PAPER-FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 767,444, dated August 16, 1904.

Application filed October 1,1902. Serial No. 125,458. (No model.)

Tr) all lull/rmt t Nte/,y concern:

Be it known that I, THURBUR F. RUSSELL, of Newton, county of Middlesex, and State of Massachusetts, have invented an Improvement in Paper-hhstening Devices, of which the following' description,'in connection with the accompanying' drawings, is a specification, like letters on the drawings representing' like parts.

The present invention relates to a paperfastening device, and is embodied in a machine for fastening together sheets of paper and the like, the object of the invention being' to obtain an efficient and durable machine for this purpose which is simple in construction and easily operated. The machine embodying the invention is so arranged that two movements of an actuating device will result in punching the sheets of paper to be fastened and subsequently inserting' in the punched opening' a suitable fastening device, the machine being especially adapted to be used with eyelets of the kind commonly employed in shoe-uppers and frequently used for fastening' papers. The machine is entirely automatic in its operation, comprising' a support for the papers to be fastened, a punch and setting device, an automatic feed for the fasteners, and a single actuator adapted to cause the machine to perform the complete operation of punching the papers and feeding and setting' the fastening device.

The invention is herein shown as embodied in a machine adapted to utilize eyelets for fastening devices, and comprises a punchingdie and its cooperating member and a setting device and its cooperating member, both of which are mounted on a reciprocating carriage which is adapted to move back and forth relatively to a stationary support for the papers.

The punch and setting device are provided with a common actuating member adapted by its movement in one direction to cause the operation of the punch and by its movement in the opposite direction to cause the operation of the setting' device, the said actuating member being also connected with the carrier for the punch and setting device, so as to move the said carrier between the successive operations of the punch and setting' device to remove the punch from its operating position and to bring the setting device to the same position, so as to be in alinement with the hole or perforation made in the papers by the punch. Cooperating with the setting device is a feed member to supply fastening devices to the setting device, so that at the time when said setting' device is moved to its operative position it has already been supplied with a fastening device to be set in the previously-punched hole in the papers. As herein shown, the lower member of the setting device is provided with a pin or support Which is arranged to be held Hush with the lower setting member during the movement of said member toward a suitable feed-chute, which is supplied with eyelets and which has at its lower end a yielding stop for the eyelets, the said pin being arranged to move upward and engage an eyelet at the time when said lower member is below the chute. eating' movement of the carrier for the punch and setting device after the hole has been punched in the papers the eyelet is carried along upon the pin, so as to be presented to the punched opening, and in the setting operation the pin is depressed and retained in its depressed position until it again reaches the chute ready to pick up an eyelet.

The machine is further provided with a retaining device to hold the papers in position during' the punching and setting operation, the said retaining' device being so arranged as to move into contact with the papers in response to the first movement of the actuating device which produces the punching operation and to remain in engagement with the papers during' the subsequent operation of the machine, being nally released after the papers have been fastened.

Figure l is a side elevation of a machine embodying' the invention; Fig. '2, a partial front elevation of the same, partly in section; Fig. 3, a transverse vertical section; Fig'. 4, a partial underneath plan view. Fig. 5 is a longitudinal section showing' the parts of the machine during the punching' operation, and Fig. 6 is a similar View showing the parts of the machine at the end of the setting operation.

Referring to Fig. 5, the punch L and upper In the recipro- IOO setting' device /1 are mounted so as to be long'itudinally movable in a reciprocating' carriag'e c, which is adapted to slide upon the bed or frame A of the machine, the said carriage having' wings rfi, Figs. 2 and 3, which are held in position by means of plates A2, which are secured to the frame so as to overlie the said wings and to afford lateral g'uides for a portion of the carriage above the said wings.

'lhe punch /r is shown as a plung'er litting' a vertical opening' in the carriage c and having' a shoulder H2, between which and the bottom of the opening' is interposed a spring' at, which tends to hold the punch in the position shownin Figs. l and 6. 'lhe said punch is provided with a cutting-die f/X, which is adapted to enter a corresponding' female die fr," in the body portion of the carriage c, so that when the said punch L is depressed with sheets of paper between it and the die a" it will punch a hole Vfor the reception of a suitable lastening' device. The setting-die is also arranged to cooperate with a corresponding' member f, which supports the rim of the eyelet while the shank is beingl` crushed into engagement with the papers to be fastened. ',lhe carriage c is arranged to be reciprocated through the action of a lever (Z, which is pivotally supported at Z2 and provided with a slot d, which engages a pin or projection c from the carriage c, so that when the said lever /Z is swung' upon its pivot (Z2 it will cause the carriage c to move back and forth along' the Vframe A, upon which it is supiiorted. The said lever (Z is shown as arranged to be actuated by means of a cam-groove e, formed in a member e, which is shown as a plate snitably secured upon an oscillating shaft f, to which is also secured the actuating-handle g. The same actuating-handle is arranged to cooperate also with the punch a and the upper setting' device 7) and has a considerable range of movement, the camgroove a, therefore, being' shaped so as to produce no movement of the cam-roll (Z1 and the lever (Z during' a greater partof its throw, the said movement taking' place at about the middle of the complete movement of the handle y, as shown in the drawings.

Starting, for example, from the position shown in Fig'. l and moving' the actuator f/ to the position shown in Fig'. 5, the cam-roll (Z will remain in the portion e of the cam-groove cut in the member a2, the said portion being' curved on an arc struck Afrom the center of movement of said member 7, so that no movement of the lreciprocating' carriage c will take place during' this movement of the actuator (j. The carriage c is thus held in the position shown in Fig. 5, in which the punch members and n are in position to punch a hole in the paper, and during' this time the punching member r/ is acted upon by a cam ,r/g, formed on the actuating' member g, the said cam bearing' directly upon the top Of the punch (t, s0

as to force the same downward and punch the paper. The actuator r/ is then turned in the opposite direction, and the punch (l, being' released by the cam (y2, rises through the action of the spring' fr, the cam-roll d' reaching' the portion c" of the cam-groove in the member a at about the time when the punch has reached its normal position. The action of the cam-groove at this period in the operation is to swing' the lever Z upon its pivot (Z2 and move the carriage c to the left, thus bringii'ig' the setting' members L and b2 into the position previously occupied by the liunching' members, so that they are in alinement with the hole made by the punch, the papers nothaving'been moved in the meanwhile. A continued movement of'the actuating' member y] to the rig'ht as indicated in Fig. 6 will produce no further movement of the carriage c, since the portion e of the cam-groove e is also curved on an arc struck from the center of oscillation of the supporting'memberf Such movement, however,is communicated to the upper setting' member throug'h the agency of a link 7;, which is pivotally connected at 7)" to the upper end of the setting' member the said link b being' operated upon in turn by a pin g3, which enters a slot f in the link eng'ag'ing' the bottom of said slot and depressing' the link and setting' device 7) as the actuating` member f/ is pushed over to the position shown in Fig'. 6. The lower setting' device L2 having' been previously provided with a fastening' device, such as an eyelet, thus presents the eyelet to the opening' and the eyelet is clenched, as shown in Fig. 6. Upon restoring' the handle 0 to its intermediate position the setting' devices are separated from each other and the papers, properly fastened, may be removed.

In order to supply the lower setting` device t2 with the fastening` devices, the machine is shown as provided with a feed-chute L, leading from a suitable hopper 7L, which is adapted to contain a mass of eyelets, which travel down the chute, the lowermost eyelet being' held in the end of the chute by means of the ordinary spring-gate or yielding' member, which prevents the eyelet from falling' from the chute through its own gravity, but permits the eyelet to be pulled from the chute if Y extraneousl f eneao'ed. To engage and feed the u b D lowermost eyelet, the lower setting' device 7X5 is shown as provided with a depressible ling'er L, which is normally pressed upward. by means of a spring' 7)?, but arranged to be eng'ag'ed by a suitable retaining' device after it has been depressed during' the operation of setting' the eyelet.

As herein shown, the linger 7) is provided at its lower end with a tapered projection lf, above which is a shoulder 7;", the said tapered projection being' arranged to engage a slot which is formed between two separable members 7u, secured to the under side of the frame TOO VlIO

A by means of screws 7a2 and normally held together by means of springs said members, however, having slots 1* (dotted lines, Fig. 4) whereby they may-be moved laterally to separate them. T he said members are eut to form a slot between them substantially equal in width to the diameter of the finger 71", but smalier than the diameter of the shoulder 7;", so that when the said linger is forced downward by the upper set, as shown in Figs. 3, 4, and 6, the tapered member bs will push through, separating the members 1, which will spring together after the shoulder 7) has passed below the said members r, which members then constitute a retaining device to prevent the upward movement of the fing'er. The slot for the said linger 7) extends along the members in the direction of movement of the carriage c, and at the point where the said linger reaches the feed-chute /t the said slot is widened so as to afford space suihcient to permit the passage of the shoulder 69, thus permitting the upward movement of the finger b in response to the action of the spring ,717. The finger L then being below the end of the chute z, it is obvious that the finger will enter an eyelet in said -chute and engage the same, so that'it will carry away the said eyelet during the next reciprocating movement of the carriage c, properly presenting the same to the upper setting device 7), which is then in the position to complete the setting operation.

During the fastening operation the paper is supported upon a table m, which is shown as a frame having' a large middle opening for the operation of the fastening devices, the said table being supported upon the frame A by means of studs m2 at opposite sides of the machine. The paper is held in position by means of a retaining device, which is shown as mounted on a rock-shaft n, having bearings n2 upon the table m, the said rock-shaft being provided with a spiral spring 11,3, the tendency of which iste hold the same in the position shown in Fig. l. The paper is retained in position by means of spring-fingers w", connected with the said rock-shaft 71y and arranged to be moved toward the surface of the table m, so as to hold the paper thereon. rlhese lingers normally stand away from the table, as shown in Fig. l, and the carriage c is also provided with a guide member c4, which, in conjunction with the table mi, tends to hold the loose sheets of paper together until the said sheets are engaged by the fingers 01.*. The said fingers are arranged to be pressed downward upon the surface of the papers during the lirst movement of the actuating-handle g, which produces the operation of the punch a, this being accomplished by means of an actuating member o, shown as pivotally supported upon the side of the carriage c and arranged to be acted upon by a cam-surface e, formed on the member e2, and in turn to act upon a radially-projecting member a5, secured to the rock-shaft a. This cam 0 normally stands in the position shown in Fig. l, being limited in its movement by a stop 02,- but in the first movement of the actuating member g to the left the said cam is engaged by a projection e7, formed on the cam-surface e, which turns it toward the right, causing it to act upon the arm a5 and force the fingers n* down toward the paper supported upon the table m. The member o will remain in this position during the subsequent operations of punching the paper and shifting the carriage, but will be restored to its normal position during the setting operation, in which the cam-surface e strikes the member 0 and moves it back into its normal position.
