MACHINE FOR APPLYING REENFORQEMENTS T0 BAGS OR THE LIKE.

Application filed June 18, 1927.

This invention relates more particularly, but not necessarily, to machines for applying stiffening strips between the outer walls and linings of hand bags or the like, such, for example, as the well known form of drum shaped hat hand bags. lVith respect to hat hand bags considerable difliculty is experienced in inserting stiffening material, such as a strip of cardboard, between the outer wall and the lining, especially where the lining has been already incorporated with and sewed into the bag. In such case usually a slit is provided in the lining and the stiffening or reenfcrcing strip inserted therethrough, sometimes in one piece and sometimes in two pieces.

One of the objects of the present invention has therefor specifically in view a machine which will insert or enable the insertion of a stiffening strip into hat hand bags, such as referred to, although the invention has a broader aspect, for it is capable of general use in the arts where stiffening or reenforcing material is to be applied to containers, bags,

boxes, etc, whether the article be cylindrical,-

rectangular or some other shape.

Other objects of the invention are to provide efficient, economical and practical means for applying reenforcements to bags or the like, preferably in the form of a machine having a mandrel for receiving the article to which the reenforcement is to be applied.

These being among the objects of the present invention, the same consists of certain features of construction and combinations of parts to be hereinafter described and then pointed out in the claims, reference being had to the accompanying drawings illustrating a preferred embodiment of the invention, and in which Figure 1 is a sectional side elevation of the machine provided with power means for operating it;

Fig. 2 is an enlarged sectional side elevation of the mandrel and concomitant parts;

Fig. 3 is a vertical central section of the machine showing the parts in position at the end of the forward movement;

Fig. 4c is a section of some of the parts in the same position, taken at right angles to Fig. 3;

Fig. 5 is an elevation as viewed from the interior of the machine, partly in section, and showing a container or bag placed on the mandrel;

Serial No. 199,847.

Fig. 6 is a transverse section showing how the guide nose for the strip of reenforcing material is placed with respect to the bag or container, and

Fig. 7 is a detail of the outer part of the guide-nose.

Referring to the drawings, a suitable sup porting frame 10 is provided which receives a tubular support 11 held rigidly to the frame by a set-screw 12. Preferably the frame 10 1s upright and the tubular support 11 horizontal, and on one end of the tubular support there is mounted a stationary head 13. The position of this head is not essential, except that it is preferred that it stand vertical at the end of tl e support 11.

The head 13 is fixed to the support 11 bv means of a set-screw 14, and at the center of the head 13 there is fixed a pivot shaft 15 by means of a set-screw 16. On the other end of the shaft 15 a complementary head 17 1s rigidly fixed by means of a set-screw 18.

As shown more clearly in Fig. 3 the two

rigid heads

13, 17 are directly opposite one another, and are preferably of identical con struction. Preferably the

heads

13, 17 are formed conjointly in the outlines of a cylinder and they constitute a mandrel over which the bag or other article to be reinforced or stiffened may be placed.

As shown more clearly in Fig. 3 the

rigid heads

13, 17 are respectively provided around their peripheries with guide-

flanges

19, 20, the flange 19 being provided with a rii'ig or plate portion 21 and the flange with a similar portion 22, these ring or plate portions being rigidly fixed to opposite sides of the

heads

13, 17 by means of counter-sunk set-screws 23. Generally, but not necessarily, the contour of each

head

13, 17 is circular and in such case each guide-

flange

19, 20 follows the circular contour and is spaced a slight distance away therefrom so as to provide opposite and concentric guideqvays 24-, 2 1. These guide-ways open the one towards the other, that is, towards the central plane of the mandrel, so as to receive and guide a strip of flexible reinforcing material.

Each of the

heads

13, 17 has cut into its peripheral portion a gap 25, and the two gaps are opposite each other. These two gaps will be referred to as one gap, as opposite the gap 25 there extends a guidenose 26 from the guide-ways 24, 2 1 This guide-nose facili tates the leading of the strip of material to he wall of the bag or container which is to be reinforced, and preferably the guide-nose 26 extends tangentially of the mandrel, if that be circulan In any event it preferably diverges slightly from the mandrel.

The guide-nose 26 preferably comprises

innor metal blades

27, 28 and

outer metal blades

29, 30, which are suitably rigidly fixed to the mandrel, to form between them a directional extension of the guide-ways 24, 24. While there are preferably four of these blades producing a sort of duplex nose, the combined blades will be referred to herein as a guidenose, the

blades

27, 29 at one side being separated from the

blades

28, 30 at the other side of the mandrel by the preferred special distance between the two

heads

13, 17 of the mandrel.

Mounted in the tubular support 11 is a shaft 81 which may be employed as a shaft driven from a motor 32, as shown in Fig. 1. The motor shaft is provided with a pinion 34 which meshes with a large gear-wheel 35 loosely mounted on the shaft 31. Gpposuig the gear-wheel 35 is a friction-disk 36 which is rigidly secured to the shaft 31 so that one face of the gear-wheel 35 may be brought in frictional contact with the friction-disk 36 by means of a helical pressure spring 3? fixed at one end to the shaft 31 and bear ng at its other end upon a portion of the gear-wheel 35.

On the inner end of the shaft 31 there is ed a pinion 38, which turns in a suitable recess in the mandrel head 13,. and in the same recess there is arranged a large gear-wheel 89, with which pinion 3S meshes. and which is mounted loosely on the mandrel shaft 15 A large ratchet wheel 40 is firmly attached to one face of the gear 39, while between the ratchet wheel 40 and the other mandrel head 17 there is loosely placed upon the shaft 15 sleeve or hub 41 of an arm 4 A sweeping motion may be prod iced on the arm 42 so as '0 move it around the pivot shaft 15 and between'the

h ads

13, 17.

A pawl 43 is pivoted to the swinging arm 42 intermediately of the length there. f, and the toe of the pawl is adapted to engage the teeth of the ratchet wheel 40. A. spring; 44 fixed to the arm 42 at one end bears at its opposite end upon the toe portion of the pawl 42 with a view to forcing the toe of the pawl into ongaeement with the ratchet teeth.

means 45 located at the outer end of the arm 42, the same extending laterally of the arm. Such means 45 are a t engage one end of a strip 46 of re material. as cardboard, for exan'iple, and such grasping means preferably comprise a fixed jaw 47'extending rigidly from the arm 42 and a movable jaw 48 which opposes the said fixed jaw. The movable jaw 48 is mounted on a pivot pin 49 on the arm and is provided with a heel-member 50 (shown clearly in Fig. 4), between which heel and a suitable seat of the arm 42 an expan ion spring 51 is arranged, the to dency of which is to close the jaw 48 towards the jaw 47 and to grasp or grip the reenforcing materil 46. The aw 48 is also provided ith a finger-piece 52 constituting manual means for opening the aw 48 in oppoition to the expansion spring 51.

The described machine is adapted for either power operation or inaniial operation. The power operation thereof will first be described. When itis desired for example, to apply reenforcing material to a bag 53, usually com} osed of flexible material, the bag is placed vcr the

mandrel

13, 17, as shown more clearl in Fig. 5. if a hat hand bag of a certain construction is to be reinforced it would have a peripheral wall or band portion 54 of leather or leather-like material and a lining 55 of thin textile material to give an i erior finish to the bag. After the fabric lining has een incorporated with the bag and sewed into its material, it is usually not an easy matter to insert stiifening material in the form of a strip 46 betwen the outer wall 54 of the and the lining 55. In such a case a transverse slit is l I} as defined by the edges 56, 5? of the SLll: see he upper part of F g. 5\.

nefore plac- 'L ing the bag on the mandrel a strip of stitienmg lilZtt8"-Ell 46 is 8281i threaded into the uide-wr s 24, 24 around the mandrel until u I u u forward end thereof is within the guidethe nose 26 the rear end there-or b'Ell'lg in position to be engaged or grasped by the jaws '47. 48,

which are caused to engage the material as shown in Fig.3. 5. The bag to be reenforced having been placed over the mandrel, it is so po '.tioi:ied as to enable the guide-nose 26, the end of tne material 4-6 held thereby, to be 1 "5 he i: in the lining at 56, 5 t positioned acent with the forward l ietween the wall 4 and tl The operator .or lies firm hon: of the bag and sets the iootor 32 in operation. The shat 31 will now be driven, which will caush meshing pinion 38'and SI i881 39 to ota'e the ratchet wheel 40 in the direction of the arrow Fig. 5, tiereby pushing the stiffening strip 46 along the guide-ways 24. 24 and through the 'Qlc-nose 26, and while the operator is holding; the bag, the strip will be fed continuously betw een'tho outer wall 54 andthe linin z of the bag. lt will be seen that the atchet'whcel 40 at this time is in constant engagement with the pawl 43 and causes the arm 42 to sweep around shaft 15 with a continuous progressive pushing or feeding aclion.

Means are provided for stopping the ad vanciug nioven'ient of the arm 42. and h ce t io strip 46 and also means for tie strip 46 from the jaws 4S whenthe eft or made in the linilOQ means preferably work. automatically and will now be described. A crosspiece 58 at one end of the transverse gap 25 in the mandrcl is attached to its opposite ends to the

heads

13, 17, as shown more clearly in Figs. 1 and 3. This cross-piece constitutes a forward stop for the arm 42 and also means for opening the

jaws

47, 48. It will be seen from Fig. 4 that when the arm 42 reaches the end of its forward movement it abuts against the stop 58, and simultaneously the said stop bears on the heel-member of the movable jaw 48 and compresses the spring 51, thereby opening the aws47, 48 and releasing the reenforcing strip 46 therefrom. The entire strip will then be inserted between the outer wall and the lining of the bag, and the machine may then be set so as to start all over again and feed another strip through the same slit in the bag, but in contrary direc tion to the strip first inserted.

lVhen the arm 42 reaches the end of its forward movement as restricted by a stop 58, a lateral shoulder or projection 60 on the rear end of the pawl 43 is broughtinto engage ment with a release pin 59 which is inserted in a hole in the head 13 so as to have a fixed position, although such pin is removable. This abutmentagainst the pin 59 disengages the toe of the pawl 43 from the tee h of the ratchet 40, and as the material 46 has been released from the jaws and the pawl 43 disengaged from the ratchet, the arm 42 and concomitant parts may be returned to rearward position. However, the rear end of the pawl 43 is provided with a notch 61 into which snaps the bent end 62 of a plate spring 63 fixed to the swinging arm, which snapping engagement is brought about by the outward movement of the pawl caused by the release pin 59. The plate spring 63 maintains the pawl 43 disengaged from the ratchet until the arm 42 is moved by hand back to sta ting position. At the starting position, the head 13 is provided with a throw-pin or back-stop 64 inserted through a hole in said head, and which engages the toe of the pawl 43 when the arm has been returned to its original or starting position. This acts to reengage the toe of the pawl 43 with the teeth of the ratchet 40, and the same also disengages the end of the plate-spring 63 from the notch in the pawl, all as shown in 5. Another reen forcing strip n'ia-y now he placed on the mandrel and attached to the jaws of arm 42 for the forward movement of such strip. The head 13 may be provided with a series of holes 65 for a difi erent positioning of the throw-pin or back-stop 64, for a shorter forward movement of the arm 42, for inserting shorter lengths of stiffening or reenforcing material.

Preferably the head 13 is provided with two or more holes 66, 67 and head 1'? is provided with similar, coinciding

holes

68, 69.

It will be seen that when the tubular support 11 is entered into the hole 66 and the head 13 rigidly fixed to said support, that larger bags may be accommodated on the mandrel than when the tubular support 11 is fixed in the hole 67. When support 11 is fixed in hole 67 the machine may be only operated by hand for stiffening smaller bags. In that case longer screws 70 are used to connect gea 39 and ratchet 40, and these are screwed into suitable holes in head or frame 13 to hold the gear and ratchet rigidly. The

holes

68, 69 are provided in head or frame 17 so that the machine may be made left handed by fixing support 11 in either of them. As shown in the drawings the machine is right handed.

When the support 11 is fixed in either hole 66 or 68, and, if then, "the stilfening or reenforcing material is to be applied by hand, that without the use of the motor 32, it is neces sary to tighten up the set-screws 71, shown in Fig. 1, against the shaft 31, as shown in 3, thereby holding shaft 31 rigidly within the tubular support 11. This fixation of shaft 31 will also hold the

gears

38, 39 and the ratch t wheel 40 stationary. To insert a stiffening strip 46 by hand, the operator grasps one end of the strip 46 by the jaws of the arm 42, after the strip has been threaded into the guide-ways of the mandrel, and places the bag upon the mandrel so as to insert the other end of the strip and the guidenose 26 through the slit in the lining of the bag. He now takes hold of the bag and lining at apoint opposite the nose 26 and the material 26 for a short distance through'the guide-nose, and then moves the bag back a similar distance, and continues this manipulation step by step until the stiffening strip 46 is fed by a step by step movement through between the wall 54 and the lining 55 of the bag. In some cases this hand method is desirable, although ordinarily speaking the power method is better, because quicker and more expeditious in turning out the work. It will be seen that as the operator feeds the strip 46 forward step by step that the strip pulls the arm 42 around and the toe of the pawl 43 rides idly over the teeth of the ratchet wheel 40. The toe of the pawl by engagement with the ratchet teeth will prevent retrograde movement of the stiffening strip 46. lVhen the arm 42 reaches the end of its step by step advance movement, the operation to automatically disengage the pawl from the ratchet, to disengage the grasping

arms

47, 48 from the strip, etc., are the same as when motor power is used.

It is obvious that the described and illustrated invention is susceptible to a wide range of modification without departing from the spirit of the invention as expressed by the scope of the appended claims.
