Specification of letters Patent.
Patented July 4, 1922.
Application filed December 5, 1921. SerialNo. 519,881.
To all whom it may concern:
Be it known that I, GEORGE L. NoLL, a citizen of the United States, and a resident of Madison, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Antifriction Skids, of which thefollowing is a speciiication.
One of the objects of this invention is to provide an adjustable loading and unloading skid having means by which heavy boxes, barrels, crates and similar articles may be readily and conveniently handled.
Another object is the provision of means consisting of rolls, horizontally and angularly j ournalled in bearings formed in metal channel plates fixed in the skid bars.
A third object is the means provided by which the skid bars may be adjustably spaced to accommodate and guide cylindrical articles passing between the bars.
Another object is to provide means by which a number of skid bars may be connected at their ends to form a skid run of any length.
These and other objects are attained by the novel construction and arrangement of parts, hereinafter described and claimed in the annexed specification and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a plan view of a pair of skids.
Figure 2 is a fraginental side view,brokeu away and showing means for connecting one section with another.
Figure 3 is a sectional view of the skids.
Figure 4c is an enlarged sectional view of a single skid, cross bar and clamping means.
Referring to the drawing in detail, the numeral 5 indicates one of a pair of wooden skid beams, to the top of which is secured by bolts 6, a metal channel strip 7 fabricated longitudinally into angular bends having grooves 8 and 9.
Openings forming bearings are provided through the side walls of the grooves 8 and 9 adapted to receive pint-les 10 and 11 on which the rolls 12 and 13 are rotatably mounted.
At the upper end of the metal strips are extending ends 14: bent downwardly forming hooks 15 adapted to engage in stake holes formed in a wagon body, and are also adapted to engage in slots 16 provided in the opposite end of the beams when more than one pair of skids are in use.
Transverse metal beams 17 are used to connect the skid beams and are formed with down curved center portions 18 to provide clearance for barrels or other cylindrical objects when passing over them.
Trough shaped clips 19 are secured to the underside of the skid bars and are formed with tapered bottoms adapted to receive wedges 20, which acting between the tapered clip 19 and the underside of the bars 17, securely clamps the skid beams 5 to the cross bars, thus providing adjustment for handling articles of various widths and diameters.
From the foregoing it will be seen that a practical re-enforced and adjustable skid or conveyor has been disclosed, having means whereby the functional resistance. usually encountered in loading and unloading merchandise has been eliminated almost entirely and while certain preferred embodiments of this device have been shown and described it will be understood that changes in the form, arrangements, proportions, sizes and details thereof, may be made without departing from the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A skid comprising a pair of skid beams, cross bars connecting therebetween, means secured near the ends of said skid beams adapted to engage a clamping wedge, metal channel strips attached to the upper surfaces of said beams, a plurality of spaced rolls ro tatable in said channels, and hooks at one end of the strips adapted to engage oblong recesses formed through the other end of said strip.
2. A skid conveyor comprising a pair of beams, a plurality of rolls, metal strips reenforcing said beams, channels formed in the strips and means therewith for rotatably mount'ng said rolls, cross bars for adjustably spacing the skid beams, clamping means for holding said beams in adjustment, said means consisting of a tapered bottom clip secured to the underside of said skid beams and a wedge co-acting between said clip bottom.
3. A skid comprising a pair of spaced beams, metal strips, channels formed with the strips, a plurality of friction reducing rolls operable in said channels, certain of said rolls being arranged in horizontal position adapted to make contact with flat surfaces moving along the skid, and certain beams on which said metal strips are en- 10 I other rolls disposed angularly and contactgaged, and hooks integral with the metal able with cylindrical objects moving along strips and adapted to engage transverse slots said skid, and means for adj ustably spacing formed through the lower end of said strips 5 the skids. 7 and beams. v I
