' Specification of Letters Patent.
15, 1916. Serial No. 78,522. 7
To all whom it may concern:
Be it known that ORRELL Asi-rroN, late of Swampscott, in the county of Essex and State of. Massachusetts, deceased, invented certain Improvements in Tacking Mechanisms, 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 tacking mechanisms and particularly to such mechanisms as are adapted for driving a plurality of tacks adjacent to the edge of a shoe bottom or other article, this-application being a division of my prior application, Sci;- No. 818,571, filed Jan. 21, 1914 covering improvements in pulling-over and lasting machines.
A feature of this invention consists in a novel organization of tacker mechanism constructed and arranged to permit a plurality of tacks to be driven at uniform or predetermined distances from the edges of different shoes; The construction herein shown, by way of example, comprises a plurality of adjacent tackers connected to a common carrier, the carrier and at least one of the tackers being relatively movable, combined with means to engage the side of the shoe or other article and position the tackers relatively in response to such engagement for driving the tacks at predetermined relative distances from edges of varying contours. An advantage of this construction is that by its use a plurality of tacks can be drivenin the bottom of a shoe at the same distance from its edge unaffected by the curva ture of the edge. Another feature of this invention consists in'novel mechanism for operating the drivers of relatively movable tackers whatever may be the position of the t-ackers relatively toone another. The use of such mechanism renders possible an economy of parts in a multiple tack driving mechanism. Another feature of the invention consists in a construction and arrangement of tack holders adapting them for advantageous use in a multiple tack driving mechanism as well as in a single tack driving mechanism. These and other features 7 of the shoe bottom.
of the invention will now be described with the aid of the accompanylng drawings which anism from another angle.
Fig. 3 shows one of the tack holders separated from the other.
The invention is herein shown for the purpose of explanation as embodied in the side tacker mechanism of the pulling-over Patented Sept, 24,- 1918. Original application filed January 21, 1914, Serial No. 813,571. Divided and this application filed February 7 machine illustrated in my said earlier ap- I plication. That mechanism comprises a carrier 2 between which and the shoe 3 relative movement is niade to take place for positioning the tack holders over the edge The illustrated mechanism includes four tackers, thefirst, second and fourth of which, counting from the left in Fig. l, arepivoted at 5jto the carrier 2 while the third tacker is rigid with said carrier. Each of the'tackers' is equipped with an adjustable abutment piece 6 arranges, in the illustrative constructionshown; to engage the side of the shoe for determining the extent to which each tacker shall extend over the'shoe bottom and thereby determining the distance at which each tacker shall insert its tack from the immediately adjacent portion of the shoe edge. The first, second, and fourthtackers are each held pressed yieldingly forward by a spring S'inounted on a fixed part of the carrier 2, being limited in this movement by the engagement of walls of slots 9 with stop screws 10 which are rigid with the carrier 2. As the shoe is pressed laterally against the abutments 6 or, in the machine of said application, as the carrier 2-is yieldingly advanced toward the shoe, the abutments 6 onthe yieldingly mounted tackers engage the side of the shoe directly opposite the points where the respective tackers will insert their tacks and cause said tackers to arrange themselves according to the curvature of the'shoe edge.
As the advance continues the movement of the carrier and the rigid tacker is arrested by the work, the abutment (S on this tackcr, in the construction shown, being arranged to coat act directly with the shoe. The tackers are then located to insert their tacks each at the distance from the edge of the shoe predetermined by the adjustment of its abutment 6, and these relative distances are independent of the contour of the shoe eiilge, being the same, for example, for a shoe having a sharply curved edge as for a shoe having a straight edge.
Each of the tackers has an independent driver rod 12 the lower portion of which is guided in the mid-plate 14L or" the tacker. The upper end of the rod for the third tacker is secured to the driver bar 15, but the upper ends of the other rods are provided with hooked blocks 16 constituting a pivotal connection with a cross-head 17 of the driver bar 15. This fork and pin connection of the driver rods to the driver bar permits the rods for the first, second and fourth tackers to move out and in independently of each other and relatively to the driver bar as the tackers adjust themselves relatively for inserting each tack at the predetermined distance from the edge of the shoe for which the abutments on the individual tackers are set.
The tack holder comprises, for each tacker, parallel and closely adjacent horizontal plates 20 pivotally connected by cross plates 21 at their outer ends and pressed together by a spring 22. The plates of each pair are shaped on the adjacent faces of their inner end portions to present a tack pocket in alinement with the driver rod 12 or' that tacker. The plates 20 are formed to fit snugly the neck of the mid plate 1a which is grooved to. provide upper and lower shoulders between which the plates 20 are supported,.and the springs are strong enough to retain the holder securely in place during use, while permitting removal by the operator, for any purpose whatever, by spreading the front ends of the plates and pulling them oil backwardly without the use of any tools. a
The operation of the improved tacking mechanism has been sufliciently explained in connection with the description of the mechanism. It will be understood that the tacks may be supplied and the driver bar may be operated by any suitable means.
