Description
EDVIN H. GRANIl-IAM AND JOI-IN B. CGRNWALL, OF MOLINE, ILLINOIS, ASSIGNORS T0 BARNARD AND LEAS MANUFACTURING COI'IPNY,
CORPORATION 0F ILLINOIS.
ELEVA'IOE.
To all u1/0m it may concern.'
Be it known that we, EDWIN H. GRAN- 'ri-IAM and JOHN B. CoRNwALn, both residing at Moline, Rock Island county, Illinois, have invented certain new and useful Improvements in Elevators; and we hereby deelare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.
This invention is a novel improvement in elevators especially designed for use by eine ployees in factories in passing,` from one floor to another, and its object is to provide an endless elevator which can be operated at very little cost, and by which individuals or packages can be lifted from one floor to another, or lowered from one fioor to another, quickly and easily.
Generally speaking the apparatus com prises aI stout endless belt 'to which are fastened, at proper intervals, platforms large enough to carry a man. This belt runs over broad pulleys at the top and bottom of its run and is guided by means of a substantial steel frame connecting the bearings in which the head and foot pulleys are j ournaled. rit convenient distances above the platforms metal loops are attached to the belt for use as hand-holds.
The present invention has particular reference to the construction of the steps or platforms on which the persons stand while ascendingor descending. These platforms are arranged in pairs, one platform in each pair being adapted for use on the ascending side of the belt and the other at the descending side thereof; such platforms being` attached to brackets, which are pivotally connected to each other, and are also connected with the belt in such manner that the brackets can pass around or over and under the pulleys, at the head and foot of the belt run without binding or j arring.
We will first explain the construction of the elevator in detail with reference to the accompanying drawings; and then concisely state in the claims the parts and features of construction wherein the present invention resides and for which protection is particularly desired.
l/Vhile the invention as described is intended primarily as an elevator for operatives or workmen in mills and the like; it

is .also readily adapted for raising and lowering objects from one floor or level to another.
In the accompanyingl drawings-Figure l represents a side elevation of the elevator, partly broken away. Fig. 2 is a side elevation of Fig. l, partly broken. Fig. 3 is an enlarged section on line 8-3, Fig'. 2. showing` one of the platforms. Fig. f tlis a side elevation of 3. lfig. is a section on line 5 5, Fig. li, looking in the direction. of the arrow. Fig. G is an enlarged detail.
As shown the elevator comprises an endless carrier or belt l, of leather or other suitable material, which runs over an upper pulley 2 and under a lower pulley The shaft En of the upper pulley may be journaled in suitable bearings in a frame 2b supported in any suitable manner upon the upper floor of the building; and shown as mounted upon an I-beam 2C; while the shaft 3 of the lower pulley 3 is journaled in a frame 3l mounted on the basement or lower floor of the building. The shaft 2a may be operated by means of worin wheel 2d mesh' ing with a worm 2 on a transverse shaft 2f mounted in suitable bearings and provided with pulleys j; which can be driven by a belt (not shown) from a suitable motor.
The foregoing` parts may be of any suitable eonstruction and are not specifically claimed herein. l
The upper and lower frames Q1 and 3b may be connected by pairs of vertically dis-- posed lei-bars il, which bars are set with their channels facingthe edges of the belt, and such channeled bars are used as guides for the platform or step brackets as hereinafter explained.
Attached to the belt l at .suitable intervals apart are bars 5 which may be secured to the belt by rivets or by nuts and bolts as indicated in Fig'. 3. These bars project slightly beyond the side edges of the belt and have on their outer ends studs or jour*- nals 5 upon which are pivotally hung the brackets G, and GX of pairs of brackets that support the pairs of platforms. Each bracket 6, is approximately triangular shaped and stands at right angles to the belt, and each has a short inwardly extending arm 6" which is pivoted on the adjacent stud 5 ,and is j :irovided with a stud 6 on which is mounted an anti-friction roller 7 OF MOLINE, ILLINOIS, A-
that engages the groove of the adjacent U- bar a. Each of these rollers has its tread 'la of such slant or bevel as will conform to?i the slant of the inside of the channel bars d, while its flange 7,
is curved outward and backward t' from the tread or point of contact with the bar; and
the tread of the roller is less in diameter than the inner width of the channel bar e. vrl`his leaves the idle side of the roller tread free from the rear flange of the guide bar,-
thus permitting the roller to turn freely.
rlhe main portion of each bracket. 6, G* projects at the outer side of the belt, and there is a pair of these brackets or braces employed at each side of the belt to support each pair of platforms. rlhe outwardly projecting portions of the brackets G, 6^' are approximately triangular in form, and these brackets are pivotally connected, as shown in Figs. 4 and As shown in side elevation, F ig. 4:, each pair of brackets 6, GX resembles an X, and they are pivoted together at their intersection preferably by forming the brackets G, which would be uppermost at the ascending side of the belt, with a stud 6C that passes through a corresponding opening in the related bracket 6X, which would be uppermost at the descending side of the belt. fand these brackets are held together by means of a washer Gf strung on the stud 6, and a pin 6g translixing the stud. rlhe related opposite brackets 6, 6, in each pair are connected by a platform or step Sa, and the opposite brackets 6X are connected by a platform or step S. lt will be seen that the platforms are arranged in pairs, and as shown the platforms Sa would be uppermost at the ascending side of the belt, where the platform 8 would not be used; and at the descending side of the belt the platforms 8 would be uppermost, while the platforms S` the other; and their supporting brackets are pivoted at their meeting points, so that they may adjust themselves to the changing position of the belt when passing over the pulleys; thus avoiding unnecessary friction and the objectionable falling or jarring of the platforms as they` pass over or under the pulleys.
rl`he operation of our elevator will be obvious from the foregoing description and the drawing, and needs no detailed explanation.
'While we have described a belt as t-he preferred carrier for the platforms. it is obvious that the invention is not restricted to a belt, as other endless carriers could be substituted therefor. Y

which acts as a side guide, j

4. fn an elevator of the character specified, the combination of upper and lower pulleys, an endless carrier running thereover, grooved bars beside the carrier, upper and lower brackets pivotally connected to each other at a point beyond the carrier and ends to said carrier, and devices on the pivoted ends of said brackets slidably engaging said grooved bars.

6. An elevator of the character described comp ising upper and lower pulleys, an endless belt ruiming thereover, and grooved bars beside the vertical runs of the belt; with pairs of pivotallv connected upper and lower brackets, the brackets in each pairl being pivotally connected together in front of the carrier and each bracket being pivotally connected at its inner end to the belt, rollers on the pivoted ends of the brackets engaging the grooved bars, and upper and lower platforms attached to said brackets.
