ence being had therein to the accompanying drawing.

constructions and arrangements which will *---be particularly pointed out hereinafter.

One of the objects of my present invention is to provide guides for the follower-' board to cause it to move in a fixed vertical line to prevent any binding of the cooperatin clenchin members the followerboard being preferably moved up by springs exerting uniform pressure thereon when released by the press.

Another object of my present invention is to have the clenching members carried by the follower-board to temporarily interlock the button washer so that when the clenching has been effected and the follower-board permitted to rise, the vertical movement thereof will carry with it the tufted pad so that it can be readily stripped or removed from the follower-board.

Another object of my present invention is to provide a new clenching button; and to combine therewith an improved button support, guide and piercing device which supports, guides and protects the open end of the button and pierces the cloth and lining, providing an initial opening therein through which the stem of the button may pass.

Another object of my present invention is to provide a universal movable clenching member, which is automatically centered by the combined button guide, support and protector to the end of the button to be clenched.

A further object of my invention is to provide an improved form of button clenching device, particularly intended for use with my improved form of button.

A further object of my invent-ion is to provide a button washer adapted to temporarily interlock with the clenching member, whether it be carried by the followerboard or is in the form of a hand-operated clenching device.

In carrying out my present invention, the usual or any desired type or form of moldboard 1, may be employed. The constructions of mold-boards are so well-known to those skilled in the art that a specific description thereof is unnecessary. Vertically movable within this mold-board is a follower-board 2-, which is provided at opposite sides with vertically projecting boards or members 3, to which are attached guiding 5 bars 4. The ends 5 of these guiding bars project beyond the side walls of the mold board 1, and are provided with vertical openings 6, which have their under or lower ends tapered at 7 (Fig. 12). These openings 6,' receive vertically arranged .guide rods 8 and expanding springs 9 are located around these guide rods 8 and between the ends 5 of the guide bars 4:, and the rod supports 10. These supports 10 are the form of sockets and are attached to the base 11 of the mold-board. These supports 10 removably receive the guide rods 8 which are held within the sockets by means of suitable thumb screws 12, which permit the rods to be attached and removed at will. The upper ends of the rods 8 are tapered as shown, which together with the taper 7 of the opening 6, permits the follower-board to be readily placed in position. The guide .rods and bars insure the accurate vertical movement of the follower-board within a fixed vertical plane when it is being clepressed and when it is permitted to be lifted by the springs 9, for a purpose which will be referred to farther on.

Located over the metal bars 1, are the wood bars or'strips 14;, which receive the pressure bar of any suitable form of bars for pressing the follower-board downward. These bars 14 are readily replaceable when they become badly worn.

Referring now to my improved button, and particularly to Figs. 7 9 and 11, it comprises a vertical hollow stem having a relatively large lower portion a and small upper portion 6. The upper portion bis made small or contracted in any suitable manner and is provided with several longitudinal scores or grooves 0 in its outer faces and notches (Z in its upper extremity, the

grooves o-r scores coinciding with the apexes of i the notches by means of the clenching devlce hereinafter described. Thls smaller or contracted end of the button is drawn through j these scores or grooves into separate memi bers or arms e (Fig. 9) which are turned downward 1nto clenching position against the washers 15, as shown in Fig. 4:, and. serve to firmly unite the button and washer 1 through the cloth and lining and to hold the parts of the pad in the tufted position. This button A is hollow and in operation is E supported, guided and protected by a combined support, guide, protector and piercer The hollow button in addition to forming an excellent clamping device for holding the cloth in a tufted position, performs a very useful additional function in respect to the 16, which passes through the hollow button.

v pad itself, in that it forms a hollow button for the pad through which the dust and dirt when cleaning the pad will pass and thus entirely pass through the pad. It is well-known that it is very diflicult to clean the depressed portions of tufted pads or seats with solid head buttons. With the hollow buttons this difliculty is overcome. Furthermore, when the tufted pads are used for out-door service, such as automobile and the like, the water from rains and dews which always accumulates in the depressed portions of the pads, will flow through the hollow buttons instead of being caught and held in the depressed portions as is now the case.

Attention is directed to the fact that the button support, guide and protector 16 is pointed at its upper end so that after the button is placed thereon, as shown in Fig. 3, the support projects beyond the button and the contracted portion of the button fits the support and the protector 16, whereas the enlarged portion a is larger than the guide and protecting rod 16, the function of which will be presently mentioned. The point ends of the guide and protector 16 are forced through the cloth 1'? by hand, when it is being placed in position in the moldboard, and thereby forms an initial opening through which the contracted notched end of the button passes. The button support, protector and guide 16 is removable from its socket 18 whereby it is removable so that rods of various lengths may be supported therein depending upon the character of work to be done, thus constituting a removable support and guide for the button. The socket-s 18 are attached to the bottom of the mold-board as shown.

The object of having the lower portion of the button enlarged is to prevent the button from being wedged or tightened upon its support and guide by the clenching operation. The clenching operation opens up practically all of the contracted portions of the button, leaving only the enlarged portion thereof in engagement with the support, guide and protector, and thus permits the tufted pad to be easily removed without any wedging or friction between the buttons and their supports.

Referring now to the button clenching devices, and particularly to the clenching device that is carried by the follower-board, reference is more particularly had to Figs. 5 and 10. This follower-board clenching device B, comprises a base fhaving a central opening 9. The clenching member it has a cut-away portion 71 and shoulder thereabove. Riveted against this shoulder is is a flange or washer Z, so that a space m is formed between the shoulder 70 and washer Z, and into this opening the inner periphery of the base f extends. The space on is of sufficient size to permit the clenching device to freely move in all directions upon the base f, and the base f is secured to the followerboard 2, the face of the follower-board hav ing a recess a to receive the inner end of the clenching device 71 This clenching device is provided with a central opening, the upper portion 79 being larger than the lower portion g. The under face of the clenching device 72. has a concaved portion 1, which has at its center a projecting conical flange or central projection s surrounding the smaller portion 9 of the said opening.

The washer 15, is of truncated coneshape, as shown in Fig. 6, and is provided with one or more arms 2., which are adapted to temporarily interlock with the clenching member 71, as shown in Figs. 3 and 10, the washer having a central opening a larger than but registering with the opening g of the clenching member.

In operation, the buttons A are placed on their support, guide and protector, as shown in Fig. 3. The cloth 17 is forced into the position shown by hand from the pockets. The filling 18 is placed thereon and the rods or supports 16 protect the buttons against the entrance therein of any of the filling. The washers 15 are placed upon the clenchers h and the lining 19 placed in position. The follower-board is then forced down into the position shown in Fig. 4, by any suitable press. The annular flange s of the clencher fits snugly the button support or rod 16, so that as it is forced downward, the rod passes through the opening p, g and the flange s engages the notched ends of the contracted portion of the button, forces them outward and the combined movement presses the contracted end of the button through the scores or grooves thereof forming supporting clenching arms which are carried down in contact with the washers 15, thus clenching the washers and buttons to the pad and holding it in its tufted position. As stated, the washers are interlocked with the clenching devices and are held thereto with sufiicient friction to lift the tufted pad from the mold-board as the follower-board moves upward, it being understood that the side portions C of the mold-board are first removed. When the follower-board 2 is released by the press after the sides C of the mold-board are removed, the follower-board is carried upwardly by the springs 9, and it carries with it a tufted pad. The follower board is then removed fro-1n the machine and the tufted pad readily stripped from the follower-board. As the follower-board is moved downward, the conical washers 15 will be engaged by the pointed ends of the button supports, guides and protectors 16, thus moving the clenching devices in line with the supporting guide if they should be out of line therewith. This arrangement avoids any necessity of absolutely and accurately positioning the clenching devices on the follower-board, because their free universal lateral movement, together with the conical washers, insures their proper positioning in respect to the buttons and thus insures the proper clenching of the buttons. WVhile this universal supporting arrangement for the clenchers is desirable in practice for the purpose stated, yet I do not limit myself to that universal movement, because the followerboard can be made to accurately move by suitable guides, and in this event the clenching devices could be made rigid with the follower-board, because by the accurate vertical movement of the follower-board and the accurate positioning of the clenchers on the follower-board so that they will always register with the button support, guide and protector, it will not be necessary to provide lateral movement of the clenching devices. As stated, however, this lateral movement in actual practice is considered the best form and desirable.

I'wish it to be further understood that my improved button washer and clencher is not dependent upon the attachment of the clenchers to the follower-board. The follower-board could be used without the attached clenchers and the filling forced down into position as in the usual form of follower-board, after which the hand clencher D, shown in Figs. 1A and 15, can be used. In this event the washer 15 is either placed over the button and then the hand device used to clench the button, or the washer may be temporarily attached thereto by the arms t, as shown in Fig. 15. The under side of the hand clenching device is shaped to correspond with the shape thereof in Figs. 5 and 10, when it is attached to the followerboard.

By having the clencher 7L (Fig. 10) with the central opening enlarged at the top, as shown at 79, further provision is made to decrease the friction between the clencher and the supports and guides 16, when the follower-board. is lifted. This enlarged portion of the opening, together with the enlarged lower end of the button relieves practically all of the friction between the button, the clencher and the support, guide and protector, after the parts are clenched in position, so that the friction between the arms 2. and the clenchers will be sufiicient to lift the tufted pad with the clenched buttons from the button supports, guides and protectors by the lifting of the followerboard 2, as previously explained.

I do not make any claim herein for the follower-board guides and springs, as this will be made the subject matter of a divisional application.

I make no claim herein for the improved hollow tufting button and washer, nor to either separately, as these form the subjectmatter of a divisional application filed May 12th 1911. I 7
