' 2 Claims.

This invention relates to the splicing 'of laminated belts such as those made of plies of rubber and fabric and has as its general object the provision of a gauge board or device to facilitate the marking and cutting of the various plies of the belt preparatory to making the splice.

modes so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective View of a gauge board and straight edge constructed in accordance with this invention, one end portion of the board being omitted;

By way of illustration, but not limitation, the I present invention is particularly well adapted for use in preparing the ended a belt for making the splice illustrated and described in Patent No. 1,996,529, issued April 2, 1935.

In the making of'a splice of that type the several laminations of the belt must be cut and peeled off predetermined different distances from its ends in accordance with a table or set of instructions issued by the manufacturer of the belt. The use of such tables and instructions entails making numerous measurements and as a result is quite time consuming. In addition the need for making repeated measurements is a fruitful source of trouble due to the likelihood of inaci along both its Side edges are shoulders 6 and 1 curacies in making the measurements. a

It is, therefore, the purpose of this invention to provide means by which the marking and cutting of the belt ends is greatly facilitated to the point of materially speeding up the operation and reducing, if not eliminating entirely; the possibilities for error.

In past practice it has been the custom of the workmen to merely clamp the belt to the top of a bench by means of a C clamp or the like and then lay out the locations of the successive cuts. While clamping the belt to the bench facilitated peeling off the'cut end portions of the successive plies of the belt it was at best a makeshift method. It is, therefore, a further object of this invention to provide a gauge board to which the belt may be clamped in a predetermined position and by which the belt is not only held against endwise movement, but also against lateral displacement during the peeling off of the successive laminations.

Referring now particularly to the accompanying drawing in which like numerals indicate like a parts, the numeral 5 designates a fiat board, pref- With the above and other objects in view which I erably of wood, of a width great enough to accommodate the widest belt for which the device is designed and of a length to accommodate the longest splice.

Extending up from the top face of the board adapted to have a side edge of a belt in position on the board engaged thereagainst. One end portion of the board has its top face provided with a plurality of parallel crossed diagonal reference lines 8. The angle of these lines is determined by the angle recommended by the belt manufacturer for the angle at which the plies are to be out. In the present instance the lines form 45 angles to the shoulders B and I.

The innermost set of references lines 8 is indicated by the legend 4 Ply, the next by, the legend 5 & 6 Ply, the next by the legend '7 Ply and consecutively thereafter as clearly shown.

The location and spacing of these reference lines bears a predetermined relationship to other reference marks or indiciadesignated generally by the numeral 9 and located on the side portions or shoulders of the board.

These reference marks 9 are duplicated at opposite sides of the board and are directly opposite each other as shown. Specifically they consist of transverse lines designated A, B and C and a plurality of longitudinal lines 10 and II which define longitudinal rows designated by the numerals 4, 5 and 6, these numerals having reference to the number of plies or laminations.

Beyond the point I2, where the longitudinal lines It] and II terminate, the shouldered side edges of the board have cross lines or marks I3.

The end of the board, opposite the diagonal reference'lines 8, is equipped with a clamp H by which a belt may be clamped in place on the board. The clamp secures the belt against longi-' edge or blade I6 extends diagonally at 45 across the face of the board and across any belt in position thereon.

In the use of the device the procedure is as follows:

Assuming the belt has five plies, it is positioned on the board as illustrated in Figure 3 with its end on the diagonal reference line 8 designated by the legend 5 & 6 Ply. The shoulder 6 or I against which the side of the belt is brought depends upon which of its'two ends is being worked on, one shoulder is for one end of the belt, and the other shoulder is for the other end.

Having thus properly positioned the belt, the clamp 14 is tightened whereupon the belt is secured against displacement on the board. Thereupon the 45 T-square I5 is used to strike off a line [8 diagonally across the face of the belt which determines where the belt is to be cut off diagonally across its full thickness.

Thereafter the T-square is brought down to its position shown in Figure 3 at which a refer- For belts of four laminations the cross marks in the row 4 are used to designate the locations of the cuts, and for six-ply belts the marks in the row 6 are used. For belts of seven or more plies the marks in the number 6 row are used for the third, fourth and fifth plies and for the remaining plies the marks I3 are used.

Inasmuch as this invention is concerned solely with marking the various laminations of the belt as required in a minimum of time and with maximum assurance against error and not in the making of the splice itself, this latter oper- V 'ation need not be described.

However, for a description thereof, reference may be had to the aforesaid Patent No. 1,996,529.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art, that this invention materially simplifies the preparation of the belt ends for splicing Where the belt is composed of a plurality of laminations which must be cut off in stepped relation and at predetermined distances from the ends thereof.

What I claim as my invention is:

1. A device for facilitating the splicing of laminated belts where the several laminations must be cut and peeled ofl predetermined different ence mark I9 on the head thereof is in line with the cross mark A. The top surface of the belt is then marked at the front of the straight edge to designate the line on which the top ply is to be cut and from which line this top ply is to be peeled off.

At the same time, the back edge of the straight edge enables marking a diagonal line across the face of the belt which corresponds with the mark B and indicates the point to which the top lamination is curled back as shown in Figure 2.

As will be readily appreciated this follows from Q distances from the end of the belt, comprising: a flat board; a shoulder extending along an edge of the board and adapted to have one side edge of a belt engaged thereagainst; a plurality of reference lines extending diagonally across the board from said shoulder to indicate the proper position of a belt on the board with reference to the number of its plies; other reference marks on another portion of the board; and a straight edge having a head engageable with a side of the board, said straight edgev forming an angle with its head equal to the angle said reference lines form with the shoulder and being positionable by reference to said last designated reference marks to properly and quickly locate the points at which the several plies of the belt are to be cut in itspreparation for the splice;

2. A device for facilitating the splicing of laminated belts where the several. laminations must be cut and peeled off at predetermined difis curled back to the line indicated by the mark the longitudinal lines l0 and H, and designated by the legend 5 referring to the number of plies in the belt, another line is scribed across the face of the third lamination or layer to be followed by a cut made on this line and a peeling off of the third layer from this line to the end of the belt. The fourth lamination is thereby exposed and the process is repeated using the point l2 as the indication at which theline of the cut is to be located. The fifthlamination, being the only one left extends to the end of the belt defined by the previously made line Ia.

ferent distances from the end of the belt, comprising: a fiat board, a shoulder extending along one side edge of the board and adapted to have one side edge of a belt engaged thereagainst; parallel reference lines extending diagonally across the board from said shoulder; said reference lines indicating the proper position of a belt on the board with reference to the number of its plies; other reference marks on another portion of the board spaced from said diagonal reference lines and bearing a predetermined-relationship to said diagonal reference lines; 'a straight edge having a head disposed at an angle thereto corresponding to the angle said diagonal reference lines make with the shoulder whereby said straight edge may be held in a positionextending diagonally across a belt on the board with the straight edge parallel to said diagonal reference lines; said straight. edge being positionable with reference to said last namedreference marks to so locate the same 'as to enable marking the successive plies of the belt atthe points at which they are to be cut; and a clamp on the board for clampingthe beltto the board.
