JERSEY, AND ONE-THIRD TO WILLIAM WALLACE FEEDING MECHANISM FOR HOSE-MAKING MACHINES.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed November 20, 1907. Serial No. 403,105.

T o all whom 'it 'may concern:

Be it known that I, JOsEPH ScnnNox HOOKER Lovnrr, of the city of Trenton, in the county of Mercer, in the State of New Jersey, one of the United States of America, have invented certain new and useful Tmprovements in Feeding Mechanism for Hose- Making Machines, of which the following is the specification.

My invention relates to improvements in feeding mechanism for hose making machines, and the object of the invention is to devise a machine which will quickly and automatically deliver the canvas, cut and prepared by the cutting machine, ydirectly to the hose making machine and also attach the rubber strip forming the outside jacket of the hose to the canvas body preparatory to its being wound by the completing machine and it consists essentially of a rectangular frame, T-shaped standards secured in bearings to each end of the frame and capable of vertical movement therein, mechanism actuated from the driving shaft of the cutting machine for imparting such vertical movement to the T-shaped standards, rollers journaled at their end in the standard, supplementary bearing standards located at each end of the aforesaid frame, cross shafts journaled in the supplementary standards, pulleys mounted on the cross shafts intermediately of the rollers, belts extending between the pulleys at each end of the frame and located between the rollers journaled in the main frame, mechanism for driving the belts from the main drive of the cutting machine, grooved wheels secured on pivoted arms in proximity to each end of the machine and means for adjusting the height of such wheels as hereinafter more particularly described by the following specification.

Figure 1 is a general perspective view of my machine attached to the driving mechanism of a cutting machine. Eig. 2 is a plan view of my machine. Fig. 3 is an enlarged cross section of my machine.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the main frame, rectangular in form.

A are vertical bearings located to the inside of the end bars of the frame A.

B are T-shaped standards the stem B of which are held in the bearings A y andmthe cross heads B2 of which are provided with bearing notches B4.

B4 are a series of rollers extending longitudinally of the frame and having pintles extending from the end thereof1 which rest in the bearing notches vB3.

O is a driving shaft, driven from a suitable source of power and journaled iny bearing bracket O in the base of the frame A.

O2 is a pulley thereon and C3 is an endless cord or belt extending around the pulley C2 and around the grooved portions B5 of the rollers B4.

B6 is a rock shaft journaled in the brackets in the main frame A.

B7 is an arm secured to the rock shaft BG.

B8 are cams secured to the main driving shaft D of the cutting machine D.

B1 is a link pivotally connected at one end to the arm B7. The other endof the link B9 is provided. with rollers B10 engaging with cam grooves formed in the inner faces of the cams B8. These grooves are of any shape suitable for imparting a rocking movement to the arm B7 through the link B.

B11 are cam arms secured to the -shaft BG and engaging the lower end of the stems B.

E, E are supplemental bearing standards. E2, E3 are cross shafts journaled in suitable bearings.

E4, E5 are series of pulleys located opposite the space between each pair of rollers B4 at each end of the machine respectively.

E6 are endless belts extending around each pair of pulleys, E4 and E5, located between each pair of rollers B4.

The shaft E2 extends beyond its bearingv standards towards the cutting machine Dl and is provided with a bevel pinion E7.

E8 is a supplementary shaft journaled in bearing in the main frame of the cutting machine.

E9 is a bevel gear secured to the end of the shaft E8 and meshing with the pinion E7 in the shaft E7.

E10 is a ratchet wheel scoured to the shaft ES.

E11 is'a rock arm swung On the shaft E8 and E12 isa pawl engaging with the ratchet E10.

E13.V is a link pivoted to the rook arm E11 and provided with rollers E14 at its opposite end.

E15 is acam secured to the main driving E2 and F/ and the shaft E3 with its corresponding shaft F. The gears are proportioned so as to drive the wheels F2 in unison with the belts E11.

The arms F are provided with extensions F5 extending at right angles to, and opposite to the pivot points of the arms.

F6 is a lever and quadrant which are connected by links F7 to the extensions By this arrangement the height of the wheels c may be adjusted to suit various thicknesses of material.

Having described the principal parts involved in my invention, I shall briefiy describe the operation of the same. The steel pole 2 on which is held the rubber tube 3 forming the base of the hose is placed in position in the grooves of the wheels F2. The canvas as it passes from the cutting machine, is drawn by the revolving rollers B1 into the table A. The required width of material 4, (see Fig. 3) is fed into the table and severed from the main body and the cam B8 operates. It will be noticed in referring to Fig. 3 of the drawing that the inner edge of the canvas falls when cut from the main body onto rubber covered pole to which it is suitably cemented. By the operation of the cam B2, the cam arms B11 are rocked from beneath the stemsB of the T-standards B; The standards B and the rollers mounted thereon are depressed thereby lowering the portion of 'canvas or other material su ported there by onto the belts EG. The bellfs are then revolved by means of the cams E13 which rotate the shaft Es through the ratchet and pawl E9, the shaft E8 being connected by the evel gears E7 and E2, to the shaft E2. The belts E6 are revolved sufficiently by one movement of the ratchet and pawl E to convey the canvas almost past the front of the cutting machine. The rear end of the canvas strip is thereby left in front of the cutting machine so that the next piece of canvas as it is fed from the machine overlaps the one previously fed enabling the strips to be cemented together end to end. The rollers H press these end portions together as the canvas is conveyed forwardly.

E are pulleys placed intermediately of the pulleys E5 and support the belts E15 which serve to carry the canvas on to the hose making machine.

5 is the rubber jacket or outer cover of the of the canvas previously to its being fed forward by the conveyer belts. n The outer roller H forces the cemented portions of the jacket and canvas together.v

From this description it will be seen that l have devised a simple form of conveyer which will quickly and automatically feed the canvas from the cutting machine to the hose making machine.
