BENJAMIN P. LAMASON AND SIDNEILT D. KING, OF ALEXANDRIA, VIRGINIA eMPaovEMENT In sieNAL-'rowsae Specification forming part of Letters Patent No. 47,026., dated March 28, 1865.l
.To a/ZZ whom it may concern.-
Bc it known thatwe, BENJ. P. LAMAsoN.
.scription of the construction and operation of the same, reference being had to the annexed drawings, and to the letters of reference marked thereon, making a part of this specication.
To enable others skilled in the artv to make,
and use our improvement, we will proceed, to describe its construction and operation. We construct it substantially of wood and grou,
xas shown in the accompanying drawings, in
which- PlateNo. I. Figure I is a plan view showing the position of the screws, wheels, &c.-
A is a wooden frame, resting upon and secured to sills B B of truck-trarne C C U C,
vertica-l'iron screws; I) D D D, cog-wheels;
E, pinion-wheel; F, vertical shaft. This also -shows the form and position of' truss-bolster.
elevation through a a', showing the manner` of securing' the screws, Ste., to frame A and sills B. G G C C are vertical screws; D D, spur-wheels; F, vertical shaft, upon the top end of which is secured the pinion-wheel E; H H, beveled gear-wheels, secured to lower end of vertical shaft' F and crankshaft 0; Gr, crank; I, bolster; K, iron truss on bolster; U2 2, pivots on ends of bolster; L L L, iron burrs; d d', `journals on lower ends of screws; c c,journalboxes secured to sills B, in which the screws C revolve.
APlate No. 2: Fig. l is a longitudinal side elevation showing' the entire combination. M M M M are wooden arms or levers, which compose the tower; N N, short arms, the top ends of which are secured to the lower ends of tower-levers M, midway between the points b b. The lower ends are secured to the frame A at the pointf. The object ot these arms is to secure the tower to the frame. The arms are so adjusted as to allow the rollers P P on the ends of tower-levers to have a continuous bearing upon the frame A, upon which are secured proper guides to keep the rollers in position. l represents truss-bolster. The pivoted ends C2 C2 pass through the second series of.. tower-levers at J. L L are iron burrs, which are secured to under side of bol# ster, and inpwhich the screws U C O C revolve.
lhesecond series of levers being secured to the bolster I, and the first or lower series being secured to frame A by means of the short arms N N, as shown, the following is the mode ot' operation: APower being applied to the crank G, motion is transmitted, through the medium of the'beveled gear-wheels H H, vertical shaft F, and pinion-wheel E, to spur-wheels D D l) D, in which vertical screws U U U C are secured, and cnusin g them to rotate either backward or-forward, as may be desired. Thus, motion bei-ng given to the screws which operate in 'the burrs L L, the bolster I is carried upward or downward at will. This movement of the bolster gradually opens and extends the towerlevers M until they assume the desired elevation. l t
Towersare easily elevated by this improved mode, and by these means compose a strong and substantial structure. The saine device, with slight deviations, can be applied at the top or last series of the tower-levers as well as at the first series.
What we claim as our invention, and desir to secure by Letters Iateut, is-
1. The short arms N N and the bolster I, when constructed and usedin the mannernnd for the purpose herein described.
2. lu combination with the above and with the vertical iron screws G C C C, the spurwheels D D l) D, pinion-wheel E, vertical shaftv F, and bevel gear-wheels II H, arranged and operating substantially as and for the purpose herein specified.
