SPECIFICATION forming part of Iletters Patent No. 524,995, dated August 28,1894 Application filed November 14, 1893. Serial No. 490,874. (No model.)

To a/Z Z whom it may concern:

3e it known that I, EDWARD B. ALLEN, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Guides for Carpet-Sewing Machines, of which the following isa specifi-' track or guideway parallel with which the carpets are suspended vertically.

My improved guide is made in the form of a saddle or inverted trough having depending outwardly flaring sides or flanges which converge toward the re'ar. or needle end of the guide, near which end they are slotted for the passage of the needle and the threads which form the double loop stitch seam,'the troughshaped or saddle guide having, centrally placed between its depending sides, a dividing plate or divider, to hold the pile fabrics .separated from each other, while below and sustained by said divider is preferably pro vided a separator which holds the suspended fabrics a little distance apart below the divider so as to have a tendency to curve the fabrics to bring their edges together in, such a position as will assist in turning in the pile and partially abut the edges. For securing the best results the forward end of the divider 1s rearward of the forward end of the saddleshaped guide and the rearward end of. said divider is just in front of the needle slots in the side flanges of the guide, while the rear end of the separator is some little distancein front of the needle slots, and the forward end of said separator is preferably in front of the forward end of the divider. Also a part or all of the guiding surface at the apex of the saddle guide is preferably inclined downward rearwardly so that'as the guide travels forward over the carpet edges (which are held a little higher than the guiding surfaces at the apex of the saddle guide) said edges will be depressed to force in the pile; and owing to the fact that the rear end of the separator is some little distance in front of the needle the positions of the fabrics held apart by the said separator will be permitted to come together just before being reached by the needle; while the pile, pressed inward by contact with the divider, will be retained in itsinwardly forced position until the edges have been joined by the stitch-forming mechanismof the traveling machine.

In the accompanying drawings Figure 1 is a side view of my improved guide, and Figs. 2'and 3 aretop and front end views, respectively, of the same. Fig. 4 is aside view with one of the side flanges cut away to show the line of the guiding surface at the apex of the trough-like or saddle guide. Figs. 5 and 6 are sections on lines 5-5 and 6-6, respectively,

of Fig. 1, the positions of the fabrics to be joined being denoted by dotted lines in Fig. .6, and Fig. 7 illustrates a slight modification.

A denotes the inverted trough-shaped or saddle guide consisting of depending outwardly flaring side flanges meeting on-a curve at their upper edges, said flanges converging somewhat toward each other from their front ends I) to their rear ends 0 and being provided withneedle and thread slots or openings ta The guiding surface of the fabric edges is at the apex of the trough and this guiding surface is preferably made, as shown in Fig. 4, with a straight or horizontal portion (1 and a portion 6 which inclines downward rearwardly,

while just at the rear end of the downwardly inclined part c of the guiding surface is formed a slight downward jog or projection f. It is not, however, essential that a part of the guiding surface at the apex of the troughlike or saddle guide should be horizontal, as such guiding surface, forward of the needle slots, might incline downward gently all the 7 way from the front end of the guide, as shown in Fig. 7.

Centrally secured to the under side of the saddle guide'is a depending dividing plate, or divider, g, the rear end of which terminates just in front of the needle and thread slots h formed in the side flanges of the guide, while below and supported by said divider is a separator '5 which is thicker than said divider and. which is preferably pearshaped in cross-section, as shown by' Figs. 3 and 6. The forward end of the divider g is some little distance rearward of the forward end of the saddle guide and also preferably j rward of'the'forward end of the separator 'L. The side flanges of the guide A are preferably provided internally with slight projections a adjacent to the slots h, said proections assisting in bringing the fabric sections together at the sewing point.

To the saddle guide A is soldered or other-v wise secured a block a by which said guide is to be removably attached to the traveling sewing machine, the positions of the vertically suspended fabrics over which the guide is to travel being denoted by dotted lines in Fig. 4. As the upper edges of the fabrics, or the edges to be joined, are held a little higher than the guide, the latter, in riding over said edges forces them downward; while the separator, holding them apart, serves to assist in curving the fabrics outward from each other, I as shown in Fig. 6, thus turning in the pile and bringing the extreme edges of the carpet sections together partlyabutted, the operation of turning in the pile being assisted by g the projection f at the rearend of the inclined part e of the guiding surface of the guide.

It-will be observed, from the locationof the needle openings a formed in the depending sides of the guide between the ends thereof, u hat said gu d s adap e t h ld a d 1 2 th a s t in fr hthh r arwar Of I the needle. Y

Having thus described my invention, 1 claim and desire to secure by Letters Patent 1.
