LGCKING DEVICE FOR SPOU'IS.

Application filed April 27, 1927. Serial No. 186,993.

The present invention relates to a device for lockingthe delivery spout of a railroad water supply tank in a lowered position so that the spout cannot swing upwardly.

Due to the pressure of the water as the same passes from the tank through the de-' livery spout, the spout has a tendency to raise upwardly, and as a result, considerable difiiculty is experienced by a fireman on an engine in properly holding the spout while taking water. It is therefore an important object of the present invention to provide a simple and eficient means whereby the spout maybe locked in a lowered operative position, thus obviating the necessity of the fireman having to hold the delivery spout while taking water.

A still further object of the invention is to provide a locking device of the above mentioned character which maybe readily and easily attached to the spout and the mast which extends vertically at'the side of the water tank, without necessitating any material alterations of the arts of the water tank with which the locking device is to be associated.

A further object is to provide a locking device of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.-

Uther objects and advantages of the in vention will become apparent from the following description taken in connection with the accompanying drawings.

In the accompanying drawings wherein like numerals indicate cornespondin parts.

Figure 1 is a fragmentary side e evation of a railroad water supply tank, the upper portion of the mast being illustrated and the locking device embodying my invention being shown attached to the delivery spout with the arts so arranged as to maintain the spout in a lowered position.

Figure 2 is a front elevation of the upper portion of the mast showing the manner in which the guide rod is supported between the uprights comprising the mast.

Fi ure 3 is a sectional view taken approximate y on the line 33'of Figure '1 looking in the direction of the arrows for more clearly disclosing the locking device.

Figure 4 is a side elevation of a saddle forming a part of the present invention.

Figure 5 is a sectional view taken approximately on the line 55 of Figure 1, and

Figure 6 is a detail perspective view of the locking bolt.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a water supply tank which is supported on the frame 2 in the manner well known in the art. An outlet pipe 3 extends from the bottom of the tank 1 and associated with the outer end of this pipe is the dellvery spout a. Extending vertically at the side of the frame and tank 1 adjacent the spout 4 is the usual mast designated generally by the numeral 5, the same comprising the vertically'spaced standards or uprights 6'and 7, respectively.

The parts thus far described are of the conventional construction and it is therefore thought unnecessary to further go into detail with respect thereto.

A bearing carrying strap 8 is secured transversely across the upper ends of these standards or uprights 6 and 7, the bearing being designated by the numeral 9. A similar cross piece- 10 is disposed transversely across the lower portions of the standards at a point above the inner end of the spout 4 as is clearly shown in Figures 1 and 2 of the drawings and the bearing associated with this cross member is designated by the reference character 11. The bearings 9 and 11 provide a means for supporting the respective ends of a vertically disposed guiderod 12, and a purpose of this guide rod will be presently described.

Slidable on this guide rod 12 is the head 13, the upper end portion thereof being bifurcated to form the parallel spaced arms 14 and 15, respectively, and the bifurcatedupper end portion of the head is disposed laterally as is clearly illustrated in Figures 1 and 5 of the drawin s. The bottom portion of the head 13 is ormed with an openin for a purpose to be hereinafter more fully descrlbed. A grooved pulley 16 is supported between the arms 1 l-and 15 on a transverse pin 17 and this pulley is adapted to engage the guide rod 12 in the manner also as clearly shown in Figure 5. A bolt 18 extends through suitable registering openings provided therefor in the outer ends of the arms 14 and 15 and a nut 19 is threaded on the threaded end of the bolt, the bolt being disposed on the opposite side of the guide rod 12, thus preve ting the displacement of the head member troni engagement with the rod.

Also torniing an important part of the present invention is a saddle which is curved to conform to the contour of the delivery spout l on which the saddle is to be mounted and for the purpose of securing the saddle on the spent, the saddle is formed at its side edges with the strap members ill and two pairs oil such strap members being provided and these strap members are also curved to conform to the contour of the delivery spout and the tree ends of the opposed straps are disposed laterally as at 23 and a belt 224: extends through suitable registering openings provided therefor in the laterally disposed free ends of each pair of straps 21 and 22. A nut 25 is threaded on the threaded end of the bolt and in this manner the straps can be socurely clamped around the spent to support the saddle 20 in a rigid position on the top of the spout Tillie specific manner in which the saddle is secured on the spout is more, clearly disclosed in Figure ol" the drawings.

l orined on the to 2 oi. the saddle and extending upwardly t ierefroni is the longitudinally extending bar or relatively thick plate 26, the rear or inner end. portion at which extends for a greater height than the torward end portion. A book E2? is termed at the upper torward edge portion of this bar or lined plate 2% and the purpose at this hook will also be presently described.

rln arcuate shaped slot 28 is termed in the rear upper portion of the upwardly projecting bar or listed plate and an opening i lll is also termed in the rear end portion at this bar or plate directly below the arcuate shapedslot in the manner clearly disclosed in Figure oil: the drawings.

1h lower head member 30 has its lower end. portion bifurcated to provide parallel spaced arms ill. and 32 respectively, and these arms straddle the upwardly projecting bar or lined plate 526 in the manner shown very clearly Figure 3. The upper portion oi the head member 3G is termed with an internally tl'ireadeol soolret into which is threaded the lower end at an elongated rod or arm the upper end of which is thread ed into the socket provided theret'or in the bottom of the upper head member 13. Suitable loch nuts 34- and 35 are associated with the lower and upper threaded ends of the red 33 and engage the respective head members :tor preventing the accidental displace ment oi the rod from engagement with the upper and. lower head members. This rod provides an operative connection between the upper head member which is slidable on the guide rod 12 and the lower head member 30 as is readily obvious -lrom the construction shown in Figure 1..

ll pivot lorming bolt 36' extends through suitable registering openings provided therefor in the free end portions of the arms 31 and 32 ot the bifurcated head member 30 and through the opening 29 provided in the rear end portion of the bar or fixed plate 26, and this construction provides a means whereby the lower head member 30 is adapted for vertically swinging movement with respect to the saddle 20.

The arm. Ell is provided with an elongated slot 37 adjacent the inner end thereof as clearly shown in Figure 8, and disposed within this slot is the substantially rectangular shaped head 38 formed on one end of the bolt 39 which is of a suitable length and which has its other end threaded as at lO. 'lhe bolt 39 extends through the arcuate slot 28 formed in the upper rear end portion of the bar 26., and through a suitable opening provided therefor in the other arm 32 ot the bifurcated head 30 as is also clearly shown in Figure 3.

it stationary cam ll. is secured on the threaded outer end oi the bolt 39 by the nuts ll-:2 and this cain i1 is spaced from the outer face ot'the arm 32 oi the head member 30. it notch 43 is formed in this cam 41 as is clearly shown in Figure 3. Adapted for cooperation with this cum &1 is the cam sleeve 4% which is adapted for rotation on the bolt 39 between the arm 32 and the stationary cain ll. 'lhe cain forming outer end oi this sleeve aid is also notched as illustrated at d5 for cooperation with the notched portion 43 oi the stationary cam ll and when the parts are arranged as shown in Figure 3, the head member 30 is tree to swing in a vertical plane over the curved upper edge portion it of the upstanding bar or fixed plate 526.

it lever l extends laterally train the sleeve and is provided tor the purpose of actuating the sleeve. "ll hcn the lever 47 is swung in one direction the sleeve a l will be rotated about the bolt'lhl and during the rotation ot the sleeve the cammed outer end the sleeve will cooperate with the stationary earn ll to cause the bolt 39 to move outwardly whereby the inner face of the head 38 will be brought into binding engagement with the adjacent lace of the bar or lined plate 26, thus securing the head member 30 in a locked position against swinging movement with respect to the saddle.

This action takes place when the spout -1- is swung to a lowered operative position, whereby the spout will be locked in such position against upward swinging movement, while water is being talreu from the tanlr.

or the purpose ot-assisting in returning the delivery spout alto its upwardly raised rir lllll nausea inoperative position after a sufiicient amount of water has been taken from the tank there is provided a chain 48 which is looped over the hook 27 formed at the forward end of the upstanding bar 26 on the saddle 20. The free end portions of the chain are disposed over suitable pulleys 49 which are supported on a shaft 50 which is disposed between the upper ends of the standards 6 and 7 of the mast 5, and a counterweight 51 is attached to the freeend portions of the chain in the manner clearly shown in Figure 2. Manifestly when the head 38 on the bolt 39 is out of binding engagement with the bar or fixed plate 26, the spout i may be swung upwardly and during the upward swin 'ng movement of this spout, the upper hea 13 will slide upwardly on the guide bar 12 and the weight 51 will support the spout in its raised inoperative osition.

Furthermore, this c ain and hook provides a means for reventing the accidental dropping of the de ivery s out, thereby preventingany possibility o a person being in'ured by the fall of the spout.

t will thus be seen from the foregoing description that I have rovided a locking device for securing the elivery spout of a railroad water supply tank in a lowered operative osition,thus obviating the necessity of a hreman having to hold the'spout while taking water. The simplicity of my improved locking device enables the same to be readily and easily actuated, and the same will at all times be positive and eilicient in carrying out the purpose for which it is designed.

tional head member adapted for vertically slidable movement on the mast, interconnecting means between the head members, and cooperating means between the lower head member and the saddle for locking said pivoted head member against vertical swingmg movement to hold the spout inc-a lowered position.
