DERRICK FOR VEHICLES.

Specification of Letters Patent.

Patented June 29, 1920.

Application led September 22, 1919. Serial No. 325,364.

a derrick having a telescoping .boom for use upon a motor truck which is capable y of extension to different heights without in" any way jeopardizing its stability.

Another object of this invention is to provide a derrick of the type referred to having a telescopic supporting part and means whereby the braces or guys can be easily adjusted to more edectively support the load raised.

A further object of the invention is the provision of a derrick for use upon fire hose-wagons or trucks fitted with means whereby the hose can be expeditiously raised near to a burning building and the.

nozzle or nozzles thereof manipulated while the fireman is effectively prevented from injury due to his close proximity to the confiagration.

A still further object of this invention is the provision of a simple and efficient portable derrick for use upon power driven vehicles.

With these and other objects in view as will hereafter be more apparent my invention consists essentially in the features of construction, combination and arrangement of parts hereinafter fully described, and more specifically pointed out by the appended claims.

In the further disclosure of the invention reference is to be had to the accompanying drawings constituting a part of this specification and in which like characters of reference designate the same or similar parts in all the views.

F 1g. 1s a side view of the same.

E Fig. 8-is a fragmentary side elevation of the firemans protecting and hose elevating cage with part broken away to disclose the underlying structure.

Flg. 9-is a vertical section of the same, and taken at right angles to the preceding figure.

Fig. 10--is a detail of one of the hose nozzles and,

Fig. 11-is a similar View of a slightly modified form of nozzle.

Referring to the drawings, the numeral 10, designates thechassis of a motor truck of any approved type, 11 the wheels thereof, and 12 the motor and associated parts all of which are in accordance with generally accepted pattern, and which form no part of my present invention.

The drivers seat is designated by the numeral 13, and immediately in the rear thereof I construct a suitable supporting base or platform 14, which extends transversely of the chassis 10, and integral with or mounted on this platform 11,1, is a truncated housing 15 for the clutch and winding mechanism hereinafter more specifically referred to.

Mounted on top of the housing 15, as for example on an antifriction ball bearing 16, 1s a turntable 17, Fig. 3- which supports the lower section 18, of the derrick standard.

swung from side to side of the truck as desired. Fitting in the aforesaid section 18 and adapted for raising or lowering therein is a second, or upper section 24, and in order to providea simple and eifective means for raising and lowering the same I fit a co1-4 lar 25 on the upper end of the lower section 18, provided with a bearin for a sheave 26,'

over which passes a cable 2 one end Where-l .of is attached tol the lower end of the secare upstanding bearings 33, between whichl is hingedly mounted 'the forked end 34, of a boom 35. This boom 35, preferably includes a' series of telescopic sections b, o, and d, the section a, having the forked end 34, and the sections b, 0,' and d, being adapted to telescope within one another and the said section a. Each section a,l b, c, and d is made up of anglef sections 36;. Fig. 5.- braced by lattice work 37 into box formation, and each said section is provided at its outer end with a collar 38, yhaving opposed sheaves and e es 40, 41, respectively mounted thereon, t e former for example being disposed on the lower side of the boom 35.

' At the lower inner end of each of the sections b, c, and d there is revolubly mounted a sheave 42, and over said sheaves 40, 42, there is passed a' cable .43, zigzag fashion the upper end whereof is secured at 44, to the upper end of the section d, and the lower end is conducted over sheaves 45, down to a winding' drum ,47,-Fig. 2-located in the housing15.

Connected with the aforesaid eyes 41, on the sections b, c, and d, are cables 46, which bly mounted at the uper end of the spaced l 'standards' 30,'thence ownwardly through the supporting sections 24, 18 to a winding.

drum 52-Fig. 2-and this cable 49, serves to ralse or lower a cage or the like 53, as

the case may be and according to the service conditions of the derrick. Stay or y ropes or cables 54, are vattached to the oi'- ward ends of a substantially U-shaped channel section 55, the parallel limbs -56 whereof are adapted for sliding movement longitu dinall of the chassis 10, and in order to provi e a simple -means for adjusting same l to -the requisite position they are provided with slots 57 through which bolts o r studs pass over the three uppermost sheaves 31,v

at the top of the section 24 and down through the same to a series of clutch oper,

-ated winding drums 47, adapted to be thrown into and out of action by suitable levers 48,-Fig. 4-under the control of the driver. These drums 47 may be controlled in any of the well known ways step by step and they serve in use to collapse the boom 35, or, in other words to move the sections b, c, and d, longitudinall into telescoped relation with respect to t e section a.

A fourth cable 46 is connected to the eye '41, at the outer end of the boom, section a and passing over the lower sheave 31, downwardly through the supporting sections or post 24, 18, to another windin drum 47, serves in use to raise and lower t e boom 35 from a substantially horizontal to the vertical or other desired inclination.l

A cable 49, supports at its outer end a block and tackle 50, and the other\end thereof passes over a pulley or sheave 51, revolucorrespondingly adjusted so 58l are passed andthreaded into the chassis 10. ',Ihus it `will be readily seen that when y the supporting sections 24, 18-are fullyvextended the guy ropesor stays 54 may be t atthe proper stability of the derrck is effectively maintained. v

Referrmg now more particularly to Figs.

8 to 1-1, inclusive, I illustrate thereby a con-- venient form of hose elevating cage and firemans protective cage 53, said cage being provided with swing doors 54, 54, throughv which ingress and egress may be effected, as well as a trap door 60 in the ioor thereof through which an emergency seat 61 can be lowered or raised by a cable 57 in case. of accident or when a rescue is to be effected from a burning building, the cable 57 being passed over a sheave or pulley 63, and connected'to a winding drum-not shownin the aforesaid housing 15. Hose connections 64 are coupled to a transversely disposed pipe 65 conveniently su ported on hangers 66, bolted or riveted to tliecage 53 and having adjustable nozzles 67, attached therein by means-,of which water can begplayed on to a burning building, at any desired angle.

Additional hose connections 68 may be attached to a plate bar 69, supported on hangers 70, at the front of the cage and having lfixed nozzles 71, attached thereto by means beneaththe chassis 10, and driven by a worm gear 75, on-the engine or motor shaft 76, additional chains not shown passing from the sprocket wheels 77 to the winding 'drums 52 for effecting their operation as and when required.

From the foregoing description it will be readily seen that by my invention I provide ratus, all of the operations being controlled from a single motor or engine shaft w1thout the driver leaving his seat on the machine. Furthermore a derrick embodying the foregoing described features will be seen to be extremely effective when applied to a V fire-hose truck whiley a fireman or firemen/ may be transported to any desired height to effect a rescue or play water on to a fire rapidly without the necessity and encum-` brance of hauling u-p the hose.

Finally while I have outlined one practical and convenient 'embodiment of lmy invention it will be readily seen that Variousv changes may be made in the particular form and arrangement of the several-parts Without departing from the essential features set forth, and hence I do not limit myself to the precise details specifically described, but consider myself at liberty to make such other changes and combinations as fairly fall within the spirit and scope of the appended claims. f
