of which the following is a specification,

reference being had therein to the accompanying drawing.

The object of the present inventlon is the provision of means for facilitating the wrapping of a bundle without the necessity of using a st-ringtor other binder.

. Another object of this invention is the production of efficient means for crimping the ends of the paper while wrapping the same around the bundle, whereby the paper will be firmly held upon the bundle.

Still another object of this invention is the production of efiicient means for placing and holding the article to be wrapped within the machine.

With these and other objects in View, this invent-ion consiststof certain novel constructions, combinations and arrangements of parts, as will be hereinafterf fully described and claimed.

Fig. 7 is a transverse section through the. machine showing the construction of the cutting knife. Fig. 8 is a transverse section through the paper roller and supporting shaft showing the construction of the rod used in connection therewith for preventing the rotation of the shaft in one direction. Fig. 9 is a detail perspective of the connecting means for the shaft which supports the paper roll. Fig-1O is a perspective view of the bundle after the same has been wrapped. Fig. 11 is an enlarged longitudinal sectional view of the wrapping frame showing the cuttingknife attached thereto. Fig. 12 is .a perspective 7 view .of a port-ion of the pair of gripping members showing the same drawn apart or in an unassembled position. Fig. 13 is a detail perspective of the paper gripping controlling arms showing the means for limiting the swinging movement of one portion upon the other. Fig. 14 is a transverse sectional view through the paper gripping members showing the manner in which the paper is folded along the edge of the bundle.

Referring to the drawings by numerals l designates the frame which is preferably supported *by means of integral feet 2, and this frame carries at its upper end a pair of upwardly extending arms 3. A paper roller 4: is supported between the arms 3 upon a shaft 5. The frame 1 curves upwardly and connects with the longitudinally extending bars 6 of the frame which are supported by the top of the arms 3. A shield or hood 7 is carried by the upper end of the frame 1, and has one end thereof secured to the frame ;by means 'of a rolled edge 8 fitting under jthe transverse bar 9 which constitutes a hinge for the hood 7. The frame 1 is provided uponthe top thereof with a central, transversely extending bar 10 and near the ,lower end of the top of the frame, the same 5 is also provided with a transversely extending bar 11. A hanger bar 12 is suspendedv from the central transverse bar 10 and this hanger bar supports a shield 13 which shield Eis adapted to cooperate with the" wraproller in section. Fig. 5 is a fragmentary f fshield 13 is braced by means of rods 14: Zwhich rods' depend from the transverse bar :11 and are connected to the front of the ping mechanism hereinafter described. The

shield 13. It will therefore be obvious that the front of the shield 13 will be yieldably supported in view of the fact that springs 15 are placed upon the rod 14. A pair of shafts 16 are carried by the frame 1, and

'esch of these shafts carries a drive pulley 1 The inner end of each of the shafts 16 is provided with a head 18. These,drive pulleys 17 are driven by means of pulleys 19 which are carried by the shaft 5 above described. A belt 20 connects the

pulleys

17 and 19. V

A plurality of. collapsible arms 21 are carried by each shaft 16 and the outer ends of these collapsiblearms are connected to the collapsible sections 22 of the paper clamping means. There are preferably four arms 21 employed, two of which are con-- I "nected to each section so that when the shaft bundle before being wrapped. The paper illustrated in Fig. 3. Crimpigg r is drawn around the outslde of the upper section and clamped between the adjacent edges of the collapsible sections at the point marked at in Fig.3. The crank 44 is then turned :}:'Of a turn thereby forming a pocket for the goods to be wrapped.

A table 23 is hinged to the frame 1,.directly below the paper roller.4, and extends artly-over the collapsible sections 22 as is members 24 are pivotally secured to the ame 1, by means of a rod 25 and the free ends of the crimping members 24 are yieldingly supported by means of springs 26. These springs are preferably formed of two loopsections. These crimping members 24 are substantially semicircular in cross section and as the paper from the roller 4 passes into the crimping members 24, the edges will be rolled under the table, thereby allowing the same to fold over the edges of the bundle which is being wrapped.

Theshaft 5 is provided with a pair of ratchet casings 31 which tightly grip the aper roller 4. Ratchet pawls 32 are carried y the shaft 5 and work in sockets 33 formed inthe shaft 5. It will be obvious that as theshaft 5 .is rotated clockwise the ratchet pawls 32 will engage the ratchet casing 31 and rotate the paper roller whereend with a handling knob 36 and at the.

other end with a stub nut and washer 37.

The knife 30 is rovided upon its upper 'edge with a lura ity of sharpened teeth 38 and this kni e, 30 is supported upon links 39having their lower ends carried byears 40 which ears are su ported upon the plate 41 of the frame 1. it will be obvious that as the knife 30 is shoved inwardly the same will rise upon the links 39 thereby pressing the sharpened teeth 38 against the paper and severing the same from the roller. The frame 1 is rovided upon its rear with an opening 42 or allowing the bundle or goods which is desired to be wrapped to be placed within the pocket formed by the paper. The bundle may also be ejected or removed from the frame through the same open ing 42.

One of the shafts 16 is provided with a coil spring-43' which spring presses against one of the heads 18. A crank 44 is also carried by the last-mentioned shaft 16 for allowing the same to operate the machine when it is desired to wrap the article.

When it is desired to remove the bundle, the

crank 44 will be drawn outwardly thereby withdrawing the

heads

18 and 22 from the end of the bundle and allowing the bundle to be removed from the machine.

From the foregoing description it will be obvious that .a very simple and eflicient de-. vice has been produced whereby the bundle may be easily and conveniently held and the same wrap d efiicienstly after being once placed witin the machine. Each of 'the

pulley wheels

17 and 19 are notched upon their periphery so as to allow the belt to be easily placed upon and removed from the wheels when it is desired to do so.

The shield 13 as stated above is suspended from the central transverse bar 10 throughthe medium of the hanger bar 12 which consists of a pair of sections connected at their ends by means of a turn buckle 12.. By the use'of this turn buckle 12, it will be obvious that the shield 13v rolled upon the bundle '28 The wrapping of the bundle in the manner as above stated is made possible in view of the fact that the bundle supporting blocks firmly engage the ends of the bundle and the paper is allowed to extend upon each side of said bundle.

From the foregoing description, it will be obvious that as the pa er is fed over the bundle the ends thereo will be so crimped as to take the desired shape after passmg 'around the bundle by first being held in eng ment with the crimping jaws 22.

y carefully considering Fig. 3 of the drawing, it will be obvious that as the arms 21 are rotated to the left,-the links 21 will be straightened in alinement with the arms 21, thereby causing the collapsible sections to be brought tightly together at their adjoining ends. As long as the operating shaft is operated ,in the direction abovestated, the paper will be firmly grippedby the edge of the jaws as illustrated at X in Fig. 3. If, however, the shaft is rotatedin,

the opposite direction after the bundle has been once rotated, of course, the arms 21 will cause the links 21' to be'released from their alined position and again assume a collapsedposition, and allowing the adjoining edges of the gripping sections 22 to be released from each other. I

As is illustrated in Fig. 12, the head 18 is provided with a beveled face 50 for allowing the paper to be easily removed from the head 18 and gripping members 22 when the head 18 is drawn from the edge of the paper wrapped around the bundle. This feature is clearly illustrated in Fig. 14. The paper gripping members 22 are supported by arms 2]. as previously described which arms are integrally connected together. The arms 21 are keyed to the axle 52 formed upon the shaft 16. The outer face of the arms are engaged by means of a roughened washer 54, which washer is in turn engaged by means of a nut 55 having a milled or roughened face engaging the washer whereby the nut will firmly hold the member 51 in its proper place upon the stub shaft 52. The arms 21 are provided near their outer ends with angular, laterally extending members 56 which are adapted to engage the sides of the links 21' for limiting the pivotal movement of said arms in one direct-ion. Each of the links'21 is also provided with a depending finger 57 which is also adapted to engage the angle members 56 carried by the arms 21 for limiting the pivotal movement of the link 21 in the opposite direction. Of

course, it should be understood that when the paper is cut the cut edge is still a dis-- tance from the bundle and the crank 44 is rotated until theend of the paper has reached the bundle. The free end of the paper carried by the roller follows the cut edge of the paper wrapped around the bundle and then the operation of the crank in discontinued and operated in the opposite direction, thereby releasing the edge of the paper from the paper grippersand allowingthe bundle to be removed from the machine, and the edge of the paper to be released from the grippers. Of course, the edge of the paper for receiving a new bundle may also be attached as previously described.

semicircular guards 29 are carried by each side of the frame 1 and are adapted to engage the edge of the paper carried by the roller for guiding the same directly to the paper crimpers. A stationary table 29 is carried by the lower edge of the semicircular guards 29, and this stationary table is adapted to protect the paper as the same is first cut by the knife 30. The inner ends of the semicircular guards 29 are much lower than their outer ends so as to guide the paper directly near the knife, and facilitate the cutting thereof. The feet 2 of the body 1 are provided with apertures 58 through &

holding the wrapping machine upon a support.
