CORD-ADJUSTER.

Specieation of Letters latent.

Patented July 9, 1918.

Original application led May 23, 1916, Serial No. 99,310. Divided and this application filed. March 18, 1918. Serial No. 223,059.

To all whom it may concern:

Be it known that I, LESTER L. KELL, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Cord- Adjusters, of which the following is a speciication containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. Y

My invention relates to improvements in cord adjusters, and this application is a division of my application for improvements in swings, filed May 23, 1916, Serial Number 99,310.

The object of my invention is to provide a cord adjuster which may be produced at a relatively low cost; which offers relatively great resistance to cord movements; which requires relatively little eifect to effect an adjustment of the cord and which is practically unbreakable and possessed of pleasing appearance. y

My improvements consist in the novel construction, arrangements and combinations of elements which ,will be fully, clearly and concisely set forth in the following specification, denitely pointed out in my claims and illustrated by the 'accompanying drawings, in Whichi Figure l is an elevation of a cord adjuster embodying my invention.

Fig. 2 is a view similar to Fig. l taken from a diametrically opposite view point.

Fig. 3 is a vertical sectional elevation taken on the line3w-3 of Fig. 2, with the cord omitted.

Fig. 4 is a vertical sectional elevation taken on the line 4--4 of Fig. 3 and showing the arrangement of the cord, and

Fig. 5 is a sectional plan taken on the line 5 5 of Fig. 3 showing the arrangement of the cord.

Referring by numerals to the drawings 6 designates the body of the adjuster, which is preferably formed out of a single piece of wood and of spherical shape as shown.

Mechanically and functionally such designated material and shape are not essential, as obviously, metal, ceramics, glass and so forth may be substituted for the wood, and likewise the body may be formed circular, square, polygonical or oblong, sectionally, in a plane at a right angle to the trend of the cord and of square, oblong,

elliptical, oval, conical or pyramidall exterior. Inasmuch, however, as the adjuster is designed for use along the length of a swing suspension cord or rope I `nd the spherical exterior, which presents no angles, to be most comfortable to manual grasping andl the least likely to inflict or suffer injury.

As best shown in Fig. 3 there is formed in the body 6, and diametrically thereof along its Vertical axis (when used on a vertical cord, as in a swing, or its horizontal axis when used on a horizontal cord such as a clothes line) a bore or opening 7, open at the surface 8 of the body and extended to a point therewithin between the center of the body and a surface point diametrically opposite the open end just recited, and of a dimension capable of receiving a cord length doubled upon itself, as shown in Fig. 4. From the said point within the body, that is, from the innermost end of the bore 7, and leading to and open at the surface S at a point diametrically opposite the open, outer end of the bore 7, there is a bore 9, which is of a size less than the bore 7, and capable of receiving only a single cord length, as shown in Fig. 4.

f As best shown in Fig. 3 there is a bore or opening 10, open at the surface 8 at a point, intersected by a line drawn through the open ends of the bores 7 and 9 and belting the body, and which bore 10 opens into the bore 7. As shown in Fig. 5, the bore 10 is of a transverse dimension capable of receiving a cord length doubled upon itself.-

Alining with thelongitudinal axis of the bore l0 andextending into the body 6 from the bore 7 to a point inside the body is a bore 11, of a size capable of receiving only a single cord length and from the outermost end of the bore 11 open to both the bore 11 and the surface 8 is a bore 12 of a size capable of receiving a knotted end of the cord.

In the surface, belting the body 6 and intersecting the bores 10 and 12 is a groove 13 whose depth is preferably less than the sectional dimension of the cord.

In the formation of the bore l2 of a greater dimension than the bore 11 a shoulder 14 is provided which serves as an abutment for the knotted end of the cord to hold the cord against movement in one direction in the bore 12, and likewise by forming the bores 11 and 7 and the bores 7 and 10 in right angular relationship the points 15, 1G and 17 are provided within thel body and the points 18 and 19 at the surface, which serve with the surface of the groove 13,. to resist corda movements.

The threading of the cord may progress from either of its ends Yand for the-purpose of this illustration I will describe it asproceeding from the end 2O which leads to an oi'feiheadl suspension means (not shown) and as 4employed ina swing.

rI his end 20 of the cord is inserted downwardly through the bore 9 and being sectionally of the approximate dimension of the bore makes such a fit therein vespecially at the surface surrounding the bore as to preclude the possibility of pinching the fingers, skin or garments ofa person using the swing. From'the bore 9 the cord end is passed downwardly through the bore 7 to engageover the pointv A15, thence through the bore 10v to the 'surface 8, where it engages over the point 1S and thence belts the body, occupying the groove 13. The cord is then threaded again inthe bore 10 from the surfaceSinwardly and engaged over the point 19, thence from the inner end aof the bore 19 is turned downwardly and extended through thel bore 7 and engaged over the point 16, thence outside the bore 7 where it is doubled upc-n itself to vform the bight 21,

l as shown in Fig. 4; and again extended into thebore 7 to the'bore 11, engaging over `the point 17 and thence through the bores 11 and 12, whereupon the cord end is knotted,

as at`22, and'retraoted or drawn so that the knotted end is seated in the bore 12 against the shoulder 14.

It is obvious that the cord is drawn over a number of points both on the exterior and interior of the body of the adjuster `and that it also engages throughout a considen able 'portion of v'its length the exterior surface of the adjuster body, and that regardless of the shape of such exterior surface considerable surface friction is provided. However, I prefer, as stated, to employ a groove which sectionally conforms to the cord to increase the surfaceI friction area'as well as to act as' a lmeans to hold the cord against .grotesque irregularity around the adjuster body.

It will be readily apparent that Vupon the Y Iapplication of tension to the cord end 20 through the several bores.

Having thus described my invention, what I claim as new therein and desire to 4secure by Letters-Patent is:

1. A Vcord adjuster ycomprising' va body having right angle openings therethrough and a groove belting the adjuster and interL seeting said openings.

2. A cord adjuster formed from a single, solid piece of material and providedv with relatively angular bores 'therethrough and a continuous exterior groove belting the body and intersectingl certain ofthe bores.

A cord adjuster lcomprising a'body having means within its interior for holding a Cord end, a pair of openings leading to the exterior of the body and substantially aliiied with thel tension line of a cord to'be extended therethrough and 'an opening within vthe body communicating with the 'pair of openings and'leading to the exterior'of the body at a point on the exterior removed' from the" intercoinmunieatin g within the adjuster body and certain of said bores'havingwithin their lengths diametrijcal reductions 'substantially as shown and for the purposesstated.

A cord adjuster formed from a single,

solid piece ofinaterialfand provided with bores open at the exteriorof thebody and intercolnniunicatingv within 'the adjuster body, *certain of 'said bores having within their lengths diametrical reductions and there being a groove beltiiigk thev exterior surface of the bodyI and' Aintersecting certain of said bores.

6.*In 'combinatioirwith a" spherical body provided withbores open atthe exterior of thebody andiiiiteroominiinicating within the body, certain of 'which' 'bores having `within their lengths diametrical reductionsand a groove belting the 'exterior'suiface Aof the body and intersectingfat'fleast one of said bores, a cord having ajknotted end'seated in one of tlieboifesaiicl-lield against movement by reason o'f one of the diametrically reduced portions of the bore, said cord being doubled in vone 'of the bores and extended around thev body in said groove, said Vcord being doubled in a second bore and'provided with a bight outside 'said second boreand said cord extended through a third bore to' project from the'body.
