UNITED STATES ANDREW M. PATRICK, OF LONG LANE, 'MISSOURL IMPROVEMENT IN FIREMEN.S AND BUILDERS ELEVATORS.
Specification forming part of Letters Patent No. 123,642, dated February 13, 1872.
Specification describing a certain Improved Firemens and Builders Elevator,invented by ANDREW M. PATRICK, of Long Lane, in the county of Dallas and State of Missouri.
Figure 1 represents a vertical section of my improved elevator taken on the plane of the line 0 c, Fig. 2. Fig. 2 is an end elevation of the same. Fig. 3 is a detail face view of one of the extension-frame sections. Fig. 4. is a vertical section of the same on the line 70 70, Fig. 3. Fig. 5 is a detail transverse section of the frame on the line 0 k, Fig. 1.
'Similar letters of reference indicate correspending parts.
This invention relates to a new extensible apparatus for elevating firemen and their material to any desired height and in any suitable position; and consists in the combination of an extension frame and operating-windlass with a suspended box having a perforated bottom, as hereinafter more fully described.
A in the drawing represents the supportingframe of the machine mounted on wheels, not shown, or supported directly on the ground, downwardly-projecting prongs a to preventing itfrom slipping. In this frame are the bearings of two shafts, B and O, which are united by two sets of gears, b and (1, one for speed, the other for power. One set is thrown out of gear when the other is to be used. Power can be applied by means of a crank, e, to the upper shaft B, and thence transmitted to the lower, 0, which is a windlass for elevating the weight. D is a frame pivoted at its lower end to the frame A, and provided with braces ff that keep it in an elevated but inclined position. A horizontal windlass, E, has its bearings in the frame D. FF are the several sections of the extension frame, which is held against the pivoted frame D and between projecting ribs 9 g at the sides of same. Each section F consists of two side bars, 71. k, that are connected by proper transverse pieces, '5 i, as shown in Fig. 3, and has sockets 7' 9' at the lower ends of its bars h, for the upper ends of the same bars of the next section below to fit into. When a section, F, has been placed against the frame D it can be elevated by means of the windlass E, from which a rope or chain, 1, passing over a pulley, m, at top of D, connects with such section. When the section has been sufficiently elevated, another section is applied to its lower end and connected with the windlass E, and further elevated until the desired height has been reached. The uppermost section F has friction-rollers n n at its top part, to move easily against the face of a building. The windlass G is connected with a rope, 0, which passes over a pulley, 19, that is suspended from the upper part of the uppermost section. A box, G, can be suspended from this rope 0 and raised to suitable height by means of the windlass 0, either to elevate firemen and their material, such as hose, 850., to where they can be of most use, or to lower inmates of burning houses and their property.
A hole is in the bottom of the box. The hose is drawn through it, and thereby in the most convenient position for the person occupying the box. The apparatus can also be used for elevating and lowering building materials and for other suitable purposes. H is a screw fitted to the frame A and bearing on a lever, I, which serves as a brake against the windlass 0. By means of the screw H and brake the loaded box can be arrested at any suitable height.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent The sectional extension frame F F, arranged in combination with the pivoted frameD, windlass E, and with the windlass O, rope o, and perforated box G, substantially as herein shown and described.
