4 Claims.

This invention relates to improvements in apparatus for use in covering heels.

In covering wood heels it is customary for a single operative first to apply cement to all the heels and covers of a large number of heel-andcover lots and to set the cemented heels and covers aside to allow the cement to become tacky so that the covers Will properly adhere to the heels and thereafter to pull the covers on the heels leaving the cover margins projecting beyond the attaching, the top-lift-receiving and the breast faces of the heels, and as each heel is covered to finish the heel by trimming and snipping the projecting cover margins and pressing them down against the work. This mode of operation results in the use of a large amount of bench or rack space in the heel-covering plant for holding the cementedrheels and covers, and, moreover, since the finishing operations above referred to take approximately twice as long as either the Ycementing or the pulling-on operations, large quantities of heels and covers are forced to remain idle for a much longer period of time than required for proper conditioning of the cement and consequently the progress of the work through the factory is unnecessarily delayed.

In view of the foregoing, one object of the present invention is to provide an improved heelcovering stand, the use of which will facilitate the operations of pulling on heel covers and trimming, snipping and tucking down the cover margins, and which will assist in eliminating the diS- advantages above referred to with reference to delays in the performance of the heel-covering operations by the methods heretofore generally practiced.

To the accomplishment of this object one feature of the present invention consists in the provision of a covering stand which, as herein illustrated, comprises a heel clamping jack for use in pulling covers on heels, and a work bench having a front portion supporting said jack and shaped at the opposite sides of the jack to afford clearance for the arms of an Voperator using the jack, said bench having a rear portion of a construction providing a support located within arms reach of the operative of the jack for receiving covered heels and providing also bench spaces for the use of two finishing operatives stationed one at each side of the bench and within arms reach of said support.

The illustrated bench is provided with two racks which are located at opposite sides of the jack, one -of the racks being adapted to hold a tray of cemented heels at the level of the bench and within 1933, Serial No. 662,324

convenient arms reach of the operative of the jack while the other rack is adapted to hold three trays of cemented heel covers also within convenient arms reach of the operative of the jack, the trays of covers being supported one above the other, with the lowermost tray at the level of the bench. At the rear of the bench, between the portions used by the finishing operatives, the bench is bifurcated or cut away to permit finished heels to be dropped through a central opening into a box suitably positioned upon a support beneath the bench, and two counting devices are or may be located just above the opening in the bench, one counting device for each nishing operative-forcounting the finished heels as they l5 are being dropped into the boX.

The invention further consists in the features of construction and combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art.

The invention will now be explained with reference to the accompanying drawings, in which Fig. 1 is a perspective View of my improved covering stand;

Fig. 2 is an elevational view of the left-hand side of the covering stand, portions thereof being broken away to disclose certain structural features;

Fig. 3 is a fragmentary top plan view of the 30 covering stand showing a tray of heels and trays of covers located in their respective positions on the stand; and

Fig. l is a detailed sectional View taken substantially along the line IV-IV of Fig. 1. 35

Referring to the drawings, the covering stand consists of a unitary metallic structure comprising, in general, a work bench I, a rack I2 which is located at the left-hand side of the bench, and a rack I4 which is located at the right-hand side of the bench. The bench I0 is supported upon four legs I5 at a convenient height for use by operatives seated around the bench. The front of the bench is formed with a relatively narrow, forwardly projecting portion I8 upon which is mounted a heel clamping jack 20 for holding a heel, such as the heel A (Fig. 2) while a cover is being pulled thereon by a covering operative seated in front of the jack at what may be termed a covering station B. Immediately behind the narrow projecting portion I8 of the bench the lateral edges of the bench diverge rearwardly, as indicated at 22. Thus the portion of the bench which supports the jack 20 is shaped to provide ample arm and elbow room for an operative using the jack and in that way to facilitate the operation of clamping a heel and pulling a cover thereon. The jack 28, as best shown in Fig. 2, comprises a C-shaped frame 26 which is rigidly secured to the bench and which carries an adjustable upper clamping member 28 for engaging the top-lift-receiving face of a heel. Cooperating with the upper clamping member 28 in clamping a heel is a movable lower clamp member 32 which is adapted te engage the attaching face of the heel. The lower clamp member 32 is Pivoted at 34 to the frame 26 and is formed with a rearward extension 36 which is connected by means of a rod 38 with a foot treadle 48 which is pivoted to a floor bracket 42. A spring 44 attached to the rear extension of the lower clamp member 32 tends to hold the clamp normally in open position, the arrangement being such, that depression of the treadle 48 will operate the clamp to hold a heel firmly in the position shown in Fig. 2. The construction and mode of operation of the jack itself, however, is similar to that of jacks customarily employed by wood heel covering operatives.

The rack l2 is adapted to receive a tray of heels to be covered, such for example as the tray C (Fig. 4) and to support the tray in a horizontal position at the level of the work bench and conveniently close to the jack 28, elbow room for the operative, however, being provided between the forward extension I8 of the bench I6 and the tray C. The illustrated rack I2 consists of a skeleton shelf formed of a U-shaped strip 46 the opposite ends of which are secured to angle irons 48 carried by a horizontal bar 58 which, in turn, is secured to one of the diverging edges 22 at the left-hand side of the bench I0. As shown, the strip 48 is rigidly supported by means of a brace 52 secured at one end to the middle of the strip and at the opposite end to one of the legs I8. The rack I2 is particularly designed for supporting and positioning a heel tray or screen of a construction substantially like that of the illustrated tray C. As shown in detail in Figs. 3 and 4, the bottom of the tray C is set in a thin rectangular frame C which constitutes the rim of the tray. To insure that the tray C shall be firmly held and positively located in a predetermined angular position with respect to the bench I0 the angle irons 48 and the bar 58 are constructed and relatively arranged to afford al channel-like holder for receiving one end portion of the frame or rim C of the heel tray so that when the tray is placed with the bottom of the tray resting upon the strip 46 one end of the frame C will be confined within the channel above referred to and the tray will be positioned as shown in Fig. 4. When thus positioned, displacement of the tray in a direction away from an operative at the covering station B is prevented by means of a stop 58 formed by bending outwardly the rear extremity of the bar 50 and displacement of the tray in the opposite direction is prevented by engagement of the front edge of the tray with the forwardly projecting portion I8 of the bench. The bar 5U and the angle irons 48, by engaging opposite sides of the end portion of the frame C', serve to prevent displacement of the tray in directions toward and away from the sloping edge 22 of the bench. Thus the tray is definitely positioned in a predetermined angular relation of substantially 45 with respect to the front of the work bench. As shown, the tray C is located within convenient arms reach of the operative at the covering station B so as to facilitate transfer of heels from the tray C to the jack 20.

The rack I4 is adapted to provide support for three heel cover trays, such as the trays indicated at D in Figs. 2 and 4, the construction of 5 the rack being such that the trays are supported in horizontal planes located one above the other with ample clearance space between them and with the lowermosttray disposed substantially at the level of the work bench and spaced away from l0 the projecting portion I8 of the bench and the adjacent edge 22 to afford elbow room for the covering operative. As shown, the rack I2 cornprises a lower skeleton frame or shelf 62 which, as best shown in Fig. 1, is constructed of angle 15 bars riveted together at their ends so as to form a rectangular frame. The illustrated shelf 62 is supported by means of four legs 64 and is rigidly secured to the bench I G by means of a bracket 66. the latter being so located as not to interfere 20 with the actions of the covering operative in transferring covers from the cover trays to the jack and pulling on the covers. Two of the legs 64 of the rack I2 are disposed at the rear of the frame 62 and are extended upwardly, as shown at 25 58, to provide support for the two upper shelves 'IEB and 'l2 of the rack, each of which, as shown, is formed of a U-shaped strip the opposite ends of which are riveted to the upward extensions 68 of the rear legs 64 and are rigidly supported by 30 means of braces lll. A brace 'I6 is secured at its upper end to one of the rear legs 64 and is adapted to be secured at its lower end to the oor so as more rigidly to support the rack I4 in order to c. prevent undesired vibration thereof. As shown, 35 the lower shelf S2 is wider than the upper shelves 'I0 and l2, the lower shelf being extended toward the bench I8 to enable the lower tray to be pulled toward the jack by the covering operative as may be desirable to afford better access to the covers lying upon the right-hand portion of the tray.

Upon the work bench IG at the rear of the jack 2G, as best shown in Fig. 4, is provided bench space 'I8 for receiving heels upon which the covers have been pulled by the operative at the covering 45 station B. This bench space 18 which constitutes a receiving support for the covered heels is located within convenient arms reach of the covering operative. As each heel is covered, the covering operative removes it from the jack and places ist) it upon the receiving support 18, where the heels may accumulate in a pile, as indicated at E in Fig. 3. The work bench l0 is adapted to afford at opposite sides of its rear portion ample bench spaces or working areas and 82 for two finishing YK5 operatives (located at two finishing stations designated respectively F and G) who are to perform the operations of trimming, snipping, and pressing down the cover margins which project beyond the heels after the covers have been pulled thereon. Between the working areas 88 and 82 at the rear of the work bench l0 the bench is bifurcated or cut away, as indicated at 84, to receive two counting devices 86 and 88 for use by the finishing operatives at stations F and G, respectively, in U5 counting the finished heels as the latter are dropped through the counting devices into a suitable container such as the box H. The opening or cut-away portion 84 serves also to separate the areas 80 and 82 to avoid interference between the 7l) operations performed by one finishing operative and those performed by the other finishing operative. The separate counting devices 86 and 88 afford means for comparing the amount of work M accomplished by the two finishing operatives andi-'5 also for checking the quantities of heels in the different lots with the quantities specified by order tags one of which accompanies each lot of heels. The two counting devices 86 and 88 are similar in construction and each embodies features which are described and claimed in United States Letters Patent No. 2,015,147, granted September 24, 1935, upon application of R. F. Knight. The box H is supported by two spaced angle-iron guides or supports 90, the box being introduced from the rear of the stand and slid forwardly along the guides 90 until its forward end engages abutments 92 which are secured to the guides 90 and which locate the box in position to receive the heels. The guides 90 and the abutments 92 are made adjustable to accommodate boxes of different sizes. As shown, each guide 90 consists of an angle iron strip the ends of which rest upon horizontal crossbars 94 that are secured to the legs I6 and serve also as braces for the legs. The guides 90 are secured to the crossbars 94 by means of bolts 96 and a plurality of bolt-receiving holes 98 are provided in each crossbar to enable the guides to be adjusted to accommodate heel boxes of different widths. The abutments 92 are secured by bolts IDB to the guides 90, a plurality of holes |02 in each guide permitting the abutments to be adjusted lengthwise of the guides to accommodate heel boxes of different lengths. A cement cup |05 secured to the bench ID, in front of the counting devices 86 and 88, is adapted to contain liquid latex for use by the finishing operatives, if necessary, to insure proper adherence of the cover margins to the wood when they are pressed down.

It would be apparent from the above description that the construction of the parts constituting the covering stand is such as to enable a team of three operatives to operate in an eflicient and expeditious manner to pull covers on successive lots of heels, to perform the necessary trimming, snipping and pressing down operations upon the margins of the attached covers, to count the finished heels, and to deliver the successive lots into separate receptacles ready for attachment to corresponding lots of shoes. Moreover, the construction of the stand and the arrangement of its component parts is such that al1 the above-mentioned operations may be performed and the heels transferred from the covering operative to the finishing operatives, without the necessity of any operative leaving her respective working station.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
