'7 Claims. 1

My invention relates to a machine for making pro-built borders for mattressts.

An important object of the invention is to provide a machine of the above mentioned character for use in connection with a standard sewing machine, which sewing machine may be readily applied in position and removed therefrom, as

desired.

A further object of the invention is to provide a machine of the above mentioned character wherein the sewing machine is'held stationary and the work is shifted longitudinally and laterally with respect'tov the sewing machine.

A further object. of the invention is to provide means for transversely reciprocating the work with respect to the sewing machine and effectin an intermittent longitudinal feed of the work at the end of each transverse stroke.

A further object of the invention is to provide a machine of the above mentioned character which is of simplified construction and is'relatively inexpensive to manufacture and automatlo and reliable in operation.

Other objects and advantages of the invention will be apparent during the'course of the following description.

on line 3-3 of Figure'2, the carriage being shifted to the left.

Figure 4 is a similar view with the carriage shifted to the right,

Figure 5 is a transverse section taken on line 5-5 of Figure 1, t

Figure 6 is .a vertical section taken on line 6-6 of Figure 5,

Figure '7 is a fragmentary plan view of the bore der produced bythe normal operation of the machine,

. Figure 8 is a similar view of the border produced by an adjustment of the machine, and,

Figure 9 is a similar view showing a border produced by a further adjustment of the machine. In the drawings, where for the purpose of.illustration is shown a preferred embodiment of my invention, the numeral 20 designates a carriage which is'shiftable laterally and held against longitudinal displacement. The :carriage comprises a lower horizontal framed I, supported bye riage.

" wheels 22, traveling upon stationary tracks '23.

The carriage further comprises a verticalframe 24, rigidly mounted upon the horizontal frame, nearer one longitudinal edge thereof. Extending into the upperportion of the vertical frame 24 and above thehorizontal frame 2!, is a horizontal table top 25 which is stationary and supported by legs .26 and diagonal braces 21. The table top 25 extends intothe central open space of the vertical frame 24 and will clear this frame during the transverse reciprocation of the car- Mounted upon the stationary top 25 isa sewing machine 28, of any well known or referred type. This sewing machine includes the usual arm 29 and head 30. The sewing machine is arranged upon the table top, so that the longitudinal axis of the arm 29 extends transversely of the carriage 20 or longitudinally of the direction of reciprocation of this carriage. The sewing machine includes the usual reciprocatory needle and the usual presser-foot used in-sewing quilting. The machine will sew the line of stitching in any direction, dependingupon the movement of thejwork with respect to the needle.

The conventional feed dog of the sewing machine may be removed as separate meansare provided to feed the work longitudinally of the carriage. Since the table 25 is stationary, 'thesewing machine is held stationary. This construction is advantageous inasmuch as it eliminates any special mounting for the sewing machine, as is done when the sewing machine is reciprocated. It

also permits of the sewing machine beingreadily separated from the table top so that such sewing machine may be used for. other purposes-if desired or a diiferent sewing machine susbtituted therefor. The sewing machine 28 may be driven continuously by a separate motor 3 I.

The carriage 20, embodies a shelf 32 upon which the folded ticking 33 may be supported and this ticking is passed about guide rollers 34 and 35, mounted upon the vertical frame 24. The'n-umeral 36 designates a roll of inexpensive fabric, such as tobacco cloth, cheesecloth, or the like. The fabric 36 is passed about a guide roller 31 also mounted upon the upper end of the vertical frame 24. The carriage further embodies a shelf 38 for supporting cotton wadding or batting 39, which is passed over the fabric 36, beneath the fabric 33 and over the guide roller 31. The

fabrics

33 and 36 pass from the roller 31 in superposed relation and the wadding or batting 36 is arranged between these fabrics, and the assembled fabrics and batting then pass beneath a transverse guide roller 40, arranged near and above the table top 25, to position the assembled work layers fiat upon the table top 25. The assembled layers of the Work will slide as a unit upon the table top, longitudinally or transversely of the table top. The work discharges from the table top 25 and passes between a pair of opposed feed rollers 4| and 42. The vertical frame, at the discharge side of the feed rollers, may be equipped with a table top 43, for supporting the finished work which will discharge downwardly from the table top and may be collected in a box or basket 44. The feed rollers 4| and 42 are em ployed to feed the work longitudinally, intermittently, and the lower roller 42 is driven for this purpose, as will be explained. 1

Mounted within the central open space of the vertical and horizontal frames of the carriage 20 is a stationary horizontal base or beam 45. Mounted upon the stationary base 45 is afixed bearing 46, holding ahorizontal rotatable shaft '41, held against longitudinal -displacement. A companion fixed bearing48 is mounted upon the stationary base 45 and holds arotatable shaft 49, also held against longitudinal displacement.

Rigidly mounted upon the" shaft. 4? is a. sprocket --whee1 59 and a sprocket wheel is rigidly mounted upon the shaft 49 and an endless sprocket chain 52is. passed about these sprocket "

wheels

50 and 5|.

The shaftsand .49 extend longitudinally of the frame 20,-whilethe sprocket chain 52 extends transversely-of the carr iage,.as

shown. The shaft 41 is driven by gearing 53,

which in turn may be driven from a motor 54.

" Any suitable'type of speed reducing gearing-may be employed.

. In order that-the carriage 20 maybe reciprocat'ed transversely by th'e'conti'nuous travel of the endless chain 52 in one direction, the carria'ge has a pair of spaced superposed

horizontal bars

55 and 56 rigidly secured thereto, and these bars extend transversely of the carriageand longitudinally of the endless sprocket chain 52,

above and below the same. The bars-55 and 56 "reciprocate with the carriage while the shafts 4-! and 49 remain in afixed location. The bar 55 has a depending peg or extension 51 rigidly secured thereto and the bar- 56' has an upstanding peg or extension-58 rigidly securedith'ereto.

' The pegs 51 and 58 are vertical andiare longitudinally staggered with respect to bars55 and 56,

Figure-5. Ihe pegs Hand 58 are arranged to. be

This shaft is arranged" nearithe endless sprocket v, chain 52 and-is parallel therewith. The shaft 6| has a'sprocket wheel 62 rigidly secured thereto,

engaged by a sprocket chain 63,1enga'ging.a sprocket wheel 64', mounted upon a transverse shaft 65, supporting and'driving thelowerfeed roll 42. It might be'stated-that the shaft.26| "is intermittently turned and this operatesthe feed rollers 4|and 42 to intermittently feed the work.

Rigidly mounted upon the shaft6| is a disc v66, having four pins 6! rigidly secured thereto and extending axially thereof. These fourpins are arranged 90- degrees apart; whereby the pins are disposed in diametrically .opposite pairs. -s"traight lea-r68 is rigidly mounted iuponithe shaft 6| 'a'ridh'asa; pair;of diametrically oppositely arran ge'd' pins- 69 rigidlymounted thereon and .ex-

. engages the lower peg 59.

66 and 68 are spaced longitudinally of the shaft 6| for a distance corresponding generally to the length of the endless chain 52. The sprocket chain 52 has horizontal transverse pins '19 and H rigidly secured thereto and projecting laterally beyond same for co-action with the pins 5? and 69, as will be explained.

The operation of the machine is as follows:

7 It will be assumed that the work has been passed beneath the presser foot of the sewing machine and is engaged between the feed rollers The sewing machine is constantly operating and the shaft 41 is continuously driven clockwise,,Figures 1, 2, 3 and 4, and counterclockwise, Figure 5. The pin 59 which is now at the lower rung of. the endless chain 52, is brought into engagement with the lower peg 58, and the carriage is shifted to the extreme left, Figure 3.

'When this position is reached, the pin 59 travels about the sprocket Wheel 5|, Figure 5, and dis- The carriage is now at rest and will remain. atrest until. the pin-59 engages behind the upper peg-51. -Whilethe carriage is thus at rest in the extreme left position, the pin I0 is traveling. downwardly about the sprocket wheel and will engage the. pin 61, turning the disc 66, turning the shaft.6|,. which in turn turns the lower feed roller 42 to feed the work a step. By the time the pin 59 engages the upper peg 5l,-the pin 18 has moved thepin 6'! to the lowermost position and the horizontal travel of therun of the sprocket chain-52 will move the pin 10 horizontally out of engagement :with the pin 67. The carriage is nowibeing .lshifted to the rightand the extreme right position is shown in Figure 4. When the extreme right position, Figured, is reached, the pin 59 is passing downwardly over the sprocket wheelz50, at which time the pin 59 will disengage the upper peg 51, and the. carriage will be at rest, while the pin is traveling about the sprocket wheel:50. The pin fl is now in proximity to the bar68, which has been shifted to the right andwhen the pin travels downwardly about the sprocket wheel 50, the pin engages the pin 69 of'the bar 68, during the rest periodof the carriage,

turning the .bar.68 and shaft SI and. effecting the next intermittent movement of the feed roller When the pin59 againreaches the'lowered position, it will engage behind the peg '58. and

the carriage is again shifted to the left and the operation is repeated. vIt is thus seen'that the carriage is shiftedtransversely in. one direc- -tion and stopped, andthen the work is fed longitudinally .a step and thecarriage thenshifted transversely in the opposite direction and stopped and the .work fed a step, and this cycle ofjoperation is repeated. This results in the intermittent longitudinal feedof the. fabric andbetween the intermittent longitudinalfeed, :the fabric 'is'lshifted transversely with respect to the sewshown in Figure 8 is provided, including" U- shaped portions having transverse portions-i5 which aresewed into or over each, other.

I .1 alsorcontemplate operating the machine so -that the work may be provided.with longitudinal lines of stitches 16 instead of transverse stitches.

- :ro so this, the rotation of the shaft: is stopped and the shaft 61 is continuously driven, which a may be effected by a'gear ll mounted thereon The sewing machine then will produce the long tudinal continuous lines of stitching since the;

machine is used in this W y, I contemplate em;

ploying a sewing machine having a plurality bf needles sothat a plurality of lines of stitchesis produced at one time. The sewingmachine used to produce the trans verse and longitudinal lines of stitching has the ordinary feed dog mechanism removed, as feeding iseffected bythe shifting of thewor-k bodily bymeans of thecarriage and the in mittent rotatin of the feed rolls while the=swing machine remains stationary. Any suitable type of sewing machine may be employed which will sew and permit of the work being shifted in different directions.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same and that various changes in the shape, size and afrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
