SHOE-UPPER TURNING AND BEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 432,902, dated July 22, 1890. Application filed May 17, 1889- Serial No. 311,155. (No model.)

To all whom it may concern} Be it known that I, SIMON Ross, J r., a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Shoe-Upper Turning and Beading Machines, of which the following is a specification.

My invention relates to an improvement in shoe-upper-turning machines; and it consists in the novel construction and arrangements of devices for performing the different steps of the operation in a more satisfactory manner than has heretofore been accomplished.

One of the objects of my invention is to provide ahousing within the base of the machine for the operative parts, and to catch and hold the oil and prevent it from being dropped on the work.

Another object of my invention is to provide means for operating the machine without any sensible jar and making a comparatively-noiseless machine, as well as to operate the parts positively and construct the same cheaply, all of which will be fully set forthin the description of the accompanying drawings, making a part of this specification, in which Figure 1 is a front elevation of my improvement with apart of the shell-base broken off to show the operative parts. Fig. 2 is a central vertical section on line a: as, Fig. 1. Fig. 3 is a bottom plan view with the base of the machine removed. Fig. at is a diagram of the operative parts. Fig. 5 is a section of the rock-shaft shown in Fig.

A represents a hollow standard, which springs from the top of the shell-base of the machine and contains an upright shaft B which is reciprocated by appropriate mechanism, and the end of which is flattened to serve as a turning-iron to open the scallop. This shaft is normally held within the casing A, as will be hereinafter explained.

C represents an upright standard provided with overhanging arm D, forming one of the jaws of the heading mechanism. The stand ardA is mounted upon the base E, which is made hollow to receive the working parts,

and is hinged to the bed-plate F. This bedplate is provided with an exterior ledge a, into which the rim Z; of the base E seats, making a firm support of the base on the bedplate.

. represents the hinges; (Z, the hasp or hook for fastening the base E to the bed-plate F.

The working parts of the machine are inclosed in the housing of the base, which may be readily swung back on its hinges to allow the parts to be examined or oiled. The bedplate is cup-shaped, and catches the oil and prevents it from coming in contact with the work.

In the operation of this machine itis sometimes desirable to oscillate the beading-jaw 1 in unison with the reciprocation of the turning-iron B. It is also desirable to regulate the stroke of the turning-iron as well as the tension to be applied upon the jaw 1. This I accomplish by the following instrumentalities: 2 represents a driving-shaft Vjournaled in the sleeve 3 of the frame. -.t represents a pulley for conveying motion to the said shaft. 5 represents a crank-pin. 6 represents a wrist, which journals on said crankpin.- It is provided with a horizontal crank 7 and an upright pitman c to convey motion to jaw l. Crank 7 conveys motion to link 8, which is journaled to the crank-pin 10, attached to arm 11, which is keyed to the rock-shaft 12. This oscillating arm 11 is preferably beveled off to form a way for the sliding block 14, which is reciprocated thereon. Said slide 14 carries stud 15, which is keyed thereto.

16 represents a connecting-rod j ournaled at one end to the stud 15, and the other end is hinged to and reeiprocates shaft B.

19 represents a bell-crank lever, one end of which is hinged to the link 18, which link journals upon the stud 15.

20 represents a stud in the frame, 011 which the bell-crank lever journals.

21 represents a treadle-rod hinged to the upper end of the bell-crank lever 19.

2 represents a spring attached to the bellcrank lever 19. Its tension is adjusted so as to hold the slide 14. and its crank-pin 15 nor mally opposite the center 12 of the oscillating arm 11. In this position the oscillation of arm 11 rotates stud 15, but imparts nomotion to the connecting-rod 16 and shaft B. As this slide 14 is moved away from the center 12, the oscillation of the arm 11 will impart motion to the link 16 and reciprocate the shaft B. This movement of slide 14 is controlled by means of the treadle 21, bell-crank lever 19, connecting-rod 18, so that the slide 14 may be moved down upon the oscillating arm 11 and give the least or the extreme motion to the turning-iron. As soon as the strain upon the treadle device 21 is removed the slide 14 is drawn back by the spring 22 opposite the center 12, and no motion is imparted to the link 16.

to be imparted to crank 15, the operator applies strain to the treadle 21 to draw the bellcrank lever 19 down, and hence remove the slide 14 down on the oscillating arm 11. The distance that the turning-iron B projects up from the pyramid of the casing A is thuscontrolled by the operation of the footlever. Said bar may be projected to the point 2'; but when the parts are in a normal position it occupies a position within the casing A, as

shown in Fig. 1. Hence turning-iron maybe controlled for any kind of work by the foot of the operator. In order to reciprocate the beading-j aw 1 and beat down or compress the work placed between the jaws 1 and D, it is essential that the motion be a cushioned or elastic one for two reasons-first, to prevent noise, and, second, to prevent cutting or abrasmg the material. This is accomplished by means of the Wrist 23, which is provided with plunger 24, that reciprocates against the spring 25, placed in a socket 27 in the heel of cross-arm 26, and is coiled around the rod 28. 29 represents a cushion, preferably made of rubber, between the nut 30 and the crosshead 26'. Now as this spring interposed between the plunger 24 and the cross-arm 26 is the medium by which motion is conveyed to the jaw 1, the operation or the pinch of the jaws 1 and D is a soft or increasing one, the rigidity of the spring 25 being the controlling element. \Nhen the spring 25 is compressed by the forward motion of the plunger 24, the tendency is to lift the nut 30 off of its base by the pressing up of the plunger; but

cushion 29 prevents a hammer or shock on the return or downward movement of the plunger 24, thus rendering the operation of the parts noiseless, as well as taking off the jar.

It will be observed in the operation of this machine that the motions are conveyed from the main driving-shaft to the compressinaw by means of cranks and links, and that these operate against springs, so that the motion of As motion is desired work, and accomplishing the obj ect ofa header in amore satisfactory manner than the machines of this class heretofore'employed.
