GEORG-E THEODORE SENN, OF OTTAWA, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO H. IVI. BEACH, F OTTAWACA1\TADA.

RAILWAY CATTLE-GUARD.

To all whom t may concern:

Be it known that I, GEORGE Trinonoxn SENN, a subject of the King of Great Britain, and resident. of 827 Somerset street, Ottawa, Canada, have invented certain new and useful Improvements in Railway Cattle- Guards, of which the following is a specification.

The invention relates to improvements in railway cattle guards, as described in the present specification, and illustrated in the accompanying drawings, that form part of the saine.

The invention consists essentially of the novel arrangement and construction of parts, whereby extensible gates located at `each side of the trackway are normally held to their folded position by weighted arms, and operatively connected to platforms arranged on the road-bed, which when depressed extend said gates across the trackway, where they meet and interlock.

The objects of the invention are .to devise an efficient guard, which will stand normally clear of the trackway, and will be automatically operated on the approach of animals along the road-bed, to extend across the tracks, and thereby effectually prevent their further progress.

A further object of the invention is to provide a guard of durable mechanical construction, which 'will in no m'anner be aV menace to the safe passage of trains.

In the drawings, Figure 1 is a side elevation view of the cattle guard as arranged on the road-bed of a trackway. Fig. 2 is a plan view of a section of road-bed, showing the arrangement of the cattle guard, the depressible platforms being partially broken away. Fig. 3 is a cross sectional view through the road-bed and cattle guard,

showing the gates in their folded position.`

Fig. 4 is a cross sectional view through the road-bed and cattle guard, showing the gates in their extended position. Fig. 5 is an enlarged sectional detail view, showing the additional safety pin for `the automatic release of the gates on the approach of a train.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 are the running rails of a railway supported as customary on the ties 2.

3 is a box casing located at each end of Specicaton of Letters Patent.

Serial No. 641,693.

one of the ties 2, and having the open front 4, and the opening 5 in the back.

6 are Oates formed of cross bars 7 pivotally secured intermediate of their length one to the other by the pins 8, and at the extremities thereof pivotally secured one to the other b v the pins in continuous toggle arrangement, whereby they may be extend ed as shown in Fig. 4, or may be folded one upon the other as shown in Fig. 3, such toggle arrangement'of cross bars being well known. The inner pair of the cross bars of each gate are pivotally secured to the box casing 3 by the pins 10 and 11 at the lower and upper extremities thereof respectively, the pin 10 extending through suitable journal orifices in the sides of the box casing adjacent to the back thereof, and the pin 11 extending into suitable vertical slots 12 in the sides of said box casing adjacent to ,the back thereof, said slots 12 allowing for the necessary movement of the pins 11 as the gates are extended or folded. The gates at the outer ends thereof have the end bars 13 and 14, said bars having the plates 15 secured thereto adjacent to the upper and lower ends thereof, the plates at the lower end of the bars being pivotally secured to the lower end of the outermost cross piece of the gates by the pins 16, and the plates 15 adjacent to the kupper end of said bars 13 and 14 provided with the vertical slots 17 through which the pins 18 extend from the upper end of the outermost cro-ss piece of the gates, the slot 17 allowing for the necessary vertical movement of the end of the cross piece as the gates are Aextended or folded.

19 are plates having the slots 2O therein, and secured to the sides of the box casings 3 in horizontal a'linement with the pin 10, the pivot pin 9a of the irst toggle section of the `gates extending into the slot 20 at each -side of the box casings 3, and thereby forming a .further support for the gates when -in their extended position, in addition to the pins 10 and 11.

21 are pairs of operating bars, having the longitudinal slots 22 extending therealong for the greater portion of their length, each pair of operating bars 21 vbeing .pivotally mounted on the inner endk thereofon lthe pins 23 extending between the sides of `the boxcasing 3 adjacent to the lower and outer ends thereof.

The pins 8a of the outermost toggle section of cross pieces extend through the slots 22, and slide in said slots as the gates are extended or folded, moving the said bars 21 when folded to a vertical position as shown in Fig. 3, and when extended to a diagonal position as shown in Fig. 4, the ends of the pair 0f bars 21 of one gate extending b-eyond the end pieces 13 and 24, and the top of the end piece 14 of the other gate is tapered to a point 14a, whereby the tapered end 14a will readily pass between the extended ends 24 of the koperating bars 21 of the opposite gate when the gates are extended and meet.

It must be understood that the operating bars 21 arranged as above described form a rigid reinforcement for the gates, thereby allowing a very light material to be used in the frames of the cross pieces 7.

25 are fulcrum levers extending through the openings 5 in the back of the box casings, said levers being pivotally secured to the back of said casings by the pins 26.

27 are connecting bars pivotally secured at the ends thereof to the operating bars 21 at 28, and the inner end of the fulcrum levers 25 at 29.

30 are brackets secured to the side of the tie ends at the ends of which the box casings are located, the tie being extended a short distance beyond said box casings. The brackets 30 extend upwardly, and have the weighted arms 31 pivotally secured at one end thereof to said brackets by the pins 32.

33 are weights adjustably arranged on the weighted arms 31.

34 are link bars pivotally connected at the lower end thereof to the weighted arms 31 by the pins 35, and at the upper end thereof pivotally secured to the outer end of the fulcrum levers 25 by the pins 36.

It will be readily understood that the weighted arms 31 exert a continual downward pull on the link rods 34, tilting the fulcrum levers 25, and drawing upwardly on theconnecting bars 27, and as the said connecting bars 27 are connected at 28 to the operating bars 21, said operating bars are normally held by the weights 33 to their raised position as shown in Fig. 3. By means of these operating bars the gates are moved to their folded position from the extended position as shown in Fig. 4, as the upward pull on the operating bars 21 tends to move the pivot pin 8L toward the lower end of the slot 21, and in so doing fold the gate, and in addition, acts as a constant upward support for the outer ends of the gates in their extended position where there would be a tendency for them to sag owing to Ytheir own weight.

37 are journal bearings bolted at the opposite side of the tie 2 to which the brackets 30 are secured.

38 is a hollow shaft journaled in the bearings 37, and Ahaving the solid shaft 39 extending therethrough and beyond each end` thereof.

40 are crank arms having t-he enlarged inner ends 41 secured to the hollow shaft 38 by the pins 42. One of said pins, as particularly shown in Fig. 5, extending through the hollow shaft 38 into an orifice 43 in the shaft 39, whereby the shaft 39 and the hollow shaft 38 are normally secured one to the other, and rotated as one in the bearing 37.

44 are rollers journaled on the shaft 44a extending through the ends of the crank arms 40.

45 are crank levers having the enlarged inner ends 46 thereof fixedly secured to the outer ends of the shaft 39. The outer end of each of said cranks 45 is pivotally connected to the link 47 with the weighted arms 31, whereby when the outer ends of the crank arms 40 are depressed, the outer ends of the cranks 45 are raised, and through the connection of the link 47 the weighted arms 31 are raised, and the gates moved to their extended posit-ion.

48 are platforms connected by the hinges 49 at one end thereof to the tie 2 by the side of which the brackets 30 are secured. The

platforms 48 are arranged between and at each side of the tracks 1, and extend over the rollers 44 of the crank arms 40, and are normally held in a slightly raised position above one of the ties 2 by the weighted arms 33.

50 are slanted approach platforms secured across the ties at each side of the depressible platforms 48, said approach platforms slanting upwardly at the ends next the depressible platforms, whereby anything which may drag from a passing train will in no manner interfere or catch either end of the depressible platforms, but will be guided clear over the top of the same.

When cattle or other animals attempt to walk along the road-bed of the railway, they must of necessity step upon one of the depressible platforms 48, and this added weight on the plat-form will counter-balance the weights 33 on the weighted arms 31, whereby said weighted arms will be raised through connections as hereinbefore described, the gates will be moved to their extended position across the track, effectually barring any further advance of the animals. Should it occur that an animal remains on the depressible platform, and a train is approaching, means is provided as shown in Fig. 5, for releasing the gates and returning the same to their folded position, in the event of the animal not moving from the platform. f

As hereinbefore mentioned, one of the pins 42 extends through the hollow shaft 48 into the orice 43 of the shaft 39, as particularly shown in Fig. 5, said pin being spring-held by the spring 5l to its inner position. j

52 is a bracket extending upwardly in the enlarged inner end of the crank arm 40 immediately next to the pin 42.

53 is a roller journaled on the pin 54 extending through the 4bracket 52.

55 is an elbowed cam lever pivotally secured to one of the rainning rails 1 considerably in advance of the cattle guard, by the pin 56, one section of said elbowed cam lever eing curved upwardly at 57 adjacent to the tread of the rail, and the other section of said elbowed cam lever being provided with a weight 58 which normally holds the curved end 57 a short distance below the tread of the rail.

59 is a length of cable connected at one end to the outer end of the weighted section ofthe elbowed cam lever 55, and extending over the pulley 53, and secured at the other end thereof to the pin 42.

Wlien an animal is upon one of the depressible. platforms 48, and the crank arms 40 are depressed, t-he cable 59 is pulled a sufficient extent to raise the curved section 57 of the cam lever 55 a slight distance above the tread of the rail and immediately at one side thereof, and as a train approaches, the curved section 57 of the cam lever 55 will be depressed by the flange of the wheel, and the pin 42 withdrawn from the orifice 43 of the shaft 39, and thereby allow said shaft 39 to rotate with the crank 45 and weighted arm 31, and the several connections all move the gates to their folded position. As soon as the animal has moved oif the depressible platforms, the same are returned to their normal position by the spring 60 connected at one end thereof to a bracket extending from one of the ties 2, and at the other end thereof to the bracket 6l extending from the shaft 44a. As soon as the depressible platforms with the crank ends 40 are returned to their normal position, the spring-held pin 42 is again brought into register with the orifice 43, locking the hollow shaft 38 and the shaft 39 together.

It will be understood that many changes may be made in the detail construction of the several parts of my invention withoutl departing from the spirit of the same, and l do not wish to confine myself to t-he mechanism or particular arrangement of levers as shown in the accompanying drawings. In fact, the toggle sections of the gates may be entirely done away with, leaving the operating bars 2l to extend across the trackway, and pickets or other cross pieces l'ixedly secured to these operating bars to form a barrier of limited efficiency.

That I claim as my invention is:

l. In a railway cattle guard, the combination with a cross tie extending across the road-bed, a box casing, an extensible gate comprising a series of cross .pieces pivotally secured one to the other in toggle form, means for pivotally securing the inner set of said toggles in said box fra-me, a weighted arm operatively connected to said gate and normally moving the several pieces thereof to their folded position, a depressible platform hingedly secured at one end thereof to said tie and means for operatively connecting said depressible platform to said weighted arm.
