably attached, and'work simultaneously.

'D is a boiler attached to the frame, with furnace, g', and/smokestack, l. A water-heater may also be used, it' desired. A d' l E is the cylinder, and d the water-supply pipe running from a large reservoir, Z, which is attached to the derrick opposite the boiler, to counterbalance the weight.V

m is the `rod which operates the cocks or plug-valvcsin t'hesteam-che'st; 'n n, projections on this rod, with which clavicular projections, o, from the cross-head, come in contact to operate the valves. l v

Gris the guide for cross-head I-I, which latter is made of such length that the line of resistance from the connectingQrods I I, being continued downward', would strike about the centreoi the piston.

' By this arrangement there is scarcely anyfriction on the guides.

These connecting-rods I I are pivoted at lower-ends to the cross-head, and at the upper ends to arms, J J, turning on centre or shaft M, said arms being provided with pawls, It It, one pointing up and the other down, and operating alternately on the ratchet-wheel z'. l y y 'Y I The pawls are held in contact with the ratchet-wheel by springsyy, attached to arms JJ, and have lateral projecting pins or studs, q g.

As the arms are raised, lthe' pawl on one'side engages with a tooth on that side of the `wheel, and carries around; while the pawl onthe other side rides over the teeth, and on the desccntof the arms thispawl catches,

and .the other one slips in turn, thus alternating in action, but producing a forward turning movement of the ratchet-wheel, both in the up and down action.

In order to throw these pairls out of gear, when a stump is to he lowered after having been extracted, n cam-plate, y, is provided with cams,jj, which, when turned to the proper position, strike the pins q q, thus elevating theyrn. l

The cam-plate is operated by jointed rods, K K, connecting wit-*h hand-lever L.

The ratchet z' works one end of shaft M. The other end isprovided with a pinion, p, giving motion to a train of gears that actuate roller N. I arrange on and attach to this roller a number of iron or steel-wire ropes, s s s, with loops darned on the ends, and then put into recesses, t t t, in roller N; then a rod is passed through the roller and through cach'of these loops. The other ends of these wire ropes arermly secured tot an iron yoke, 11 which is provided with suitable chains and hooks for attaching lto and extracting stumps.

I is a brake-head, operated upon by the brake Q, with connecting-cord or rod, R, which passes down over suitable pulleys to and is actuated by lever S, attached to frame A, and having suitable holding-attachments.

The operation of the machine is so simple as to hardly need explanation. With the derriek elevated over the driving-wheels, and horses or oxen attached, it is drawn over the stump to be extracted, andthe roller operated to let down the wire ropes and tackle, which are then connected to' suitable fastenings about the stump, thcn'steam applied, and the stump drawn out.

By uniting a steam-engine to a derrick, much oi' the labor of moving two machines and arranging the connections is saved, and I am not awarethat the two have ever been combined in one machine before.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination and'arrangement, with the derrick A A, mounted 'upon wheels B 130fl the steam-' engine D E g, with stack Zand the reservoirZ, the whole being` in portable form, whereby the machine may be moved over a stump, and the steam applied for extracting it, as herein set forth.

2. The combination and arrangement of the connecting-rods I I,jointed arms J J, pawls h 7L, with the ratchet-wheel z', whereby the forward turning ofthe ratchet is produced at both strokes, in the manner and for the purpose specified.

3. The combination, with the pawls 1th, of the cam-plate y, having 4cams jj, rods K K, and lever L, for throwing said pawls out of gear, as herein set forth. f

4. The arrangement-of the wire ropes s s passing through slots t t, 4and retained by a rod passing through I the loops, as set forth.

5. The arrangement of the brake Q, connecting-cord or rod R, and lever' S, with the brake-wheel P, as herein described. y

6. The combination and arrangement, with the wheels B B, of the swing or sustaining-bars C C and the rope or chains c c, pulleys a b, and holding-devices z z, as herein set forth.

T. The arrangement, as a whole, consisting of the derricl: A, steam-engine D Eg, connecting-rods I I, arms J J with pawls h, ratchet-wheel z', roller N with wire cords orchains s s s, and adjusting-wheels B B, all as herein set forth. y

.In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

ALFRED B. BEAUMONT.
