RIVET AND BUTTON ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 450,828, dated April 21, 1891.

Application filed May 24, 1890. Serial No. 353,032. (No model.)

To all whom it may concern:

Be it known that we, IRVING G. PLATT and FRANK R. WHITE, citizens of the United States, and residents of W'aterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Rivet and Button Attaching Machines, of which the following is a specification.

IO Our invention relates to an improvement in rivet and button attaching machines, the object of the same being to improve upon the construction and arrangement of the fastening devices as now constructed and employed in machines of this character, and to provide devices for this purpose which will be more certain in their operation of attaching the buttons than has heretofore been the case.

A further object of our invention is to pro- Vide a machine of this character which shall be simple in its construction and arrangement of parts, which shall be easily and readily operated and understood by unskilled persons, and which will at every operation of 5 the machine attach the button and rivet with certainty, which will not be liable to easily get out of order, and so constructed and arranged that the several parts of the attaching mechanism may be readily and nicely ad- 3 justed. \Vith such ends in View ourinvention consists in certain novel features of construction and combination of parts, as willbe hereinafter fully described, and set out in the appended claims.

In the accompanying drawings, Figure I is a view in side elevation of a portion of abutton-maehine having attached thereto our improved fastening mechanism. Fig. II is a longitudinal sectional view thereof on the line a; m of Fig. III. Fig. III is a horizontal sectional view taken on the line y y of Fig. II.

Fig. IV is a similar view showing the parts in their adjustment after the plunger has been depressed. Fig. V is a horizontal sectional view on the lines .2 of Fig. II. Fig. VI is a front sectional view taken on the line ,2 z of Fig. III. Fig. VII is a similar View after the plunger has been partly depressed or lowered. Fig. VIII is asimilar View showing the parts in their several adjustments after the plunger has been lowered. Fig. IX 1s a detail View of the cam employed to open or Separate the receiving-jaws.

0 ur in vention, as will be hereinafter learned, belongs to that class of devices for attaching buttons and rivets contemplating the use of a rotatinghopperA,intowhichtherivetsortacks are fed in bulk, and from which they are led to the attaching device by means of a twisted chute B, into which they are fed point up and head down, and from which they escape into the receiving-jaws head up and point down, and which class of machines also contemplates the use or employment of mechanism for revolving said hopper and the ordinary form or construction of cut-off B. The ma chine is also provided with a main frame A, consisting of a curved supporting-arm a and the base or bed plate Z), to which supportingarm a is attached the 0perating-leverA and which in turn has connected therewith the vertically-reciprocating plunger A working or sliding in the barrel or cylinder a, formed on the supporting-arm a of the main frame.

As those parts of the machine above referred to are of the ordinary construction and arranged to operate in a manner which is well understood by those skilled in this art, it is not deemed necessary to describe in detail their construction or arrangement.

The curved arm a of the frame is provided with the bifurcated arm 00*, between the prongs of which fits the twisted chute B, which is held thereby against all lateral movement, but which arm allows of a downward and backward movement of the chute in case a rivet or tack should accidentally become wedged between the plunger and the chute.

'As shown by Figs. 3 and l of the drawings, the lower rear portion of the curved arm a of the frame is provided with an elongated slot or opening to, in which is mounted or pivot-ed one end of the arm 0, the forward end of which is flattened or widened into the form of a plate, as shown at d, the object or purpose being to form or provide a support for the attachment of the rivet-receiver, which consists of the two arms (1, having their rear ends attached to said plate or support (I by the common pivot d and connected and retained in their proper position by means of the spring E. The ends of the said two arms d are extended to a point directly below the plunger A and cup-shaped in form, as shown at d for the purpose of receiving a rivet or tack from the lower'end of the twisted chute or raceway leading directly thereinto and holding said tack in position to be operated,

upon by the plunger when the latter is lowered.

To the plate (Z and between the arms (1 of the receiver is secured by means of a screw 6' the sleeve or cam F, fitting around said screw e and having its sides flattened, as shown at 6 against which flattened sides bear the inner sides of said arms (1 when the latter are in their closed position for receiving a rivet from the raceway. This cam is formed on its upper end and at one side with ahandle 6 by which it may be turned upon the pin or axis e, the object and effect of which is to open or separate the arms d and cup (1 and release or allow the escape of the rivet or tack therefrom when desired to remove it, the spring E returning the arms 01 to their normal position upon releasing the handle 6 of the cam.

The arm 0, with its attached spring-actuated receiver, is supported in its normal or substantially horizontal position (in which po sition the cup or receiver 62 is held up against the lower end of the raceway or chute B) by means of the rod or bar f, which passes through said arm 0 and threaded therein, and is secured in its several vertical adjustments by means of the lock-nut f, the lower end of said pin, which projects below the arm 0, resting upon the head or upper end of the plug f which is nicely fitted within the cylinder or barrel f formed on and projecting above the bed-plate b, said plug resting or being seated upon a coil-spring f titted in the cylinderf the object of this construction and arrangement of parts being to allow a downward or vertical movement of the arm (3 and its attached receiver, and upon the release of the said arm to return the latter to its original horizontal position, the arm, after having been raised to its proper height by means of said spring, striking or abutting against the set-screw g, threaded in a receptacle or sleeve 9 formed on and projecting downwardly from the supporting-arm a, said set-screw, after being raised or lowered to its proper adjustment to determine the proper height to which the said arm 0 is to be raised, being locked in such adjustment by means of the lock-nutg It will of course be understood that by raising or lowering the pin or barf and the set-screw g the arm 0 will be correspondingly raised or lowered and the extent of its vertical movement or travel correspondingly limited or enlarged. It is obvious that, if desired, the arm 0, with its receiving-jaws, may be held stationary, the arm having been first so adjusted that the point of the tack or rivet will enter the goods before being entirely forced out of the receiving-jaws d d by the plunger.

In the slot 00, formed in the lower rear end of the supporting-arm a of the frame and below the pivotal connection of the arm 0. is

pivotally secured a lower or second horizontal arm 0', which is widened and flattened at its forward end to form a support or base It for the plates h h, each of which latter is pivoted at its rear end, as shown at 71?, to the arm 0, and are held in their proper relative position by means of a spring g the forward ends of said plates being arranged to separate and extend out beyond the forward end of the arm 0 and below the cup (1 formed on the forward ends of the arms 61', secured to the arm 0.

The spring-actuated plates h h are provided with the opening g in their forward ends to permit. of the entrance of the tack, as hereinafter described, the sides of said opening beingpreferably beveled for the purpose of properly guiding the point of the tack through the said opening, and is formed in the same vertical line with the opening in the cup 01 The arm 0' is also widened near its rear end in order to provide sufficient material to allow the opening 71 to be formed therein, the latter intended and serving as an opening or passage for the post f and plug f to permit of their vertical movements withoutinterfering with the movement ofthe arm 0. The rear ends of the said yielding plates are cut away at a slant, as shown at h, for the purpose of allowing their free forward ends to be separated or spread apart, said rear ends of the plates striking or impinging against. the fin or flange 9 formed on the upper side of the arm 0' after the forward ends of said pivoted plates h 72/ have been separated to their fullest extent.

The arm 0' is held in its normal or substantially horizontal position by means of the sliding rod or bolt 1'', on the upper end 2' of which said arm rests, and which end is also provided with a head or flange 2' against which fits the upper end of the coiled spring '5 the lower end of said spring impinging against a shoulder formed around the opening i made in the base-plate b,- and in which opening reciprocates the rod i, the lower end of said latter rod extending out through said opening and provided with a thread on which is fitted the nutj. It will be understood from this construction and arrangement of parts that after the arm 0 with its attached spring-actuated plates has been lowered by means of the plunger and released, as hereinafter described, the coiled spring '0'" will return the rod 2" and arm 0 to their original position, the height to which said arm is raised .being regulated by means of the nut j, by raising which the rod will be virtually shortened, and by lowering which the rod will be lengthened, and the height to which said arm 0 is raised being correspondingly regulated.

To the forward end of the base-plate b is attached the yielding button-support 7c, constructed and arranged as followsz-The forward end of said base-platebis provided with a threaded opening 76, in which is fitted the thumb-screw 7%, having tightly secured thereto the anvil 76 The upper end of the thumbscrew k projects through and above the baseplate I), and has fitted thereon the circular nut 71: provided With a shoulder against which fits one end of thecoiled spring 7c, the upper end of the same fitting against the under side of the button-support 7c, the hollow shank of which fits down within the hollow nut and around the die or anvil 753, the shoulders 41/11: being formed on the nut and shank of the support, for the purpose of preventing the parts from becoming separated or disengaged. It will now be understood that when the support 7; is pressed downwardly by means of the plates h h, the upper end of the anvil or die 712 is exposed, and when released will be raised or returned to its original position by means of the coiled spring 7t, the height of said anvil or die it being regulated by raising or lowering the thumb-screw 79.

On the lower side and near the forward ends of the plates 7t h are formed the downwardly-projecting lugs or shoulders Z Z, the inner sides or edges of which are beveled, as shown at Z, and which, when the arm 0 with its plates are lowered, strike against the up per beveled edge Z of the button-support 7c, the effect of which is, when the plunger is forced downwardly, to open and separate said plates and force the latter down upon the upper side of said support 7e, and, the plunger being continued downwardly, to carry said plates downwardly, and, by reason of their bearing upon the button-support, to carry the latter downwardly until the upper end of the anvil or die if is exposed, as before described, the plates It It being returned to their original position by means of the spring after the plunger is raised, the arm 0 at the same time being returned or raised, with the attached plates, by means of the coiled spring To the under side of the arm 0' is secured by means of the thumb-screw Z the adjustable gage Z having its forward end widened in order to allow of the separation of the plates h h, and provided with flaring lugs Z said gage being provided on its under side with an elongated slot for the purpose of allowing said gage to be moved forwardly or backwardly in order to regulate the extent to which the fabric is inserted in the machine, and thereby enabling the buttons to be placed in their proper positions.

Having now fully described the construction and arrangement of the several parts of my improved machine, I will proceed to describe the modus opemmli. Asis well understood, the chute and the cut-off arrangement allow a tack or rivet to drop or fall into the receivers d. The gage having been properly set and a button having been placed in position upon the support 7c, the fabric is placed upon the plates 7L h. The plunger is then forced downwardly upon the head of the rivet, which, with the arm C with its attached recelver, is carried downwardly by the plunger until the lower end of the plug f 3 strikes the bottom of the cylinder f at which time said arm 0 and its receiver have reached the lower arm 0' and the point of the tack or rivet entered, or about to enter, the fabric placed thereon. The plunger being continued downwardly, the jaws d are forced open and the rivet forced out of the cup or receiver (Z into and through the fabric, said jaws partially encircling the plunger and being returned with the arm 0 to their horizontal adjustment by means of the spring. The plunger, being still continued or forced downwardly and bearing upon the head of the rivet, carries the latter, with the plates h h and the arm C and the fabric placed on said plates h h downwardly until the beveled lugs Z Z strike against the upper beveled edge Z of the button-support 70, at which time the said plates will open or separate, as before described, and the several parts then be carried downwardly by the plunger until the point of the rivet has passed through the fabric into the opening in the center of the button and has been upset by striking on the die, the lower end of the plunger being recessed, as shown at :0 for containing the head of the rivet, which materially assists in holding the rivet in its vertical position and causing it to properly en ter the opening in the button and button-sup port. The plunger is then allowed to rise, and the fabric with the button secured re moved from the yielding plates 7t 72/ and the parts allowed to return to their normal position by means of the several springs, as hereinbefore described. The operation. may then be repeated.

What we claim is 1.
