Description
UNITED STATES PATENT OFFICE.
GEORGE J. KUHN, OF ST. LOUIS, MISS OURI.
OILABLE SASH-CORD GUIDE.
SPECIFICATION forming part of Letters Patent No. 418,030, dated December 24, 1889.
Application filed March 30, 1889. Serial No. 305 ,47'7. (No model.)
To all 1072,0112, it may concern.-
Be it known that I, GEORGE J. KiiHN, a citizen of the United States, residing in the city of St. Louis, State of Missouri, have invented a new and useful Improvement in Sash Cord Guides, of which the following is a specification.
The object of my invention is to furnish means by which the axle of the sheave may be oiled at any time without removal from the frame or housing; and my invention consists of certain features of novelty to be hereinafter described, and then particularly pointed out in the claim.
In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 is a perspective view showing a portion of a window-frame or other frame to which my device is applied,part of the frame being broken away. Fig. 2 is a face view of my device. Fig. 3 is a side view.
The object of my invention is accomplished in a very simple manner and without holes in the housing, and with no ribs or any complicated oilconductors, as heretofore employed, and which, on account of clogging of the oil, accumulation of dust, swelling of the wood, &c., soon render the device worthless.
To these ends my device consists of the housing A, in the shape of a flattened ellipse, which is provided with the slot 0 for the sheave, and screw-holes B in the end lugs A for the reception of screws, side flanges F, that extend from the sides of the slot rearwardly, and swellings, enlargements, or protuberances G and H on the outer sides of the flanges, having between them at each side of the face plate recesses or cavities I. The enlargements G and II are about an inch in width at the ends and extend from both the upper and lower ends of the flanges F to within about one-quarter of an inch of each other upon the front or face plate and within twice that distance at the rear, according to the size of the pulley D.- By the aid of such'small oil-cans as may be found. in every household having a sewing-machine, oil may be deposited through the recesses between the enlargements directly onto the axle very great degree its strength and durability.
The enlargements G and H may be cast upon either the inside or outside of the flanges; but I prefer the latter, as this leaves no space for the rope to slip into between the flanges and the sheave in the event of the ropes displacement by a too rapid raising of the sash. This arrangement forms .a perfect oil-box, which can be readily cleaned by the use of a small rod or piece of wood, as there are no obstructions back of the recesses and axle to prevent the dislodgment of any accumulated matter.
I do not pretend to oil the pulley or sheave itself, but the axle thereof, and for the reason that, unlike most guides whose lower sheave revolves upon a stationary and ordinary iron pin riveted upon the outside of the flanges, mine is shrunk by the aid of heat (or otherwise firmly attached, as shall be deemed best) upon a steel axle whose ends revolve in bearings fully a quarter of an inch in thickness, owing to the addition of the enlargements G, forming a simple and thoroughly practical device for the purpose set forth.
I am aware that it is not broadly new to introduce oil into sash-cord guides for the purpose of lubricating the same. Neither is it new to have the sheave and axle in one piece. 7
Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
An integraily-cast sash-cord guide consisting of a flattened elliptical housing having flanges extending on each side of the pulley, opening rearwardly, enlargements orswellin G and H onthe outer side of each flange, andthe fronts of which are flush with the front of the housing, between which swellings are formed,
open-sided recesses extending rearwardly, halves of the holes, so that the outer ends of and a pulley having an axle Whiohmay be the bearings are open at top, substantially lubricated from said recesses, the ends of said as set forth.
axle passing through and journaling in bear- GEORGE J. KllHN. ings consisting of holes in the flanges and lVitnesses: conoavities in the upper edges of the lower J. S. ENSOR,
enlargements that are flush with the lower CHAS. JONES, Jr.
