METAL GAR DOOR.

Application filed March a, 1926. Serial menses.

This invention relates to a metal door for railway cars and the like, and concerns itself with a structure which is simple in manufacture in that it comprises but few parts and requires a much smaller number of rivets than heretofore used for assembling the same, which is sufliciently light to meet the requirements of common practice yet sufficiently rigid to prevent flexure or weaving.

The invention comprises the novel structure and combination hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numorals refer to similar features in. the different views,

Fig. 1 is a front elevational view of a metal car door involving this invention;

' Fig. 2 is a broken sectional view upon the line HII of Fig. 1; a

Fig. 3 is a broken sectional View upon the line III-III of Fig. 1;

Fig. 4 is an enlarged fragmentary elevational view showing the upper corner construction;

Fig. 5 is an enlarged fragmentary elevational view at the, juncture of two panel seei Fig. 6 is a fragmentary perspective view showing the manner of connecting the rein forcing parts;

Fig. 7 is a fragmentary sectional view of a modified structure illustrating a. lower roller support in the door.

Referring now. to the drawings, it will be observed that the illustrated door comprises a plurality of panel sections 1, 2 and 3. The upper and lower margins of the panel 2 are outwardly effect as indicated at 4 in Fig. 3, and the lower margin of the panel section 1 and the upper margin of the panel section 3. are correspondingly offset. These ofi'set portions of the panels are riveted together by rivets 5. These offset portions tend to rigidify the door.

It will be notedthat the offset margins of the, anal sections 1, 2 and 3 terminate'a short the panels in order to provide space for rigid1fying members 6 which extend along ,lateral margins of the. door." Each of these rsilgidifyiiig members 6 is in the form of a flange 10".

istance from the lateral margins of channel member having a web portion 6 spaced from the plane of the door, and laterally extending attaching flanges 6 riveted to the door. At the upper margin of the door there is secured a similar rigidifying member 7 of channel-like formation'having an intermediate portion 7 spaced from the door and laterally extending flanges 7 through which the attaching rivets extend. Suitable roller. supporting brackets 8 are attached at the upper corners-of the rigidifyin'g members 6 and 7 so as to overlap the joints.

The lower margin of the panel 3 is outwardly oifset as indicated at 9 in Fig. 3 and a rigidify ing channel-like member 10 having upper and lower attaching flanges 10 is riveted to the offset portion by its upper A bridging strip 11 extends across the rigidifying member 10 and 15 While it is possible to extend the panel 3 downwardly suficient so that the rlgidify- 'ing member 10 may 'be riveted lay-both flanges to the panel as shown in the. Elliott Patent No. 1,330,143, the present structure facilitates the manufacture and assembly of the door and at the same time it increases the section modulous of the lower part of the door.

In order to further stifien and brace the door, the channel members 6 are provided with hoods or' envelopes 12 that overlap the ends of the transverse channels '7 and .10 andthe oifset joints 4 of the pane] sections as shown in Fig.- 6. The members 6 are preferably formed by pressing a flat sheet. of metal in a die which is so constructed at intervals that the proper -hoods 12 are formed for fittin over the to and sides of the channels 7 and 10; an the offset joints 4. The'hoods 12'are riveted to the tops of the channels 7 and IO'and to the joints 4 as indicated at 5. I

In order to prevent l ading from the vertical spaces nnder the. channel mom-.- her 6" through the o'fiset joints of the panel sections, guard plates 13 are positioned to close the entrance of the space defined by.

75 riveted. to the lateral margins. thereof.

the offset joints to the vertical channel mem- .7105

bers 6. It be noted-that an end of each guard plate 13 is rivete'd'to the offset ends of adjacent panel sectionsf-whilethe otherend extendsmto the vertical chamber of the channel member 6.

The completed door is provided with'the usual front edge angle 14 and the rear edge supported at the lower end of the door, andrunn ng upon a track 17, the outer roller 7 bracket '18 and the track having overlapping parts 19'and 20.

a It will be appreciated that the a door is made of few parts and requires less riveting than many other doors of this type. Moreover the connections between the transverse reinforcingparts and the vertical members 6 secure a rigid joint that tends to rigidity that the door can be very easily and economically manufactured.

We are. aware that many changes may be made and numerous details of construction may be varied through a wide range with out departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon, other: wise than necessitatedby the priorart.

We claim as our invention:

1. In a metal car door, a plurality of panel sections having their adjacent margins out wardly offset and secured together, and channel-like reinforcing said channel 'members communicatin the structure. It willalso be appreciated members secured to the lateral margins of the panels and having laterally projecting hoods enclosing the ends of said offset margins.

2. In a metal car door, a plurality ofpanel sections having their adjacent margms oifset and secured together, channel-like reinforcing members secured to the lateral margins of said panel sections and having ofiset hoods overlapping said offset margins and guard plates at o posite ends of sand oil'set margins to exclu e ladingfrom entering said channel-like reinforcing members.

3. In a metal car door, a panel having an intermediate outwardly oflfset portion, channel-like reinforcing members secured at an angle to'said ofi'set portion, the interior oi wit said ofiset portion and guard plates in said oilset portion to exclude lading from said channel meinbers.

4. In a metal car door, a plu'rality of panel sections having ad'acent margins outwardly offset and secured. together, reinforcng transverse channel sha ed members at the upper and lower margins of said door and vertically. extending channel-like re inforcing members secured to the lateral margins of the panels and having laterally inwardly rojecting hoods enclosing the ends of said oifset portions.

In testimony whereof we have hereunto subscribed our names;

EUGENE J. FEHR. WILLIAM w.. DARROW.
