ELEVATOR-CAB INCLOSURE.

Application led June 21,

This invention'relates to elevator car inclosures and particularly to elevator car inelosures forl freight elevators.

One feature of the invention is to provide an inclosure of the above type that is of rigid construction and which requires a minimum ofl material. Anotherfeature of the invention lies in the provision of a car inclosure of the above type that is made up of standard parts produced on a quantity basis.

Still another feature of the invention is to provide a car inclosure that is readily constructed and installed and which is pleasing in appearance.

Other features and advantages will become apparent from the specification, taken in connection with the accompanying drawings wherein one embodiment of the invention is illustrated.

In the drawings- Figure 1 is a view in front elevation of an elevator car inclosure;

Figure 2 is a view with parts Broken aw'ay taken along line 2-2 of Figure 1;

' Figure 3 is a sectional view taken along line 3-3 of Figure 1; and

Figure 4 is an enlarged detail view of a portion of Figure 3.

Referring to the drawings, the inclosure is designated als a whole by the numeral 10. For convenience of description, the inclosure is illustrated as made up ofthree sides,- namely, the left side 11, right side 12 and rear side 13. According to the preferred arrangement, each side is made up of two vertically extending end panels 14 and one or more vertically extending intermediate panels 15, two intermediate panels being shown. The outer vertical edges of both end panels 14 are joined, as by welding, to vertically extending angle bars 16. The inner vertical edge of each end panel 14 and both vert-ical edges of each intermediate panel 15 are bent in such man ner as to have a'portion 17 in a plane at r1ght angles to the panel and another portion 18 1n a plane parallel to and overlapping the panel (see Figure 4), thus producing the same effect as if these .edges of the panels were reinforced with small vertically extending channels. This type of double bend is utilized in connecting adjoining panels.

sure, the panels making up this side are grouped side by side with the portions 17 of adjacent panels in abutting relation. The

anels are then joined by locking strips 20. hese strips are of across section as shown 1n Figure 4 and are formed by folding over the edges of an elongated flat sheet metal strip upon itself. These locking strips. are slid lengthwise over the portions 18 of the adjacent panels, the strips being formed so as to grip the portions 18 when' the parts are in assembled relation. These strips extend the full length of the panels `as shown in Figure 2. With the locking strips in place, the panels are joined at the bottom by an angle bar 22 and at the top by an angle bar 23, these angle bars being secured to the panels as by welding. The horizontal leg 24 of the bottom angle bar 22 extends inwardly of the car while the horizontal leg 25 of the upper angle bar 23 extends out# wardly of the car. Withl the panels thus connected, a strong and rigid side of the inclosure is obtained. The corner angle bars 16 of the side of the inclosure are secured to the end panels in such manner as to provide right and left angles.

With all three sides made up, they are grouped together, as shown in Figure 3, and joined as by bolts 19 extending through the abutting legs of adjoining right and left angle bars 16. The inclosure is secured to the car platform 26 as by screws 27 extending through the horizontal legs 24 of the bottom angle bars 22. A hole or pocket may be provided in'one of the panels to receive a flush type car switch, such a hole, designated 28, being illustrated as formed in the forward end panel 14 of the right side 12 of the inclosure (see Figure 2).

It is preferred to make the intermediate panels of two different widths. Also, it is preferred to make certain of the end panels wide enoughso that they may be cut to any requiredV width with the remaining end panels of a standard width. With th'ese panels, an inclosure having its sides of any desired widths may be made. It is also pre--l ferred to make all the panels of the same height. Thus, standard panels may be kept in stock and inclosures of any desired size may be assembled from them on short notice. Furthermore, with all panels the same height and with their widths standardized,

the number of different panels to be kept in stock is minimized and these parts may be produced on a quantity basis.

It is preferred that the height of the panels be six feet or slightly above, thus satisfying the requirements of practically all statutes. The vertical corner angle bars 16, however, are extended in height beyond the panels: except under certain conditions which will be explained later. The top portion 30 of both corner angle bars 16 for the right and left sides of the inclosure is bent over as shown in Figure 2. These vertical angle bars are joined by horizontal angle bars 31 connected thereto, as by bolts extending through the bent over portions 30.

The inclosure may or may not be provided with a top, depending upon the requirements of' the particular installation. Where no top is provided, the inclosure may be braced above the panels as by tie rods extending from the horizontal angle bars 31 to the crosshead of the car framework (not shown). The tops, when specified, may be made up of a plurality of perforated sheet steel panels 32 secured, as by welding, to cross angle bars 33. These cross bars are in turn secured to the horizontal angle bars 31, as by bolts 34 and clips 35. The front top panel may be set back from the opening a certain distance, as shown in Figure 2, where building regulations require it. Where sheaves are mounted on the crosshead Aof the car framework, it is preferred to provide a solid top center panel with bent up sides to form a pan to protect the car from oil and grease that may drop from the crosshead sheaves and boxes.

If it is desired to have the car inclosed to a greater height than that provided by the solid panels 12 and 14, additional side panels 36 may be provided. Ih'esej panels may be of perforated sheet steel secured, as by welding, to horizontal angle bars 37. At-

their ends, these panels may be secured, as by bolts, to the corner angle bars 16. The lower angle bars 37 may bejoined to the top angle bars 23 of the solid panel sides,l as by bolts. Also, the top angle bars 37 of the right and left side additional anels maybe secured, as by bolts, to 'tile angle bars 31. Where a top is provided, the top angle bar 37 of the rear side additionalA panel may be secured, as by bolts, to the back cross angle bar 33.

In case of a small inclosure with no additional side panels or top, it is found that the inclosure may be braced sufficiently by connecting the top angle bars 23 of the right and left sldes to the sides of the car framework without extending the corner angle bars 16 the additional height. It is preferred to provide this connection for all arrangements of the inclosure and also to eonnectangle bars 31 to the lsides of the car framework where the corner angle bars are extended.

It will be seen that, with the above arrangement, the rear side 13 may be easily removed at any time without requiring any changes to be made in the sides 11 and 12. Furthermore, the inclosure may be made up in the first instance of only two sides, or even only one side, if such be the requirements of the particular installation. The inclosure may be packed for shipping with the panels separated or with the sides assembled, as occasion demands. Where the separate panels are shipped, the sides may be assembled on `the job by means of bolts instead of Welding. It will be seen that the panels are of very simple construction and therefore can be easily made at a minimum cost. Furthermore, the sides may be assembled in a minimum of time by use of the locking strips 2() owing to the fact that this method of assembling eliminates a large percentage of the welding formerly required. It is to be noted that the channel-like arrangement of the vertical edges of the adjoining panels makes a very strong construction and together with the steel locking strips makes up a rigid steel inclosure with a minimum amount of material. f

As many changes could be made in the above construction and many apparently Widely different embodiments of this. invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
