WATER-TOWER ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 463,749, dated November 24, 1891.

Application filed August 6, 1891. Serial No. 401,870. (No model.)

To all whom it may concern:

Be it known that I, THOMAS RAwsoN, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Water-Tower Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. The object of this invention is to provide a water-tower on an aerial truck with a hose and nozzle which can be directed and operated from the foot of the tower, simple and cheap in construction, easily adjusted, and not liable to get out of order.

The invention consists in the improved water-tower attachment combining therein a nozzle attached to the upper end of a hose secured to the side of the ladder of an aerial truck, means for adjusting said nozzle, and

the arrangement and combination of the various parts, as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1.is a side elevation of a portion of a water-tower with my improvement attached thereto. Fig. 2 is a front elevation of Fig. 1, looking from right to left, only a part of the hose and part of the adjusting mechanism being shown. Fig. 3 is a sectional view on line a", Fig. 1; and Fig. 4 is a sectional view through line 1 Fig. 8.

In said drawings, a represents a ladder of an aerial truck, secured thereto in the usual manner, the connection and the truck not being shown in the drawings. To the side of the ladder is adj ustably secured a hose 1), and to the upper end of said hose a nozzle 0, pivoted atc to bracket d, the latter extending from and being secured to ladder ct. The outer end of said nozzle is threaded and adapted to connect with another line of hose or an extension-nozzle. The nozzle 0' is also provided on its under side with lugs e e, to which are secured the Wire ropes f f. The lower ends of said ropes are attached to rods 9 g, having their lower portions threaded (both in the same direction) and adapted to engage internally-threaded hubs 'n 0, carrying gearwheels h h. The hubs n 0 have on their lower ends a reduced extension at 0', adapted to revolve in frame 7a, which latter is secured by bolts or in any desired manner to ladder a. The hubs, with their extensions, are kept in place by collars n 0 as shown in Fig. 4. The upper portion of rods g g are squared, as at g 9 to prevent their turning when the gearwheels are operated, and are guided by passingthroughcorrespondingopeningsin bracket 70, the latter being secured to frame 7t and ladder a, as shown in Figs. 1 and 3. To hub 0 is also secured ahand-wheel tfOI operating the adjusting mechanism.

The operation of my device is as follows: By rotating the hand-wheel c' the gear-wheels h h are caused to revolve in opposite directions and by their internally-threaded hubs n 0 produce an opposite vertical motion to each of the rods 9 g. mitted to the nozzle 0 by means of the wire ropes ff, thus allowing the said nozzle to be raised or lowered and to be held in any desired position.

I do not intend to limit myself to the con This motion is Mans struction shown and described, as various changes can be made without changing the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. In a water-tower, the combination, with a ladder, of a hose adj ustably secured to the side of said ladder, a nozzle connected to said hose and pivotally secured to said ladder, threaded rods arranged at the foot of the ladder and parallel therewith, wire ropes'connecting said rods with the said nozzle, and gear-wheels controlling the motion of said rods, all said parts being arranged and adapted to operate substantially as described and set forth.

2. In a water-tower, the combination, with a ladder, of a hose adj ustably secured to the side of the ladder, a nozzle connected to said hose and pivotally secured to a bracket on said ladder, gear-wheels adapted to mesh into each other, threaded rods adapted to be operated by said gear-Wheels, and Wire ropes connectin g said rods with the nozzle, all said parts being adapted to operate substantiallly as described, and for the purposes set forth.

3. In a Water-tower, the combination, with a ladder, of a hose adj ustably secured to said ladder, a nozzle connected to said hose and pivoted to said ladder, gear-Wheels meshing into each other, a frame secured to the foot of the ladder and serving as a support for said gear-wheels, rodsprovided on theirlower portions with threads and adapted to be operated by gear-wheels, guides for said rods,a hand-wheel operating said gear-Wheels,and Wire ropes to connect said rods with the nozzle, substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of Au- 2o gust, 1801.

THOMAS RAWSON.
