SEAMRUBBING OR PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,407, dated May 4-, 1886.

Application filed February 1'7, 1886. Serial No. 192,173. (No model.)

I 0 aZZ whom it may concern.-

Be it known that I, CHARLES W. COLLYER, of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Seam Rubbing or Pressing Machines, of which the following description, in connectionwith the accompanying drawings, is a specification--like letters on the drawings represent- Ing like parts.

This invention is an improvement upon United States Patent No. 324,085, granted to me August 11, 1885, to which reference may be had, the object of the invention being to simplify the construction of the machine therein described as to details, thereby rendering the same capable of doing better work.

In accordance with this invention the reciprocating cross-head carrying the tool which bears upon the material slides infixed bearings, while the work-support is yielding to compensate for leather of various thicknesses. The tool-carrying cross-head is reciprocated by a crank and crank-pin carried by the main rotating shaft, and the pawl-carrier mounted upon the shaft carrying the rotating wheel which bears directly upon the seam to be pressed is moved by an eccentric-rod connected with an eccentric upon the main rotating shaft, the pawl carried by the said pawl-carrier rotating the ratchet fixed to the shaft carrying the seam-pressing wheel or roller step by step, such movement imparting to the seam-pressing wheel or roller an intermittent rotary movement,as in the patent referred to.

The mechanism employed to direct the seam beneath the roller consists of a spi'ingcontrolled arm mounted loosely upon the shaft carrying the seam-pressing wheel or roller, the forward end of the said arm being provided with a short arm extended at right angles thereto and transversely across the work-support, 011 which is mounted adjacent to each other two spring-controlled clamps or presserfeet, the latter being cut away or beveled outward at their forward ends to permit the seam to enter between them, the presser-feet spread ing according to the width of the seam.

The work-support consists of a pivoted spring-controlled supportinglever carrying a stationary work-support, and cooperating therewith is a curved horn, the free tapered wheel, 0, having a end of which passes upward beneath the clamps or prcsser-feet and terminates between the work-support and the seampressin g wheel or roller, the material being fed over the said curved horn, and the presscr-feet bearing against each side of the seam.

Suitable means are supplied for depressing the pivoted supporting-lever when it is desired to remove the material from between the Work support and seam pressing wheel or roller.

Other features of invention will be hereinafter more fullydescribed.

Figure '1 shows !in front elevation a seam rubbing or finishing machine constructed in accordance with this invention; Fig. 2, a vertical section of Fig. 1, taken on the dotted line we, looking towardthc right; Fig. 3, a partial vertical section of Fig. 1, taken 011 the dotted liney y;looking toward the left, and Fig. 4 details of the clamps or presser-feet.

The frame-work, consisting of the arched portions A A, rising from tliebase-plate A, the central portion of the said arched frame being cut out to provide a space for the reciprocating cross-head C, is similar to the framework of the machine in the patent referred to. The main rotating shaft a, having its bearings in the arched frame A, carries adisk, 15, having a crank-pin, 16, which latter is provided with a slide-block, b, which it moves vertically in the guide-frame b, forming a portion of the cross-head O, rotation of thesaidshaftathera by reciprocating the cross-head. A frame, I)", depending from the reciprocating guideframe L, carries the tool, which bears upon the edges of the leather formed by the seam to press the same. The tool herein shown is substantially the same as described in the said patent, it consisting, essentially, of a pressing wheel or roller, 0, mounted upon a rotating shaft, which latter has its bearings in the lower end of the frame 1), adj ustably secured by sctscrew 2to the frame I)". The shaft carrying the seampressing wheel or roller calso carriesaratchetspring-controlled pawl, c, to prevent backward rotation. A pawl carrier, 0 is also mountedloosely upon the said shaft. Its pawl c engages the teeth of the ratchetwheel 0, and the said pawl-carrier is partially rotated by the eccentric a upon the main rotating shaft, the eccentric-rod a of which is connected with the pawl-carrier by the screw 3. To the opposite end of the shaft carrying the seam -pressing wheel or roller 0 a short arm, d, is loosely connected, the flange d of which is cut away, as at d, in which the pin or stud 4 follows, to thereby limit the rising and falling movement of the said arm on the shaft, the spring (I normally retaining the said arm in depressed condition. To the extreme end of the said arm dashort arm, d,is attached, extending therefrom at right angles and directly across in front of the seam pressing wheel or roller 0 adjacent to the work-support. Two clamps or presser-feet, e 6, (see Figs. 1 and 4,) are mounted upon the arm (1*, the contiguous sides of the said presscr-feet being cut away, as at 21, in which the stud 20, fixed to the arm (2, follows, thereby limiting the rotation of the presser feet upon the shaft and preventing their direct contact. Two springs, e a, surrounding the said arm (2*, bear against the outer sides of the presser-feet, theopposite ends of thesaid springs bearing one against the arm d and the other against the flange 6*, th ereby normally serving to keep the said presserfeet in proximity to each other. The forward ends of the said clamps or presser-feet e e are cut away or flared outward to permitthe seam of the leather to pass between them, to thereby present the seam properly beneath the wheel 0, the said feet yielding laterally to the width of the seam to be pressed and vertically to the thickness of the material.

The work-supporting mechanism consists of the supporting-lever B, pivoted at 7 to the frame B, mounted upon the base-plate A of the machine, the said lever B carrying the work-support f, which is provided with a suitable grooved surface in which the material may enter, as in the patent referred to. The curved tapering horn f, secured to the lever B by the screw 8, extends upward and passes beneath the yielding presser-feet and between the work-support f and the seampressing wheel 0. The lever B is held in elevated position in a yielding manner by a stiff spring, Bflsecured to the frame B, said spring, by means of an adjusting-screw, B", bearing with more or less force against the under side of the forward end of the said lever B, or beneath the work-support. The leverB is slotted at 25, in which a pin, 26,follows, to thereby limitthe movement of the said lever on its pivot and prevent the work -support from coming in direct contact with the seam-pressing wheel or roller 0. A hand-lever, D, strides the shank of the adjusting -screw B", and bears against the under side of the overhanging portion B of the frame B, the said lever D being notched at its forward end, as

at 9, to permit the projection 10 of the said overhanging frame B to enter, while the extreme rounded end of the said lever D enters a rececs, 12, of the said frame, serving as apivot upon which the hand-lever is turned when depressed by the operator bearing upon the extended portion D. By this hand-lever it will be seen that the pivoted supporting-lever may be depressed at any ti me, to permit any material between the wheel or roller 0 and the work-support to be withdrawn.

The work-support f consists in thisinstance of a four-sided plate fixed to a shaft, 13, rigidly connected with the work-supporting lever. Athumb-screw, 14, passes through the said supporting-lever near the bearing for the shaft 13, which enters one or another hole, 17, bored in the side of, the said plate f, so that when one or another side of the said plate or work-support is desired to be usedthat depending upon the quality and thickness of the material-one or another of the holes 17 is brought to register with the thumbscrew, which upon being turned locks the plate or work-support in fixed position, in order that a stationary work-support may be formed over which the material travels.

The plate or work-support f is herein shown as having four different surfaces, consequently four holes; but it is obvious that any other number may be employed if desired; also, that the means herein shown for locking the same in any position may be modified without departing from this invention.
