IPOB-A-TIQN' GF NEWT J LASTING Application filed November 16, 1931, Serial No.

This invention relates to lasting machines for use in the manufacture of shoes, and more particularly to machines having wipers for wiping the marginal portion of an upper int-o lasted position about an end of a shoe and means for driving fastening-s to fasten the upper in lasted position. The invention is herein illustrated as applied to a machine for lasting the heel ends of shoes, of the same general type as that disclosed in Letters 0 Patent No. 1,583,044, granted on May 4, 1926,

upon an application of C. H. Hoyt and pro vided with upper-fastening means of a type more particularly disclosed in Letters Patent N o. l,852,0l'5, granted on April 5, 1932, upon an application of J. G. J orgensen. It is to be understood, however, that the invention is not thus limited in its applicability.

In accordance with the disclosure of the last-mentioned Letters Patent the upperfastening means comprises drivers movable in directions substantially perpendicular to the plane ofthe wipers to drive tacks through the upper into the shoe bottom, and means forholding the tacks with their shank portions inclined inwardly away from the edge of the shoe bottom when they are in positions to be driven so that they enter the shoe in suchinclined directions when they are driven. An object of the present invention among others, is to provide in an organization of that general character improved means for holding or controlling the tacks or like fastenings -whichw-ill be simple in construction, unlikely to get out of order and readily accessihle when desired. For the purposes in view the tack-holding means herein shown comprises spring-pressed members arranged to suspend the tacks by their heads with their shank portions inclined as above described and yieldable to permit the heads of the t acks to pass as the tacks are driven, theseme-mbers, as illustrated, consisting of balls arranged to extend part way only across passages through whichthe tacks are driven and to engage the heads of the tacks at the sides thereof that are farthest from the edge of the shoe bottomwhen the tacks are in-positions to be-driven. The construction shown comprises upper-fastening mechanisms that ivraonrnn 575,30 and in. Great Britain Decemberfl, 1930..

are movable inwardly over the shoe bottom w1th the wipers in the same general manner as dlsclosed in the last-mentioned Letters Patent, and the tack-controlling members" are pressed yieldingly into the paths of the tacks in directions substantially opposite to. the directions of closing movement of the respective wipers over the shoe bottom. These members, moreover, as illustrated, are mounted in openings thatextend to the sides of the different 7 I other across the shoe bottom in the wiping operation, so that they are readily accessible at any time.

In accordance with a further feature, the invention provides improved means to adapt, the machine to operate on shoes of different sizes. For this purpose the wipers herein shown have each a readily detachable end portion provided with a wiping face forming an extension of the wiping face of the rest of the wiper and provided with means for supporting one of the upper-fastening tacks in position to be driven.

The above and other features of the invention, including also novel means for supporting the heel band with which a machine of the illustrated type is customarily provided, and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawing and pointed out inthe claims.

In the drawing Fig. l is a plan view of a portion of a ma: chine in which the invention is embodied, parts of the structure being removed;

Fig. 2 is a plan viewon an enlarged scale of a portion of the structure shown in Fig. 1;

Figs. 3 and 4 are sections on the lines KID-1H and Il -IV respectively of Fig.

2, showing also portions of the structure.

omitted from Fig, 2 and F 1g. 5 is a view in front elevation showing the heel band and its supporting means, and 7 also a portion of the wiping and fastening means.

As more fully disclosed in the above-men tio-ned Letters Patent, the machine in which the invention is herein illustrated as emor PATERSON, new Jnnsn A son;

bodied comprises a pair of wipers 10 formed to embrace the heel end of an upper and movable to wipe the marginal portion of the upper inwardly into lasted position over a sole or insole on a last. These wipers are supported on a slide 12 which is movable to advance them bodily lengthwise of the shoes and on which they are guided for swinging movements about an axis extending heightwise of the shoe to close them inwardly toward each other laterally of the shoe. For imparting the swinging or closing movements to the wipers there are provided slides 14, one for each wiper, mounted on the frame of the machine for movement-s laterally of the shoe, each slide having an end portion 16 provided with a slot 18 in which is mounted a roll 20 carried by the adjacent wiper. The slots 18 extend lengthwise of the shoe to permit advancing movement of the wipers relatively to the slides 14. Each of the slides 14 carries a rack bar 22 engaged by a pinion 24 which is engaged and operated by a curved rack 26 formed on one end of a bell-crank lever 28 pivoted at 30 on the frame of the machine, the other end of this lever having thereon a curved rack 32 engaged and operated by a rack bar 34. The construction shown comprises means more fully disclosed in a copending application of Fred Ricks, Serial No. 562,083, filed on September 10, 1931, for imparting to the wipers first advancing movement lengthwise of the shoe without any closing movements, then simultaneous advacing and closing movements, and thereafter closing movements only to complete the overwiping operation. For this purpose the two rack bars 84 are carried by a wlper closing slide 86 which is operated independently of the wiper-advancing slide 12, and on these two slides are mounted rolls 38 and 40 respectively which are engaged and operated by a cam (not shown) to 1mpart to the wipers movements in the above-mentioned order, as

disclosed in said Ricks application.

For fastening the heel end of the upper in lasted position the machine herein shown is provided with upper-fastening mechanisms associated respectively with the different wipers 10 and movable with the wipers inwardly over the shoe bottom in the same general manner as disclosed in the above-mentioned Letters Patent No. 1,852,015, each of the mechanisms including a plurality of tack drivers 42 movable in directions substantially perpendicular to the plane of the wipers to drive upper-fastening tacks through the wipers into the shoe bottom, together with means for holding the tacks with their shank portions inclined inwardly away from the edge of the shoe bottom when they are in positions to be driven. For positioning and controlling the tacks, in accordance with one of the features of the present invention, each wiper 10 is provided with an upstanding portion or flange 44 curved similarly to its wiping edge and in which are formed a plurality the wipers and in alincment with driver guide passages 48 formed in a block 50 which is secured on the wiper in the same general manner as disclosed in the last-mentioned Letters Patent. Formed also in each flange 44 are a plurality of cylindrical openings 52 (Fig. 3) spaced above the wiping face of the wiper and extending from the different respective tack passages 46 to the concave side of the flange which faces the flange 44 of the opposite wiper across the shoe bottom. Mounted in each of the openings 52 is a small steel ball 54 which is snugly guided in the opening and is arranged to extend part way only across the tack passage 46 to engage the head of the tack at that side thereof which is farthest from the edge of the shoe bottom when the tack is in position to be driven and thus to suspend the tack by its head with its shank portion inclined inwardly away from the edge of the shoe bottom, as illustrated in Fig. 8. The extent to which the ball may thus project into the tack passage is limited by a reduction of the bore of the opening 52 at the end of the opening next to the tack passage. The diameter of the ball is such that when it is thus positioned a portion of it projects also from the concave face of the flange 44. The balls that are carried by each wiper are pressed into the tack passages in directions substantially opposite to the direction of closing movement of the wiper and its associated fastening mechanism over the shoe by a series of depending spring fingers 56 formed on a. comb-like member 58 bent in a concave form and secured to the concave face of the flange 44. When the tacks are driven by the drivers 42 these fingers yield to permit the heads of the tacks to pass the balls 54. It Will be understood that each ball, while obstructing the tack passage sufiiciently to prevent the tack from falling through it by gravity, affords on its rounded surface merely a single point of support for the lower surface of the tack head at the side of the tack which is nearest the concave face of the flange 44, so that the tack is suspended by its head in an inclined position with its point just above the lower face of the wiper and in contact with that side of the tack passage 46 at which the ball is located.

It will be evident that the above-described construction is simple to manufacture, durable and not likely to give any trouble by reason of an obstruction in any of the tack passages. The balls 54, moreover, are readily accessible, since all that is necessary if it is desired to remove or replace any of them is simply to remove the appropriate spring member 58.

To adapt the machine to operate in the wiper 10, in accordance ture of the lnvention,

is attached and rib 62 between best manneron shoes that. dilfer widely in size. with considerable. corresponding variae tions in the lengths of the heel seats, each with. a. further. feais-provide dwith a readily. detachable end portion 60 (Fig. 4) located at the end. thereof whichis farthest from the extreme end. of the shoe and pro? vided with means forsupporting one of the tacks in position to be driven. Each detachable end portion 60 has a wiping face that forms an extension. of the wiping. face of themain portion. of thewiper to which. it has a horizontally extending which and thelower. part of the end portion the main portion of the wiper extends to hold the difierent portions in verticallyfixed relation to each other. Thereis also a tongue (Seton therib 62 which inter? looks with a groove in the block to hold the different portions in fixed relation to each other with respect to movement laterally of the shoe while permitting the endportion to be detached by sliding it in a forward direction. To hold the end portion 60 in place there is provided a latch 66 which is pivoted on the block 50 within a recess in the block and may be turned either into or out of a notch formed in the rib 62. The latch has a head 68 thereon accessible to the operator and provided with a slot adapted to receive a screw driver whereby the latch may be turned. Eachdetachable end portion has a flange 44 thereon which serves as an eXtension of the flanged l and is provided with a tack passage 46 in alinement with a corresponding driverpassage 48 in the block 50. There is also a ball 54 and a spring 56. which perform the functions of the corresponding:

parts on the main portion of the wiper, the spring 56 being fastened to the front face of the end portion 60 and extending rearwardly into position to control the ball 54: as illustrated in Fig. 2.

The machine herein shown, similarly-to that shown and described in the previously mentioned Letters Patent No. 1,583,044, is provided with a heel band supported near its forward ends by clips 72 on rods 74 in such av manner as to permitrelative sliding movements lengthwise of the hand between the clips and the end portions of the band as the band is closed around the heel end of the shoe. The present invention further provides additional means for supporting the end portions of the band against downward tipping movement such as might result from the tendency of the wipers to tip the shoe when they first meet the heel end of the shoe. This additional meanscomprises blocks 76, secured on the outer faces of the end portions of the band between its upper and lower edges and provided with ribs 78 which are slidable in directions lengthwise of the band in grooves formed in blocks 80 which are fast on the rods 74. By these riband groove connections the forward ends .of the band are ad: ditionally supported against downward movement with provision for relative move ment lengthwise of the shoe between the blocks 76and 80 as the end of the shoe.

It is to be understood that in its more general aspects the invention is not limitedtoan organization in which the tack drivers. are movableinwardly over the shoe bottom with the wipers, as herein shown, nor in which the drivers are movable perpendicularly to the plane of the wipers to drive the tacks; nor limited to an organization for driving fastenings in the form of tacks.
