UNITED STATES' PATENT @artica SILAS C. MATTESON, OF OSCEOLA, IVISGONSIN.

IMPROVED MECHANICAL MOVEMENT.v

Specification forming part of Letters Patent No. 50,943, dated Xovember 14, 1865.

To all whom t may concern:

Be it known that I, SILAs C. MATTESON, of Osceola, in the county of Fond du Lac and State of Visconsin, have invented a new and useful Mechanical Movement 5 and I do hereby declare the following to be a full, clear, and exact description of the nature, construction and operation ot' the saine, reference being had to the accompanying drawings, which are made partot this specification, and in which- Figure l is a side elevation ot' an apparatus illustrating` my invention. Fig. 2 is a sec tional top view ot' the double rack and lever, hereinafter referred to; and Fig. 3 is asec tional side view ofthe same.

Similar letters ot reference indicate correspending parts in the several gures.

This invention consists chietiy in the combination of a double rack-bar with a lever oi' peculiar construction for elevating, dragging, or moving weights or heavy bodies.

The following description will enable others skilled in the art to which my invention appertains to fully understand and use thesamc.

A represents a double rack-bar, ot' any suitable material, and having its teeth disposed so that the points ot' those on eitherside shall be longitudinally midway between the points ot' those on the opposite side.

B is a lever, formed with a beveled opening, B', whose upper edges or points, b Z1, alternatelyconstitute the points ot'action of said lever in moving the rack-bar A. The sides of the opening B have such bevel or divergence and the points b b are at such distance asunder that if the rack-bar or lever be vibrated so as to cause the beveled sides of the opening B'to approach or recede from the rack-bar, then either the rack-bar or lever may be made to move either way in the direction of the lenth of said rack-bar, which result is produced by the points l) b engaging with the teeth of the rack-bar as the vibration continues. By the use of these two devices great power may be applied to any object to which itis desired to impart motion.

A few practical illustrations of the mode of operating the device under varying circumstances may serve to clearly define the extent of its utility.

If the machine is to be used for elevating weighty bodies, the lever B is mounted within a frame, C, and adapted to be vibrated upon the fulcra 1) D. ,The rack-bar A, which occupies the opening` B', has the object attached to its lower end by any convenient means-say the ring and hook represented in Fig. l. By now vibrating the lever B so as to make the sustaining-point b, which is engaged with the teeth ot' the rack-bar, raise the latter, the pointb on the opposite side of the lever descends while the nearest tooth ascends until it reaches a heighta little above the point I) last mentioned, when a reverse vibration ot' the lever B throws this point under the tooth which is now next aboveit, and the tooth and acting point at the opposite side are thus relieved ot' the weight while the elevation ofthe rack-barcontinues as before. lt` desired the object may be raised as high as desired by the continued vibration ot' thelever B, but as soon as the weight depends upon the rack-bar, the upward motion ofthe latter, together with that ot' the weight, may be effected by tixing the lever in an immovable position and vibrating the ruck-bar itself, and hence giving a swinging motion to the weight or object which is attached to itsend. It will be seen that by this mode the weight7 by its momentum, is made serviceable in its own elevation.

In view ofthe above description the lowering office of the amiaratusneeds no special description.

My apparatus may be used as a horizontal machine-that is to say, it may be laid dat and the power applied by vibrating the lever or rack-b-.irin a horizontal instead ot' a vertical plane, as in the elevating process. In this position the apparatus can be used for pushing or pulling, and the weight may,ifdesired, be attached to and moved with the lever B, in which case the rack-bar A is fixed. When the rack-bar is moved upward by the vibration ot the lever it is desirable, if not absolutely necessary, to prevent the rack-bar from swaying or moving laterally. To meet this object I empfoy the pivoted guides E E, which are turned down in order to steady the rack-bar, but which may be turned aside out of contact therewith to admit ot' the oscillation of the same. Guides of any form may be employed for this purpose.

This apparatus can be improved possibly by arming the teeth ot1 the rack-bar and the points of action ofthe levers with frictionrollers. I further propose to provide the points of action with metallic plates, as shown in Fig. 3, which are held in place by set-screws and adjusted as they become worn by the action of the teeth.

The apparatus may be employed in all cases where power is to be applied to movable objects, such as raising and lowering hay, stone, bales, barrels, mounting cannoli, removing houses, and extracting stumps.

By graduating the lever B,as shown in Fig. 1, and applying a weight thereto, it may be used for ascertainin g the weight of an object in course of elevation.

The staples F F are for the attachment of ropes, by which the leverB maybe suspended by ropes, which may at times be expedient.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with the double rackbar A, of the lever B, formed with the beveled opening B', adapted for the purpose explained.

2. The adjustable guides E E, for steadying the rack-bar during its movement, substantially as described.

3. Graduating;` the lever B, for the purposes herein specified.

To the above specication of my new and useful mechanical movement havesignedmy hand this 29th day of June, 1865.

SILAS C. MATTESON.
