MARCUS I1. KEIZUR, OF BAKER CITY, OREGON.

AUTOMATIC LIFE-SHEET FENDER.

To all whom it may concern:

Be it known that I, Martens L. KEIZUR, a citizen of the United States, and a resident of Baker City, Baker county, Oregon, have invented a new and useful Improvement in Automatic Life-Sheet Fenders, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention relates to fenders of the pick-up type, that is to say, of the class in which the person run down is picked up and carried by the fender until the car can be brought to a standstill; and my invention has for its object to provide a fender of this type so arranged, and operating in such wise that the pickup devices cannot, under any usual circumstances, skid, or pass over the person run down, but, on the contrary, may be depended upon, under all usual circumstances, to properly perform their work; and, furthermore, my invention has for its purpose to provide pick-up means which will minimize the bruising of the person picked up from the track.

To this end my invention, in its general aspect, resides in the combination with the car and a wheel-guard, arranged pendent in front of the wheel-truck, of a life'sheet fastened at one end under the car, in advance of the wheel'guard, the free end of which lifesheet is preferably weighted and rolled, so as to unroll from the bottom of the sheet; means normally supporting said life-sheet in its rolled state; a movable member pendent in advance of the wheel-guard, and means operated thereby arranged to release said rolled life-sheet and drop the same to the ground.

The life-sheet is made of any suitable 1naterial, and is so arranged that when released it will drop in front of the person lying across the car-track, in front of the wheelguard, and will work under him while unrolling on the ground during the continuous forward movement of the car, and carry him along with the car until the latter can be brought to a standstill. In other words, when the life-sheet has been dropped, and has worked under the person lying across the car-track, it will operate as a litter, carrying said person until the car can be stopped. V

In order that the life-sheet may perform its described work, it is necessary that the same be rolled as illustrated in the drawing,

for if rolled in reverse direction it will not work.

The arrangement of the contrivances by which my object is obtained are illustrated in the drawings, in which:

Figure 1 is a side elevation of the front end of a car provided with my improved fender; Fig. 2 is a perspective detail of the construction shown in Fig. 1; Fig. 3 is a perspective detail of my fender, showing the life-sheet as having been dropped and in the act of unrolling under, and carrying along, the person run down, who is swept forward during such instance by the wheelguard; Fig. t is a longitudinal, sectional detail, illustrating the arrangement of a box extending cross-wise and supported under the car-sills, and in which box the life-sheet is normally carried in its rolled state; this figure also illustrates the withdrawing of the latch by which the drop-bottom of the box is normally supported; Fig. 5 is a cross-sectional detail, on a larger scale than Fig. 4, showing more particularly the construction of said box in which the life-sheet is normally carried as mentioned, and further showing the provision of spring arms for the purpose of firmly holding the lifesheet in place and forcibly ejecting the same from its containing box the instant the dropbottom of the box is released; Fig. 6 is a detail of construction of a type of wheelguard; Fig. 7 is a detail illustrating the provision of a cover attachment for the lifesheet, so arranged as to be wrapped around the exterior of the latter when rolled up, for the purpose of protecting the. life-sheet from the weather and dust, when it is not practical to normally carry the life-sheet in an inclosing box; Fig. 8 is a partial side elevation of the front end of the car, illustrating my invention as applied to a car of the short-end type and provided with a projecting fender, and my life-sheet is shown as attached to and carried under such projecting fender instead of being attached and carried under the body of the car, as shown in the illustration of Fig. 1; Fig. 9 is a larger-scale perspective detail of the arrangement of the parts shown in the modified example of Fig. 8; the ends of the lifesheet in this figure are shown flush with its supports, but in practice they would project beyond; Fig. 10 is a. diagrammatic detail of construction, more fully described in the body of the specification; and Fig. 11 is a detail of the rolled-up end of the lifesheet showing the same as made with a hem or loop at the end, and a metal cable inserted therein as a weight to hold said end on the ground, when unrolled.

Referring in the first instance to the type of my invention illustrated in Figs. 1, 2 and 3: the same comprises a wheel-guard a, of any convenient type, adapted to sweep the track-surface in advance of the front wheel-truck and thus prevent anyone from getting under the wheels. A simple and convenient way of constructing the wheel-guard is shown in Figs. 2, 3 and 6. It consists of a series of rods 0;, arranged pendent by being bent double, as shown in elevation in Fig. 6, and the upper ends of the two members Z2, 6 being bent around a transverse shaft 0, supported from the car-sills f, f by hangers 0, 0 The hangers 0, 0 are arranged to allow the shaft 0 some vertical play against the spring arms 9, g, fastened to the car-sills and normally holding the shaft 0 down, so as to normally keep thebottom ends of the arms of the wheel-guard, a, close to the ground. The ends 6, b are extended through a perforated angle-iron d, suspended by stirrups e fastened to the hangers 0, 0

In order to hold the angle-iron d more securely in place, I connect the same with the shaft 0 by straps it, one near each end of said shaft; such straps being bent around the shaft 0, and the outer ends of said straps being bolted to the angleiron d.

In front of the wheel-guard there are affixed, to the car-sills f, f, hangers z, z", and from said hangers is pivotally suspended a movable member or trip-bar j, adapted to be swung back by contact with the person lying across the track and having connections arranged to release the life-sheet when the trip-bar is swung back.

The life-sheet la is made of canvas, or any material having a surface capable of clinging to the clothing of the person run down, and simultaneously unrolling on the ground under the person. One end of said life-sheet ic'is attached by chains is, or otherwise as convenient, to a bar Z, and the life-sheet is rolled in the form of a roll and normally carried in a'box we, having a drop-bottom m, which is normally retained in place by a latch-bar n, connected at one end to the trip bar j. The box at is fastened to the hangers '2', 2'.

In order to insure that the life-sheet will be instantly thrown upon the ground, the moment the drop-door m is released by the pulling from under thereof the latch-bar n, I provide spring-arms 0, 0, 0 The front and rear walls of the box m are provided with slots m as illustrated in Figs. 2 and 5, for the spring-arms 0 to project through, and act as mentioned. Said spring arms also hold the rolled life-sheet against becoming unrolled by the vibration of the car in travel.

The operation of my fender is as follows: Supposing that the person having fallen across the track has passed under any projecting fender with which the car may be equipped, he will, in the next instant, come in contact with the trip-bar j, swinging the latter back and thus drawing the latch-bar from under the drop-door m of the box m and releasing the life-sheet 7a, which immediately drops on the ground in front of the person on the track. The life-sheet 7c is rolled in such manner as to unroll, as illustrated by 70 in Fig. 3. The instant after the movable, pendent member or trip-bar has been swung back, as illustrated in dotted outline in Fig. l, the person lying across the track will come in contact with and be swept forward by the wheel-guard. The same instant the dropped and unrolling end of the life-sheet will have reached the person, and as the car continues to move forward, the roll will pass under the person, and thereupon the life-sheet will operate as a litter, carrying the person forward with the car. I find it advisable to make the life-sheet of such length as to extend some distance back under the wheel-guard, as shown in dotted outline in Fig. 3.

The described operation of the life-sheet is illustrated in Fig. 3.

It is apparent that while the person carried along on the life-sheet may be bruised to some extent by the roughness of the surface over which he is being dragged, nevertheless he is greatly protected by the lifesheet, 70, lying under him, and particularly so by reason of the front end of the life sheet rising above the ground and causing the same to have a sort of skidding motion over the ground.

It should be noted'that the body makes no forward progress whatever on the life-sheet after the instant of contact, as would be the case if the body were swept onto an outspread sheet; on the contrary, through the impinging weight of the body on the unwinding sheet and the consequent forcible adhesion of the surfaces of the sheet with the pavement, the roll can do naught but pass under the body, presuming, of course, that the body is beingswept forward on the pavement by the wheel-guard. The unrolling of the rolled end of the life-sheet also act-s to cause the latter to work itself under, as it were, and to lift up on the roll any projected arm or leg of the person picked up. Even if the rolled end of the life-sheet should fall partially on the body, it will roll off, and act as described. For since the lifesheet, in the act of unrolling on the pavement, in the direction of the wheel-guard, in reality travels forward, it will consequently have a tendency to roll off the body and then go under, as the weight of the body tightens on the unrolling sheet.

In Fig. 7 I have shown the life-sheet as provided with an exterior wrapping sheet 9, made of such material and so arranged that when the life-sheet is rolled up, the wrapping sheet will incase the former and protect it from dirt and weather. The rolledup end of the life-sheet is provided with a hem or fold or loop in which is inserted a piece of cable or chain 70* (see Fig. 11) so as to give said rolled end some weight, facili tating the dropping thereof on the ground, and also holding the same end on the ground, notwithstanding strong head winds. I prefer to use a flexible, instead of a rigid weight for the rolled end of the life-sheet. The attachment of the front end of the lifesheet by chains 7: allows any head winds to get over the top of the sheet, and the weight of the chains 70 also contributes to the dropping and holding of the life-sheet on the ground.

The arrangement of my fender contrivances, as shown in Figs. 7 to 10 inclusive, is substantially the same as already described, except that in this instance by reason of the wheel-trucks being so near the front end of the car, it is necessary to so modify my fender as to suit such conditions imposed upon it.

The wheel-guard, a, is of the same construction as has been described.

From the bottom of the car is suspended a hanger r, in which is supported the swinging trip-bar s. Said trip-bar is connected by a chain 23, having branches 6', with the sliding sleeves to on the projecting framemembers a. The last described arrangement is diagrammatically illustrated in Fig. 10. A pendent piece of chain 25 prevents sagging of chain lengths t, t.

The frame-members a have each a boxclamp 'v, and a clip 4) to which the suspending chain to of the projecting fender-frame is fastened; and under each of the boxclamps o is provided a short box .2 for the ends of the life-sheet 7a to normally lie in; said box a being provided with a drop-bottom 2, the extremity of which is inserted in the perforation of a pendent keeper 2, fastened under the sleeve to, and the latter and therewith said keeper are held in their normal places by a spring An angle-bar 4 prevents the rolled life-sheet 70 from bearing against the keeper 2, which would have a tendency to prematurely unlatch the dropbottom a. The life-sheet 7c is connected by chains 5 (the equivalents of chains is) to the fender frame-members u; and since the boxes a merely inclose the two ends of the life-sheet roll 71:, in this instance the outer protectin sheet 7 comes into good stead, as a protection against weather and dust.
