HOSE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 571,261, dated November 10, 1896. Application filed A ril '7, 1896. Serial No. 586,557. (No model.)

To (LZZ whom it puny concern.-

Be it known that I, ROBERT T. BURCHELL, a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Hose-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a front view of a machine embodying the invention. Fig. 2 is a plan View of the same. Fig. 3 is a trans- I verse vertical section on the line a; 50, Fig. 1.

Figs. at and 5 are detail views of the mandrelcenter, for one end'of the mandrel. Fig. 6 is a similar view of the center for the other end of the mandrel. Fig. 7 is a detail sectional view of the reel-carrier. Fig. 8 is a detail view of one of the slides H and its boxes, and Fig. 9 is a detail view, partly in section, showing the hanger J and a portion of the screwshaft which carries it. Fig. 10 is an end View looking from the left-hand end of Fig. 2. Fig. 11 is a detail View of one of the cutters.

The object of this invention is to provide a hose-machine of improved character; and it consists in the novel construction of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates the bed of the machine, which rests upon legs A or other suitable supports.

B designates a head-block at one end portion of the bed, in which and in a bearing B is journaled a short shaft B 13 is a driving-pulley loosely journaled on said shaft and having a clutch-hub B B is a clutch-section which is fixed to the said shaft, but is slidable endwise thereon into and out of engagement with the clutchhub 13*.

B is a fork which engages the said clutchsection B 13 is a compound shifting lever which is connected to said fork. The section B is pivoted and one of its arms has a mitered end nected to said fork.

O designates a mandrel, the head end of which has a squared portion c, in which is formed the hearing. The opposite end of the mandrel has a bearing on one of the centers now to be described. 0 C are the two centers which carry said mandrel and on which it revolves, the former being on the end of the shaft B and the latter j ournaled in a movable tail-block C at the opposite end portion of .the bed.

Fitted over the center O, which is the driving-center, is a cap G which has an angular socket therein of tapering form, its front end being larger than its inner or rear end, which is of the size of the squared portion 2 of the mandrel. The center 0 has a half-funnelshaped cap 0 In putting the mandrel in place its squared end is inserted into the cap and the other end is dropped into the cap 0. O is a collar secured adjustably on the center 0 C is a stout spring whose lower end is secured to the tail-block C and whose upper end portion presses against the said collar for the purpose of holding the center 0 to the mandrel, or rather to hold the mandrel against both centers. The collar 0 acts as a stop to prevent the said spring from exerting too much pressure upon the mandrel.

O is a lever fulcrumed to the tail-block C and whose upper arm is connected to the spring O". (l is a cord which connects the lower arm of this lever with a treadle C O is a bearing-pulley for the said cord.

D D are two rearwardly-curved arms which are firmly secured to the rear side of the bed A and which support a shaft D, which is parallel with the mandrel and of about the same length. Secured on said shaft by set-screws or otherwise are a series of adjustable collars E, each of which has connected thereto a downwardly and forwardly extending springarm E, the lower end of which has a fork E provided with bearings for a small roller The arms E are so disposed, as seen in Fig. 2, as to cause the rollers to break joints with each other.

F is a rearwardly extending counterweighted arm which is ad j ustably sleeved on the'shaft D and is secured by a set-screw. F is a forwardly and downwardly extending lever which is similarly secured to said shaft at the opposite end portion.

G G are two arms which are secured to the shaft D by collars and set-screws, one of said arms being at each end of the series of rollers. The forward ends of said arms terminate adjacent to the mandrel and are provided with clamps G, in which are secured cutters G H is a stand or table which is placed at the front of the machine and over which the duck or other material is fed to the mandrel.

H H are two parallel rollers which are journaled longitudinally in' the said table. H is a third roller which is journaled above the front roller H in vertically-movable slides H whereby said roller may be raised or lowered. These three rollers serve as tensionrollers to govern the feed of the duck and prevent it from lapping over while it is being fed to the mandrel.

The slides H work in the boxes II. (See Fig. 1.) Connected to the lower end portion of each slide is a cord H These cords extend up through the grooves 71 of the boxes 11*, and, passing over the bearingpulleys h", are connected to a treadle H.

The rear edge of the table II has, adjacent to the mandrel, anedgewise-disposed piece or flange 71 over which the duck after it leaves the rollers H H is fed to the mandrel.

Journaled over the mandrel in standards I is a rotary shaft I, having cut thereon a helical thread 1; of considerable depth. Said shaft is driven by a belt or other connection with the shaft B, as indicated.

J is a hanger in which is journaled a wireholding reel K. Said hanger consists of a semicylindrical traveler in whose concave face is cut a thread 76, which fits the thread of the shaft J. Cast on the upper surface of this traveler are two lugs 7c, having each a bearing in which is a set-screw W. The two lateral portions of the hanger or reel-carrier have hooked upper end portions which extend under the lugs 7c and are secured by the said screws. (See Figs. 1 and 9.) Connecting the said lateral portions a short distance above their lower ends is an adjustable cross-piece K having therein a wire-guide The reel K is journaled upon a bolt 70 On the headed end of said bolt is a sleeve-collar 7a and at the opposite end is a thumb-screw 7.9 WVhen said screw is turned in the right direction, the head of the bolt is drawn against the collar I and the latter against the frame of the hanger. In this manner the reel may be put under more or less friction to regulate the feed of the wire therefrom.

The operation of the machine is as follows: The lever F is thrown up, thereby raising all the line of rollers E The foot is now placed on the treadle I-l", thereby raising the slides 11 and the roller H The rubber tube to be wound having been slipped upon the mandrel, the latter is placed upon its centers, to

permit which the treadle C is depressed. The foot is now removed, and the center C closes upon the mandrel. The edge of the duck with which the tube is to be wrapped is now brought to the tube and the treadle II is released to permit the roller H to drop. The rollers E are now lowered. The lever F in dropping comes in contact with the compound shifting lever, which action, by means of the mitered contact of the two sections of the said levers, throws the clutch in gear and sets the mandrel in motion. The duck now commences to wind upon the tube. During the winding the lever F is pressed down with considerable force, causing the rollers E to exert pressure on the duck as it is wound, their spring-arms permitting them to yield to seams and other irregularities thereof.

hen the duck has been wound, the lever F is thrown up, which releases the shifting lever. The clutch is now thrown out of operation by means of a suitable spring, as S. The knives or cutters, before described, having been set at the required distance apart, the hose will have been cut thereby during the winding to the required length. The mandrel is now removed. In the operation as thus described the screw-shaft I is,

thrown out of operation, being used only in the operation of winding and applying the cord in making corrugated hose. In this operation, the screwshaft being revolved, the hanger which carries the reel is fed along said shaft by its rotation. The wire is delivered to the mandrel, one ply of duck is wound over the wire, and a gum tube is placed over the duck. Another ply of duck is then wound, another of gum, then a wrapping of muslin, after which the cord is applied.

I desire to state that I do not limit myself to the exact construction and arrangement of parts as herein shown and described, it being obvious that these may be varied somewhat without departing from the spirit and scope of my invention.

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