HOSE-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 682,558, dated September 10, 1901.

Application filed January 4, 1901. Serial No. 42,104. (N o model.)

ToV all whom, it may concern:

Be it known that I, JOSEPH ScHENcK HOOKER LOVETT, a citizen of the United States,and a resident of Trenton,in the county of Mercer and State of New Jersey, have made a certain new and useful Invention in Hose- Machines; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to Io which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a plan View of my machine, partly broken away. Fig. 2 is an end view of the same. Fig. 3 is a partial front elevation of the same. Fig. Lillustrates the devices for insuring the rotation of the mandrel at zo the proper time. Fig. 5 illustrates the threeway valve G. Fig. 6 is a detail view of the part I.

This invention has relation to certain new and useful improvements in hose-machines,

and particularly upon the machine of'Iatent No. 612,766, granted to Samuel K. Wilson, beingI designed to secure pressure of the rollers upon the hose being wound which will be uniform throughout the length of 3o such hose, thus avoiding variation in the size of the finished hose, to provide improved automatic mechanism lfor starting the rotation of the mandrel or hose-pole at the proper time, to provide a yielding support for the 3 5 mandreldriving shaftv in order that such shaft may accommodate itself to the yielding roller-bed, and to provide means whereby the rotation ofthe mandrel or hose-pole may be stopped instantly and the upper or pressure 4o rollers raised to admit of the removal ,of

creases in the hose-windings.

With these objects in View the invention consists in the novel construction and combination of parts, all as hereinafter described,

and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates the main supportingframe of the machine, B B the double series of rollers forming the bed or support for the hose-pole or mandrel Y, and C O the upper 5o series of pressure-rollers, such rollers being Y carried b vrearwardly-extending spring-arms B and C', attached to collars B2 and O2, secured by set-screws upon common shafts. The shaft B3 of the upper series of rollers is 55 arranged to be rocked in its bearings by means of arms D ,extending rearwardly therefrom at intervals, carrying adjustable counterbalancing-weights D at their end portions and having a connection with upwardly-extending piston-rod extensions F of cylinders F, suitably supported from thev floor. These cylinders F have at their lower portions pipe connections with a source of compressed air or the like in order that upon admission of such to the cylinders t-he pistons F" thereof will be driven upwardly to rock the shaft B3 and lower the upper series of rollers upon the hose with the proper degree of pressure. This admission of iuid motive power is accomplished by means of a three-Way control and y exhaust cock G, connected by pipe g with the source of power and communicating with piping g' to the cylinders. Upon cutting off the compressed air from such cylinders the shaft B8 is rocked reversely under the influence of its counterbalancing devices, and the pistons fall inl their cylinders, the compressed ai r escaping through exhaust-port G in the cock G. It is essential for the proper operation of the machine that the mandrel or hose-pole shall not'commence to rotateuntil the rollers O Chave been brought into operative relation thereto and properly tensioned, and I have devised improved means for this purpose, as follows: H represents a crank at one end of rock-shaft B3. H is a rod extending' downwardly from the free end portion of said: crank, to which it is pivotally connected, and having a laterally-extending end portion h. Upon rocking shaft B3 forwardly rod H is Y thus moved downwardly, a cam-surface h of said rod acting upon a 'lateral extension t' of. pivoted catch I to rock the same and release spring-actuated arm j, carried by rock-shaft J to rock such shaft .I and effect the clutch to start the mandrelin rotation at the proper time. Rock-shaft .I has for this purpose an upwardly-extending arm K, having at its free l catch I,- the spring thereof being designated end portion a stud 7c, working in a slot 7c of lever L, said lever extending at its upper portion across between the forks and down upon the opposite side of bifurcated frame M, be-

ing pivoted at opposite sides thereto. The frame M is provided with bearings for the mandrel-driving shaft M', carrying spur-wheel N and clutch member n thereof loose thereon 1o and carrying opposing clutch member n sliding upon said shaft and rotatably connected thereto. The mandrel-chuck X is also carried by shaft M. The upper transverse portion of lever L has an upward forked extension embracing clutch member n and effecting the clutch therebetween and member n upon actuation of lever L. The frame M is provided with a central downward extension M2, passing through the upper cross-bar A of the supzo port therefor and through a second cross-bar A2 of such. support. This extension M2 has a collar m secured thereto by set-screw m', and upon opposite sides of such collar, surrounding the portion of said extension included between said cross-bars, are two coil-springs O and O', bearing at opposite ends thereof upon collar and cross-bars. At the lower end of extension M2 is pivoted thereto lever P, having pivotal bearing p in frame A and pro- 3o vided with an adjustable counterbalancingweight P'. Under movement of the yielding roller-bed B B the mandrel-driving shaft M will thus move therewith. Spur-wheel N is driven by spur-wheel N upon shaft N2, parallel to'the shaft M and carrying step-pulley NS. Shafts N2 and M are linked together at o 0 to maintain the proper degree of engagement between the teeth of wheels N and N. For this purpose also the shaft N2 has 4o bearings in boxes N3, provided with sliding bearings in frame A.

The operation is as follows: The hose-pole, with the inner tube orhose-lining thereon, is placed upon the carrying-rollers B B, and the strip of duck or other wrapping having been previously secured atone end to said inner tube air-pressure is admitted to cylinders F by cock G, the upperseries of pressure-rollers lowered upon the hose, and when properly 5o tensioned thereon the mandrel is automatically started in rotation -to wind such strip of duck, such winding being made smooth and uniform by the absolute accuracy of pressure iso far as is practicable by machinery) secured throughout the length of hose being wound, the pressure from cylinders F being communicated first to a rock-shaft, which acts as an equalizer, and from such shaft to the hoseinprocess of winding. Upon cutting 6o off pressure in the cylinders F the pressurerollers are raised under the influence of their counterbalancing devices and the mandreldriving shaft immediately stopped in its rotation through reverse movement of lever L,

accomplished by upward movement of armj by rod H, such arm being caught and held in its horizontal or raised position by springby I. The rapidity with which the mandrel may be stopped in its rotation and the pressure-rollers raised admits of the removal of creases in the hose-windings at the commencement thereof before such creases are covered, when it is too late for their removal.

In a machine of this character it is indispensable that the pressure be not applied direct to the hose, as such causes hard and soft places to appear in the finished hose by reason of the irregularities present in all stock, this having been heretofore the greatest objection to machine-made hose. rllhis defect has been overcome by dividing the pressure and carrying rollers into short sections, each section being carried by a spring arm connected to common shafts.

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