DOOR-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 749,108, dated. January 5, 1904.

l pplication filed March 11, 1903.

To all whom, it 1nay concern.-

Be-it known that I, LOUIS A. SHEPARD, a citizen of the United States and a resident of the borough of Brooklyn, city of New York,

State of New York, haveinvented certain new and useful Improvements in Door-Operating Mechanism, of which thefollowing is a specification. 7

My invention has for its object the provision of an improved door-operating mechanism for railway-cars which is characterized by lightness and ease of operation and at the same time by the great strength and power with which it holds the doors in a closed position. It furthermore provides an improved fulcrum by which the toggle arm or link may be united to the operating-beam of the doors, which fulcrum is capable of being readilyremoved or detached from the said beam.

The scope of the invention is defined by the appended claims.

In the drawings .which accompany this specification, Figure'l is a broken plan View illustrating my invention, together with a portion of a car-frame and the doors to which it is applied- Fig.2 is a section on line 2 2 of Fig. 1, showing in addition certain adjacent parts of the car which are omitted from Fig.

:1; Fig. 3 is a. transverse vertical section taken through the axis of the toggle-joint. Fig. 4 is a detailview showing a bottom plan of the toggle-joint; Fig. 5 is a detail plan view showing the fulcrumpreferably used by me, together with portions of the door-operating beam. and toggle-arm. Figs. 6, 7, and 9 are enlarged top,side,and end views, respectively, of the fulcrum of Fig. 5. Fig. 8 is a sec tional view of a modified form of fulcrum, and Fig. 10 is an end view of one of the members of the said modification. I

The door-operating mechanism is preferably to be used in the operation of the doors used in railway-cars for the carriage of coal and other materials which are self-discharging.- Such doors are often arranged in pairs 1 1 and may be operated by a single beam 3, as shown in Fig. 3. Furthermore, opposing pairsof doors may be operated by a single mechanism, as the doors 1 and 2r (Shown in Figs. 1 and 2.) v

'Myinvention when the doors are arranged in pairs comprises the operatingbeams? 3,

.tance from the said axis or pin 8.

which are rigidly securedat each end to the as shown in Figs. 1 and 2,-or it may be com-- posed oftwo or more parts secured together and to the beam 3, as the fulcrums of Figs.

5 to 9 or as the fulcrum shown and claimed thereby drawing .the beams 3 toward each other and opening the doors. The said means may be of any approved construction, such as a link 7, connected at its lower end to the pin 8, forming the axis of the togglejoint, andat its upper end'connected to an arm 9, fixed upon thehorizontal shaft 10.

'The said shaft is preferably jou-rnaled in bearings 11 and;l2, supported by the center sill l3 and side wall 14 of the car, as shown in Fig. 1. One end of the said shaft carries a notched plate 15, adapted to be engaged by the'locking-dog 16, and thereby firmly held.

In order to keepmhe axis 8 of the togglejoint in a vertical path when raised by the arm 9 and link 7, I provide each of .thetoggle-arms with a laterally-extending lug or projection 18, which is situatedat some dis- Ve rtical guides are provided for the said lugs and may consist of angle-beams 19, as shown. In

place of the. said beams, however,I may substitute therefor channels, or instead of using a single angle, as shown, a pair ofangles may be used, between which the lugs 'may operate. It is obvious that any other form oi vertical guide may be used, however.

It is evident that in case single doors'l and Correction in Letters Patent No. 749,108-

What I claim,an'd'desire to secure by 2 are arranged opposite each oth'er the beams 3 may be dispensed with and ihe toggle-arms 6 applied directly to the doors.

The fulcrum illustrated in Figs. 5, 6, 7, and 9 is composed of two similar complementary pieces or members 21 22, each of which carries a jaw 23, which together form the fork to which the toggle-arm is to, be. secured. The ends of the pieces 21 22 opposite the jaws 23 terminate in the flattened end portions 24, which are perforatedand adapted to be clamped by a rivet or other suitable means against opposite'faces of the web of the. flanged bea|n3.; The intermedi ate or body portions'oft-he members 21 and 22 are so shaped as to-providedeep grooves or recesses 26, which receive the flanges of the I-beam3, These portions are also provided with sloping'shouldersior angular projections 27.27, which abut"and interlock when'the members 21"and 22 are brought' together.

Each of the'j-aws 23 is provided with a perforated" boss 28. These bosses occupy similar relative positions with respect to thejaws, andwhen the members 21and 22 are brought together the bosses 28 abut. against eachother and may be secured in this position by a rive't or bolt29 passing through their centers, as best seen. in'Fig. 6. The jaws 23'are also bored with pin-holes ,30 for the purpose of securing the toggle-arm'theretm By this con struct-ionwhen the mem'bers'2l and 22 are fitted togetheraround the flanges of the beam 3 and the rivetsinsertedaveryfirm and rigid union of parts is secured.

p In place offthe bosses 2S and rivets 29 Imay; use ashouidered rivetj3l Figs. 8 and 10,; rigid with one of the jaws 23 and provided with a shoulder 32 and a shank- 33. When 'the members 21 and 22 are brought together,

the shoulder 32 bears against the opposite jaw 23', while the shank'33 passes through an aperturein the latter jaw and may be riveted, as shown in'Fig -S; L I
