SPECIFICATION forming part of Letters Patent No. 443,673, dated December 30, 1890.

Application filed July 26, 1890, Serial No. 359,991, (N0 inodel.)

To aZZ whom, it may concern.-

Be it known that we, ABEL II. FROST and FRED L. BRYANT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mat tress-Making Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in wire-coiling machines adapted to automatically weave coiled-wire fabric for bed-bottoms. lleretofore machines for this purpose have embraced a table upon which the fabric lies while being made and a coiling-machine arranged at one end of said table and run by hand or other power. Before the end of the wire strand is thrust forward into a marginal coil of the fabric being woven the said fabric has been moved longitudinally toward or from the coiler about half the width of a coil in order to insure the entrance in the said marginal coil of the end of the strand of which a new coil of the fabric is about to be made. l Vhen each coilhas been completed,tl1e fabric has been moved bodily across the machine a distance equal to about half thelength of one twist of the coil for the same purpose.

These two movements have in some cases heretofore been accomplished by moving the coil by hand and in some cases by having automatic mechanism for bringing the final coil or the fabric into linear position for the insertion of the next coil and for moving the final coil longitudinally after the completion of the same.

In the present invention we desire to retain the coiled fabric upon the table as it is being made and to move the coiling mechanism longitudinally to and from the fabric before a coil is to be formed and to also move said coiling mechanism after a coil is formed transverselya distance equal to about one-half the diameter of the coil. In other words, the fabric is held on the machine while the coiling device or fabric-making mechanism is moved transversely and longitudinally, as required.

To this end as well as to the production of a cheap and durable machine the invention a machine embodying our invention. Fig. 2 is a side elevation of the same. Fig. 3 1s an end or rear elevation of the machine. Fig. 4

is a transverse sectional view of a portion of the machine, taken upon line 4 4 of Fig. 2, looking in the direction indicated by the arrows and omitting the upper portion of the machine, embracing the coiling mechanism. Fig. 5 is a sectional view on line 5 5 of Fig. Fig. 6 is a section on line 6 6 of Fig. 5. Fig. 7 is a plan view of one of the movable tables on which the coiling devices are supported.

The coiling mechanism,consisting of the feed-rolls and the coiling-spindle and means for operating the same herein shown, are substantially the same as shown in our former patent, No. 296,551, granted April 8, 1884, and are simply here used for the purpose of illustrating the invention, as any other coiling devices may be used. lVe do not, therefore, minutely describe these parts, but here refer to the said patent for a more complete eXplanation of the construction and operation of said coiling mechanism.

It will subserve the purposes of this invention to state that the wire is fed into the coiling apparatus A at a and is forced out of the same over the coiler proper at a the several parts of the coiling apparatus being mounted upon a table or platen A.

B is the frame of the machine proper, composed of the standards 6, upper and lower longitudinal side beams b 12 and upper and lower end or transverse beams b 5 Supported upon the side beams 17 by the standards b is a table B. It is upon this table that the fabric is made and allowed to remain immovably in position as each new coil is added thereto or until the entire fabric is completed. The table B does not extend entirely to the end of the machine, as more clearly shown in Figs. 1 and 2. At the rear end of the machine and resting upon the beams 12 we place the transverse tracks B. These tracks support the two carriages here'- inafter to be mentioned and the table A.

The first or lower carriage consists of two transverse beams C, united at their ends by rods or bolts c, the beams C resting upon and adapted to be moved freely upon the tracks B The beams C, as will be noted, extend across or transverse of thetracks and carry upon their upper faces runners or tracks C. It is upon these runners or tracks C that the upper table C is loosely fitted and adapted to move. The table A rests upon and is secured to the upper table C 1) is a shaft supported in suitable bearings d from the frame of the machine, at the end thereof, (see Figs. 1 and 3,) carrying upon its end a flanged pulley-wheel (1. Power may be transmitted to this shaft from a suitable source of supply by means of a belt passing over the pulley d. The shaft D is provided longitudinally with a groove (Z Mounted loosely upon the shaft D is aspindle or sleeve D, provided with a suitable feather adapted to enter and slide in the groove (Z of the shaft D, so that said spindle or sleeve will rotate with the shaft D, while at the same time it may be moved longitudinally thereon between the bearings d. Secured upon one end of the sleeve D is a flanged pulley-wheel d over which a belt (1 is trained, so as to connect a similar pulley-wheel (1 mounted upon the coiling-table, and by which the necessary power to operate the coiling mechanism A is obtained from the shaft D. By reason of the feathered connection of the shaft- D and the sleeve D we are enabled to have the coiling mechanism in operation constantly while carrying the latter to and fro across the table. It will also be noted that by reason of the belt connection (1 the coiling mechanism may be moved to and from the shaft D a short distance without interfering with the transmission of power to the latter.

' E is a shaft mounted in suitable hearings in the frame of the machine, and to which power may be supplied by any suitable means. The end of the shaft projects beyond the transverse bar I)" and is there provided with a wheel E. The outer face of this wheel is provided with two sets of cogs or teeth 6 e, the intermediate portions 6 of the face being smooth and free from obstruction. Secured in bearings 6 upon the end standards Z) of the frame is a worm or screw-threaded shaft E Near one end of this shaft E is a beveled wheel or pinion E the teeth of which are adapted to engage the teeth 6 c 011 the wheel E. F is an arm or bracket, the upper end of which is rigidly secured to the lower carriage by means of bolts f passing through its end and engaging one of the transverse beams C. The lower end of this arm F is provided with an enlargement or block f. Within this block f is a cam-plate F, having a pin or stud thereon which proj ectsthrough the face of the block f, to which the handle f is secured, so that the said plate F may be rotated within the block f. On either side of the shaft E is a nut f Each nut is provided with a pin or projection which enters a suitable slot in the disk or plate F, so that the rotation of said plate F will move the two nuts toward or away from the shaft E -that is, into and out of engagement with said screw-threaded shaft. This is a familiar mechanical construetion. Any other well-known means for securing the arm F so that it will travel lengthwise of the shaft E as the latter is rotated may be employechif desired.

It will be obvious from the above construet-ion that when power is applied to the shaft E, so as to rotate the same, and the bar or arm F is engaged with the shaft E by a movement of the handle f every rotation of the wheel E will cause the shaft E to be rotated intermittently-that is to say, the pinion E will first engage, say, the teeth 6 of the wheel E and will be rotated until the space 6 comes opposite the pinion E whereupon the shaft E will remain stationary, while the wheel E continues to rotate. Shortly thereafter the teeth 6 engage the wheel E and again the shaft E is rotated. When the shaft E is rotated, it works in the engaging-nuts f and consequently will move the arm F and the parts engaged therewith so long as the shaft E is rotated, and as soon as the said shaft ceases to rotate the arm F and the parts secured thereto remain stationary. In this manner the lower carriage and the ceiling mechanism are moved across the table intermittently. The length of this travel or movement obviously depends upon the number of teeth (2 e. As here shown, the number of teeth is sufficient to cause the carriage and coiling mechanism to move forward a dlstance equal to about one-half the diameterof acoil. Should itbe desired to run two strands of wire in the same coil, one of the sets of teeth 6 or e may be omitted.

To give the coiler a movement upon the lower carriage to and from the fabric the following mechanism is employed: A shaft G is mounted transverse of the machine in suitable bearings g, located upon the lower side bars 0 At either end of this bar G are rigidly secured the links G, the upper ends of which are enlarged to afford bearings for a spindle or connecting-bar G which latter is rigidly secured in said upper ends of the links G. Secured beneath the center of the table C by the bolts g is a yoke or bracket G which passes over and is loosely engaged with the upper bar G Any rotation or oscillation of the lower shaft G is transmitted to the upper bar G by the rigidly-connected links G. The bracket G is consequently given an oscillatory movement forward and back, the length of throw depending, of course, upon the oscillation given to the shaft G.

The shaft G is operated by the following mechanism: Upon the shaft E at a point inside of the cross-bar b of the frame the disk II is mounted, said disk having upon a portion of its face it a circumferential flange constituting a cam 72. Upon the shaft G is rig- ITS idly secured an arm H, the upper end of which is adapted to engage the face 7t and the cam h of the wheel H. To lessen the friction at this point we find it convenient to provide the upper end of the bar or arm H with a friction-roller 72?, loosely mounted over a stud 7L3 secured in the end of the arm H. A spring H is interposed between the arm H and the transverse bar I). Said spring tends to draw the upper end of the bar H at all times against the cam wheel or disk H. It will be manifest that the rotation of the wheel H will cause the upper end of the arm H to oscillate forward and back, as the friction-wheel h first engages the face 72, and then rides upon the cam h, and then drops back again to the face h of the wheel H, and also that this forward-andbackward or oscillatory motion of the upper end of the arm H will be communicated to the upper table 0 through the medium of the shaft G, the links G, the bar G and the bracket G For the purpose of properly effectin g this oscillatory movement of the table 0", which in practice is about one-half an inch in length, the said table 0 is mounted somewhat loosely upon the tracks 0'.

The coiling apparatus and the carriages upon which it is mounted travel across the machine in the direction indicated by the arrow in Fig. 1, starting nearest the pulleywheel (1. YVhen it is desired to return the tables and coiling apparatus to that side of the machine, the handle f is operated and the nuts f thereby loosened,whereupon both tables may be moved bodily across the machine, the nuts f not then being engaged with the worm-shaft E lVe do not desire to be limited to the specitic devices herein illustrated and described for rocking intermittently the lower table C nor to the mechanism for giving the longitudinal movement to the coiling devices, inasmuch as other well-known mechanisms will readily suggest themselves to skilled mechanicians, and because the essential feature of our invention does not consist in the details of the devices herein shown.
