To all-whom it may concern Be it known that I, EDGAR D. RoMANs, a citizen of the United States, residin at St. Paul, in the county ofRamsey and tate of Minnesota, have invented a new and useful ingz cylinder for the impelling liquid; Heretofore trouble has'been encountered in constructing manifold" brackets of the class stated, from blow holes in the material constitutingthebracket, which, owing to the high pressure of impelling-liquid employed for lifting heavy loads, weaken the material to a point at which openings occur and permitthe impelling liquid toleak and escape,

thus rendering the apparatus ineffective'or at best inefficient and troublesome. My in vention primarily is designed to overcome this objection in a simple and inexpensive manner.

My inventionfurther enables the parts mentioned to be arranged and assembled in compact form, thereby economizing space,

producing greater efliciency and effectiveness in operation of the working parts and unifying the structure as awhole so as tosimplify and reduce tendency of the parts getting out of runningorder. The unification of the parts also reduces cost of production and saves time and material in ap plying the parts to a motor truck for use.

With these and other objects and advan-- tages in View, my'invention comprises the features of construction and combination of parts hereinafter particularly described and claimed. j y

In the accompanying drawing forming part of this specification, Fig. 1 is an elevation showing a detail ofthe lower end of a hydraulic hoisting cylinder mounted on its support and to which my invention is shown applied, the'drive shaftof the vehicle beingv shown; Fig. 2 is a perspective View ofmy Specificationof Letters Patent.

improved manifo1d bracket when removed from the vehicle,-and Fig-.' 3 is a cross 'sec-. tion taken along a line 3"3 in Fig. 2. 1

A In the drawing,"A indicates thelower end of a hydraulic hoist cylinder whichis common-ly employedupon motor truCksfo-rraising and lowering the truck body into and out of dumping position. The lower endof-this cylinder is shown provided with the usual combined cylinder-end and base 10, which 1 is supported. upon the chassis of the. motor truck inthe'usual manner, such as by angle bars'lL B indicates the'longitudinal main 1 drive-shaft of th'e'vehicle,-which transmits power from. the primemov'er to thelrear In operating the hoist, impelling liquid is employed,.such as oil or othervliquid, which P l is forced upwardly under great pressure into thei lower end of-the cylinder and'pro'jects.

the piston therein,"f"said impellingliquid being forced byxa pump 'C'of' geartype or, I

any other construction. Thispump has the usual pump casing 12 containing an outlet 8,0

port v13,- through which the inipelling liquid is projected and valve mechanism 14L connected with an ingress or return duct15 leading from the upper-end of the cylinder above the piston, saidvalve casing being provided i with a valve operating shaft .16-whichisop;-

erated byfthezgcrank arm 17"and. connecting rod; 18 leading upwardly to a: convenient position for the operator to actuate. The pump also has a main driving shaft 19' for 'actuatingits fluid impelling gears, said shaft being shown operated by a sprocket wheel 20, although it may be operated by any.actu

ating device'. The parts described are all of ordinary construction common to hoists for dumping bodies.

Power-for drlving the pump" originates in the drive shaft B of the vehicle-audiehydraulic 1 connected with the pump' by a clutchD, a

driving sprocket .21.]in alignment with sprocket 20 andanchain belt 22 traveling shifting fork 23Ym'ounted upon the rock oversaid sprockets. The clutch has theusual arm 25 and actuating rod 26 for shiftingthe I clutch to actuate or stop the pump.

My improved manifold bracket E consists tion being formed with a top plate 40 ,iwhich is secured to the lower'surface of the coinofa skeleton frame, which, as illustrated, is ,f i .of rectangular form, the outer frame porthe manifold bracket has a body portion 43 resembling a web depending from the plate 40, at the lower end of which and at one side of the shaft B,'free from the "clutch, is

a horizontal, rectangular plate 44:, to the lower surface of which the pump C is secured by bolts 45, or other means. The side of the web or body 43 is formed with bearings 46 in which the rock shaft 24 is-journaled in transverse position above the clutch and shaft B. Thus, the manifold bracket is designed to support the pump and the rock shaft inconvenient position to be driven by the drive shaft and to actuate the clutch. I The manifold bracket is also formed with a duct or channel 47 traversing the web and connecting the lower end of the cylinder through the end plate and'supportlO with the port 13 inthe pump C. The material of the web is enlarged around the duct 47', a

- flanged boss 48, being formed on the opposite sides of the web to re-enforce the strength of the web and to minimize the amount of material necessary in producing a strong and durable structure. As stated in the introduction to thisspecification, considerable trouble has been encountered from leaks occurringthrough thewallof the duct which connectsthe cylinder with the pump forttransmitting the impellino: liquid. This objection I have overcome bycasting a thin tube 49 .into the manifold bracket in posithe bracket, thus reducing likelihood of leaking through the wall of the duct as heretofore. The, tube lining-may be of-any shape desired and enables the use of lower grade material constituting the bracket than heretofore. An intimate bond between the lining and wall of the casing, forming the passage between-the cylinder and pump, is

produced by casting the material of the bracket around the tube.

- Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a hoist cylinder,

a bracket at the lower end of said cylinder bracket and forming a conneotionbetween said cylinder and pump. I 3. A manifold bracket for the cylinder and pump of a hydraulic hoist, consisting of a depending web having a lateral'fastening plate at its upper end and a pump supporting plate at its lower end disposed in ofi'set position below the upper plate and an antileaking tube incorporated into said web and opening upwardly and downwardly respectively through said upper and lower plates.

4:. A manifold bracket for the cylinder and pump of a hydraulic hoist, consisting of a depending web having a lateral fastening plate atits upper end,-a pump supporting. plate at its lower end disposed in ofl'set position below the upper plate and bearings on the side of said web in which .an actuating shaft may be journaled, and an "antileaking tube incorporated into said 'weband opening upwardly and downwardly respectively throughsald upper'and. lower plates.

In testimony whereof, I have name to this specification.
