SPECIFICATION forming part of Letters Patent No. 641,392, dated January 16, 1906. Application filed November 21, 1898. Serial No. 697,061. (No model.)

To LZZ whom, it may concern:

Be it known that I, HORACE INMAN,a citizen of the United States, residing at Amsterdam, in the county of Montgomery and-State of New York, have inventedV certain new and useful Improvements in Staying-Machines, of which the following is a specification.

My invention relates to staying-machines adapted for attaching stays to the corners of boxes and other articles; and it has for its object to improve and simplify such machines and to these ends it consists in the various features of construction and arrangement of parts, substantially as hereinafter more particularly set forth.

Referring to the accompanying drawings, wherein I have illustrated a preferred embodiment of my invention, Figure l is'a side Fig. 2 is an enlarged side view of a portion of the machine, some parts being in section. Fig. 3 is aplan view 0f the parts shown in Fig. 2. Fig. 4.is a front view of the same. Fig. 5 is a vertical sectional View of the same. Fig. 6 is a still further enlarged detail view, partly in section, showing more particularly the cutting apparatus; and Fig. 7 is a side view, partly in section, ofthe parts shown in Fig. 6.

One of the principal objects of my invention is to provide an exceedingly simple, cheap, and effective stay-machine-such, for instance, as can be readily operated by handpower, although, of course, it may be .otherwise operated-and I have set forth -the construction and arrangement of the parts in the machine illustrated in the accompanying drawings as an exemplification of my invention, it being understood, however, that my invention is not limited to the precise details and that these maybe varied in construction and arrangement and used together in the manner shown or in connection with other equivalent devices without departing from the spirit of my invention.

In the drawings, A represents a suitable standard, having a curved head portion A', which is adapted to support the upper stationary, but adjustable, die B, while the lower and movable die C is mounted on a rod D, sliding in a hollow bearing A2 on the frame and shown as connected to be operated by the treadle D through the medium of the connecting-link D2, the frame being preferably recessed on its front side to receive a portion of the treadle and link and they be'- ing so shaped as to form asort of toggle-joint well adapted for raising the rod D and parts carried thereby and producing the desired and necessary pressure. a

The upper die B, which may be of any desired shape, according to the work being done, and shown in the present instance with a V- shaped recess to receive the corners or edges of a box or similar article, is mounted 0n the.

bent head portion A of the standard in any suitable way; but, as shown more particularly in Fig. 5, it is adjustably mounted thereon, being held in position by screws B passing through enlarged openings in the die B, and adjusting-nuts B2 are adapted to assist in holding the die in its proper adjusted position, being provided with set-nuts or other similar devices, as indicated. One edge of this die B, as b, forms a cutting edge coperating with the movable cutter E, the cutting edge e of which is shown as tapering slightly, so as to give a shear cut to the stay material as it is moved to cooperate with the stationary cutter or knife in the manner hereinafter described. This knife or cutter E is mounted on a sliding gate G, being secured thereto in the present instance by screws e', and this gate is arranged to slide vertically with relation to the upper die B in any suitable way, in the present instance it being dovetailed to slide on the edges of the die B, as indicated in Figs. 3, 6, and 7, the vertical movement of the gate being preferablylimitedin some suitable way, as by means of the slot G' therein sliding on a pin B3 on the face of theupper die. The gate G is further provided with some sort of means to allow it to be raised or lowered at proper times and preferably,`as in the present instance, to permit of acertain lost motion of the operating device, so that it will be moved upward and downward at proper periods, and in the present instance l have shown pins G2 G3 on the face of the gate, between which pins plays the operating device hereinafter described. Also attached to the gate G is a guide-plate G4, arranged above the knife and forming a passage-way for the staystrip.

The stay-strip feeding and pasting or dampthe standard, and while any desired form of pasting or damping device may be used I have shown in the present instance a damping device to be used in connection with adhesive stay-strips and comprising, essentially, aliquid-containingboxhaving extending over its upper surface an arm H2, on which are adj ustably mounted the guides h h for the strip, and provided also with the feeding and damping rolls H3 and H4, mounted in bearings extending u pward from the sides of the box. The upper feeding-roll H3is preferably grooved on its face, as best shown in Fig. 2, and is provided with a spur-gear h3, engaging a similar spur-gear h4 on the damping-roll H4. This latter dam ping-roll is also preferably provided with a spiral groove on its surface, in which is placed an absorbing cord or thread h2, operating in a wellknown manner, and this -roll is further mounted on an eccentric shaft H5, having adjusting thumb-nuts h5 for securing the shaft in position after it has been adjust ed in the proper relation to its companion feeding-roll H3, according to the thickness of the stay-strip. It will be seen that by turning the eccentric shaft I-I5 the feeding and damping roll H4, mounted thereon, will be adjusted in proper relation to the companion feeding-roll H3. These feeding-rolls are operated at proper intervals by suitable mechanism, and I have shown in the present instance a ratchet-wheel H6 on the end of the shaft of the feeding-roll H3, having four ratchet-teeth h", they being shown in the form of notches, with which a suitable pawl engages at the proper time, as hereinafter described.

Mounted to rock loosely on the rod H' is a sleeve I, carrying an arm I', to which is pivotally connected a link I2, the other end of which is connected to a rocking arm I3, carrying a pawl I4, adapted to engage the notches of the ratchet-wheel H6, and while this is a convenient means for intermittently operating the feeding and damping rolls any other equivalent connections may be used. Connected to the sleeve I is an arm I5, preferably having a friction-roller I6 on its end adapted to come in contact with a portion of the movable die carrier or rod D, by means of which the sleeve is rocked, as indicated in Fig. 6, and a spring J or equivalent device is connected to apin A4, extending from the standard at one end and at the other end to the arm I5 to restore the sleeve I and its connected mechanism to their normal positions when the movable die-carrying rod returns to its normal position.

The die-carrying rod D in the present instance is shown as enlarged at its upper portion D8 and as having a lateral extension or anvil D4 for supporting the lower die C, and this die is mounted on the anvil D4, so as to have a sufficient lateral movement to insure its proper cooperation with the upper die,

and in the present instance the anvil D4 is provided with a projection d4, while the die C is recessed at c, into which recess the projection d4 extends, allowing free play on either side, so that the lower die C can move to a greater or less extent laterally. Connected to the projection d4 is a plate D5, mounted on rods d5, which can be drawn in or out of the projection d4, as indicated in Fig. 7, to aid in supporting the box or other article being operated on.

Mounted on the die-moving rod D and preferably on the enlarged portion D? thereof is a bent arm K, the free end K' of which plays between the pins G2 G3 on the gate G, and it will be readily seen that when the movable die is moved upward the arm K also moves upward, and the portion K' thereof coming in contact with the pin G2 the gate will be moved upward at the proper time, and when the arm K is moved downward the portion K' will come in contact with the pin G3, forcing the gate downward if it has not already fallen by gravity. As the rod moves upward, a cam L comes in contact with the roll I6 on the arm I5, operating sleeve I to feed the stay-strip.

The stay-strip may be conveniently mounted on a reel M, supported on an arm M', secured to the standard; but any other support for the source of supply of the stay-strip may be used.

From the above description of the machine shown in the drawings its operation will be IOO readily understood and may be brieiiy stated as follows: The stay-strip passes from the reel M, between the guides h h on the arm H2, between the rolls H3 H4, where paste is applied, or if an adhesive strip is used the adhesive material moistened by passing over the moistening-roll H4, the two rolls operating as a feed. The end of the strip passes over the knife E, beneath theguide G4, and the parts lare now in condition for operation. The parts to be united-as, for instance, the edges of the sides of a paper box-are placed over the die C, and the box may be supported by the plate D5, and is held in the position in which the edges are to be united by the operator. The treadle D is then operated and the lower die moved upward, carrying the box against the stationary die B. As the anvil and rod D move upward, the cam L, through the medium of the arm I5, operates the sleeve I and through its connecting mechanism operates the feedrolls H3 H4 to feed the stay-strip a proper distance under the upper die. As the lower die proceeds in its movement the movable knife remains stationary owing to the lost motion of the bent arm `K and extension K between the pins G2 G3; but when the lower die reaches the proper position the extension K' strikes the pin G2, raising the gate G and severing the stay-strip between the movable knife E and the knife-edge b of the stationary die B. At this moment the movable die C, with the parts to be united, reaches the staystrip and bends it into the stationary die and IIO able die, and a pawl-and-ratchet mechanism connected to the sleeve and operating the feeding and damping rolls, substantially as described.

13. In a staying-machine, the combination with the stationary and movable dies, of a feeding and dampingdevice, a movable cut-- ter mounted on the stationary die and arranged between the feeding and damping device and the stationary die, and means connected with the movable die to operate the feeding and damping device at the beginning of the movement of the movable lower die toward the stationary upper die and the cutter near the end of such movement, substantially as described.

14. In a staying-machine, the combination with the stationary and movable dies, of a stationary feeding and damping device, a mov'-y able cutter arranged between the feeding and damping device and stationary die, a gate supporting said cutter and having a guide for the stay-strip, and connections between the cutter and feeding and damping rolls and movable die whereby the feeding and damp ving rolls are operated at the beginning of the movement of the die and the movable cutter near the end of the upward movement of the die, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of a further movement presses it onto the parts to be united. As before intimated, the movable die C is capable of a slight lateral movement, so that equal pressure will be given to all parts of the stay-strip.

It will be noticed that the arrangement of the treadle connections is such that the lower die moves rapidly at the first movement of the treadle and more slowly toward the latter` movement, but with greater compressing power, so that the stay is easily and at the same time firmly attached to the parts to be united. On releasing the treadle the parts assume their normal position, and as the extension K moves away from the pin Gv2 there is a certain lost motion; but before the lower die reaches its normal position the extension K' impinges on the pin G3, insuring the gates movement ready for another operation. The spring .I aids in restoring the parts to position when necessary.

It will be seen that the abovedescribed construction is exceedingly simple, compact, and it has proved very efiicient. It has been found exceedingly advantageous to have the upper die adjustable, but stationary,and to move the lower die, carrying the article to be operated upon, upward against the stationary die, and it will further be seen that the stay-strip is fed forward at the beginning of the upward movement of the lower die, and the gate carrying the cutter is operated during the latter part of the movement of the lower die after it has reached aposition to impinge upon and hold the stay in the position desired as it is severed from the strip, and there is no liability of its slipping or getting out of place. The arrangement of the treadle and connections is such that any requisite or desired pressure may be given to the parts and the machine can be rapidly operated and is not liable to get out of order.

What I claim is- 1. In a staying-machine, the combination with a stationary upper die, of a movable lower die, a staystrip-feeding device, connections between the same and the movable die wherebythe feeding device is operated at the beginning of the movement of the movable die, a stay-cutting device, and connections for operating the same having a lost motion so that the cutting device will be operated as the movable die reaches nearly its final upward movement, substantially as described.
