SLIDE FOR EXTENSION-TABLES.-
SPECIFICATION forming part of Letters Patent No. 434,271, dated August 12, 1890. Application filed Apn'l 5, 1890. Serial No. 346,684. (No model.)
To all whom it may concern:
Be it known that I, JOHN DAVID HECKMAN, a citizen of the United States, residing at Carthage, in the countyof J eiferson and State of New York, have invented certain new and useful Improvements in Slides forEXtension- Tables; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to certain new and useful improvementsin eXtension-tableslides and it has for its object to provide a simple, cheap, and durable slide which will enable the table to sustain a great amount of weight.
The novelty of the invention resides in the peculiarcombination, andin the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the claims.
In the drawings, Figure 1 is a plan view of an extension-table with my improved slide attached thereto. Fig. 2 is a detail perspective view of a portion of one of the slides. Fig. 3 is a longitudinal section on the line 00 as of Fig. 2, and Fig. 4 is an end view of one of the slides when closed.
Like letters of reference indicate like parts throughout the several views.
Reference now being bad to the details of the drawings by letter, A designates one half the slide, and as bot-h halves are alike a description of one will sufiice. I
Theparts composing theslide may be formed of any suitable material-such as wood, iron, or part wood and part iron, as preferred. Each half of the slide is composed of a suitable number of parts. (I have shown five in this instance.) The central one of the parts is substantially T-shaped in cross-section, the rib portion Z) serving as a guide for the adjacent portions. This centralportion has upon each side ofthe said rib a slot 0, which is countersunk or hasa portion below the upper surface, as shown at d, which serves as aguide for the guide-blocks hereinafter described. These slots are arranged so that the ends extend past each otherin opposite directions, as shown in Fig. 1. The two pieces 0 and D one upon each side of the central piece-are similar to the said central piece, except that they are reversed-that is, they are turned bottom side up, with the rib portions extending in a direction to the rib portion of the central piece, the said ribs serving to guide the three pieces, as will be readily understood.
E are the outer pieces of the slide. Each is formed with a longitudinal slot cl, and is substantially L-shaped in cross-section, as seen in Fig. 4. The flat portions ride upon the coincident portions of the pieces 0 and D with their slots coincident, the vertical portions serving as guides to keep the parts in their proper relations. These outside pieces are formed with ears or lugs e, perforated, as shown, for the reception of the screws or other securing means employed to secure them to the outer fixed portions of the table-top. Each piece carries coincident with each slot a guide-block F, which may be of any suitable material, but preferably of metal, held to the piece by which it is carried by a bolt, rivet, or other analogous provision f. 7 These guideblocks are arranged to slide within the slots of the several pieces, and are seated within the countersunk portions of the slots, so that they will be flush with or below the outer face of the piece, as shown. These guide-blocks serve also as stops to limit the longitudinal movement of the parts upon each other. The halving of the parts together, as shown, gives great strength with a minimum of material. The ribs, in connection with the halving together of the parts, provide not only for the perfect parallelism of the parts in operation, but prevent the parts from wabbling-that is, moving in a plane at right angles to their length, which is an important feature.
- A table -slide constructed as above described has proved to be very strong and durable and very easy of extension or contraction, there being very little friction, and the parts being at all times kept in their proper relative positions very little power is required to operate them.
What I claim as new is- 1. The extension-slide described, eonsistin g of the central piece substantially T-shaped in crosssection, the adjacent reversed pieces also substantially T-shaped in cross-section,
.the outer pieces substantially L-shaped in cross-section and formed with perforated lugs, all of said pieces being formed with longitudidinal slots, and the guide-blocks carried by the said pieces and alternately and oppositely arranged and working in the slots, substantially as shown and described.
2. The extension-slide herein shown and described, consisting of two like halves, each half composed of a plurality of parts, the central one of which is T-shaped in crosssection and having upon each side of its center riba countersunk slot, said slots arranged with their ends extended past each other in opposite directions, the side pieces C and 1), similar to the central piece, but reversed, the outer pieces E,substantially L-shaped in crosssection and each formed with longitudinal slot and lugs e, the guide-blocks F, carried by each piece and working in the slots and inversely arranged, and the rivets f, substantially as shown and described, and for the purpose specified.
In testimony whereof I aifix my signature in presence of two witnesses.
