FASTENING-INSEBTIN G MACHINE.

To all whom it may concern:

Be it known that I, GEORGE GoDD acitizen of the United States, residing at Vinchester, in the county of Middlese'x and State of iilassachusetts, have invented certain improvements in Fastening-Inserting B lachincs, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the devices employed in fastening inserting machines for guiding a rand or similar strip of material to the pointwhere fastenings are driven into it to secure it to a shoe or some part of a shoe. The invention will be herein disclosed as 'emhodied in a mechanism designed particularly to meet the requirements of nailed In a nailed welt shoe, as is well ood by those skilled in this art, the

upper is lasted over an insole as in a McKay shoe and a strip of welting is then secured along the margin of the shoe bottom by nails or similar fastenings driven through the welt, the upper and the insole. While this is an old and well known type of shoe, it has until recently been manufactured'in only relatively small quantities. Very recently, 11 w ve it has become more important from a commercial standpoint, and this fact has served to develop the weak points in the machinery by which shoes of this type have heretofore been manufactured. One of these weaknesses involves the devices by which the welt is guided to the point at which it is secured to the other parts of the shoe. While many devices of this character have been proposed heretofore and various types are now in use, they are all, so far as I am acquainted with them, more or less unsatisfactory due to a variety of reasons, among which may be mentioned the fact that they *Ler do not guide the welt in such manner to insure the proper location ofthe Welt on the upper and insole by. reason of defectire arrangement ofithe parts of the welt 7 guide or lack of s itable adjustments or by reason of the guide exercising insufficient control over the welt, or arerelatively complicated in construction'so as to require so many changes to enable the machines to handle tie required variety of sizes and Specification of Letters'Patent.

styles of welts, that much of an operators time is lost in making them.

It is the chief object of the present invention to devise a welt guide that will meet the practical requirements of devices of this character. The invention is directed particularly to the construction of a device of this type which shall be so arranged that all the adjustments necessary in operating on the various kinds of work can be effected quickly and easily and shall be so organized as to maintainguiding engagement with the welt substantially to the point of insertion of the fastenings and thus control the Welt effectively in the attachment of the same to the upper and insole.

The manner in which it is proposed to accomplish these objects will be readily understood from the following description of one embodiment of the invention and the novel features will be pointed out in the appended claims.

Referring now to drawings,

Figure l is a view in front elevation of a fastening inserting machine equipped with a welt guide constructed in accordance with this invention;

Fig. 2 is a cross sectional View illustrating the manner in which a fastening is driven through a welt tosecure it to the other parts of a shoe and showing in cross section the parts of the machine and the guiding devices adjacent to the point of insertion of the fastening;

Fig. 3 is anangular, exploded view of the welt guide and parts associated therewith;

-Fig. a is an angular view showing the lower side of the guard plate of the machine shown in Fig. l. with the welt guide provided by this invention attached thereto.

In the drawings the guiding devices are shown applied to a machine of the type disclosed and claimed in the co-pending appli cations of Fred L. Mackenzie, Serial No. 137,152, filed December 15, 1916, and of George Goddu and Fred L. Mackenzie, Serial No. 137,571, filed December 18,1916, and designed to use string nails. Inasmuch as this is a commercial form of fastening insertin machine put out by the assignees of the present invention and one with which the trade is familiar, no detailed descripthe accompanying tion of it is necessary, particularly since the welt guide provided by this invention is equally applicable to loose nailing machines and many other types of fastening inserting machines. For the present purposes it is sufficient to state that the fastening inserting mechanism includes a guard plate 2 having the usual hardened cap plateA: and is provided with a passage 6 through which the 'astenings are driven and in which also the awl works. Fig. 2 shows a throat 8 of the fastening inserting mechanism just after it has positioned a fastening and the driver has driven this fastening into the work, the horn tip which supports the work at the point of insertion of the fastening being indicated at 10.

The guard plate 2 has a len shank 12 extending backwardly by which it is secured to the frame of the machine and the welt guide provided by this invention. is mounted on one side of the shank portion of the guard plate. This device is best shown in Figs. 3 and 1 and comprises a part 14 having a welt guiding slot 15 formed through its forward end and also having two welt edge guiding members 16 and 18 respectively. The welt W, Fig. 1, is unwound from a reel 20 on which it is coiled and is brought through the slot 15 and under the cap 4 of the guard plate 2 into substantially the position in which it is shown in Fig. 2. It is especially desirable, of course, to control the position of the welt at the point where the fastenings are driven through it so as to insure its accurate placement on the shoe; and the two welt edge guiding members 16 and 18 therefore are extended forward from the slot 15 under the guard plate. to points opposite the passage 6 through which the fastenings are driven. The upper and lower walls of the slot ,15 of course guide the top and bottom faces of the welt and position the weltver- 'tically, while the members 16 and 18 position the welt laterally with reference to the guard plate. These parts cooperate with the work at the instant the fastening is being driven, to surround the welt on all sides ad jacent to the point of insertion of the fastenings as clearly shown in Fig. 2, so that if these members are properly adjusted and the work is properly presented to the machine there is no possibility of attaching the welt improperly to the shoe.

It will be noted that the welt guiding slot 15 points toward the lower face of the guard plate 2 so that it directs the welt toward the point of insertion of the fastenings. Since the members 16 and 18 extend away from this slot in the direction of the feeding movement of the welt they are operative to guide the welt after it has passed through the slot 15. The position of the welt thus is controlled from the time it enters the welt guide until it is secured to the shoe.

Inasmuch as it is sometimes desirable to replace the welt edge guiding member 16 with a similar part of different shape or dimensions, and since this part wears out more rapidly than the other parts of the device, I prefer to secure this member rcmovably to the part 14: rather than to make it integral with said part. For this purpose the end face of the part 1 1 is grooved to receive a tongue with which the member 16 is provided and this member is secured to the part 14 by a screw 22.

It is, of course, necessary to use welts of different widths on different kinds of Work, and in order to provide for the proper guiding of these various widths of welts, the welt edge guiding member 18 is mounted for adjustment toward and from its companion member 16. w In the construction shown, the member 18 extends through the Welt guicL ing slot 15 and is provided with a shank which is slotted to receive a screw 26 that clamps this member adjustably to a lug 28 projecting upwardly from the part 14:, as

clearly shown in Fig. 3. This constructionthus provides for a relative adjustment of the two members 16 and 18 to vary the distance between them. The location of the adjustable edge guidiugmember 18 in the slot 15 is of advantage in maintaining this member in the same plane as its companion member 16, while the clamping screw 26 is loosened and its adjustment is being effected, thus preventing any displacement of this member other than that desired while the adjustment is being made.

lt will readily be appreciated that the construction above described, while very simple, still performs all the functions required of a device of this character and that the several adjustments can be easily and quickly made. It willbe noted that one adjustment only is necessary for any single change in conditions; that is, it is necessary merely to adjust the member 18 to provide for a change in the width of the welt used, or to adjust the member 14: if it is desired to change the distance from the edges of the welt at which the fastenings are inserted.

It is not only necessary to make provision for adjusting the device for various widths of welts but also to provide for adjusting the welt edge guiding parts relatively to the passage 6 in a direction transverse to the direction of movement of the welt through slot 15 for the purpose of varying the distance from the edges of the welt at which the fastenings will be inserted. To this end the part 141- is provided with two slots through which machine screws30 extend the adjustment made for the width of the welt. In other words, all the welt guiding parts are adjustable as a unit. At the same time any change in the relative adjustment of the edge guiding members requires no change in the adjustment of the part 14 unless it is also desired to change the distance at which the fastenings will be inserted from the left hand edge of the welt as the parts are seen in Fig. 2.

In order to guide the shoe properly with reference to the passage 6 in the guard plate and to the welt guiding members, an

edge gage 32 is provided which bears on the upper of the shoe opposite the edge of the insole. Thi gage may be of any suitable form but, in the machine shown, it consists of a roll 32 mounted to rotate freely on a stud 34 projecting upward from the forward end of bracket plate 36. As clearly shown in Fig. 2, the upper forward edge of this roll overlaps the inner welt edge guiding member 18 so that it coiiperates with the welt guide in positioning the welt properly at the point of insertion of the fastenings.

In machines of this general type the work is fed forward by an awl with which the machine is equipped and which advances the work step by step between successive fastening inserting operations in a direction parallel to the direction of length of the passage 6 in the guard plate. It is sometimes desirable to change the position of the edge gage 32 with reference to the path of movement of the awl in a direction parallel to this path, particularly in changing from broad toed shoes to those having pointed toes or vice versa. For this purpose the bracket 36, which carries the roll 32, is provided with a series of teeth that interlock with similar teeth on the lower face of a slide 38, and these two parts are secured together by a bolt 40 that projects through a slot formed in the bracket 36 and which extends in a direction parallel to the teeth. These teeth lie parallel to the direction of the feeding movement of the work so that the gage 32 may be adjusted parallel to this path and then secured in an adjusted position by the bolt 40.

This edge gage also is mounted for adjustmentin a direction at right angles to that of the adjustment just mentioned; that is, at right angles to the path of feeding movement of the work. This adjustment, as is well understood by those skilled in this art, is desirable for the purpose of effecting a relative displacement of the shoe and the guard plate 2 while the welt is being attached to certain parts of the shoe. For instance, in order to have the welt project the same distance beyond the upper at all parts of the shoe. it obviously is necessary to have the gage 32 occupy a different position when the machine is attaching the welt to the fore part of the shoe from that which it occupie while the welt is being attached to the shank portion of the shoe. To this end the slide 38, which lies just below the shank 12 of the guard plate, is clamped by means of a bolt 46 extending through a slot 48 in the slide, to a short rack bar 44 that lies on the upper face of the shank 12. A depending part 50 of this rack bar is located in the slot of the shank 12 and spaces the parts 44 and 38 apart sufficiently to allow them to slide freely on the shank 12 longitudinally of the slot 52, which, as shown in Fig. 3, lies at right angles to the direction of the feeding movement of the work. For the purpose of effecting the adjustment of the gage 32 conveniently, a small pinion (not shown) is mounted to mesh with the teeth of the rack 44 and is arranged to be rotated by a movement of a handle 54 (see Fig. 1) which is located within the convenient reach of the operative.

By swinging this handle the pinion slides the rack 44, and with it the gage 32, toward or from the passage 6 in the guard plate. The extent of this adjustment is controlled by two stops 56 and 58, respectively, and by a shoulder 60 on the slide 38. The stop 58 is secured by a bolt 62, projecting through a slot formed in the stop, to the edge of the shank 12 of the guard plate and consequently is stationary. The shoulder 60, by engaging the rear face of this stop limits the forward movement of the gage 32; while the stop 56 engages the forward face of the stop 58 upon the backward movement of the slide 38 and thus limits the rearward movement of the gage 32. A bolt 64 projecting through a slot formed on the stop 56 secures this member adjustably to the slide 38. Inasmuch as both the stops 56 and 58 are adjustable in directions parallel to the direction of the adjusting movement of the edge gage and since the slide 38 also is adjustably secured to the rack bar 44, any desired range of movement of the gage 32 may be obtained.

While the embodiment of the invention now preferred by me has been herein shown and described, it is obvious that the inven tion may be embodied in other forms diflering in detail from that herein disclosed but still retaining its essential characteristics.
