SHELVING.

SPECIFICATION forming part of Letters Patent No; 714,206, dated November 25, 1902.

Application filed February 25, 1901. Serial No. 48,670- (No model.)

To coll whom, it may concern:

Beit known that I, JAMES M. LIPPINCOTT, a citizen of the United States, residing at Oakland, in the county of Coles and State of Illinois, have made certain newand useful Improvements in Shelving, of which the following is a specification.

My invention is an ilnprovement in that class of shelving in which a shelf-section is movable vertically to a height above the ordinary fixed shelving and then adj usted back over said shelving-such, for instance, as shown in my former patent, No. 641,212, dated January 9, 1900; and the present invention has for an object, among others, to simplify the construction and to provide means whereby to render the apparatus easier to operate, more efficient, and to improve its general appearance; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described an claimed.

In the drawings, Figure 1 is a perspective View, partly broken away, ofa number of shelving-sections embodying my invention, one of the movable shelving-sections being raised to its uppermost position and another lowered to a point in front of the fixed shelving-section. Fig. 2 is a vertical longitudinal section on about line 2 2 of Fig. 1. Fig. 3 is a'vertical longitudinal section on about line 3 3 of Fig. 1. Fig. 4 is an enlarged sectional View of the upperv portion of the apparatus with the parts in the position shown in Fig. 2. Fig. 5 is a ltop plan view of the apparatus, partly broken away. Fig. 6 is a detail perspective view of the top portion of the movable shelving-section. Fig. 7 is a detail sectional view illustrating the construction of the shelving-pulleys with rollers to take the end thrust. Fig. 8 is a detail sectional v iew illustrating the flanged rail and the grooved pulley. Fig. 9 is a detail perspective view,

for the shelf-blind. Fig. 10 is a detail sectional view illustrating the spring-stop. Fig.

In carrying out my invention I provide a fixed shelving-section A, and above the same a space to receive the movable shelving-section B. Ordinarily in shelving it is desirable to provide a projecting shelf upon which to support the goods which are being used in making a sale, and this is usually effected by elevating the base of a fixed shelving-section and providing a projecting shelf permanently fixed at a suitable height; but Where the movable shelving-section is employed this projecting fixed shelf forms an obstruction to the downward movement of the'shelving-section and necessitates the shortening of such section or requires a greater height of space in which to adjust the shelving-section when not in use than is ordinarily available. For

vthis reason I prefer to provide the fixed shelving-section A with a sliding shelf C, which may be moved in, as shown in Figs. 2 and 3, when not in use or when the movable section is drawn down to the position shown in Fig. 3, or such sliding shelf O may be drawn outward, as shown at the left in Fig. 1, to form a shelf on which to expose the' goods whenever desired. I prefer to provide suitable guides at C' for the sliding shelf and to provide at the outer edge of such shelf a rib or bead O2, which can abut the outer edge of the shelf adjacent to which the sliding shelf operates, as will be understood from Fig. 1. This shelf C, it will be seen, can be readily adjusted in out of the way when not in use and can be drawn forward, as shown in Fig. 1, whenever desired. I also prefer to provide one of the shelves of the movable section B with a similar sliding shelf D, which can be operated, as shown in Fig. 1, when the movable section is lowered or when otherwise desired. The movable shelving-section B may preferably be made very light, and where there is a considerable span of shelving I prefer to provide between the ends of the shelvesy B of the movable section stay-rods E, which extend between the shelves B', as shown, and support the base-bars E, which extend transversely beneath the shelves and are held by means of nuts E2. on the rods E. By preference the rods E pass through slots b', elongated in the direction of length of the shelves B, so the rods can 'be-adjusted toward the ends of the shelves one way or the other to for the shelves B are usually arranged in two parts, the lower rod bracing the shelves be- IGO low and the upper rod the shelves above the shelf adjacent to which the sliding shelf D operates, as will be understood from Figs. 1, 2, and 3.

In practice the movable shelving-section B may be made of wood, aluminium, or other suitable material, or when desired both wood and aluminium or other light metal may be employed in the construction of the movable section in such manner as to enable the production of a light strong shelving-section.

The movable shelving-section B is provided at its upper rear corners with rollers F and at its upper front corners with rollers G, the rollers F `being arranged tooperate in vertical gnideways H, which curve rearwardly at their upper ends into the rearwardly-extending guideways H', and the front rollers G operate in the guideways I, which latter extend in advance of the guideways H' and in alinement therewith and curve downwardly at their ends I to permit the entrance and exit of the rollers G in raising and lowering the shelving-section B. I prefer to arrange the guideways I for the rollers G in horizontal alinement with the guideways l-I', as thereby I avoid any elevation of the guideways for the front rollers above those for the rear rollers of the movable shelving-section and am .thus able to provide an apparatus which will present a better appearance at its upper end. The guideways H, H', and I form tracks for the rollers of the movable shelving-section, and where desired tracks may be provided with a rail or flange .I and the pulleys may be be grooved, as shown'atj in Fig. 8, to prevent any lateral play of the movable shelvingsection; but I prefer to employ the construction shown in Fig. 7, in which the trackways shown at 1 are simply channeled or grooved in one side and the rollers are formed to 'fit in such channel and include a main roller or wheel 2, which supports the load or weight of the movable shelving-section, and a roller 3 to take the end thrust, the axis of the roller 3 being at right angles to that of the roller 2 and such roller 3 being carried in a yoke 4, which is journaled at 5 concentrically with the axis of the roller 2, so the roller 3 may operate universally. The rollers 2 and 3 may be covered with rubber, or the trackway may be covered with rubber, or rubber may be provided on both parts, if desired, to decrease the noise incident to the operation of the apparatus, and the roller or its track, shown in Fig. 8, (or both,) may be made of hard rubber or other suitable material to deaden the noise.

The ropes K, of wire or other material, for raising the shelving-section extend from such shelving-section upwardly over guide-pulleys K', thence downward from guide-pulleys K2, and connect with the weights L, which are preferably flanged at L' to slide in grooves L2, and so prevent anyjamming of the weights in the wells in which they operate. It may be preferred to form the weights in sections or plates, as shown in Figs. 2 and l1, the plates beingslotted at L3, so they can be added and removed as desired to secure a proper counterbalance of the load upon the shelvingsection B. By this means from time to time weights may be applied and removed according to the weight ofthe goods upon the shelving-section. In connecting the cord K with the movable shelving-section it is preferred to provide means for movably connecting the cord with the section, so the stress of the cord will not hinder the horizontal moving of the shelving-section, and this may preferably be accomplished by providing pulleys M on the cord K, operating in loops or frames M, extending transversely upon the upper end of the movable shelving-section. These frames M operate to strengthen the shelving-section, and I may also form the brackets carrying the rollers F and Gr to overlap the corners of the shelving-section B and strengthen the same, as will be understood from the construction shown at f at the rear of section B in Fig. 6. The section B is provided with a suitable handhold N, which may be grasped by the hand in raising and lowering the shelving and may be engaged by a pole when necessary.

In connection with the movable shelvingsection and the xed section below the same I prefer to provide a shelf-blind O in the form of a curtain which may be wound upon a spring-roller O', (see the spring at O2 in Fig. 5,) and which blind O is provided at its free edge with a slat or other suitable enlargement O3,by which it will be stopped by suitable forks P, carried by the framing, and it is also provided at such edge with a ring or loop Q,Which may be automatically engaged by a hook Q at the upper end of the movable shelvingsection and may be caught by a hooked rod when it is desired to lower the blind to cover the lower fixed section of the shelving. This blind O, it will be noticed, is in line with the front edge of the fixed shelving-section A, and it can when the parts are in the position shown in Fig. 2 be drawn down to the base of the section A and be secured by a hook Q2,

. (see Fig. 1,) and thus serve to cover both the fixed and movable shelving-sections, or the blind O may be simply drawn down automatically by the movable shelving-section B to cover the space left vacant by the lowering of said section, as shown at the right in Fig. 1. This blind not onlyserves to exclude dust and to improve the appearance by hiding the space IOO IIO

provided for the shelving-section B, but it 4 tory to lowering it, its hook Q will engage the ring Q of the blind O and will draw the said blind down to the position shown at the right in said figure as the lnovable shelvingsection is adjusted to its said position. Manifestly a suitable molding R may be extended across in front of the shelving at the upper end thereof, or such part may be cased in any suitable way.

It maybe desirable to employ a stop-spring S, such as shown in Fig. 10, for holding the shelving-section from movement in either di`- rection except when forcibly moved past the said spring. This spring is arranged to yield under extra pressure and may be employed to hold the movable shelving-section in its lowermost position or at any suitable height against the action of the counterbalancingweight. The movable shelving-section may be found useful for storing away goods when not in season, such as winter goods in summer, and vice versa.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

In an apparatus substantially as described the combination of the shelves provided with slots elongated in the direction of length of the shelves, stay-rods extended through said slots, and shelf-sustaining portions on the stay-rods beneath the shelves substantially as set forth.
