MACHINE FOR CONNECTING WEBS OF FABRICQ.

SPECIFICATION forming part of Letters Patent N 0. 656,303, dated August 21, 1900. Application filed May 31, 1900, are No. 18,552. (No model.)

My invention has reference to machines for i connecting webs of fabrics together; and it consists of the improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

Heretofore it has been customary to connect two long webs of linoleum together so as to cause the end of one web to draw the beginning of the other web through the coloring-machine and drying-chamber by overlapping the two ends and sewing them' together by hand. This caused greatlo ss of time, and hence was objectionable in that it required the other workmen to remain idle until the sewing was completed, and, secondly, kept the apparatus out of operation for a considerable period.

The object of my invention is to overcome these objections by providing a suitable apparatus which shall enable the two ends of the Web to be temporarily united in a speedy manner and also capable of quick separation after the drying process has been completed and the printing operation to begin.

My improved machine may be incorporated with the machine commonly used for applying the coloring pigment to the back of the web or it may be used separately, as desired.

My improvements consist of a series of stabbing-knives which are caused to perforate the overlapped webbing, a series of former-jaws below the webbing to raise the webbing between every other pair of perforations, and a series of movable former-jaws intermediate of the lower former-jaws and located above the webbing, said last-mentioned former-jaw being adapted to be depressed so as to depressthe webbing between the raised portions, thus forming a series of upward loops and downward loops arranged alternately, through which is thrust a needle or rod which, in elfect, laces the two webs together. The apparatus may have spring-ac tuated lifting shoes or arms which permit the depression of the web under the action of the depressing former-jaw, but raise the web and needle clear of the lower former jaw when the pressure of the upper former-jaw is re moved.

My invention also comprehends various details of construction, all of which will be bet ter understood by reference to the drawings, in which-- Figure 1 is a front elevation, with part broken away and part in section, of a ma- ,chine embodying my improvements. Fig. 2 is a cross-section of same on line 2 2 with the perforating or stabbing blades and upper formingjaws elevated prior to operating upon the fabric. Fig. 3 is a similar section show ing the parts in position during the process of uniting the webbing. Fig. at is a plan view of the completed 'joint formed between the two ends of thewebbing. Fig. 5 is an elevation of the united webbing looking toward one edge.

A is an upper and L a lower frame between which the webs of fabric P P are caused to pass. The upper frame A is provided with a series of vertical guides B,in which plungers C are guided and adapted to a vertical reciprocation. Every alternate plunger is connected to a bell-crank lever D by a connect ing-rod d, and the remaining alternate plungers are similarly connected to a second set of bell-cranks D. The free arms of the bellcrank D are hinged to a horizontal 0perating= bar E, and similarly the free arms of the bellcranksD are hinged to a bar E. The ends of these bars E and E are respectively connected by links a 2 with the cranks F E, which are adapted to be rotated by handpower devices G G. By this means either set of plungers may be reciprocated at will. The lower ends of the plungers corresponding to the bell-cranks D are provided with heads H, on the ends of which are secured in parallel arrangement two pointed stabbingblades h h, which may be forced down to perforate the webs of fabric in parallel slits, as

shown at R in Fig. 4. Secured to the other ends of the other plungers operated by the bell-cranks D are heads K, which carry on their under sides the two depressing formerjaws K, each of which consists of fixed inward fingers k k, which approach but do not meet each other, the object of which is to depress the fabric intermediate of the two slits made by the stabbing-blades h. Similar formerjaws J, formed of fingersj j, are secured to the lower frame L and point upward between and below each pair of blades h and their head H, the object of which is to raise those portions of the webbing between the slits R which are below the heads H and alternate of the portions acted upon by the formerjaws K.

M shows a series of hinged lifting arms or shoes hinged to the lower frame at m and pressed upward by springs N of any suitable construction, the object of which is to raise the webs of fabric clear of the lower formerjaws J when the upper jaws and blades are raised, so as to cause them to travel free of said lower former-jaws.

The operation of my apparatus will now be understood. Applying this structure to the well-known linoleum-machine for applying coloring-pigment to the back of the web, the operation would be as follows: When the web P has almost passed through the coloring-machine and is still between the jaws of the machine above described, the beginning of the next web P to be treated is overlapped upon the end of the first-mentioned web, being placed either above or below, as may be desired, and the two webs in that relation bein g caused to pass into a position between the former jaws, as shown in Fig. 2. To facilitate this moving of the two webs into position, they may be temporarily connected at opposite edges by a couple of stitches T, Fig. 5. When brought to the position shown in Fig. 2, the hand-power G is operated and the stabbing-blades h it forced through the webbing, making a series of parallel slits R. The hand-power G is next operated and depresses the former-jaws K, which depress every alternate part of the webbing between the slits R, while the lower former-jaws J raise the other alternate parts. The spring-arms M are also depressed by the action of the former-jaws K. The stabbing-blades h are then raised clear of the webbing and the parts are in the position shown in Fig. 3. This insures a longitudinal passage 19, extending transversely through the webbing below and above alternate portions of the, said webbing between the slits R. Into this passage-way is thrust a bar of wood or iron S,preferably oblong in cross-section. When this is done, the formerjaws Kare raised and the spring-arms M lift the webbing clear of the former-jaws J and allow it to be again fed through the machine, the second web P being pulled forward by the first web P. Bymaking the former-jaws with the open spaces between the fingers j and In it is evident that these jaws may separate without catching upon the bar or rod S.

I do not confine myself to the employment of my apparatus for any special manufacture, although I have found it especially Well adapted for uniting webbing in linoleum manufacture. Neither doI limit myself to any size of the machine, as the proportion of the parts would vary tosuit the industry to which it is adapted. While I prefer the general constructions herein set out, the details may be greatly varied without departing from the essential features of my invention.

Having now described my invention,what I claim as new, and desire to secure by Letters Patent, is-- 1. In a machine for temporarily connecting the two ends of two pieces of webbing, the

combination of cutting devices for forming through the overlapped webs a series of parallel slits, with two sets of former-jaws adapted to operate upon the webs from opposite sides one set of former-jaws acting upon the webbing between every alternate pair of slits and the other set acting upon the remaining portions between said slits, whereby the alternate portions are pushed in opposite directions to form a transverse passage-way through which a locking bar or rod may be passed.
