GEORGE H. PEMBROKE, OF NEW BRUNSWICK, NEW J ERSEY, ASSIGNOR 'IO MARCUS H. HORTON, OEBROOKLYN, NEW YORK.

PAPER-FASTENING MACHINE.

Application filed December 31, 1912.

To all whom it may concern:

Be it ,known that I, GEORGE H. PEMBROKE, a citizen of the United States, residing at New Brunswick, MiddleseX county, in the State of New Jersey, have invented certain new .and useful Improvements in Paper- Fastening Machines, of which the following s a full, clear, and eXact specification.

My invention relates to improvements 1n means for fastening and binding together sheets of paper or. analogous articles by means of an eyelet, and the same has for its object more particularly toprovide a simple, eflicient and reliable apparatus which is com pact in form, simple and positive in operationand not liable to get out of order.

Further said invention has for its object to provide a machine for the purposes specified which is designed to receive a series of fastening members mounted upon a suitable support, and then feed the same, one byone, to the driving mechanism whereby .the sald fasteners are caused to secure the paper together.

Further said invention has for its object to provide a machine in which the fastener in position tobe driven will remain properly in such position until it is actually driven, and will not feed another fastener into operative position until the first fastener has been actually driven into the paper or otherwise disposed of.

Further said invention has for its object to provide a machine for the purposes specified which shall be compact in form, simple in construction and so arranged that access may be had to the interior thereof for the purpose of adjustment and cleaning.

To the attainment of .the aforesaid objects and ends my invention consists in the novel details ,of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in theclaims.

In the accompanying drawings forming a part of this specification wherein like numerals of reference indicate like .parts, Figure 1 is a side view showingone form of machine constructed accordingto and embodying my said invention; Fig. 2 is a vertical section taken substantially on the line 22 of Fig. llshowing the machine with a fastener in posit on ready to be driven ,Fig. 3 is a similar view showing the fastener d ven q ust about to e riv ed to fa t n Specification of Letters Patent.

eyelets in position thereon, Fig. 7 is a detail perspective vlew showlng the construction of the lower ends of thechuck jaws.

In said drawings 10 designates the ma chlne as a whole comprising a base 11 from which projects a standard 12. 13 denotes a cylindrical section which is rigidly secured to thestandard or upright 12 by screws 13 13 Vithin the easing 131s secured a head 11 having a flange 15 thereon resting upon the upper edge of the casing 13. The head 14 is provided with a circular opening having its inner lower portion beveled at 16.

17 denotes a thumb screw which extends through the upper end of the upright or standard 12 and engages the ,inclosed portion of the head 14 whereby to secure said head firmly in position within the top of the casing 13 and maintain the operating parts within said casing duly in position therein.

18 denotes asha-ft which is disposed within the opening in the head 1 41. The said shaft 18 is provided at its upper end with an operating head 19, and at its lower end with a reduced portion 20.

21 denotes a longitudinal groove provided in the shaft 1S,through which extends a pin 22 having its inner end secured to a tubular section :23 slidably mounted within the shaft 18. I i

The head 1 1 is provided .at its forward portion with a vertical recess 24 in the base of which is vertically secured an adjusting screw 25 whose upperendserves as a support for the forward end of the pin 22 carriedloy the tubular section 23, and to limit the downward vmovementof said tubular section within the shaft 18.-

2,6 denotes a yoke secured in the upper side of the head 14 whichemhraees the pin 22 and serves to limit the upward movement of the tubular section 23 when the shaft 18 and head 19 are drawn upwardly.

27 denotes a support which is substantially circular in outline and secured to the lower end by means of a screw 27. The said support 27 is provided at its opposite sides with

vertical recesses

28, 28 within which are vertically disposed

jaws

29, 29 which are pivotally mounted upon

pins

30, 30 carried by said support. The upper ends of said

jaws

29, 29 are beveled in order to engage with the beveled surface 16 of the head 14, and the lower ends of said jaws 29 are arranged at substantially right angles to the vertical portions thereof and have their opposing edges recessed to form a socket for an eyelet, and also a passage for the rod or support for the eyelets.

31 denotes an annular member or carrier disposed within the lower end of the casing 13 and provided at its opposite sides with

pins

32, 32 which extend through

recesses

33, 33 provided in the casing 13. Upon the outer opposite sides of the casing 13 are secured

guide plates

34, 34, and upon the outer sides of the casing 13 but within said

guide plates

34, 34 are secured

pins

35, 35.

36, 36 denote springs secured at their upper ends to the

pins

35, 35 arranged upon the outer side of the casing 13, and at their lower ends to the

pins

32, 32 secured to the annular member or carrier 31.

The annular member 31 has its inner surface rounded at 37 to act as a cam when the rounded portions of the

jaws

29, 29 are brought into contact therewith and serves to cause the ends of said jaws to be guided into engagement with each other and to embrace the eyelets and the rod therefor.

The base 11 is provided at its center with a socket into which is fitted an anvil 38 having an upwardly projecting pin or stud 39 and an annularly grooved base 40 surrounding said pin or stud 39 which serves to turn the lower edge of an eyelet outwardly when the eyelet is forced thereon by means ofthe

jaws

29, 29.

The operation of the apparatus is as follows: The eyelets for use in connection with the machine are mounted upon a rod 41 which is provided at its upper end with a ring or finger portion 42 adapted to rest upon the upper end of the tubular section 23 in order to prevent the lower end of said rod coming in contact with the pin or stud 39. The said rod 41 is of such diameter that the tubular portions 43 of the eyelets will slide freely thereon while the lower end of the rod 41 is provided with a slight bur or head of such size as to be just sufficient to prevent the tubular portion of the eyelets 43 passing freely thereover. By this means the lowermost eyelet upon the rod 41 will be held duly in position upon the said rod ready for driving.

In order to drive an eyelet, the shaft 18 must first be drawn upwardly by means of its head 19 until the pin 22 on the tubular section 23 within said shaft 18 engages the yoke 26 and prevents further movement of said shaft 18 and tubular section 23. At the same time the upper beveled ends of the jaws 29 will be brought into contact with the inner beveled edge 16 of the head 14, and cause the lower ends of the jaws to become separated and assume the position indicated at Fig. 4. As soon as the lower ends of the jaws 29 have become thus separated the rod 41, with the eyelets thereon, will be permitted to drop sufficiently to allow the lowermost of said eyelets to be brought into position directly below the lower edges of the horizontal portions of the

jaws

29, 29 whereupon said jaws are caused to be brought together with the succeeding downward movement of the shaft 18, and con nected parts due particularly to the en gagement of the rounded portions of the

jaws

29, 29 with the inner rounded surface of the annular member 31. WVith this movement of the shaft 18, and the parts carried thereon, the apparatus will be in the position indicated at Fig. 2.

In order to drive the fastener into the paper or other article to be joined together it simply becomes necessary to strike upon the surface of the head 19 a sharp blow with the hand and thereby cause the shaft 18 and its reduced portion 20 together with the support 27 to be driven downwardly and the annular member 31 to be carried downwardly at the same time in opposition to the tension of the supporting

springs

36, 36.

As soon as the lower edge of the tubular portion of the eyelet strikes the grooved base 40 of the anvil 38 the lower edge of said tubular portion will be flared outwardly and the eyelet caused to clench the paper or material between the flange 43 of said eyelet and the newly formed flange at the lower edge thereof.

Should the machine for any reason fail to rivet the eyelet with the first impact the parts will be caused to resume the position indicated at Fig. 2, that is to say, the lowermost eyelet on the rod 41 will remain in position below the horizontal portions of the

jaws

29, 29 and prevent the feeding of the succeeding one. The shaft 18 and parts carried thereon may thereupon be forced downwardly again by a sharp blow with the hand upon the upper surface of the head 19, and the eyelet riveted.

In order to bring the succeeding eyelet in position for driving it is first necessary to raise the shaft 18 by means of its head 19, as first above described, to separate the lower ends of the jaws to permit the entire stack of eyelets upon the rod 41 and said rod to drop the required distance.
