EYELET OR SIMILAR MACHINE.

SPECIFICATION forming part of Letters Patent No. 688,134, dated December 3, 1901.

Application filed September 13, 1901. Serial. No. 75,288. (No model.)

To all whom it may concern:

Be it known that I, HENRY '1. SPERRY, a citizen of the United States, residing at Waterbury, county of New Haven, State of C011- necticut,have invented a new and useful Eyelet or Similar Machine, of which the following is a specification.

My invention relates to the various classes of machines-for example, eyelet-machinesto which employ one or more reciprocating punches in connection with a slide reciprocating in a plane at right angles to the plane of reciprocation of the punches and carrying the article being operated upon from one die I to another; and my invention has for its object to so improve the construction of machines of this type as to permit convenient access to the slide for the purpose of adjustment or removal.

It is of course well understood that each time a change is made in the work-as, for instance, a change from one size or style of eyelets to another or a change from one article to another-the dies, punches, and carrying-fingers must be changed, and in order to change the carrying-fingers it is necessary to take the slide out of the machine. This has heretofore been an item of considerable expense owing to the time required to take out the slide, it having been impossible as machines have heretofore been constructed to remove the slide, unless it was an exceedingly narrow one, without removing a number of parts of the machine, which required to be replaced and adjusted with care, an operation requiring considerable time and the services of skilled machinists. My present invention enables me to remove and replace the slide without appreciable loss of time and without difiiculty, thereby dispensing with the services of specially-skilled machinists. In order to obtain the desired result, I have devised the novel improvement in this type of machines which I will now describe, re- 5 ferring to the accompanying drawings, forming a part of this specification, and using reference characters to designate the several parts.

Figure 1 is an elevation of a machine of the character described, illustrating the application of my novel improvement; Fig. 2, a section, on an enlarged scale, on the line 2 2 in Figs. 1 and 3; and Fig. 8 is a section on the line 3 3 in Fig. 1.

The machine illustrated might be considered to be an eyelet-machine or any machine of a similar character adapted to make small articles from sheet metal by means of punches and dies.

10 denotes the framework of the machine, which may be of any ordinary or preferred construction or design; 11, the punches; 12, the upper shaft by which the punches are operated; 13, the ejectors; 14, the lowershaft, by which the ejectors are operated; 15, aslide by which the articles to be operated upon are carried, (the carrying-fingers themselves not being shown in the drawings, as they form no part of my present invention,) and 16 a vertical shaft which receives motion from the upper shaft, communicates motion to the lower shaft, and is provided with a crank 17, connected to the slide, as bya connecting-rod 18. The manner in which the upper shaft is driven is not of the essence of my invention, and will not, therefore, be described in detail. The upper, lower, and vertical shafts are shown as provided with bevel-gears 19, by which the motion of one shaft is communi cated to another.

The gist of my invention lies in the mode in which the vertical or crank shaftis mounted-that is, so as to swing Wholly out of the way and permit the slide, no matter how wide it may be, to be removed from the machine without any interference with other parts of the machine. In order to accomplish this result, I mount the vertical shaft in a swinging bracket and provide means for locking the bracket rigidly in place in use. It will of course'be obvious that the special construction or design of this bracket, or the mode in which it is hinged, or the special portion of the framework of the machine to which it is hinged, are matters that may be varied to an almost unlimited extent without departing from the principle of my invention.

20 denotes an abutment which extends outward from the framework of the machine and may be cast integral with some portion thereof or may be rigidly secured thereto.

21 denotes the swinging bracket upon which the vertical shaft is mounted, and which is shown as hinged, as at 22, to abutment 20. This swinging bracket is shown as rigidly locked in the operative position by means of a bolt 23, which passes through the bracket and engages the abutment. The operation of the swinging bracket will be readily understood from Fig. 3, in connection with the other figures of the drawings.

The parts are accurately proportioned and finished, so that when assembled and the bracket is swung into operative position the bevel-gears upon the vertical shaft will mesh accurately with the bevel-gears upon the upper and lower, shafts, as is clearly shown in Fig. 1, in which position the parts are securely and rigidly locked by bolt 23.. Should it be desired at any time to remove the slide for the purpose of changing the carrying-fingers or for any purpose whatever, the connecting-rod is disconnected by removing the pivot-bolt 24, which connects it to the slide, and bolt 23 is disengaged from the bracket. As soon as these bolts have been disengaged from one of the parts retained thereby the bracket, carrying with it the vertical shaft and the crank, may be swung wholly out of the way, as shown by dotted lines in Fig. 3,

in which position of the parts there is no ob-.

struction to the removal of the slide. In the present instance I have shown vertical shaft 16 as stepped in an arm 25, pivoted to the bed, as at 26, and adapted to swing in a plane parallel with bracket 21.

Having thus described my invention, I claim- 1. In a machine of the character described the combination with upper and lower shafts,-

of a vertical shaft, intermeshing connections on said shafts and a swinging bracket by which the vertical shaft is carried.

2. In a machine of the character described the combination with upper and lower shafts and a vertical shaft, said shafts having intermeshing connections, of a swinging bracket upon which the vertical shaft is mounted, areciprocating slide and operating connections intermediate the slide and the vertical shaft.

3. In a machine of the character described the combination with upper and lower shafts and a vertical shaft having a crank, said shafts having intermeshing connections, of an abutment extending from the framework, a bracket hinged to said abutment upon which the vertical shaft is mounted, a reciprocating slide and a connecting-rod intermediate the crank and the slide.
