Application filed February 29, 1904. Serial No. 195,981. (No model.)

T0 (0 'IJI/MTIII/ 1115 may con/(smut:

Be it known that .1, Dr] LAsKI T. Cnnuoxs, a citizen of the United States, residing at llorncllsville, in the county of filbQUlJGll and Mate of New York, have invented a new and useful Belt-Splice, of which. the following is a specilication.

This invention relates to belt-splices.

The object of the invention is in a thoroughly feasible and practical manner to obviate the presentation of abutting edges extending longitudinally or transversely of the belt, thereby greatly to strengthen the union between the belt ends and to cause the abradingsurface at the point of juncture of the said ends to cut smoothly and without the formation of grooves in the work.

As is well-known, the ordinary procedure of securing together the abutting ends of a sandpapenbelt, such as is used in furniturefactories, is to bring the ends together and hold them juxtaposed by a flexible backing or reinforce pasted to the back of the belt and covering the meeting edges thereof. The abutting edges may be disposed at right angles to the length of the belt or obliquely thereto; but in either event there are presented straight edges which if loosened from their backing or reinforce under the operation of the belt will result in the destruction of the joint and also the formation of grooves in the work which will tend to mar the same. Furthermore, where a rupture in the juncture between the belt ends occurs the union will gradually be destroyed, for the reason as the belt revolves around the driving wheels or pulleys at each revolution there is a further disruption or separation of belt from its backing.

The above objectionable features are in the present instance positively eliminated by providing the belt ends with the tongues, the perimeters of which are formed throughout on curved lines, the tongues on one end being the counterpart of those on the other, so that when interlocked a neat, finished, and strong ioin t will be provided. As all of the edges of the tongues are on curved lines, it follows that when the belt ends are assembled there will be no straight abutting edges extending longitudinally or transversely of the belt, and thus the uneven dressing of lumber will be obviated, and a positive retention of the interlocked relation of the tongues will be assured. The tongues are held interloclu-id and against separation under longitudinal strain through the medium of a flexible backing, preferably of textile fabric, which is glued or cemented to the back of the belt and bridges the point of juncture between the two ends. The arrangement of the present belt-splice is such that even under long continued use there will be no tendency of the interlocked tongues to separate from the backing, and thus a thoroughly effective and du able abrzuling-belt is effected.

\Vith the above and other objects in view, as will appear as the nature of the invention better understood, the same consists, generally stated, in the novel forms of belt-splice hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and. in which like characters of reference indicate corresponding parts, there are. illustrated two forms of embodin'ient of the invention, each capable of carrying the same into practical operation, it being understood that the invention is not to be limited to the precise arrangements shown.

lln the drawings, Figure 1 is a view in elcvation, partly in section, of an al.)radingbelt, showing the splice disposed transversely of the length of the belt. Fig. 2 is a view in elevation, exhibiting a portion of a belt in which the splice is disposed obliquely to the length of the belt. Fig. a view in transverse section through the belt.

The belt (designated generally 1) is made preferably from sandpaper, although any obliquely thereto preferably at an angle of about forty-five degrees; but whatever their angle of disposition be with relation to the length of the belt there will never be formed straight abutting edges that will tend to groove the work over which the belt passes. The positive holding of the tongues against separation under longitudinal strain is secured by constructing them on the lines of a double ogee curvethat is to say, on the lines of a figure formed by uniting the upper ends of two ogee curves with their bulges disposed in opposite directions, the perimeters of the tongues being formed throughout on curved lines, so that when a head of one tongue is p0- sitioned between the necks of two adjacent tongues there is to all intent and purposes a dovetailed joint formed, the holding properties of which are well known, but without the presentation of straight abutting edges that will be present in the ordinary dovetail joint.

In addition to the advantages enumerated in this form of belt-splice the tongues by reason of the manner in which they are interlocked will greatly increase the strength of the j uncture between the belt ends and will cooperate with the backing in preventing their separation in use.

Having thus fully described my invention, what I claim is 1. An abrading-belt having its ends united by interlocked tongues, the perimeters of which are formed throughout on curved lines.

2. An abrading-belt having it ends united by interlocked tongues, the perimeters of which are formed throughout on curved lines, and a reinforce secured back of the tongues.

3. An abrading-belt having its ends united by interlocked approximately double ogeeshaped tongues.

4. An abrading-belt having its ends united by interlocked approximately double ogeeshaped tongues, and a reinforce secured back of the tongues.

5. An abrading-belt having its ends united by interlocked approximately double ogeeshaped tongues, the heads of which are disposed in the direction of the length of the belt.

6. An abrading-belt having its ends united by interlocked approximately double ogeeshaped tongues, the heads of which are disposed in the direction of the length of the belt, and a reinforce secured to the back of the belt and bridging the splice formed by the tongues.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
