TodZZ whom it may 00mm:

Be itknown that 1, RALPH a citizen of the United States, residing in Chester, Delaware County, Pe nnsylvania,

have invented certain Improvements in Machines forspllclng Felts and'Fabrics, of.

. which the following is a specification.

'My invention is especially adapted for splicing felt which has to be coated by being passed through a coating or saturating .machine. In this'type of machine, a roll of felt is passed therethrough until the end I is reached, which end is secured to apiece of another roll, rendering-itunnecessary to thread the new roll through the machine, as it is drawn through by the rollv to which itis attached. The ends are preferably detached afterthey have passed through the v 1 machine so that each" roll canbe handled independently. I

The object; of

,vide a machine by which pieces of felt can .be secured together, in a rapid manner. I 7 a --:-I-n the accompany drawings substantial and Fig. 1 is a plan view ofmy improved machine: for splicing feltand other fabrics;

:Fig. 6 is a view showing the two pieces of fabric punctured by the needles with the threads projecting through the perforations and also showing the draw:wires threading the several loops; 1

Fig. 7 is a sectional view'on the. line 7,

Fig. 8 'is a detached perspective view of Referring to the drawings, 1 is a frame.

supported on suitable legs 2. Carried by this frame aretwo beams 3 spaced apartto form a channel i extending from one end of the machine to the other. Mounted in the channel tie the needle carrier 5, shown G. J AonsoN,

through .the

V y; invention is to pro clearly in Fig. 5,]and-pjrojecting from this carrier arethe two lines of needles 6, preferably of thetype shown in Fig. 5, said needles being shaped to penetrate the felt and having a notch 8. to receive the transverse threadwhich is passed through the loops when the needles, with their loops, are

projected through the fabric, as in 7.

At the end of each needleis a groove 7 for the other thread, or cord, whichis placed in the grooves, as shown clearly in Fig. 4.

a: isone sheet of felt and b is the other sheet of felt, which is secured to the sheet a.

0, 0, are the cords, which are formed into loops. d, d are the cords which pass loops and which complete the stitches. I

The needle carrier is raised. and lowered 1 by means of plungers, Fig. 2. each of which is connected to one arm of a bell crank lever 10, pivoted at 11 to the frame 1. The other arm of each bell crank lever is connected by .a rod 12 to a lever 13 pivoted at 14 to a bracket on one of the legs 2. This lever 13 has a handle 15 by whichthe operator moves'the lever.

. When it is wished to release the needle carrier and lowerit. the dog is raised clear of the plate :16, when the weight of the needle carrier will cause it to drop to its normal. posltlon. I The needle carrier has I On theframe is a plate and pivoted to the lever '13is a toothed projections'lS at each end resting against abutments 19 on the frame. Directly above the needle carrier is a bar 20. This bar has a series-of perforations corresponding with the needles so that theneedles, when the needle carrier is raised, pass through thefabric and into the perforations of the bar. In the drawings, this bar is shown as made in two parts, or sections. This bar is carried by the upper clamp members 21 located at each side of the machine. EX- tending fromone clamp member tothe other are metal bars 22. '7 Clips 23 on the bar 20 engage the cross bars 22 and hold the bar 20 in'position so that it will movevertically with the clamping members 21.

The bar 20 is "held against longitudinal movement by guides 24 mounted on brackee s 2:5 secured'to the frame 1. The beams 23 are permanently secured to the frame 1 and form thelower clamping members.

In order to raise and lower the upper clamp' nembers 4, two shezts 726 are provided adapted to hearings on the beams 3. (in these eliaits are eccentrics 27 mounted in straps 28 connected by rods 29 to pins on the upper clamping members. 'Handlcs 31 a are provided tor turning the shatts 2 6 and their eccentricso that bythis means the .tvro pieces oi l Ql't are firmly clamped to a ther While the needles are proj cted o tarough the felt.

The cord 0 is pla ed in the groove 7 of the needles, as shown in Figs 4 and 5, each needle being; threaded in the same direction and i sucha manner that when the needles are zrorced through the felt, a loop oi the cord 0 is carried through the felt with each needle. After the needles are threaded, the.

parts of the machine are in the position sho vnin Fig. 3, the clamping 1 embers bein;- raised.

"The felt, which is passed through the saturating niachinc, is stopped When the end of illl piece of felt Z), the two felts having been the twosections of teltare directly above the felt is in position above the splicing de vice. The end of the felt a, as shorvn in Fig, 5, 1s lapped over the end of another cord cut each end, making line of stitches throu wet the Width of the fabric and the needles are Withdrawn. These stitches firmly splice the two ends of the felt together so that when the coating machine is set in motion one felt draws the elt o f the other i in through the space between the rolls Q or saturating machine lin tiie present instance, after the splice has passed through the machine, the felt is cut at this point and the roll previously coatin line with the toe loops of the" first cord so P after being drawn through, are tied to the cd is removed. from the machine and the new felt forms another roll.

I claim:

l. The combination in a machine or splicing feltand other fabrics, of two clamps spaced apart for holding two overlapping pieces of felt; a needle carrier having a series of needles, each needle having a slot in its end for the reception of a cord and also having a notch atthe side for the reception of a tying cord; means for causing; the neodles to puncture theftelt hold'l'ietiveen'the clamps, the said needles carrying with them loops ot'one cord; and means for passing another cord through the notchesin the nee-.1

dles, and theloops so that, when theneedles are Withdrawn and the slack of the cord is taken up, thetwo piecesoffelt are firmly secured together.

2. The combination in a machine for splic ing'two pieces of felt,for other fabric, of

two clamps spaced apart; a needle carrier located between the clamps; two series of needles carried by the clampsya bar above theneedle carrier and having perforations the needle bar and forcing the needles through the felt, said needles being arranged to carry a loop of a cord through the pertorati in :lelt'to forma loop and means lor passing a second cord get, when the needles are Withdrawn and e'cl'emps' are released, the two pieces" of material are firmly secured together.

needles; means for raising 3. The combination in a'machine -lor' splic- 'ng felt and other fabrics,o;t two-clamps p ced apart, eaclrclamp consisting oli'a 1X d member and a clamping member; an eccentric for operating the cla1nping inemher to clamp the two pieces ofoverlappln material, a perforated bar attacheuto the clamping; members and movable therewith; a needle-carrier located bet v'een the clampmembers and having a row of needles i arrangedto "pr held means for raisins;- 1', the needles i'e ends to receire a cord through L1G- mater-ial with the needles to form and L r m notch at the side for the i a draw Wire and the cord to which i t is attached.
