CORPORATION OF NEW JERSEY.
Application fi1ed June 18,
To all whom it may concern:
Be it known that I, HARVEY L. GLIDDEN, a citizen of the United States, residing at Needham Hei hts, in the county of Norfolk 5 and State of assachusetts, have invented certain Improvements in Shoe Racks, 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 shoe racks used in shoe factories to convey shoes from one operating position to another, or to store them between shoemaking operations during their manufacture.
It is necessary, especially in the case of fancy womens shoes known as millinery shoes, to hold the shoes in such a way that they will be protected from dirt or from damage caused by striking one another or other objects. A common way of seeking this result is by putting the shoes on trays mounted as shelves in shoe racks, the trays being equipped in one way or another to protect the shoes as by having pockets for individual shoes in order to keep the shoes from coming in contact with one another, which may be felt lined, or by being covered with sheets of paper to keep the shoes clean. This practice is accompanied by the serious disadvantage that these trays pick up quantities of dust and dirt which are normally floating in the air of a shoe factory and it is actually impossible to keep them clean for as much as an hour at a time. This practice also has the disadvantage of making it impossible to secure a second condltion which is that a shoe rack, at certain stages in the manufacture of certain types of shoes, should be so arranged that it will permit free circulation of air around the shoes in order to dry them out, thereby permitting an earlier removal of the lasts from The shelf structure described above impedes free circulation of air and frequently makes a difference of twenty-four hours in the period during which it is necessary for the lasts to remain in the shoes to set them properly.
Another largely successful attempt to solve this problem is found in the so-called 1921. Serial No. 478,589.
pin rack. This rack comprises a so-called pin bar extending longitudinally of the rack having pins extending laterally therefrom in direct contact with which the shoes rest. Such racks, however, have failed to give entire satisfaction under certain conditions of work because the pins themselves bruise and damage many sufiiciently delicate shoe fabrics when placed against them.
In view of these conditions, it is an object of the present invention to provide a shoe rack which shall possess among others the advantages above described as desirable without being subject to the disadvantages noted.
An important feature of the invention consists in a shoe rack equipped with a pin bar the pins of which are adapted to enter the ack pin holes in the lasts, the bar also having means such as a shoulder adapted to cooperate with the upper part of the last cone to prevent rotation of the lasts on the pins. This construction supports the shoe out of contact with any part of the rack with substantial rigidity, preventing rotation of the last on the pin so that accidental contact between adjacent shoes is impossible and at the same time provides for free circulation of the air whereby the shoes may be rapidly dried.
These and other features of the invention, including certain combinations and arrangements of parts, will be understood from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which,
Fig. l is a side elevation of a rack embodying the present invention, and
Fig. 2 is a perspective of a detail.
The frame of the rack may be made in any desired manner, a practical, convenient form of metal frame being shown in the drawing. This comprises a bottom frame 10 upon which are mounted casters 12 and to which are braced by diagonals 14: end frames 16 having cross bars 18 suitably spaced and in convenient number and in registration on the two end frames. Fastened to the corresponding cross bars 18 in any convenient manner as by bolts 20 are the so-called pin bars 22. These bars are normally made of wood and are shown as of square cross section, scarled on the ends as at 24 so as to be supported with their diagonals vertically and horizontally thereby presenting two obliquely and upwardly directed faces 26 and 28. These faces are notched at regular intervals as shown at 30, thus presenting shoulders 31, the notches alternating on o-pposite sides of the bar and being perhaps inch deep. it about the center of each notch is driven a cylindrical pin 32 projecting perhaps two inches and being of a diameter appropriate for the reception into the ordinary jack pin thimble of a last. The width of the notches 30 is slightly greater than the thickness of the top of the cone of the last the use oi which is contemplated in the rack. The lasts are placed upon the pins as shown in F 2 with the cone lying in the notch and are thus supported in position, the engagement between the cone of the last and the shoulde 31 preventing any substantial rotation on the pin so that the shoes on the lasts can not contact with each other and become bruised or damaged. T he rack as shown is, of course, adapted only for Oxford shoes from the tops of which the lasts project somewhat. The arrangement of the pins upon successive pin bars from the top to the bottom of the rack is alternating as shown in Fig. 1 so that a shoe on one pin bar will not come directly above the corresponding shoe on the next lower pin bar. This feature facilitates the entry and removal of shoes and insures a greater separation between individual shoes, thereby minimizing risk of damage. It is thus seen that my new rack will support shoes so that they cannot come in contact with each other or with the rack parts, and at the same time permits absolute freedom of air circulation around them.
The notch 30 is the preferred means of preventing rotation of the lasts on the pin 32, but other simple means for providing the projecting shoulder can be used without departing from the spirit of the invention. For example, the notch may be omitted and one or more auxiliary pins driven alongside the pin 32. Such pins may be parallel to the pin 32 as at 34-, or bent outwardly to conform to the taper of the last cone, as at 36.
Having described my invention, what I claim as new and desire to secure by Letters Patent ot' the United States is 1. A shoe rack comprising a pin bar having a pin adapted to enter the jack pin hole of a last to support it, the bar being also equipped with a member arranged to contact with the cone of the last to prevent rotat-ion on the pin. I
2. A shoe rack comprising a pin bar having a pin adapted to enter the jack pin hole of a last to support it, the bar being also equipped with an outwardly projecting shoulder arranged to prevent rotation of the last on the pin.
3. A shoe rack comprising a frame having a pin bar having notches of approximately the width oi": the upper part ota last cone, and pins in the notches arranged to engage the jack pin thimbles oi the lasts.
a. A pin bar for a shoe rack having a countersunk portion approximately fitting the upper part or a last cone, and a pin pro jecting from said countersunk portion arranged to enter the jack pin hole of the last whereby the last is supported without freedom to rotate on the pin.
5. A pin bar for a shoe rack formed of. a bar of rectangular cross section arranged with its diagonals substantially vertical and horizontal, the upward oblique faces of the bar being notched to a width substantially equal to that of the top of a last cone, each notch having a pin projecting upwardly therefrom adapted to engage the jack pin hole of the last, thereby supporting it with out freedom to turn on the pin;
6. A shoe rack havinga vertically arranged series of pin bars of square cross-section arranged with their diagonals vertical and horizontal their upwardly facing surfaces equipped with alternately arranged slots having pins projecting therefrom to enter the jack pin holes of lasts, the widths ot' the slots being arranged toreceive the tops of the cones of the lasts to prevent rotation on the pins, the pins alternating on both sides of each bar and alternating from side to sideon alternate bars, substantially as shown.
In testimony whereof I have signed my name to' this specification.
