BRIDGE-GATE.

Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed May 12, 1910. Serial No. 560,948.

To all whom it may concern:

Be it known that I, CASPER FAUsT, a citizen of the United States, residing at Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Bridge-Gates; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved automatically operated bridge gate for use in connection with swinging bridges for closing the road way approach to travel when the bridge is turned away from its approach.

The object of the invention is to provide a simply constructed and reliable gate which is automatically closed on the opening of the bridge and opened on the closing thereof.

Another object is to provide simple and eflicient means for automatically locking the gate in closed position operable by the opening of the bridge and for unlocking it on the closing of the bridge.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a top plan view of a draw bridge and the adjacent roadway equipped with this improved gate the bridge being in closed position; 2 is a side elevation with the bridge shown in open position and the roadway closed by this improved gate; Fig. 3 is a bottom plan view with the bridge in closed position; Fig. A is a similar view with the bridge in open position; Fig. 5 is a central vertical longitudinal section with the bridge in closed position; Fig. 6 is a similar view taken on line 6-6 of Fig. 4:; Fig. 7 is a transverse section taken on line 77 of Fig. 25. Fig. 8 is a similar view taken on line 88 of Fig. 3. Fig. 9 is a perspective view of one form of the gate detached. Fig. 10 is a side elevation of the preferred form of gate with parts broken out. Fig. 11 is a horizontal section taken on line 11 11 of Fig. 10. Fig. 12 is a vertical section thereof. Fig. 13 is a perspective view of the blade holding member. Fig. 14: is a similar view of one of the blades detached.

In the embodiment illustrated A represents a portion of a draw bridge of the type which revolves about an axis located at its center and has ends which are formed on curves which are concentric with said axis, said curved ends being preferably provided with a flange B which extends in the same plane with the upper face thereof and is adapted to overlap a similar flange G formed on the lower face of the abutment D which is formed with a curve and also arranged concentric with the axis of the bridge. The construction of the abutments D of this well known type of bridge depends upon the exigencies of the situation and they may be of masonry, open trestle work or any other desired construction.

A vertically movable gate 1 is here shown which rises and falls through the bridge floor being preferably constructed in the form shown in Figs. 10 to 1 1 of the drawings, and which will be hereinafter described in detail and having upwardly projecting members 2 which are longitudinally spaced apart as at 3, and are adapted to slide through openings as A in the bridge. A loop 5 depends from the bottom of the bridge and is designed to limit the downward movement of the gate 1.

Two longitudinally extending laterally spaced supporting

bars

6 and 7 are mounted on transverse sleepers '8 and 9 on which the bridge is supported. A rod 10 is revolubly mounted in the

bars

6 and 7 with the opposite ends thereof projecting beyond the outer faces of said bars and

crank arms

11 and 12 are secured at one end to these projecting ends of said rod for a purpose to be described. A pinion 13 is fixed to said rod intermediately of its ends and meshes with a rock bar 14 slidably mounted on the lower faces of the sleepers 8 and 9 and by means of which said pinion is rotated and motion imparted to the gate 1 as will be hereinafter described. This rack bar is provided on its inner end with an upwardly projecting stud 15 on which is preferably mounted a roller 16 for engagement with a member carried by the movable bridge member A. The lower edge of this bar 14 near its outer end is provided with a recess 19 the walls of the opposite ends of which are arranged to engage one of the supporting members for said bar to limit its sliding nnweinent in opposite (ii-- rections. (Jain links :20 and 21 have the anus thereot pivotally connected with said gate 1 in any dot-sired, manner. These linlis are earl: provided with longitudinally extending slots as termed a: the base oi the cams thereot and with which are engaged headed studs as 23 carried by the free ends of the cranlt arnis ill and 12 and by in ans ot which the gate raised and lowered. The opposite ends of tl linlcs Q0 and are provided with com; .atircly short cl ni ated slots as I t: 24-, which are eiigaggeil with headed studs as 25 pro eeti n laterally from the outer faces of the ba s (2 and 7 and on which antifriction rollers as .26 are preferably n'iouuted to provide for the ready operation of the links. ll hen the gate is in raised or operative position the cranl; arms 11 and i2 are a. little vast the center in rat went with n nor ends of the slots ant hie gate is thereby automatically loclted in operative posi tion. The gate is released by the closing or the draw bridge.

The gate 1 in y be constructed as shown in Fin. E) from a sin "metal bar or p ate having transrerselv (,i'\l\ :,ll(llll: cut out por tious E} to town the blades or liner-rs which are des zncd to move yerti all ii spared, openings 4- arranged transversely or the bridge and in longitudinal alinelnent with each other. The; do, however preterahl i' eonslrurted as in Llo't two lair:v 33 and t-t of any sni material preferably o't' metal which are ranged side by side and connected together by a plurality of rivets as 3? which are ar ranged on opposite sides of longitudinally spaced spacing blocks av 36 arranged betweei said bars 33 and 3st at suitable intervals to term openings for the reception of upright removable slats 3? to be described. The rirets Xi'fi'fitl throw the bars ieir lowe eds s and a iacent able i and 34 near til opposite sides of the pacing blocks 3'3 to torn'i seats tor the renio-whle slats ill. The blocks 30 may be of any desired or suitable thickness i i and sprced apart any desired distai'ice to acconnnodat plates of any de sired width and tlies blocl's are secured in position by rivets as of) whi 1h extend transversely through the upper ends of said. blocks, and the upper edges of the bars 33 and El whereby in connection 1* 'th the rivets 35 said bars are held securely together. tt 'wo of these spacing-3; blocks 36 arranged at suitable points, project beyond the lone edges ot the bars and 3st and are prawided with apertures as 39 for connection with the links .20 and 21. These bars and Set may be of any desired length according to the width of the bridge to which, the gate is designed to be applied.

The slats 37 are constructed as shown in Jag. 14- from rectangular plates preferably ha? no; the opposite corners of one at to it'orni seats 4-0 and. ll tor enl with the transversely arranged. rivet.) between the bars 2? and 34: whereb' said slats are held .in position against rt wnward inorenicnt. These slats 87 are preferably made to tit tightly l ietwcen said bars 33 and it to prevent their accidental di ngagg'einent therefrom but which may be removed when necessary to supply a new slat.

in the. form shown the removable bridge er It is provided on its lower face ad- 121 rent the curved end thereof with two transversely extending spring members 3O 11 9 1 1 p J! t. e, I]: 1. lilo o1 1101 are in tie iollll o. ,oLiGUL- .l plates rigidly secured at a point ninlray the ends thereot to said movable incini bar It with their opposite ends tree to enr'age the roller iarrynre stud 15 on the 111- err end ot' the rack barle' These

members

30 and 31 are ill arranged in longitudinal moment and the inner f. thereot are spaced, apart a d suh nent to perctly opposite the space heween the member? 30 and 31 and the curved outer tat-e thereof l'ieing adjacent said incinbors 30 and 31 and over which the roller 15 is designed to operate and which also serves as a guide for said roller in it passage from one of the members 230 and 31 to the other.

in the ope 'ation of? this improved gate the parts being; in the position shown in Fig. 3 with the roller 16 arranged l'i'etwoen the inner ends of the members Pa and 31 the inoyanent of the member A in either direction will cause the roller 16 to be engaged with the outer face of one of said n'ien 30 or 31 whereby the *ack bar is torced rearward ly thereby rotating; the pinion 1 a sutlicient distance to more the gate 1 upwardly through the floor of the bridge by means of the cam links 20 and 21 and the crank

arms

11 and 12 connected with the rod 10 to which said pinion is fixed. Yr'hen the movable bridge member A is swungback into closed position the outer face of the spring inei'nber 30 engages the inner face of the roller carrying stud 15 on the rack bar 141; and the continued inward inoveniei'it of said member A causes the rack bar to be moved forwardly thereby turning the pinion 13 and lowering; the gate 1 into the position shown in Fig.

From the foregoing description taltcn in connectimi with the accompanying drawings the construction and operation of the invention will be understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantagcs of this invention as defined in the appended claims.
