GEORGE B. READ, OF BLOOMINGTON, ILLINOIS.

ELEVATOR.

To all whom it may concern:

Be it known that I, GEORGE B. READ, citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Elevators, of which the following is a specification.

This invention relates to improvements in elevators.

One of the objects of the invention is to provide an elevator designed to be composed of sections adapted to be united to extend the same to any desired length.

The invention includes means for joining the separate sections and particularly refers to structural formation of metal parts from which the sections are constructed to the end of strengthening the same against transverse, torsional and other strains.

The invention also includes reinforcing longitudinal frame pieces disposed in a relation to the body of the elevator to strengthen it and with relation to flight conveying mechanism to carry conveyer chains in a manner to take the brunt of wear and to re duce the noise of operation of such flight conveyers.

Referring to the drawings, Figure 1 is a side elevation showing one full section and the end portion of an adjoining section, the full section being made sectional on the line aai of Fig. 2; Fig. 2 is an end view of one of the sections, and Fig. 3 is a plan view of the bottom portion of a section showing the corrugated formation of the same.

In the drawings, 2 refers generally to the elevator sections; 3 refers generally to the elevator trough.

4 refers generally to the transverse bottom portion of the conveyer and is properly spaced apart from the conveyer trough to provide space within which the return flights are carried.

Parts 3 and 4c are designed to be formed of sheet metal. The upper edges of trough 3 are adapted to be turned from a vertical line and in substantially the same manner as at 5 for the purpose of reinforcing the upper edges thereof. The complete sectional trough may be formed of a single piece of sheet metal, the same being shaped substantially in rectangular form with the lower longitudinal corners thereof having the angular olfsets or channels 6, said channels running the full length of each section, the channels of each section adapted when Specification of Letters Patent.

Application filed December 15, 1911. Serial No. 665,918

the sections are united to form continuous channels the entire length of the elevator. The channels 6 thus formed in sections, strengthen the same, especially against transverse strains, and effect a reinforcementof the metal sections.

7 are wood strips or bars set into and eX- tending the length of channels 6, which being properly secured therein, serve as a general reinforcement of the metal sections and also serve to support the conveyer flight chains in their travel, taking up the brunt of wear and serving to reduce noise in the operation to the minimum, of the traveling chains.

The transverse bottom portion 4 is designed to be of sheet metal and has the downwardly, laterally and upwardly turned portions forming the channel portions 8, such channel formations serving the same functional purpose as described in connection with channels 6 of trough 3.

99 are wooden strips or bars set into and extending the length of channels 8, serving the same functional purposes ascribed to bars 7 of trough 3.

10 are channel plates adapted to connect trough 3 and the transverse bottom portion 4, and are connected to the said trough and transverse bottom portions, and likewise opposite channel portions 10 by means of rods as 11, as best illustrated in Figs. 2 and 3, and by means of bolts as 12 connecting said channel portions with the trough portion. V

The channel plates 10 serve as reinforcement against transverse, torsional, and other strains that would tend to destroy the desired rectangular lines of elevator formation that is desirable and necessary to effect the best results. As many such channel portions 10 may be employed as are found necessary to properly strengthen the sections. The outer edges of the channel plates of each section are serrated as at 13 and contiguous edges of each plate are bent outwardly from a normal vertical plane so that they bear relatively a staggered relation (as best shown in Fig. 2). I have designated these staggered portions as 14. The staggered portions of end channel plates 10 upon the meeting ends of sections are bent, each matching relatively in opposite directions so that when the sections are brought together, they will pass to a contact, the outer edge of each staggered portion with the inclined face of the body of the contiguous section,

thus serving when the sections are united, as by means of the bolts 15 engaging perforations of the respective end channel plates, to form a continuous interlock throughout the length of said channel plates, serving to reinforce the bolt connections and the elevator as a whole against transverse, torsional or other strains. Also, by means of the staggered relation of the connected channel plates and the angular disposition of the same, any lost motion or looseness between the sections may readily be taken up through and by means of the bolts 15 drawing the staggered parts into close contact.

In the main figures illustrative of the structure of the sections, I have shown the metal bottom portions respectively of the trough portion 3 and the transverse portion 4 as of plain, fiat metal, but in practice I may desire to corrugate these bottom portions, as shown at 16 in Fig. 3, either in straight corrugations or in herringbone style, the purpose of such corrugated formation being to stiffen or reinforce the metal of the elevator sections.

What I claim is:

1. An elevator body, comprising in combination, sheet metal trough and return members and means for spacing said membersapart, each of said members consisting members and means for spacing said members apart, each of said members consisting of a bottom portion, longitudinal channels formed on each edge thereof by downwardly, outwardly and upwardly bending the edge portions of each member, filling blocks fitted to said longitudinal channels to entirely fill the same and project above the tops thereof, and transverse bolts extending through said spacing means, downwardly and upwardly turned portions, and said filling blocks, whereby to form a unitary structure.

In testimony whereof I have aflixed my signature in presence of two witnesses.
