PINTLE-INSERTING IMACHINE.

original application filed July 29, 1919, Serial No. 314,013. Divided and this application filed June 22,

To all whom it may concern:

Be it known that I, CHARLES V. Srrnon- LAND, a citizen of the United States, and resident of lVinston-Salem, in the county of 6 Fors'yth and State of North Carolina, have invented certain new and useful Improvements in Pintle-Inserting Machines, of which the following is a specification.

My invention'relates to a hinge forming 10 machine, and especially to a machine for attaching hinge pintles to sheet metal blanks.

It is particularly applicable to machines of the type. shown in the United States patent to Richter, No. 1,096,863 issued May 19, 1914, the invention set forth in this specification being a division of that disclosed in my copending application Ser. No. 314,013, filed July 29, 1919, 1,413,627 dated April 25, 1922.

Machines of this general nature handle a sheet metal blank, which may either be flat or formed into any other shape, the preferred type operating on flat blanks. The blanks are provided with suitable projecting elements, which the machine wraps about a wire pintle automatically out off and brought into engagement with the blank elements. By this operation the pintle is permanently mounted on the blank with spaces between the blank elements where the pintle may be engaged by the similar elements of the other hinge member.

Machines of this type have heretofore been operated as separate units, the pintled blanks being discharged by the machine into any suitable receptacle and delivered to the operator of the machine which forms the blanks into metal container bodies.

A principal object of my invention is to provide a. pintle inserting machine which will deliver its product directly to the body forming machine. A corollary object is to provide means for insuring the accurate registration of the delivered blanks in proper position on the body forming machine to be engaged by the operating mechanism of the latter.

Another object is-to so arrange and construct the parts of a pintle inserting machine of the type indicated that it can read ily be actuated by the driving mechanism now Patent No,

Serial No. 479,585

of the body forming machine, and preferably so that the pintle forming machine is mounted on the body former substantially as an attachment thereto, with the obvious resultant saving in floor space, construction expense and operating difiiculty.

Other objects and advantages of my invention will be apparent from the following description, taken in connection'with the accompanying drawings, in which:

The single figure is a front elevation of the entire machine mounted on a standard type of body forming machine, parts being broken away.

The form of pintle inserting machine disclosed in the preferred form illustrated is described in detail in my above mentioned Patent No. 1,413,627, and is of the general type shown in the Richter patent. As my present invention relates to the combination of this machine with the body former, I will set forth merely the important features of the pintle inserting mechanism, reference being made to my abovementioned patent and the Richter patent for a detailed description of the parts.

The fiat metal blanks 25, preferably lithographed, are fed into the machine by hand. a stack of blanks being shown on the plat form 42 at the left of the machine. They are placed by the operator on a reciprocating feed plate or bar provided with spaced feed dogs 48 which are spring pressed upwardly the outer end of each dog projecting slightly above the upper surface of the feed bar and engaging the rear edge of a blank and advancing it during the forward stroke. of the feed bar from left to right. On the return of the feed bar the blanks are held in stationary position by various friction devices, the dogs 48 sliding under the blanks. The feed bar is reciprocated by a rock arm 36 pivoted on the frame and connected to the feed bar by a link 35, arm 86 being oscillated by pitman 37.

While in stationary position, the edges of the blanks are first cut to shape by the cutter 61, and then provided with pintles attached thereto by a pintle inserting mechanism, the main operative portion of which is indicated at 66, this portion being adapted to engage tongues on successive blanks with wire pintles. The cutter 61 and pintle applying mechanism 66 are mounted on a vertical reciprocating ram 50 connected to a crank on shaft 54, so that a blank is cut away and the successive blank provided with a pintle at each descent of ram 50, while the blanks are held in stationary position during the return of feed bar 33.

The machine is also provided with a device, indicated generally at 100 which is arranged to feed forward intermittently a continuous wire to provide suitable pintle lengths, one of which is cut off and engaged by the pintle forming element 66 at each descent of the ram 50. The wire feeding device 100 is operated by a pitman 93.

The body forming machine includes a frame 23 carrying a drive shaft 42, and provided with a guideway or channel 1.2 1 along which the pintled blanks are advanced by suitable mechanism into engagement with the devices which form therefrom container bodies.

1 have so constructed and arranged the pintle inserting machine that it will deliver blanks to the feed channel 12% of the body former in proper position for operation thereby. I have accomplished this result by locating the pintle inserting machine in po sition so that the feed bar 33 extends substantially at right angles to the feed channel 124i and into juxtaposition thereto, so that the last feeding movement to the right i1 parted to a blank by the feed bar will locate it with considerable accuracy across channel 124. With the type of body former now in general use and illustrated in the drawing, the blank will be positioned properly for engagement by the operating mechanism of the body former.

I may also provide suitable mechanism for insuring the accurate registration of the blanks on the body machine feed, so that the carriage of the latter will engage them without any manipulation by the operator. This mechanism may consist of a lever 119 pivoted on a bracket 120 mounted on the bed of the body former, one end of the lever carrying a roll 121 engaging cam slot 122 in cam 123. The opposite end of lever 119 carries positioning plate 124 mounted adjacent to the end of the pintle machine feed and shaped to guide and hold the pintled blank in accurate position on the feedway of the body machine. It will be noted that the positioning plate 124 is so contoured and particularly is recessed at its lower face, so as to clear the carriage of the body former which travels along the feedway 124 conveying the successive pintled blanks into the body forming mechanism.

I also provide means whereby the operation of the pintling machine and that of the means for registering the blanks on the body former are synchronously operated. In general I accomplish this object by providing direct connection between the driving mechanism of the pintling machine and that of the registering device. In the form shown, I have also provided a simple driving construction for all of the parts indicated, which further assures complete synchronism between the pintling machine and the body former. I have accomplished this object by driving all of such devices from a vertical shaft 10 suitably driven from the shaft l2 of the body former. Pitman 87, which operates the feed bar, is actuated by cam 39; pitman 93 operating the wire feed is actuated by cam 97; and both of said cams, together with cam 123 which operates the blank registering device, are directly mounted on shaft 40. The latter shaft also drives, by suitable gear connection, shaft 54 which operates the blank cutting and pintle attaching devices. Obviously various other driving arrangements may be employed, the one illustrated being primarily advantageous because of its simplicity and convenient arrangement.

The operation of the machine is as follows. As heretofore indicated, successive blanks 25 are located on the left-hand end of feed bar 33, which shifts the successive blanks step by step toward the right, the blanks being excised when under the cutter 61, and provided with pintles when under the pintling device 66. From the latter station they are advanced step by step until the final impulse from feed bar 33 projects them into position across the feed channel 12 i of the body former. During the latter motion the registering plate 124- is maintained in elevated position by cam 124; but as soon as the blank is located on the body former channel the registering plate 124i is depressed, positioning the blank accurately on said channel and preferably maintaining it in such position until the body former carriage has engaged the blank and advanced it along the channel. The registering plate 12a is then elevated to receive the next blank, the feed of the pintle inserting machine being suitably synchronized. with that of the body former, as by driving connections of the type indicated.

It will be apparent that substantial modiiications and changes may he made in the various elements, and particularly in the type of mechanism employed for inserting pintles in the blanks and for feeding them forward. My invention therefore is not limited to the particular arrangement shown, but may be substantially varied as indicated b j the scope of the following claims.
