DEVICE FOR FORMING BELT-LACING.

SPECIFICATION forming part of Letters Patent No. 544,177, dated August 6, 1895.

I Application filed February 16, 1895- Serial lie/538,603. (No model.)

resident of Washington, in the District of Golumbia, haveinvented certain new and useful Improvements in Devices for Forming Belt- Lacing; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to devices for bending wire to form belt-lacing for securing together the ends of a. strip of belting to produce a virtually endless belt. 5

It has for its object to simplify devices of this character and to increase their efficiency and diminish the cost of the devices, and also the time and labor required for the production of the lacing.

The invention consists in the construction hereinafter described and particularly pointed out. p

In the accompanying drawings, Figure 1 is a front elevation. Fig. 2 is a plan. Fig. 3 is a section on line 3 3 of Fig.2. Fig. 4 isasection of a modified form. Fig. 5 is a partial side elevation; and Fig. 6 is an isometric view of wire bent in form suitable for connecting the proximate ends of a belting-stri p by means of a straight supplementary wire shown in operative position, the belt being omitted. Fig. 7 is a plan of a modification. Fig. 8 is a section on line 8 8 of Fig. 7. Fig. 9 is asection on line 9 9 of Fig. 7. Fig. 10 is a sectionof a modified detail.-

. In Figs. 1 to 3,inclusive,a portion ofwire belt -1acing 2 is shown, formed in and by means of the improved device.

Numeral 1 indicates a bench or like solid 4:) support, and 3 denotes bolts for securing the device thereto.

As shown in Figs. 2 and 3, the device comprises a front plate 4 and a back plate 5, each provided with studs or pins, and with a main 5 separating or spacing block or plate 6 and subsidiary spacing-plates 7 8 indicates thumb-nuts and bolts for suitably holding the several parts together, and 9 indicates washers.

The separating-plates 7 are preferably provided with notches 7 to adapt them to be placed over the bolts between plates 4 and 5.

The use of the spacing-plates is to vary the operative distance between the plates 4 and 5 to provide for the manufacture of lacing of varioussizes. Any desired number of these platesmay be employed, or the main block 6 may be made of a sufficient size, and the subsidiary plates dispensed with, substitute blocks 6 of suitable size being provided as may be suitable for each desired size of-beltlacing. It'isfurther obvious that the use of separable plates or blocks, such as 6 or 7, is

not essential, and that the operation of the device adapted for a given size would be unaffected if the article was made entire without the described means of adjustment.

The rear plate 5 is provided with short studs or pins 5', arranged in pairs, as shown, the members of said pair being separatedby a distance slightly exceeding the diameter of the wire to be bent therein. The distance between the pairs will in each case be made according to the desired distance apart of the loops ofthe belt-lacing.

The front plate 4 has a series of studs 0 posts 4', each having an arm 4" at about its mid-height, and having a distance from the edge of the plate a little larger than the diameter of the wire used in making the beltlacing. Both the free end of the stud or post and of its arm is by preference slightly enlarged to prevent wire slipping off from the same, as will more clearly appear in the description of the operation to be made hereinafter.

The posts 4' are preferablymade shorter than the pins or studs 5, and of the dimen- 'sions substantially as shown, or such that the head of each'post 4' extends above and near to the upper surface of the wire under operation.

10 indicates an eccentrically-pivoted wireclamping device, but the particular construction of this device is not essential.

In operation an end of the wire is secured by the clamp described, or in any suitable way, and the wire is then bent and inserted between two studs 5'. The part thus manipulated remaining in place, the wire is slipped under arm 4 and bent up and about it where it remains until the operation is completed. The wire is next inserted between the two opposite studs 5 and then bent about the second one and then about the first stud of the next pair, as indicated at 2' in Fig. 2. This manipulation is repeated until as many loops are formed as desired, whereuponthe wire is suitably cut from the main length, if necessary, and the lacing is removed from the studs and its free ends suitably bent. The product is then complete and its bends 2" are ready to receive the usual tie-wire 12 when applied to belts in a well-known manner not necessary to further describe.

In practice the plates 4 and 5 can be cut from sheet metal, and the studs formed thereon by stamping or punching, but itis not essential that separable plates be used nor that the studs be integral therewith.

The use of the particular pins or studs 4' and 5 is not essential.

Suitable notches or slots, such as indicated at 13 in Fig. 5, for holding the wire in combination with a horizontal arm 4" or an equivalent means for forming a wire loop will be suliicient, and will operate substantially as elsewhere set forth in connection with the studs or pins. In Fig. 5 is shown a portion of a plate or equivalent in which pins are dispensed with.

In Fig. 1 numeral 6' indicates bars, and 7" spacing-strips, all of which may .be made of wood, if desired. Pins can be driven into these and arranged to. operate substantially as above described,

It is obvious that the device, exclusive of locking and fastening mechanism, could be cast in one piece.

In Figs. 7 to 10, inclusive, is shown another modification, in which 14 denotes a strip or plate of sheet metal suitably formed bystamping or otherwise to provide wire-holding recesscs 13.

16 denotes posts provided with horizontal arms 17, formed of sheet metal in like manner. The arms 17 serve the same purpose as those denoted by 4 in other figures. More than one may be provided adjacent to each recess 13 to provide for making loops of various lengths, and this mode of securing the said result may be combined with or substituted for means of adjusting the front and back plates hereinbefore described.

18 denotes nails orscrews for attaching the strips, having the form described, to a supporting block or blocks.

The arms 17 may be formed in separate pieces, each piece to be situated opposite a recess 13, as indicated in Figs. 7 to 9, inclusive, or several corresponding to several of said recesses may be formed of a continuousstrip of sheet metal, as indicated in Fig. 10.

The construction, as shown in Fig. 7, provides longer wire-holding recesses 13 than produced by the studs or pins shown in Fig. 1, though 'the latter might be suitably shaped or extended to afford wire-holding recesses of the same length. The advantage of such long recesses is that they hold the two members of the loop formed therein securely in a plane transverse to the length ofthe lacing, and in position substantially such as indicated at 2" in Fig. 6, and thus prevent their assuming or too nearly approaching a situation in the same plane lengthwise of the lacing.

Y The means for attaching the device to a bench or table is not essential, and it may be held in a vise or in any usual or convenient manner.

Having thus fully described my invention, what I claim is- 1. In a device for forming belt-lacing, pins or the like arranged and constructed to provide at suitable intervals wire holding spaces, in combination with stationary arms 4" situated each opposite a wire holding space and in a plane transverse to the length of said space, substantially as set forth.

2. In a device for forming belt-lacing, pins or the like arranged and constructed to provide at suitable intervals wire holding spaces,

in combination with stationary arms ysituated each opposite a wire holding space and in a plane transverse to the length of said space, and means for varying the distance between the arms and spaces, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib ing witnesses.

CHAS. K. JUDSON.
