UNITED STATES PATENT OFFICE.
OLIVER S. GARRETSON, OF BUFFALO, NEW YORK.
EXTENSION-TABLE SLI DE.
SPECIFICATION forming part of Letters Patent No. 229,037, dated June 22, 1880,
` Application filed December 29, 1879. i
To all whom it may concern Be it known' that I, OLIVER S. GAEEE'rsoN, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Extension-Table Slides, of which the following is a specification, reference being had to the accompanying drawings. Y
This invention relates more especially to that class of table-slides in which the wings and grooves are constructed in the form of a cross laid on its side; and it has for its object to render such slides more\durable and more easy and uniform -in their operation.
My invention consists, to that end, of a cross-slide constructed with two angular ribs arranged respectively on the upper and lower side of the slide in the angle of its wings, whereby the sharp edges on the wooden slidebars are avoided and the operation of the slides is rendered more easy and uniform.
In the accompanying drawings, Figure l is an end view of my improved slides. Fig. 2 is an end view of one of the slide-bars. Fig. Sis a similar view of an ordinary cross slide-bar. Fig. 4 is a perspective view of one of my improved metallic slides. Fig. 5 is a horizontal section of the slide-bars provided with. my improvement.v
Like letters of `reference refer to similar parts in the several figures.
A represents the wooden slide-bars, and B the metallic slides, secured in the grooves of thc slide-bars by fastening-pins c. The slides B and the grooves 'd of the slide-bars are constructed in the form of a cross laid on its side, the wings ot' the slides being arranged at right angles to each other, or at any other suitable angle, as may he preferred.
The wings e c of the slide, which are stationary within the groove of the slide-bar, are made somewhat thicker than the wings f f of the same slide, which are movable within the g; `ove, so that the wings e e can be tightly driven into the groove of" one slide-bar, while the wings ff will work freely in the groove of the opposite slide-bar.
g g are angular ribs arranged in the angles formed by the wings e and f on the upper and lower sides of the slides, the ridge or apex of 5o the ribs g being in the plane of Contact ofthe two adjacent slide-bars. The angle of the rib g is preferably arranged to correspond with the angle of the wings ef, so that the grooves for the reception of the ribs g can be formed in the slide-bars by the same cuts which form the grooves for the reception of the wings ef, as indicated by the dotted lines in Fig. 2. The ribs g take oli' the sharp edge h of the ordi` nary cross-slide, (represented inFig. 3,) which edge is very thin and sharp, and frequently becomes broken oft' or bruised or bent in making or handling the slides.
When a downward pressure is applied to the ordinary slidebar the straight incline, terminating in the edge h, tends to wedge the bars together, thereby interfering with the free movement of the slides, while in myimproved slide this thrust is received and eouuteracted by the rib or shoulder g, and the wedging or cramping of the slides is thereby entirely avoided.
By the use of my improved slide the free and unobstructed movement of the bars is insured, and the edges of the grooves are made so blunt that no splitting oi or bruising of the edges can occur, thereby rendering the slides very durable.
As shown inl Fig. 1 1-, aportion of the running or thin Wings f of each4 slide is out ofi' to form a shoulder, which strikes against the stop-pins t', secured in the grooves l of the slide-bars, and arrests the movement of the slides in the ordinary manner.
I claim as my invention- A table-slide made in the form of a cross,
'and constructed with ribs g on its upper and lower sides in the angles of its wings, substan tially as set forth.
OLIVER S. GARRETSON.
