v 25 Claims.

Thi invention relates to garment trimming machines, and more particularly to a dress or skirt trimming machine which is more particularly designed and intended for use by large scale production dressmaking establishments for accurately trimming or cutting dresses or other garments at high speed to the required predetermined length.

It is one of the objects of the present invention to provide a single-motor driven rotatable dress supporting form and cutting or trimming mechanism together with noveland effective means for smoothly and positively feeding the dress material to the rotating cutting member.

It is also anotherobject of the invention to provide an improved mounting and arrangement of the operating motor with the cutting and feeding mechanism whereby they may be easily and quickly moved as a unit into and out of operative relation with the rotatable dress supporting form.

A further object of the invention is to provide an improved mounting of the feeding mechanism and means for operating the same from the motor driven cutter shaft.

An additional object of the invention is to provide an improved mounting of the rotatable dress supporting form and a drum connected therewith for unitary rotation and operative engagement by the feeding means, together with mean for vertically adjusting said form relative to the axis of rotation.

It is a further general object of the invention to provide a garment trimming machine as abov characterized which is comparatively simple in the construction and arrangement of its several parts, not liable to get out of order, and which may be operated at very high speeds with an appreciable increase in the quantity production of such trimmed garments over machines of this kind as heretofore used in the art.

With the above and other objects in View, the invention consists in the improved garment trimming machine and in the form, construction and relative arrangement of its several elements, as wil1 hereinafter be more fully described, illustrated in the accompanying drawing and subse quently incorporated in the subjoined claims.

In the drawings wherein we have shown one simple and practical embodiment of the invention and in which similar reference characters designate corresponding parts throughout the several views:

Fig. 1 is a front side elevation, partly in sec-- tion, of one embodiment of our improved garment trimming machine.

Fig. 2 is a top plan view thereof, the garment supporting form being omitted.

Fig. 3 is a horizontal sectional view taken substantially on the line 33 of Fig. 1.

Fig. 4 is a vertical sectional view line 4--4 of Fig. 2, and

Fig. 5 is a rear side elevation of the machine.

In the illustrated embodiment of our invention, we have shown the movable parts of the mechanism mounted or supported upon acommon base structure 5. Preferably, structure is in the form of a hollow elongated casting of light metal, such as aluminum alloy, and it is of the required form and dimensions to provide the requisite stability forthe movable machine parts.

At one of its ends the base'casting- 5 is centrally formed on its top wall with an upstanding bored boss 6 to receive the lower nd of a vertical shaft or spindle l which is supported at the upper and lower ends of said boss by the anti-friction bearings indicated at 8. A member 9 loosely surrounds the spindle I for vertical movement relative thereto. and supports a bearing plate Ii! having a sleeve I I extending downwardly through an opening in the member 9 and receiving the nut l2 threaded on the lower end of said sleeve. A base member I3 is rotatably supported on the member 9 by the anti-friction bearing means l4 and is rigidly connected with respect to'forces in a horizontal plane by means of a plurality of vertical rods 15 with the member it fixed to the bottom face of the dress supporting form Ii.

The rods l5 are vertically movable through spaced openings formed in the hub portion Zii of the internal spider I9 of a metal drum E8, the said spider hub 20 being rigidly fixed in any suitable manner to the spindle "l. Preferably, the cylindrical wall of the drum i8 ha an inwardly inclined upper end portion it! for the purpose of directing the material of the garment supported on the form I! to the feeding and cutting mechanism to be later described.

The member l6 has free sliding movement along the spindle I and the upper end portion of said spindle extends loosely into an axial bore 2| in theform H.

At the opposite end of the base 5, a'tubular column or standard 64 is suitably mounted at its lower end. Within this standard a threaded adjusting rod 65 is suitably mounted, and upon the same the traveling nut 66 has threaded engagement. One end of a horizonta1 rod 61 is taken on the this base wheels and the driving belt.

the vertically positioned shaft 42 in fixed ing relation therewith.

suitably fixed to this nut and extends outwardly therefrom through a vertical slot in the wall of standard 64, the other end of said rod being fixed to the member 9. Above the standard 54 v a suitable hand wheel 68 is fixed to the rod 55,

whereby said rod may be conveniently rotated.

It will be understood from this description that by rotating the rod 65, the member 9 and the rods l5 may be vertically moved to adjust the form I! relative to the spindle l and the drum 1 l8 and thereby position said form in vertically at right angles to the vertical pin or rod 22.- The other end of this rod 26 is rigidly connected by means of the clamping device 21 with a tubular rod 28. To this rod at one of its ends a supporting bracket 29 for an electric motor 30 is rigidly connected as at 3|. The other end of the rod '28 carries a supporting bracket 32 for thegear housing 33.

The vertically positioned drive shaft of the "motor 30 has a belt wheel 34 fixed to its upper 1 end and connected by drive belt 35 with a belt wheel 35 on the lower end of vertical shaft 3?,

which is suitably mounted in a depending bearing 33' on the. gear housing 33 and above theelongated housing structure 38 enclosing said Oneside wall of this housing structure has a lateral projection 39 connected with rod 28. The upper end of shaft 31 is provided with a pinion 48 in constant mesh with the gear 4| mounted in housing 33 upon dliv.-

The housing 33 is formed with an upwardly and laterally extending arm 43 upon which there is rigidly fixed a horizontally disposed supporting member 44. vOn each end of this supporting member vfreely rotatable vertically spaced apart feed belt sheaves or wheels 45 and 46 respectively, are suitably mounted. The corresponding sheaves 45 and 46 are engaged by the endless vertically spaced apart feed belts 4?.

To the vertical shaft 42 and immediately below the plane of'the lower edge of the drum l8,.a

cutting or trimming wheel is fixed. While various means might be provided for driving the feed belts 41 and rotating drum l8 and form H from-the motor 38, we preferably transmit the driving power in the following manner.

7 Above the cutter 48 vertically spaced apart drum engaging members 49 are fixed to the shaft 42 and between these members a drive wheel 59 for the endless belt 5| is also fixed on said shaft. This drive belt is engaged with a similar'driving screw and the bracket arm 51 on the gear housing 33, a suitable form of spring 58 is interposed. It will be evident from this construction that by adjusting the screw 56, the spring 58 may be properly tensioned to regulate the pressure engagement of roller 55 with the periphery of the cutter wheel 48.

While any preferred means may be employed for controlling the supply of operating current to the motor 30, we preferably provide the tubular rod 68 having a horizontal lower end portion 6| fixed in the arm 43. The current supply wires to the motor, indicated at 62, extend through the tubular rod 28 into the lower horizontal end SI of the rod 58 and then upwardly through the vertical portion thereof to a suitable hand operated switch indicated at 63, mounted on the upper end of said rod. This rod provides a convenient means whereby the cutting and feeding mechanism with the drive mean therefor may be bodily swung as a unit about the axis of pin or rod 22 into and out of operative relation with the drum I8. However, it will be understood that we may also use a pedal operated or other form of manual control switch for the operating motor if desired.

Having now described the several mechanical features of the apparatus, its operation will be understood as follows.

Beforevmoving the cutting and feeding mechanism into operative relation with the drum Hi, the skirt, dress or other garment is draped upon the form H with its lower end portion circumscribing thewall of the drum I8. ance with the desired predetermined length of the garment after trimming, the hand wheel 88 is then operated to vertically adjust the form ii relative to the drum l8 and cutter 48, in the manner above described and properly position the lower edge of the garment with respect to said cutter. The operator now swings the trim ming and feeding assembly into operative position as shown in the drawings, so that the mem here 49 will exert frictional pressure against the vertical drum wall, it being understood, of course, that such frictional pressures are applied through the interposed fabric material.

Current is now supplied to the motor 3!], and rotation is transmitted through the drive belt 35 and gearing 40, 4| to thecutter wheel shaft 42. This shaft transmits rotation to the belt drive wheel 50, which in turn drives the vertically spaced feed belts 41. The members 49 also driven through the shaft 42 transmit ro-' tation to the drum I8, and through the connecting rods l5 to the form l1. As the form is thus rotated with the drum, the folds of the garment material, in advance of the cutting member 48 are engaged by the feedbelts 4'! which press the same against the periphery of the drumwall and smoothly feed the dress or skirt material between the cutter wheel 48 and thefdisk 55.. It will be wheel 52 arranged between and secured'to the sheaves 46 engaged with the feed belts 41. p

Upon the inner side of the gear housing 33, a horizontally disposed lever 53 i pivotally mounted intermediate of its ends, as at 54. One end of this lever carries a pressure roller 55 freely rotatable about a vertical axis and disposed in the plane of the cutting or trimming Wheel 48. The other end of this lever 53 carries an adjustable screw 56 and between one end of this understood that as the drum [8 and form I! are 'rotatably. supported on anti-friction V bearings, said drum and form will be easilyrotated by the members 49. It will further be appreciated that such a machine is capable of operation at Very high speeds so that it is particularly desirable for large scale factory production of accurately trimmed garments.

In the drawings, we have illustrated a type of trimming'cutter 4B which produces a serrated or pinked edge on the garment. However, itisapparent that if desired, various other types of cutters might be used. t

In accordassign Further,.while we have herein disclosed a practical embodiment of our present invention, which in actual service has proved to be very satisfactory and highlyemcient, it is, nevertheless, to be understood that in so far as the essential features thereof are concerned, they might also be exemplified in various other alternative structural forms. Accordingly, we reserve the privilege of resorting to all such legitimate changes in the construction and relative arrangement of the various elements as may be fairly comprehended within the scope of the appended claims.
