IMPROVEMENT IN MAUHINES FOR RIVEIING BUTTONS TO FABRICS.

TO ALL WIIOM IT MAY OONCERN:

Be it known that I, W. J. GORDON, of Philadelphia, Pennsylvania, have intented a Riveting Press for Securing Buttons to Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists of certain mechanism, described hereafter, whereby buttons can be riveted to articles of wearing apparel with ease and rapidity; the mechanism being such as to adjust both button and rivet to a proper position before the former is secured; the riveting being eitected by the combined'turning and gradual pressure of a punch against the-shank of the rivet, instead of the usual processof imparting ablow to the same, and the objectionable sharp edges of the head being forced out of the way into the fabric.

In order to enable others skilled in the art to which this most nearly appertains to make and usc my inven tion, Igvill now proceed to describe its construction and operation.v Ou reference to the accompanying drawing,-

n'hich forms a part of this spocication* Figure is a vertical section of my improved button-riveting press.

Figure 2, an exterior side view.

Figure 3, a front View; and

Figure 4, a diagram illustrating my invention.

Similar letters refer to similar parts throughout the several views.

The framework of the riveting press consists in the present instance of the base A and arm B, cast one piece. Ihe construction and form of the frame may, however, be modified Without departing from the main features of the invention. In the arm B, near the outer end of the same, is an openngfor the reception and guidance of' a spiudle,'D, which can .both turn and slide vertically in the said opening. A shoulder, e, is formed 0n the spindle, and between this shoulder and an annular projection, x, intervenes a spiral spring, L, the tendency of which is to force the spindle upwards. The spindle terminates in the pressing-punch z', which is pointed at the end as shown in the drawing, and which ts snuffly, but so as to slide freely iu an opening in the bottom of the sleeve E, the latter being fitted snugly, but so as to slide freely on the spindle D, to which the sleeve is connected by a pin, m, in such a manner that it can have a limited vertical movement independent of the spindle, which, however,Y on being elevated above this limit will carry the sleeve with it. A spiral spring, n, intervenes between a shoulder, g, on the spindle and the upper edge of the sleeve, so as to depress the latter. A handlever H is hinged by a' pin, t, to projections, pp, on the arm B, and on one side of this lever is a projecting rib, w, the bevellcd edgeof which is eccentric with the pin t; the said bevelled edge being arranged to bear against the conical or bevelled top of the spindle D. The button b, which has to be' riveted to the fabric d, has on the under side a projection, formed by making a cavity in the upper face, and to this cavity is adapted a projection,

'31', o he bottom of thel sleeve E. Then the hand-lever H is elevated and thrown back, the spindle D is raised by the spiral spring h, carrying withit the sleeve E to such a height that it cannot interfere with the ready adjustment of the rivet, fabric, and button to their places. The shank of the rivet O is passed through a hole in the fabric and through the button, and the whole are so adjusted that the convexhead of the'rivet will rest in a concave recess formed in the base A of the frame immediately'below the centre of the spindle D. In the end of the rivets shank is a conical recess adapted to the pointed end ci' the pressingpunch z'. When the lever Il is delr ressed, the eccentric bevelled projection w will force the spindle D downwards, thereby permitting the sleeve 4 E to descend simultaneously with the spindle, its projection, x, fitting into the cavity of the button, which is thus f lused to assume its proper horizontal position; at the same time the pressing-punch t' takes its place in the coniczil recess in the end of the rivet, and, should the latter not be adjusted in a vertical position in the first instan ze, the descending pointed pressure-punch will soon right it, and adjust it to a proper position for receiv= ing the final pressure, which is eiected by a further depression of the hand-lever. The moment this pressure is yapplied the resistance presented by the rivet causes the bevelled edge of the eccentric projection w to bear with such foi e. against one side of the conical top of the spindle that the latter must turn simultaneously with the descent e* the punch, which expands the end of the rivets shank and eiiectually secures the button to the fabric. Thr ect of this combined pressing and turning action of the punch on the shank of the rivet is very different fror at of a blow imparted to a spindle which does not turn, as the former plan is certain to result in a. uniform expansion of the end of the rivets shank, which presents aI neat appearance; Whereas a blow imparted to the lpunch might insmany cases distort the end of the shank and render the same unsightly. It will be observed on reference to fig. 4 that the cavity inthe base A of the frame for the reception of the rivet's heedy does not coincide with the letter, but that the-cavity isdeeper than the heed, so that the edges of the latter will be forced upwardshand compressed into the fabric when pressure is eppliedto'the rivetg'the objectionable exposure of sharp edges istlius avoided. Teeth may be formed on the bevelled edge of the eccentric projection 'w for gea-ring into similar teeth on the conical top of the spindle, to render the turning of the latter certgtinbut this will be unnecessary if proper A"cere be teken in the 'formation of the bcvelled edges of the 'eccentric and spindle.

.I vclaim' as my invention,and desire to secure by Letters Patent- The lever Hin combination with the spindle D, having a. pointed projection z', when the l'cver is provided with a. bevelled eccentric projection w, or its equivalent, and when the spindle is so 'constructed and arranged in respect to the lever that, on operating the letter, the spindle will turn round es it descends,l for the purpose speeied. A

2. .The combination of the above with the sleeve E', having a. projection adapted tothe cavity in the button, and with the springs h and n, the whole being arranged for joint action', asnnd for thelpurposc described.

3. Theconcavity so formed in the base A, in respect to the head of the rivet', and to the devices for spreading the letter,l that on forcing the rivet into the scid conoavity the edges of the said vhead will be turned up, as und for'the purpose described.l

In testimony wliereofl hav-c signed my name to this specification' in thc presence of two subscribing witnesses.
