MACHINE FOR WIRING BLIND-RODS.

Y Specification of Letters Patent No. 18,080, dated September 1, 1857.

To aZZ whom t may concern,

Be it known that I, BYRON BOARDMAN, of Norwich, in the county of New London and State of Connect-icut, have invented a new and Improved Machine for Wiring Blind-v Rods; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the anneXed drawings, making a part of this specication, in which- Figure 1, is a side view of my improvement. Fig. 2, is a front view of ditto, the staple feeding device being bisected as indicated by the line (y) (y) Fig. l. Fig. 3, is a vertical section of ditto, taken in the line Fig. 2. Fig.- 4, is a detached lfront view of the guides between which the staples are driven in'to the rods. Fig. 5, is a detached view of one of the rods by which the guides are adjusted.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in the employment or use of two feeding devices, one of which -feeds the staples between the guides which y of which is plainly shown in the drawings,

and B represents a bent or V-shaped lever which is pivoted in the frame A as shown at (a). A foot strap C is attached to the end of the lower bar (b) of the lever B against which bar a spring (c) bears, said spring having a tendency to keep the outer ends of the lever thrown upward as far as they are allowed to be elevated. This culminating point is determined by the lower bar (b), the outer end of which is fitted and works in a slot (d) in the front upright (e) of the frame A as shown plainly in Figs. 2 and 3.

The outer end of the upper bar (f) of the lever B works in a slot made in an inclined bar (g) which is at the end of an inclined bar (71.), the bar (h) being connected with the back upright (i) of the frame A. The lower end of bar (g) is connected to the upper end of upright (c) as plainly shown in Fig. 3. From the inclined bar (g) a lateral or horizontal bar projects. This bar is grooved and a slide D is fitted therein, said slide being secured at any desired point in the bar by means of avscrew (c) which passes into the end of the bar and a screw (Z) which is attached to they slide and passes through the slot in the bar and has a thumb nut on its end. To the outer side of the slide D a spring (n) is attached. This spring bears against a lever E which is attached to the slide by a fulcrum pin (o). The spring (fn.) has a tendency to keep the lower end ofthe lever E against the lower part of the face of the horizontal bar (j) as shown at (ax) in Fig. 1.

To the upper end of the front upright (e) a horizontal bar (p) is attached, and a bed F is placed on this bar (p). The bed F is parallel with the bar (j) and is made adjustable by means of set screws (Q) which pass through slots in the bed and into the bar (p). The bar (p) is also made adjustable on the upper end of the upright (e) by means of set screws See Fig. 1. A longitudinal groove (s) is made in the bed F to receive the rod G to be wired, and the rod is retained, or kept in the groove by a spring I-I which bears upon the upper surface of the rod, said spring being attached to a projection (t) on the bed. See Fig. 2.

From the inclined bar (g) near its upper end a horizontal bar (u) projects. This bar (u) has a bent lever I attached to it,

said lever working on a fulcrum pin ('v) attached to the bar. To the lower end of the vertical arm (fw) .of the lever a bar J is pivoted, at one end, the other end of the bar working on a bar (b) attached to the slide D. The end of the bar J that works on the bar (b) projects inward and passes a short distance underneath the bar as shown in Fig. 1. The horizontal arm of the lever I passes over the slot inthe inclined bar (g) as shown in Fig. 2.

The inclined bar (g) has a die or rod K fitted within it, and the outer end of the upper bar (f) of the lever B passes through the upper end of the die or rod K, see more particularly Fig. 3.

To the inclined bar (g) and about in line with the bar two guides (d) (a) are attached by pivots (e'), each guide has a spring (f') bearing against its outer side and a rod (g') passes through the lower end of each guide, said rods passing through oblong slots (L') in the lower ends of the guides and having eccentrics (if) upon them. The rods (g') have set screws (j') bearing against them to prevent them fromV turning casually, the screws passing into the bar (g) as shown in Fig. 3.

L is a bar which is attached to the inclined bar (g) by screws (c'). The bar L projects outward from the bar (g) at nearly right angles and has an upright plate (Z') attached to one of its sides. Within the plate (Z') at its inner end a plate M is pivoted at This plate projects above the upper edge of the plate (Z') and has two shoulders (n) (fn') formed on it, as shown plainly in Figs. l and 3.

The plate M is bent around the lower end of plate (Z') extends upward and is pivoted to a bar (0') which bar is pivoted to the outer end of the upper bar (f) of the lever B.

The operation is as follows: The bar G is fitted or placed in the groove (s) in the bed F, and the staples (29') are placed on the plate (Z') by hand or by any proper means. The inner most staple bears against a ledge (60") near the outer most shoulder (n) see `Fig. 3. The foot of the operator is placed in the strap C and the lever B is depressed and each time the bar (f) of said lever descends the die or rod K is forced downward and the two shoulders (n) are turned down below the upper edge of the plate (Z'). As the arm rises or returns to its original position the shoulders (n) (n') rise above the upper edge of plate (Z') and then will raise the inner most staple (27') which will then rest against the shoulder (u') for the st-aple as it is depressed passes under the inner most staple so that it may raise it on its upward movement. At the next downward movement of the bar and shoulders (n') the staple that was previously raised is allowed to pass over the inner most shoulder and between the guides (fl) (CZ'), and when the die or rod K ascends, said staple passes underneath its lower end the die forcing the staple into the rod G as it descends. It will be understood that a staple is fed between the guides each time the die or rod K ascends so that a staple will be driven in the rod G each time the die or rod K descends. Each time the bar (f) descends the lower arm (to) of the lever I is thrown outward and the inner end of bar J catches againstthe staple which is being driven in the rod, and when the staple is driven home a rod (5") on the bar (f) strikes the upper end of the lever E and throws the lower end of said lever free from the staple previously driven in the rod, and allows the spring A' of the lever I to actuate said lever and the bar J so as to move the bar G along the proper distance, or until the staple last driven shall strike against .the lower end of lever E, which returns to its place as the bar (f) ascends and in time to serve as a stop.

The spaces between the staples may be lengthened or shortened by adjusting the slide D and the bed F may be so grooved or arranged as to receive any form or shape of rod G, that is used.

lIn case two or more staples should be fed between the guides UZ') they will give or spring outward so that they can be discharged without difculty and without breaking or disarranging any of the parts, and the guides by adjusting rods (g) may be placed nearer together or farther apart according to the size of the staple.

This machine has been practically tested and'it operates effectually and rapidly. The

plate (Z) may be made sufliciently long to hold a large number of staples so that it will not require to be filled too often.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,

l. The means employed for feeding the staples (29') Vbetween the guides (cZ') (d') and underneath the die or rod, K, that is to say, the plate M, pivoted to the plate (Z') on which the staples are placed and provided l with the shoulders (n) (n'), the plate being connected with'the bar (f) by means of the rod (0') substantially as shown and de- 1 scribed.

2. I also claim feeding the rod G underneath the guides (d) (a7) to receive the 'staples (29'), by means of the bar J, attached to the bent lever I in connection with the lever E, said parts being operated by their respective springs A' (u) and also by the bar (f) as described.

3. I further claim the guides (cZ') (d') arranged substantially as shown to convey the staples to the rod and at the same time also allowed to expand so as to prevent the clogging of the same, in combination with the die or rod K for driving the staples into the rod.
