G'. KILBURN. I MACHINERY FOR RAISING HEAVY onms. V No. 894. mmmzn AUGUST 25, 1835.
UNITED STATES PATENT OFFICE.
GEO. KILBURN, OF WALPOLE, NEW HAMPSHIRE.
MACHINERY FOR RAISING HEAVY BODIES.
Specification of Letters Patent No. 894:, dated August 25, 1838.
of, the application of said principles by i which the same may be distinguished from other inventions, the manner of using the same, together with such parts, improvements, or combinations, I claim to be my. invention and hold to be original and new, I have hereinafter setforth and described. which description, taken in connection with the accompanying drawings, herein referred to, composes my specification.
Figures 1, 2, 3, Plates 1 and 2, represent my improved machinery, Fig. 1 being an elevation of one side; Fig. 2 a detailedview of some of the parts on the opposite side and Fig. 3, an end view. I
A A A, represents in Figs. 1 and 3 a strong'frame of wood, iron, or other suitable material, shaped as seen in the drawings, or otherwise properly formed. To th1s frame, is connected a second frame or two standards B, B, of wood, iron, or other metal, answering the intended purpose, the
said standards being connected together at their upper parts, by a cross bar 0, C, 1, 2, 3.
A horizontal shaft D, is supported in suitable bearings or boxes, attached to the standards B, B,,Fig. 3. Onthis shaft are two metallic pulleys or cams a, b, to the circumferences of which chain belts c, d, are attached at an extremity of each, as represented the drawings. The opposite links of the chain belts connect with arms, or pitmen E, F, whose other extremities are attached to, and swivel on the center pins 6, b, of a system of progressive levers, or toggle or shelf joints G, H, I, K. The lower ends of the toggles I K rest, and move in step pins 0, c, or other suitable bearings. The upper ends of the toggles G II, also rest and move in a similar manner on step pins on bearings, near the extremities of a beam or bar L, of wood or metal. g
M, N, isa square or other proper shaped metallic bar in the central part of the machinery, the same passing and moving freely through slots in the:beam L, cross bar or shelf 0, 0, and top beam of the frame work A, A. To the lower extremity of the bar M N, an eye 0, is attached by a bolt 6 f. To
this eye, the body to be raised, may be con j formed on two 1 Figs. 1, 2, 3.
nected in any convenient manner. The bar M N, has teeth 9, g, h, h, of a proper shape,
z, z, is, is, are sets of pawls vibratingfin jstep pins, or proper joints, attheir lower j extremities, and pressed inward toward the 1 bar M N, by springs Z, Z,m, m, placed and acting on them, as seen in the drawings, or
instead of these springs the objectof press- 7 1 ing these pawl toward the bar M N, maybe attained by any other suitable system of springs applied to the same, 1 i
P, Figs. 1, 2, is a pendulum handle or rod,
attached to the end of the shaft raisopposite sides, as seen .in
ing the handle P, and of course turning the shaft D, attached thereto, the toggle joints G I, H K, are drawn into straight. lines with each other, and thus lift, or push upward,
the beam L. When the handleP, is lowered, the springs '11., 0, press "outward the 'toggle joints, and thus cause them to come into angular directions with each other, and, lower the beam L, again to its original posi{ tion. By this, alternate action of the toggle joints, the bar M, N, and any heavy body attached to the eye 0, are raised or lowered lat pleasure. This operation is effected by the action of the pawls i, z, 7c, kfand may be described as follows.
The ends of the pawls in contact with the A bar M N, are notched, or have teeth formed on them to correspond with, and enter-into, the interstices between the teeth h, it, g, 9.
As these pawls are always kept in contact, or pressed'against the bar M N, when the jtoggles lift or push upward the beam L, by
the springs Z, Z, m, m, the bar M N, isthus Fraised withthe beam L, by the'action of the toggle joints. During the above operations the ends of the pawls is, 70, slide over the teethg, g, and retain the bar M, N, atthe height gained. As the toggles are pressed goutward by the springs 11, 0,:during the downward movement of the handle P, the .ends of the pawls 11, z, intheir turn,slide jover the teeth h, h, during the downwardmotion of the beam L, and thus when the beam L, is next raised by the toggles, act
again on the bar M N, as before. The operation of lowering the bar M N, is thus efiected.
R is a clamping screw, which confines a rod 9, q, in the position denoted in the drawing. The rod p, g, has a spring 8, wound around it, the same being confined at its upper extremity, by a pin or shoulder 1",
' and resting at its lower end on the top of the shelf 0, 0, Fig. 1. On the top of the rod p q, is a cross piece If at, having two pins '0, w, see Fig. 2, projecting at right angles therefrom, andextending under the pawls 2', 2'. By loosening the clamp screw It, the rod 9, rises so that the pins '0, w, are pressed or raised up by the springs, against the pawls '5, z; the said pawls being held in 7 :13, pins 6, e, Fig. 1, and clamp screw d,
are attached to the rod 00 similar to those before described, as connected to the rod 0 g. The object of the clamp screws R, and
their lowest positions, while the'operation of raising th'e'bar M N, is going on; or in otherwords, to throw off the action of the projections 21, w, e, e, from the pawls.
f f, g g are guides for steadying the motion of the rods 79 g, m y. By lowering the clamp screws d, R, the springs press the projections e, e, o, w, against the under Side of the pawls i,'i, 7c, 70. When the toggles are brought in a straight line with each other, the upper pawls a, z, engage with the bar M N, the lower pawls at the same time being pressed away from the teeth 9 g,
,the bar M N, just before the pawls i, 2', by 55' bearing on the projections o, w, spring outward from the teeth h, h. Then as the toggles are brought to their upright positions again, the upper pawls i, i, slide over the projections 41,10, and enter the next succeeding notches or teeth, just before the 1 lower pawls 7a, 70, by the action ofthe spring 00, are thrown out from the teeth 9, 9. Furthermore, as the toggles recede, the bar M N, is lowered again, a little, and so on until the operation is completed. If the same should be desired, another series of toggle joints with rising head bar and pawls, may be placed on the two other opposite sides of the machine, these to raise the bar 'MN, when the pendulum handle descends,
so that at each vibration of the handle, the 7 bar M N, may be raisedor lowered. Or, if it should be preferred, to place the second seriesof toggle joints outside of the first, or on thesame opposite sides of the frame A, A, the same can easily be accomplished.
Instead of a bar M N, as above represented and described with teeth, a chain properly constructed may be substituted therefor, and in many instances this will be found preferable. Instead of the pendulum handle attached't o the shaft D, a crank or other proper machinery may be applied to give the shaft a rotary motion. And in order to cause it to operate on the toggle joints it may have bell cranks, cams or other suitable apparatus, which, by steam or other proper power applied to the shaft shall caus the toggles to advance and recede' as before mentioned. The machine may also be applied to pressing substancesa piston or follower being fixed to the end of the bar M, N, working in'a cylinder or box con taining the substance to be pressed. d, is to confine the-cross bars 6 u, a b, in
Having hereinabove explained my improvements I shall claim 7 in the same as follows: I r
1. Thecombination and arrangements of machinery substantially as set forth and described to operate together and'for the purposes before mentioned, that is to say, the application of the toggle joints pawls and other machinery to the bar M N, to'operate on the same as I have particularly described. 3 2. I also claim the application of the machinery that is connected to the pawls for producing the downward motionofthe bar F which as before described was repre-..
sented as similar to that above explained and seen in Figs. 1, 2, 3. The application of pawls on opposite sides of a toothed'rack or bar, to operate on said bar so as to raise or lower the same by the aid or action of toggle joints in the various ways I have heretofore described, for raising weights or pressing substances.
In testimony that the above is a true description ofmy said invention and improvements, I have hereto set my hand this twelfth day of July, in the year eighteen hundred and thirty eight.
