HOSE TOE-PROTECTOR-FORMING MACHINE.

Specificat on of Letters Patent.

Application filed July 10, 1911. Serial No. 637,844.

I To all whomit may concern:

- parts seen looking in Be it known that I, Jason ltanz, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Hose-Toelrotector-Forming Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aceom panying drawings, forming part of this specification, in which- Figure 1 is a side elevation of a machine of my improved construction, parts thereof being shown in vertical section. Fig. 2 is a view of the blank or section of material 'from which a hose toe protector is formed by my improved machine. Fig. 3 is a side elevation of a hose toe protector formed and shaped by my improved machine. Fig. 4 is an end elevation of the machine looking in the direction indicated by Fig. 1. Fig. 5 is a plan view of a portion machine. Fig. 6is a vertical section taken .on the line 6-6 of'Fig. 5. Fig 7 is an elevation of the the direction indicated by the arrow 7, Fig. 5. Fig. 8 is an enlarged sect-ion taken on the line 8-8 of Fig. showing a portion of the fornnng means.

Fig. 9 is an elevation of a sliding support or head which occupies the packing tube or housing into which the completed protectors are packed.

This invention-relates to a machine for forming hose toe protectors, and packing the same into tubular containers.

Thchose toe protector formed by my improved machine is preferably made from thin material, such as paper, and is pressed into the form ofa cup or a short tube closed at one end, and when in use said hose toe protectors are positioned on the great too beneath the hose for the purpose of preventing the rapid wear of the hose at the point occupied by the forward portion of the great big toe.

he object of my invention is to provide a simple, inexpensive machine, which can be operated with little power, and which will very rapidly form the hose toe protectors from circular blanks of thin niaterial, wliich are automatically fed to the machine in any the arrow at 1 andthe completed protectors in nested form within suitable tubular containers.

To the above purposes my invention cons sts in certain novel.features of construc tion and arrangement of parts hereinafter more fully described and claimed.

Referring by numerals to the accompanymg drawings, which is fixed a pair of upright brackets 2 Patented Ju1y2,1912.

1 designates a suitable baseon and 3, which lattenare provided at their upperends with-'alined bearings 4 and 5, Mounted to slide through the bearing 4 is a rod 6, and a corresponding rod 7 is mounted to slide through the bearing 5). The adjacent ends of the rods 6 and'7 are rigidly fixed in any suitable manner to the opposite side of an upright block 8 having a vertically disposed slot 9.

Fixed on the base 1 between the brackets 2 and 3 and to one side thereof is a bracket 10 having a bearing 11 at its upper end, and j ournaled for rotation in said bearing 11 is a shaft 12, the same being disposedat right angles to the rods 6 and 7. Loosely mounted on the outer end of this shaft 12 is a 'pulley 13 and positioned on said shaft adjacent said pulley is a clutch l tof any suitable construction adapted for locking the pulley to said shaft.

Fixed on the shaft 12 adjacent the inner ends of the rods (5 and 7 is a cam 15 having a low portion 16, a high portion 17 and a shoulder 18 between said low and high portions.

J ournaled on a pin or trunnion projecting from the outer face of the cam 15 1s a roller 19 which occupies and operates through the. slot 9 in the block 8. 20 designates a sleeve positioned in front of the bearing 4, and through which sleeve the forward end of the rod (3 operates. The forward end of this sleeve 20 is in the shape of a truncated cone 21, and the. surface of this fin-ward end is provided with a series of radially disposed ribs 22.

h'lounled to slide "freely on tlicforwardend ot" the sleeve 20 is a collar 22$ provided with a longitudinally disposed slot 24, the Forward end of which extends laterally 'a. short distance asdesignated by 25. A pin or screw 20 passes is seated in the forward portion of the sleeve 20. This construction permits the sleeve 20 and collar 23 to have sliding movement relathrough the slot 24 and tive to one another for a predetermined distance, and it also permits these parts to hate a slight rotary movement relative to one another when the pin or screw 26 passes into the laterally extending portion 25 of the slot 24.

A nut 27 is screw seated upon the threaded rear end of the sleeve 20, and interposed between said nut and a shoulder on the collar 23 is an expansible coil spring 28. One end of a horizontally disposed arm 29 is rigidly fixed in anysuit-able manner to the'rear end of the sleeve 20 which arm extends rearwardly past the bearing 4, and adjustably positioned on the rear end of the arm is a plate 30 carrying an anti-friction roller 31 which travels upon the periphery of the cam 15. v

Projecting laterally from the arm 29 is a pin 32, carrying on its outer end a. roller 33 which latter normally occupies a hori zontally disposed slot 34 formed in the upper portion of a standard 35, and the forward end of this slot 34 is extended downward as designated by 36. I

37 designates a standard fixed to the base 1 in front of the standard 2, and mounted in the upper end of said standard 37 is a tubular bearing 38. Loosely mounted in the rear end of this hearing 38 is a former head 39 through which is formeda Conical opening 40, the surface of which is provided with a series of radially arranged grooves 41 adapted to receive the ribs 22 on the forward end of the sleeve 20. This head 39 normally occupies a position immediately in front of the collar 23, and formed in the outer face' of said head 39 is a series of radially arranged grooves 42, which are adapted to receive corresponding radially arranged ribs 43, formed on the outer face of the collar 23.

44 designates a U-shaped member carried by the head 39 for supporting the blanks of material X from'which the toe guards are formed, when said blanks are first fed into position between the collar 23 and head 39.

45 designates a housing in the form of a paper tube one end of which is applied to the forward end of the tubular bearing 38,

' and the hose toe protectors after. being formed by the machine are forced through the tubular bearing 38 into the packing tube 45. In order to support the forward one of the protectors when the same is forced into the packing tube 45, and to cause said protectors to nest within said packing tube a head 46 is provided which head is carried upon the rear end of a rod 47, and said rod is inserted through the packing tube 45 when the latter.v is fitted onto the tubular bearing 38. The outer portion of this rod 47 is mounted to slide in a suitable bearing 48, and fixed on said rod is a collar 49.

5O designates a bar which is arranged tov slide through suitable hearings on the" brackets 3 and 37 and projecting upward from the .rear end of this bar is an 'arm 50 the base 1. The forward end of the rod 6 is provided with a top 6 of rubber, leather or analogous material. During the reciprocation of the yoke 8 its lower end has sliding bearing between a-pair of longitudinally disposed ribs -1 formed on the base 1 between the uprights 2 and 3.

The operations incident to the formation of hose toe protectors with the machine just described is as follows: A belt is applied to the pulley l3 and when the clutch 14 is thrown in the shaft 12 and parts carried thereby are rotated in the direction indicated by the arrow a,-Fig. 1. The roller 19 moving from its lowermost point upwardly and rearwardly moves the yoke 8 together with the rods 6 and 7 rearwardly, and during this rearward movement of the rod 6 the sleeve 20 mounted on the forward end of said rod 6 will by reason of its frictional engagement with said rod be drawn rearwardly until its rear end strikes against the bearing 4. At this point in the operation of the machine, a circular section of thin material X as shown in Fig. 2 is fed into, the

spacebetween the clamping collar 23 and.

tween the adjacent faces of the collar 23 and The radially arranged ribs 43 head 39. formed on the outer face of the collar 23 will force the ed ge of the blank into the corresponding grooves 42, thereby creasing the edge of the blank. During the movements of the parts just described the roller 31 .is bearing upon the low portion 16 of the cal? 15 and-after the collar 23 has been move forward to clamp the edge of the blank,-the v cam 15 is rotatedso that a part of its high portion immediately in front of the shoulder 18 bears against the roller 31, thereby moving the same, togetherwith the plat/e30 and arm 29 in a forward direction, and as said plate 29 is igidly fixed to the sleeve 20 said sleeve will-be moved forward through the collar 23, and this movement slightly com;

presses the spring 28, thereby storing power therein. During the movements just described'thc forward portion of the rod 6 moves through the sleeve 20, and the tip (S on the forward end of said rod engages the central portion of the blank and moves the (same into the forming head 39, thereby )rradna'lly withdrawing the edge of the lank from its position between the coinciding faces of the head 39 and collar 23, which latter is held against the forming liead by the power stored in the coil spring 28. At this point in the operation the roller 31 traveling against the periphery of the cam rides over the shoulder 18 thereon, and after said roller rides beyond this shoulder, and onto the high portion 17 of the earn, the sleeve 20 is permitted to move rearwardly a slight distance corresponding Q t o the height of the shoulder 18, and at this instant the roller 33 carried by the pin-32 which has been moving forward through the slot 34 rides intothe downwardly extending forward end- 36 of said slot, thereby,slightly'moving the bottom of the fin ger 32, and plate and consequently impart-in slight rotary motion to the sleeve 20.

During this slight rotary motion ofthe sleeve 20' the laterally extended forward end :25 of the slot 2t accommodates the screw 26 which is seated in said sleeve 20, and thus the collar 23 doesnotrotate with the sleeve 20. At this point of the operation the conical forward end of the sleeve 20v has been moved forward into the -forming head 39, thereby drawing the edge of the blank X out from between the face of said dread, and the corresponding face of the coll'ar .23, which edge as heretofore described 6 is creased or corrugated by means of the ra dially disposed ribs 4.3, and corresponding radial grooves 42. The slight rotary motion in'ipartcd to the sleeve 20, just described, tends to told down the radially disposed I creases formed around the edge of the blank, and these creases are caused to enter radially disposed grooves 41 within the forming head. 'lhcse creases or folds designatcd by Z Fig. 3 have the greatest width at the extreme outer edge of the blank, and

said told or crease graduall ward the center of the bl'an' c, andtlius an approximately cup or thimblc shaped protecting device is formed, which is of such size and form as to [it snugly upon the great toe when positioned thereon. A t'ter the protecting device has-thus been formed it is I forced into the tubular bcaring 38 and as succeeding protectors are formed they are nested one within the other and are orcct forward through the tubularbearing against the head 46.

In order to permit. the nested protectors to pass into the packing tube 45 thc head 46 is gradually moved rearwardly through said decreases topacking tube by means of the pawl 53 which at the end of the forward stroke of the yoke 8 passes oil the plate 54, engages between the teeth 52 on the top of" the bar 50 and moves said bar a short distance forward, and this movement is transmitted to the rod t7 carrying the head 46, by means of the arm 50" carried by said bar 50, and engaging the collar 49. Thus the head to serves as a yielding support for the' forward one of the series of protectors packed within the tube 45, and provides means whereby said protectors aretightly packed in nested form. During the rearward movement of the yoke 8 the rods 6 and 7 move rearwardly through the bearings 4 and 5 and the sleeve 20 and arts carried thereby are drawn rearwardly y reason of the frictional engagement between said sleeve and the rod 6. .During this rearward movement the roller 33 carried by the pin 32 travels to the rear end .of the slot 34 and the pawl 53 carried by the yoke 8 moves over the top of the plate 54.

A machine of my improved construction is comparatively simple, is very compact, can be operated with little power, and very thnnble shaped hose toe protectors, an

packs the same in nested form in. suitable tubular packages.
