sAFETY-GARD FOR cARs.

T0 all whom 'it may concern: i

Be it known that I,MART1NMEYER, a citizen of the United States, residing-at Omaha,

in the county of Douglas and State of Nef` braska, have invented certain new and useful Improvements in Safety-Guards for Cars, of which the following is a specification. Y

This invention relates to improvements in safety guards for cars, found especially useful for street car purposes, and refers to a re-` liable and convenient means,iunder control of the employee in charge, for allowing passengers to depart safely from or enter the car. Devices heretofore provided for this `purpose have consisted of gates occupying iloor space, or which rotate in a manner to be obtrusive, and have not proven entirely satisfactory.

The present invention has for its `principal 1 object the provision of a frame or frames, or parallel bars extended longitudinally of the car and to be disposed in front of the platform, platforms or assage ways which define exit ways to 'or' om the car, the same to hang dependably from a ivotal support located at or near theroof of) the car, and to be under the. control of the employee in charge, so that the guard above mentioned, may be readily swung upward or downward to allow or prevent entry or exit, and thereby to prevent accidental injuries.

Another obj ect is to provide a means which will permit a control` of all of the passage ways by the conductor of a car or other person in charge, wherever he may be located.

Another'object is to provide a closure for the passage ways of cars, which may beV operated to move the closure in a direction which will be unobtrusive to passengers or others.

The invention includes a construction and arrangement of holding and lifting arms and their mounting, found to be convenient, and describes devices comprisingrf the safety guard having the lightest weight possible but which will have the required strength for its uses and operation, which may be economically constructed, easily operated, and which will be durable.

The invention consists of the novel construction and arrangement of parts as described herein and in the appended claims, and illustrated in the accompanyingV drawing, wherein,

Figure 1 represents a side lelevation of an l Specification of Letters Patent. Application filed. January 2,` 1908. `Serial No. 408,868.

Patented Oct. 6, 1908.

open or summer street car with my ered or closed7 position, the figure being broken. a Fig. Zis a rear end view of the oar and parts shown in Fig. 1, the broken lines illustrating the relative position of the guard when raised or elevated. Fig. 3 represents a side view of a .closed or winter car with the safety guard mounted thereon, and Fig. 4 is an end view of thecar and parts shown in Fig. 3. Fig. 5 is a detail relating to Figs. 3 and 4 to show sprocket connection and rotating means. Fig. 6 is a detail to show preferred construction of the guard-rail or fender. .-Figs. 7 and S are details to clearly show pivotalconnection between the arms referredy to.

Referring now to the drawing for a more particular description, numeral 1 indicates a street car, numerals 2. and 3 indicate the front and rear platforms thereof, and 4 indicates the roof, 5.the deck, 6 the floor, 7 the kpassenger seats, 8 the platform-step; numerals 9 and 11 indicate, respectively, the wire net-work .and the running board17 or side stepused upon summer" cars, said network being secured along and upon the blind side of the car, and the side step extending the whole side of the open part of the car. For .purposes of the invention I employ a guard member 12, extending longitudinally of the car in front of the passageways 10 the guard-member 12 mayconsist of any suitable fender, as a frame-work composed of the parallel bars 13, 14 and 15 joined at or intermediate their ends, preferably, to occupy a single plane the framework thus described has been constructed to providelongitudinal `grooves a in bars 13 and 14 within which grooves, panels -16 may be conveniently inserted as indicated in the drawing, said panels causing the frame work to be more visible and more readily distinguished than open frame-work, and useful for advertising or sign displays.l

I providelsupporting-brackets 17, secured externally of the car and above the exit-ways these brackets being fastened, preferably, closely adjacent the side eaves of the car, and in sup orting-brackets 17 is pivotally -mounted t e rotatable supporting-rod or shaft 18. Rigidly secured to s aft 18 and disposed in alinement with each other are liftingarms 19, preferably bent outwardly and longitudinally, and therefore being bowshaped from their pivotal mounting upon shaft 1S to their outer ends; these arms have been used in pairs to advantage, substantially as U-shaped arms, to combine strength with lesser material, the lower part of the U,

however, being angular as thus used, each' pair of arms 19 furnish, at the junction of their lower ends, a pivotal mounting for the upper end of one of the dependable supporting-arms 20. Y

The lower ends of supporting-arms 20 are secured to the frame or guard-member 12, and they are each provided with a transverse sleeve 21 upon their upper ends, and I provide a keeper formed as a detaining-plate 22 disposed parallel with sleeve 21, and having a length greater than the distance apart of the pair of lifting-arms 19 and disposed to overlap and make contact with the lower or outer ends of said lifting-arms, the function of this particular construction being, that a keeper 22 will prevent any outward swinging movement of a supporting-arm when the guard is in a lowered position unless a movement is communicated to lifting-arms 19, and thereby reventing an outward swinging movement o` any part of the frame or guardmember 12, unless said frame or guard moves as a unit and carries with it all of the arms, as a united structure.

Having described the principal parts, operation of the safety guard will be readily understood. It is intended to be under control of an employee who isnin charge of the car. When the car is moving, the. guardrail is in a lowered position. lf a passenger wishes to leave the car, the person in charge, after the car has come to a position of rest, lifts the frame or guard-rail 12, by manually raising it, spring 23 assisting in the movement of the frame-work; when elevated, the parts assume, substantially, the position shown by broken lines in Fig, 2, the frame being just below the deck and near the eaves of the car, the movement of the parts at this time is upward and swinging, arms 20 and frame 12 remaining vertical and held by the pivotal mounting upon the pairs of U-shaped arms this movement is not obtrusive to disturb any passenger or other person, and the parts occupy no iioor space, as is obvious, it is intended that the elevation of the frame work may be accomplished easily while it must be lifted manually to cause its elevation, the resiliency of the spring on its crankmounting will cause the guard-member 12 and the arms connected therewith to be elevated, without any considerable manual effort. After the parts have been elevated as described, they will remain in a raised position from the resilient force of spring 23; after a passenger has left or entered the car, the guard-member is lowered; to effect a lowering of the guard-rail or member, the

employee pulls downward upon rail 1.5, or either of rails 13 or 14, or by partly turning crank-lever 24, secured to shaft 18.

By referring to Fig. 1, showing use. of the guard upon a summer or open car, it will be seen that frame-work 12 makes a closure of all of the entry or exit ways g the runningboard or side platform extends the entire, length of the ear, and devices now in use afford no protection tending to prevent a person from leaving any part of such ear, while the car is in motion, it is therefore eonsidered that the present invention provides a construction tending to prevent injuries, and is particularly adapted for use upon this class of street cars.

With reference to use of the guard upon summer cars, it will be noted that, when the guard-member is in a lowered position, a conductor or other person may stand upon or pass along the running-lmar(l, sincey supiorting-arms 20 and frame 12 are normally disposed adjacent the open side oil.' the ear a sufficient distance for this purpose. l provide crank 25 upon shaft 1S, and the coiled spring has one of its ends mounted thereon, its opposite end being` nounted under the roof of the car, the parts being so adjusted that the spring assists in raising frame l2, whenever required, and operates to sustain the parts in an elevated position, until frame 12 is manually lowered.

Figs. 3 and 4 show adaptation of use of the safety guard in connection with a closed or winter street car, the parts being the same, as just described with slight variations, these changes not being considered sullieient to constitute a departure from the invention, For use of the safety guard upon this class of street cars, two short frames 12 are used.` which are disposed in front of each end platform 2 and 3 of the car, shafts 18, liftingarms 19 and supporting-arms 20 being used in connection with the longitudinal frames 12. Said frames may be manually lifted by an employee in charge. of the car, in the same, manner as already described, to allow a passenger to enter or depart; while shaft la does not extend the entire length of the ear,

a longitudinal actuating-shaft 2() is mounted intcriorly of the car for the purpose of operating shafts 1S in unison, the ends of shaft 2G being provided with sprocket wheels 27. A sprocket wheel 2S is mounted upon each of exterior shafts 1S', and these wheels are eonnected by the chain 2Q; actuating-shaft 2d has a series of crank-levers 241 secured thereon, and a conductor when within the ear, may, by manual use of one of these levers, cause a common rotative movement of tho exterior shafts 1S', thereby elevating or lowering frames 12 as desired.

lt will be noted that the lifting-arms and supporting-arms are transversely disposed with .reference to the parallel shaft 1N and l guard-rail 12 upon which they are respectively mounted, ,whereby the swinging movement of the guard-rail is maintained substantially parallel with the car. I have specifically mentioned lifting-arins and supporting-arms for convenience of description only, and this particular designation is not important; the function of all of said `arms is toV support and to coperate in acontrol of theV 2.
