SAFETY ATTACHMENT FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 534,218, dated February 12, 1895.

Application filed March 2, 1894. Serial No. 502,069. (No model.)

To 60% whom it may concern/.-

Be it known that I, ALBERT E. HUGHES, a citizen of theUnited States, residing at Darien', Fairfield county, Stateof Connecticut, have invented certain new and useful Improvements in Safety Attachments for Street-Cars, of which the following is such a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and use the same, reference-being had to the accompanying drawings, forming part of this specification.

My invention relates to devices which are designed to be attached to the forward ends of cable or electric cars for the purpose of preventing a person from being run down by the car or brought into contact with the wheels of the moving car. In many of the known safety devices used for this purpose, the mechanism employed necessarily occupies such a great space lengthwise of the car as to render them practically useless and in a number of the devices used prior to my invention there exists a serious drawback in the fact that no adequate provision is made whereby the mechanism necessarily makes such close and firm contact with the surface of the roadway when brought into service as to render impossible for a person to pass under the car. In other words, in using them they are quite apt to fail to catch a person and hold him out of all danger of being injured by the car or its wheels.

The principal objects of my invention are to overcomethe above-stated objections and to these ends my invention consists in the various novel and peculiar features and arrangements and combinations thereof, as

hereinafter fully described and then pointed g out in the claims.

In the accompanying drawings wherein I have illustrated a type of my invention together with modifications of features thereof,

Figure 1 is a perspective view of the forward end of an ordinary street car that is provided with my improved safety mechanismthe propelling power of the car being, for example, that of an ordinary cable traveling in a conduit extending along the road, the slot of the conduit being shown as extending midway of the rails. In this view, the sliding: screen into which a person may dropis shown in retracted position ready to be shot forwardly in the event of the trip-device striking a person. Fig. 2 is an enlarged view in section taken on a plane parallel with the slidingscreen, with the flexible guard omitted and the upper portion of the frame of the slidingscreen shown in part. Fig. 3isa view of another section taken on a plane between the sliding-screen and the stationary screen or fender in front of it. Fig. 4 is a horizontal sectional view taken on a plane indicated by line 44t, Fig. 3. Fig. 5 is a view in section taken on a central vertical plane and shows the relative positions of the parts when the sliding-screen has been projected forwardly. Fig. 6 is a view in section on planes indicated by lines 6-6, Fig. 2 the sliding-screen being held in retracted position ready to be shot forward upon the action of the trip-device. Fig. 7 is a view in horizontal section on a plane indicated by line 77, Fig. 5. Fig. 8 is a front View of oneform of the yielding-guard. Fig. 9 is a side view of the same, and Fig. 10 is a View thereof in section on a central vertical plane indicated by line 10-10, Fig. 8. Fig. 11 is a front view of another form of the yielding-guard. Fig. 12 is a side view of the same. Fig. 13 is a view of the same in section taken on a plane indicated by line 13-13, Fig. 11; and Fig. 14 is a detailed view showing the arrangement of one of the springs that is coiled about the rock-shaft upon which the guard is mounted, as will be hereinafter described. Fig.v 15 is a View, partly in section, on a central longitudinal plane, of the mechanism for putting on the brake and shutting off the propelling power, as will be hereinafter fully described.

Referring to the drawings, in which like numbers of reference designate like parts throughout, 10 is a platform of an ordinary street car propelled by other power than horses, and provided with the usual dashboard 11, to each end of which is affixed a vertically-arranged plate 12 which projects forwardly and is suitably shaped to receive and house the several parts mounted therein. In

front of the dash-board and between the sideplates I mount a stationary-screen or fender 13 which is preferably curved about a horizontal axis extending at'right angles to the length of the car and when so curved its curvature should have preferably a slightly shorter radius than the sliding-screen 14:, which is arranged to lie normally back of said tender and to shoot from under its lower edge when 5 called into use. This stationary-screen may be formed of any suitable material and if preferred it may be made with a frame that is fastened to the side-plates, though in the con struction illustrated I have shown it as con- IO sisting merely of a piece of netting formed of wire or cotton and secured tightly to the front edges of the side-plates which are shaped in arcs of the desired curvature.

The sliding-screen 14 is arranged interme- 15 diate the dash board and the stationaryscreen with which it telescopes and it preferably comprises a rectangular frame having curved side bars 15, 15, and end bars 45, 46,

within which is secured a netting 16, that is preferably flexible. The sides of the frame are provided with guide-projections or lugs 17 (see Fig. 2) which travel in arc-shaped guide-slots 18 formed in the side-plates 12, upon which are also mounted guide-rollers 125. Thissliding-screen is formed of alength sufficient to aiford the necessary area or surface for receiving a person when the screen is projected forwardly as shown in Fig. 5. The curvature of the screen may be made on any desired are though obviously it should not be formed on a curvature having a very short radius. r

The upper part of the sliding-screen is connected by means of links 19, 19, with the free 5 ends of a pair of swinging- arms 20, 20, re-

spectively, which are mounted at their inner ends upon a pivot 21. (See Fig. 7.) The pivot21,is mounted in fixed position and the arms turning thereon are designed to have a 4.0 longrange of movement at their free ends in order to properly throw or project the slidingscreen the necessary distance ahead of the car. Each of the arms 20, is provided near its pivoted end with a fixed-stud 22 which 5 travels in a horizontal slot 23 that is formed in avertically-moving slide 2 L which is acted upon in a downward direction by a spring 25, interposed between a fixture 26 on the dashboard and a collar 27 that is made fast on the slide. The slide is provided near its lower end with a guide-slot 28 which travels overa fixed-pin 29 set on a cross-beam 127 and normally the slide is held at its upward limitof movement by means of a tripping-device 30 that is designed to extend across the width of the ear and in advance of the sliding-screen, as well as the stationary-screen or fender and the side-pieoes12. This trip-device is of novel construction and consists in a horizontallysliding framework made up of side-pieces 31, 31 (see Figs. 3 and 4), with cross-bars 32, 32, the inner one of which carries at its center of length a wheel or roller 33 which may be adjusted beneath the foot of the slide so as teenstain it in its uppermost position. The inner ends of theside- bars 31, 31, rest upon a crosspiece 3% which is secured between the side plates 12, 12, while the side-bars 31 near their outer ends travel on anti-friction rollers 35 in order to make the device move with but little friction when it collides with a person. When the wheel 33 of the trip-device is adjusted under the foot of the slide, the sliding-screen 14, is held retracted by means of the arms 20 and their links 19, but as a further precaution for holding this screen retracted I lock the lower end thereof with a projection 36 on the tripping-device, as shown in Figs. l, 5, and 6- the projection 36 taking into a notch 37 conveniently located on the under side of the lower bar of the sliding-screen.

In Figs. 8, 9 and 10, the tripping-device is slightly modified in form in that the side-bars thereof are straight and the cross-bars arranged in the same plane with each other and with the axle of the wheel 33. 'As the frame is considerably longer in this form, I provide a stop for preventing its dropping down too low after it has been pushed inwardly by contact with a person. This stop consists in an arm 190 depending from each of the sideplates 12 and each provided with an inwardly projecting-stud 191 upon which the frame rests when it drops downwardly after being forced in. By virtue of having the springactuated slide held against the action of its spring by resting on the periphery or rim of a wheel so as to utilize the dead-center thereof, I am enabled to provide a very sensitive tripdevice that requires but a slight impact with a person in order to at onceproject the sliding-screen into proper position to receive the person thereon.

The lower end of the sliding-screen, which is apt to strike a person when projected, is provided along its lower edge with a springcushion comprising a rod 38 having guidepins 39, each of which is surrounded by a spring 40, interposed between the rod 38 and the bar 45 at the lower end of the slidingscreen. (See Figs. 3 and 5.) These springs normally keep the rod 38 at its outward limit of movement so that when the screen is pro jectcd and such rod comes forcibly in contact with a person it will readily yield and thereby avoid injuring such person as would be the case in the absence of the cushion.

In cases where the car isprovided at each end with one of myimproved attachments the one at the rear end is locked in closed position with the sliding-screen held retracted and against accidental operation by the action of the trip-device, by means of a locking pin4l which may be placed through a hole 42 formed in the slide 24rso as to take against the upper face of a fixed bracket $23 that is securedto the dash-board of the platform, as will be fully understood from Figs. 5 and 6. This pin maybe readily manipulated through the hand-hole 44 formed in the dash-board.

The netting 16 of the sliding screen 14; is so mounted therein that it may readily sag, as shown in Fig. 5, whenever aperson is thrown upon it. This is designed to firmly lodge or ICC nest therein a personwhen precipitated upon the net and is an important feature of my invention. This sagging should be great enough to provide a hollow or pit-like place that is amply sufficient to receive a person, its limit in fact being determined only by the elevation it must have in order to clear the ground and not to drag thereon when a person is lying in the net. There are many ways in which this peculiar feature may be provided though I have shown but one way which is as follows: The frame across which the net is stretched is composed of the side-bars 15, 15, a lower end-bar 45 and an upper-end bar 46, all of which are secured together. In the upper end of the frame is mounted a sliding-bar 47, the ends of which travel in guides 48, 48, in the side-bars 15. This sliding-bar 47 is attached to the end 46 of the frame by a number of springs 49 which are to be made of sufficient length to produce the necessary sagging of the not when a person falls upon the latter and the springs are stretched or strained. The net itself has its lower end made fast to the bar 45 at the lower end of the frame and its upper end is likewise made fast to the sliding-bar 47, so that when a person falls upon the net the bar 47 will slide downwardly in its guides, at the same time being held by its series of attached springs 49, which act to atonce draw the bar back and hold the net taut upon the removal of the person from the net.

At each side of the attachment is arranged a folding net 50 that is secured at suitable points 51, and 52 to the front edge of the sideplate 12 and is attached by its lower end to a point 53 on the sliding screen 14, so that when the latter is in retracted position the side not is compactly folded up out of the way. When the sliding-screen is projected forwardly each side-net is unfolded as shown in Fig. 5 and affords ample means for preventing a person that may be thrown into the sliding-screenfrom fallingoutsidewise. Thesefoldingsidenets 50 may also be provided with a spring 54 at their upper ends to hold them taut.

The lower and forward end of the slidingscreen is preferably arranged a suitable distance above the ground in order that it may strike a person at or a little below the knees and serve to knock him off his feet. This action precipitates the victim into the not which sags to such an extent that it securely pockets him and thus he is held out of danger of being in any way injured by the car or its wheels even though the car continues to move. It will be noted that the lower limit of the sweep of the sliding-netis ata sufficiently high point of elevation above the ground to permit it to clearaperson that may belying on the ground. Should the person after being struck by the trip-device fail to be precipitated into the net or held therein after being precipitated into it, the lower end of the net will clear him should he then fall upon the ground, and the continued movement of the car will then bring the yielding-guard into play and the latter will catch up the person and hold him in safety.

To the rear of the sliding-screen I arrangea yielding-guard which extends entirely across the track and just clears the ground for the purpose of catching and holding a person who may be lying upon the ground, in which event the sliding-screen will clear the victim without injury and allow the guard to-pick him up. This guard which may be termed an emergency-guard should the sliding-screen fail to catch and hold the victim, is placed forwardly of the car-wheels and preferably in advance of the dash-board as shown in the drawings, so that in the event of the slidingscreen failing to catch the person in danger of being run down by the car, the guard may serve to prevent the person from coming in contact with the wheels. I have shown in the drawings three forms of this emergency- .guard, the form illustrated in Figs. 1 and 5 consisting in a broom-like device having a shaft or head 55 mounted horizontally across the side-plates 12 in brackets 56, 56, which are secured upon the inner sides of the said plates. From the under side of the shaft 55 project yielding-fingers or blades 57 which are arranged in bunches placed close together.

The fingers or blades that lie forwardly of the vertical plane (containing the axis of the shaft on which they are mounted) projectdownwardly and in a forward position with their lower ends a slight distance above the ground while the blades which are disposed to the rear of such vertical plane are inclined downwardly toward the rear. If now this yielding-guard should come in contact with a person lying across the track, the blades or fingers which project forwardly would at once be forced into contact with the ground at their ends, after which the continued pressure thereon will cause them to bend or bow and thus carry the person along in front of them until the car may be stopped. The fin gers or blades that lie to the back of the guard prevent the forward blades from bending or bowing to such a degree as to allow the person to be forced through and under the forward blades-the pressure exerted between the guard and the person beingtransmitted from one row of the blades to the other as they are crowded against each other and finally transmitted to a rigid back-piece 58 depending from the platform and extending across the back row, of the blades.

The shaft 55 of the guard is loosely mounted v in the brackets 56, 56, so that it may be raised in order to lift the guard a considerable dis tance above the ground when it is not desired to have it in position for use. raised by means of a foot-lever 59 which is pivoted to a fixed-point 60 and connected by means of a link 61 to the upper-side of the shaft 55. Theinner end of this foot-lever extends through an opening in the dash-board and it is provided with asnap or spring-latch 63 for looking with it when its inner end is de- The guard is.

pressed. (See Fig. land 5.) By forcing down the inner end of the foot-lever the guard will be lifted up-the shaft, the link and the lever assuming the dotted line position shown in Fig. 5, in which position the parts are locked automatically by the spring-latch, and they may be so retained until the snap or latch is released by hand.

In the modification of the yielding-guard shown in Figs. 8, 9 and 10, it substantially comprises a swinging arm (is depending from each side-plate l2, and connected at their lower ends by a spring-shoe from which extends rearwardly a flexible net 66 that is attached to the vertically-sliding rod 67 moving in guide-slots 68 formed by the brackets 69. This sliding-rod 67 is attached to a fixed bar 70, arranged above it in the bracket, by a number of springs 81, 81, which normally hold the sliding-bar up. The design and the operation of this bagging-net is the same as that described with reference to the net 16 of the telescoping or sliding-screen. Each of the arms 64 is formed with a vertical-slot 71 that travels overapin 72 fixed upon a bracket 73 secured to the outside of the side-plates 12. The upper end of each arm is pivoted at 74 to the head of another arm 75 which carries a pin 76 working in an arc-shaped slot 77 formed in the bracket 73. The curved slots and pins serve to determine both the forward and backward limit of movement of the tripdcvice .as well as the guard The arms 7 5 are slightly bent upon themselves so as to throw the lower and front ends ahead of the frame carrying the net and they are connected at their upper ends by a rod 145 and at their lower ends by a bar 78 which forms a tripbar extending in front of the spring-shoe 65 of the yielding-guard. A spring 79 is connected between a suitable fixed point and the pin 74:, which unites each side-arm 64 of the guard with the side-pieces of the tripping-device, and the parts are so adjusted that in normal position, wherein the trip-bar 78 is heldin advance of springshoe 65, the pin 76 and the slot 77 hold the parts locked as shown in Fig. 9. hen now the trip-bar 78 strikes against anything and is thrown inwardly, the pin 76 is carried backward through the slot 77 until the dead-center, on which the spring 79 is normally drawing, is passed, whereupon the spring snaps the tripping-device in a backward direction and carries it into the position shown in Fig. 10. This same movement also forces downwardly the springguard and carries the spring-shoe 65 into contact with the ground with such force as to cause the shoe to press tightly against the ground under spring tension-the shoe itself being bent or compressed from the form shown in Fig. 9 to that represented in Fig. 10. The upper part 80 of the spring-shoe is .inclined downwardly and being made of thin spring metal it will scrape along the surface of the ground, as the car advances, and acting like a shovel it will readily scoop up a person encountered by it so that the person will roll or move backwardly on to the net which will sag sufficiently to receive and hold the victim out. of all danger of being injured by the wheels. The sagging of the net extending backwardly from the spring-shoe is further insured by the positive action thereon of the tripping-bar 78 which after collision with a person is forced backwardly until the dead-center upon which the spring 79 normally exerts its forceis overcome whereupon the spring then throws the tripping-device to its rearmost position as shown in Fig. 10. In moving into this latter position the trip-bar '78 passes along the upper surface of the net and in doing so continues to depress it and draw out the springs 81, as shown in Fig. 10.

In the form of the yielding-guard shown in Figs. 11 to l-t inclusive, the guard comprises the two side -arms 6st, 64, which are fixed upon a rockshaft 82 mounted across the lower ends of the side- plates 12, 12. The arms are curved slightly forward and connected across at their lower ends by a rod 83. A net 66 is secured by its lower end along the rod 88 while its upper end is attached to a sliding-bar 67 moving in guides 68 located upon the upper portions of the arms 64:. A set of springs 81, 81, are connected between the sliding-bar 67 and the rock-shaft 82 and normally they are free to act so as to hold the bar 67 to its upperlimit of movement and thereby keep the net taut. These arms are each provided with a laterally-projecting guiderpin 84:, which moves in the curved-slot 85 formed in a bracket 86 which depends from the adjacent side-plates 12. This pin and slot affords a sliding bearing for the guard intermediate its upper and lower ends and steadies it in its swinging movements as wellas serving to limit the length of vibration of the guard on its center of motion. The guard is normally held at its outward limit of movement and well above the ground by means of springs 87 which are coiled about the rock-shaft 82. With this form of guard it will be readily understood that when in its normal position, (shown in Fig. 12) it strikes against-a fallen person it will at once be forced backwardly into the position shown in Fig. 13 in which movementthe springs 87 are put under tension. As the car continues to move the person is rolled onto the net which sags by virtue of its connected springs, so as to form a pit into whichthe person is received and nested safely against dislodgrnent by the further movement of the car. The lower edge of this guard is provided with springfingers 140, which are secured upon the rod 88 (see Figs. 13 and 15) and theyare designed by their spring-movement when forced into contact with the surface of the roadway, to prevent the garments of the victim from getting wedged in between the guard and the ground which occurrence would tend to keep the person on the ground and prevent the forward movement of the car from rolling or catching the garment of a victim between itself and the ground and thereby accidentally binding him to the ground in a dangerous manner. 1

If preferred a tripping-device may be used in conjunction with the form of swingingguard just described in order to fullyinsure the movement of the guard toward the ground before it encounters the fallen person and for such purpose a tripping-device similar to that shown in Figs. 8, 9 and 10 may be adopted.

From the foregoing description the operation of the sliding and shooting-net for throwing and catching a person as Well as the operations of theyielding-guards, will'be readily understood without further explanation.

My invention is not limited to the constructions herewith illustrated and described, as the principles upon which the different features work may be embodied in other forms without making a material departure from the spirit of my invention.

While I have shown the sliding-screen and the yielding-guard, as used in conjunction with each other, they need not necessarily be so used, for it is obvious that either device may be used without the other as is contemplated by the claims herein. However, it will doubtless be found safer to use the yielding-guard in conjunction With the slidingscreen in order to catch the victim when lying upon the ground and when the slidingscreen is not thrown into operation, because of the trip-device clearing the fallen person, or to use it as an emergency safety device, in the event of the screen failing to catch and hold the victim when the sliding'screen is operated.

Another feature of my invention is the pro- Vision of means whereby the brakes of the car may be automatically put on or thrown into action, by the more impact with a person of a suitable part of the safety attachment, whether the trip-device of the sliding-screen, or the guard mechanism.

Still another feature of my invention is the provision of means for automatically cutting oif the propelling power of the car byimpact of a suitable part of the apparatus with the person. These automatic devices may be arranged to act together in order to simultaneously shut 06 the power and put on the brakes, or they may be used independently of each other, or one of them may be used without the presence of the other. It is manifestly preferable to have that part of the apparatus which extends farthest in advance of the car, connected with and controlling the automatic braking-device or the power-cutting-off device, or both, in order to stop the car as quickly as possible when such part touches a person that is in danger of being run down by the car. fore, contemplates the automatic operation of the brakes, or the automatic cutting-off'of the propelling power, or both, by means of a tripdevice projecting well ahead of the car.

There are many ways which will readily suggest themselves to those skilled in the art of carrying out this broad idea and while I have shown but one way of doing so, I wish to be understood as not limiting myself to such particular way.

The construction referred to is shown in Fig. '15 wherein indicates the body of an ordinary street car provided with platform 10 having dash-board 11 in front of which is mounted the telescoping-screen 14 with its trip-device 30, as shown in detail in Figs. 1 to .7 inclusive. Beneath the platform is arranged the form of swinging-guard shown in Figs. 11 to 14 inclusive, both the sliding-screen and the yieldinguard being independently connected with the operating-valve 91 of an ordinary form of air-brake 92, which when thrown into operation forces the brake-shoe 93, against the car-wheels 94 through means of the brake-rod 95 and a pivoted-lever 96. The compression of the air for the brake apparatus is effectedthrough means of the piston-rod 97 which is connected witn therod 98 driven by theeccentric '99 on the axle of the car-wheel. The rotary valve-rod 100 of the controllingvalve 91 carries at its upper end a handle 101 by which the rod may be turned -by the motorman in order to operate the brake by hand in the well known way, when it maybe so desired. This valve rod 100 carries a depending arm 102 which is engaged by an ondwise sliding-rod 103 provided with a spring 104 which tends normally to thrust the rod forwardly in such a way as to move the depending-arm 102 and thus turn the valve-rod 100 through part of a revolution and thereby actuate the controlling-valve of the air-brake. This sliding rod 103 is normally held with its spring compressed, when the sliding-screen 14 is retracted, by means of a stop 105 located upon the vertically-moving slide 24, so that in the event of the tripping-device 30 striking a person the stop will move away from the rod 103 and thus cause the air-brakes to be put on.

The swinging-guard 64 is also arranged to control the operating-valve 91, through means of a finger or push-piece 106 secured fast upon the rock-shaft.82 and engaging with its free end a projection 107 extending outwardly from the depending-arm 102 of the Valve rod. When now the yielding-guard strikes against a person lying across the track the shaft 82 will be rocked and thus move forwardly the finger 106 against the projection The invention, there- 107, which will thereby be moved sufficiently to turn the valve-rod and operate the valve so as to put on the air-brake.

Atasuitable pointin the electric-circuit 108, which leads from the electric motor (which is not shown) into the box 109 containing the usual electric switch and resistance mechanism, I locate an ordinary electric switch 110 having a movable switch-arm 111 pivoted at 112 and connected by one cord 113 to the finger 106 of the yielding-guard, and connected by another cord 114 to the sliding-rod 103- the latter cord passing arounda pulley 115. If now the tripping-device 3O strikes against a person the slide 2t will be forced downwardly so as to carry the stop 105 out of the way of the sliding-rod 103 which will then shoot forwardly and drawing upon the cord llwill raise the switch-arm 111 so as tobreak the motor circuit and cause the motor to be brought to rest, at the same time serving to put on the brake as above described. The yielding-guard also serves, when it collides with a person, to open the switch through means of the finger 106 and connected-cord 113 and thus cause the motor to stop, at the same time putting on the air-brake as previously described. By virtue of controlling the propelling power or motorand the brake 'bythe movement of the tripping-device which projects ahead of all other mechanism and likewise controlling the same devices by the yielding-guard, it will be seen that as soon as either the tripping-device or the yieldingguard collides with the victim, the brake is automatically put on and the power for propellingthe car is simultaneously disconnected or rendered inoperative so that it will not continueto drive the car. It will thus be seen that I provide a most effective way of preventing a person from being run down or injured by a cable or trolley car.

\Vhen the apparatus shown in Fig. 15, is applied to a cable car, instead of an electric car, the connections are made between the grip-releasing device and the yielding-guard and trip-device, so that upon the operation of either of the latter, the grip may be caused to let go of the propelling cable in order to stop the propulsion of the car.

In the present specification no claim is made to the specific form of yielding guard shown in Figs. 1 and 5, but I wish to be understood as not abandoning such invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of a car, a stationary fender mounted across the forward end of the car, in front of the dashboard a sliding-screen normally disposed intermediate the fender and dashboard and adapted to be projected or thrust in advance of said fender, means for sliding or projecting the screen and a tripdevice normally extending in advance of said fender and screen for locking and releasing said projecting means.

2. The combination of a car, a stationary fender curved on an are about a horizontal axis and arranged across the front end of the car, a similarlycurved sliding-screen mounted in guides to the rear of said fender and describing an arc in its sliding movements about a horizontal axis, said screen normally held retracted back of said fender and adapted to be projectedor thrust forwardly of the fender from beneath the same, a trip'device for said screen and means for forcibly projecting it when released.

3.
