Application filed May 22,.

This invention relates to improvements in marking machines and the principal object thereof is to provide a machine adapted to mark successively a series of superimposed articles beginning at the lowermost.

A further object of the'invention is to provide a machine of the character above described withmeans for clamping the superimposed articles upon the work support with means for permitting the successively marked articlesto be moved from the work support or'platen upon which the articles are marked.

A further objectof the invention is to provide a novel clamping mechanism which will clamp anyedesired number of articles upon the work support.

A further object of the invention is to provide a novel mechanism for supporting the printing head which will permit the printing head to be moved from inking position to printing position while maintaii'iing the plane of the printing face in substantial parallelism with the plane of the work support. i

A further object of the invention is to provide means for normally supporting the printing head in an elevated position in termediate of the hiking mechanism and printing position.

A further object of the invention is to provide a novel mechanism. for locking the type in the printing head in such a manner that the individual type can be removed without the necessity of removing the type hold-er from the printinghead.

Other objects and features of the invention will more fully appear from the following description of the accompanying drawing and will be particularly pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings in which Fig. 1 is a side elevation of a machine particularly designed for marking gloves or other flexible articles;

Fig. 2.

The machine illustrated in the accompanylug drawing comprises a base 1 upon one end of which a work support 2 is mounted or formed integral therewith. The work support 2 extends beyond the end of the base 1 to provide a spaceto permit the provided with a printing platen .3 of relatively soft material which will not injure the type. The work support is provided with an aperture 4 of suflicient area to per- 'mit the portions of flexible articles which have been'printed upon the platen to be depressed therethrough and is provided with a suilicicntly large surface 5 beyond the aperture to enable a series of superimposed flexible articlesfiysuch as gloves, shoe uppers and the like, to be clamped thereupon.

Suitable means are provided for clamping I the superimposed articles upon the work support. The preferred means illustrated herein comprises a flat plate 7 having at its ends upturned ears 8 which are pivotally mounted upon a rod 9, the ends of which are secured to like parallel links 10 which are pivotally mounted at their lower ends upon bosses 11 extending upwardly from the end portions olthe work support.

Suitable means are provided for locking the clamping plate .7 in clamping engagement with the articles 6. In the construction illustrated herein a pair or" pawls 12 are p ivotally iounted upon the rod 9 and are provided with upwardly extending arms 13 which desirably are connected by a handle member in the form of a rod 14 so that both pawls may be actuated sin'mltaneously. The

pawls 12 engage the teeth of like arcuate ratchets 15 which are mounted upon the work support and as shown herein are pivotally supported upon suitable lugs extendingupwardly therefrom. r'irms 16 extending from the ratchets engage posts 17 projecting up\ "ardlv lromthe work support and serve to hold the ratchets in proper position.

gagement with the pile.

Springs 18 connected at their upper ends to the arms 18 of the dogs and at their lower ends to the parallel links 10 hold the pawls normally in engagement with the ratchets. By reason of this construction the clamping plate 7 can be readily raised to permit the insertion of articles to be. marked by grasping the handle member f and swinging the same to the left to disengage the pawls from the ratchets, then raising the pawls to the upper portion of the ratchet to provide a space between the clamping member and the work support, the articles having been inserted beneath the clamping plate, are advanced until their ends rest upon the platen 3. The clamping plate will then be forced downward into clamping engagement with the articles and will be locked in clamping position by the engagement of thepawls 12 with the teeth of the ratchets 15. All of the flexible articles to be marked will then be bent upwardly except the lowermost article which is permitted to I rest upon a platen.-

Any suitable means for printing the proper mark upon the article may be used, after which the marked article is depressed throughthe aperture 4; and the next lowermost article from the bottom of the superimposed series dropped upon the platen in marking position. This procedure may be continued until the entire pile of superimposed articles'is marked, after which the clamping plate may be removed by disengaging the pawls in the manner aforesaid and raising the clamping plate from en- In thus marking the articles any suitable printing mechanism maybe employed. Preferably, however, a printing deviceis provided which is movably secured to the frame in such manner that it can be swung into co-operative printing relation with the platen and removed from such relation to permit the application of ink to the type.

In the preferred construction illustrated in the accompanying drawing the printing mechanism comprises a printing head which is so mounted that it may be swung to and from printing position and in its swinging movement maintained with its printing face in substantial parallelism with the plane of the'work support. The preferred form of printing head shown in the accompanying drawing comprises a U-shaped body 19 having downwardly extending parallel arms 20 at-their lower ends which carry a suitable type-holding member. The printing head 19 is pivotally connected to a pair of parallel links 21, 22 which are pivotally connected at their opposite ends to the ends of parallel rock shafts 23, 24 respectively, which are journalled in bosses 25, 26 ex tending from a suitable standard 27 mounted upon the base 1. In order to ensure accuracy of movementof the head the rock shafts 23, 2 1 have rigidly secured to theni other parallel links 28, 29 which are connected together by a link 30.

The base 1 is provided, at the end opposite the work support, with an extension 31 and. a disk32 having an inking pador pads 33 is rotatably mounted upon the stud 34 upon an extension. The inking pad is, of course, so positioned as to be beneath the type face of the printing head when the latter is swung to one side of the standard, as illustrated in Fig. 1.

The printing head is provided with a handle 35. Desirable means are provided normally to support the printmg head in an intermediate osition out of en 'a ement with the platen and the inking pad. This preferably is accomplished by supporting the printing headupon a spring 36 which is connected at its lower end to a link 21 and at its upper end to the lateral extension 37 of a rod or post 38 which is detach-ably seated in the bosses which extend from the standard 27 and support the rock shafts 23 and 24.

In the operation of the machine the articles to be marked are placed upon the work support and clamped in the manner above described and all the articles are turned backwardly except the lowermost in such a manner as to leave the lowermost article lying upon the platen 3. The'print- CID ing head is then passed into engagement with f the inking pad, then raised and carried by the links over the vertical plane of the rock shafts and then depressed into printing engagement with the article upon the platen.

The printed article is then depressed through V the aperture 4 and the next article of the superimposed series permitted to drop upon the platen and the printing head pressed thereupon to mark it. This procedure is continued until all the articles of the pile. have I been marked. When it is found necessary to replenish the ink upon the type during this marking operation the head is swung again over the plane of the centers of the rock shafts and the printing face brought into engagement with the pad in the manner aforesaid. lVhen the printing is not being done the head 1s retained in an intermediate elevated position by the lifting spring 36 provided with a slot orv a 41 of the lower end of the printing head. The opposite side 42 of the plate is similarly bevelled. and is engaged by a complementary bevelled end of a dog 43 which is pivotally mounted upon the stud 44 extending from a lateral position 45 on the printing head. The stud 44 is provided with a handle 46 by means of which it may be pivotally moved and the handle is pressed outwardly. by a spring 47 so that the bevelled end normally engages the bevelled face of the type-holding member. The type-holding member is plurality of slots to receive the type.

The type are made of a width to fit within the slots and are provided with shouldered heads to rest upon the upper surface of the type-holding plate 39. The locking member, preferably in the form of,a plate 48, engages the upper ends of the type and holds them firmly in printing position and also acts as a backing member to receive the pressure which is imposed upon the type. The backing or looking plate 48 is pivotally mounted on a shaft 49 which is mounted in the arms 20 of the printing head and a suitable stop 50 extending from One of the arms 20 serves to limit the swinging movement of the plate 48 when it is in position to engage the type heads. A helical spring 51, which is secured at its lower end to the swinging locking plate 48 and at its upper end to an eye 5:2 upon the yoke of the head, serves to retain the locking plate 48 in engagement with the stop 50. The width of thelockin member 48 desirably is sufiicient to ena le its lowei edge to swing into substantial tangential relation to the upper ends of the type heads.

Deslrably an arm 53 extends laterally from the locking plate 48 and provides a convenient handle by which the locking plate 48 may be swung out of locking position against the action of the spring 51.

In order to introduce or to replace the type it is merely necessary to press downwardly upon the arm 53 thereby swinging the locking plate 48 out of locking position. The type can then be inserted into the slots in the type-holding member or if type are carried in the type-holding member they may be removed by merely raising them up and new type substituted. Thus a great sav ing in time which is required for changing the type is saved.

' if it is desired to remove the type holder and type it is merely necessary to press upon the arm 46 of the dog 43 sufficient to relieve the lower end thereof from engagement with the t pe-holding plate whereuponthe latter will rop out of the lower end of the head and can be readily replaced.

The arms 20 of the printing head may, if desired, be also provided with aligned apertured bosses 54 to receive the journals of a suitable type wheel which may carry several SQl'iGS of different insignia which are to be stamped upon different articles.

The present invention in'so far as it re lates to the mechanism for locking the type and type holder is a specific embodiment of the broader invention disclosedin my prior application Serial No. 723,974, filed July 3,

By reason of the present invention a simple and relatively inexpensive machine is" .1

provided for marking articles in which a pile of superimposed articles of like size can be readily marked and in which the type required for marking difi'erent articles can be rapidly assembled and replaced. As the printing head is normally supported out of. engagement with the platen or with the inking device the type extending downwardly is not likely to collect dust, and will not ac-v cumuiate an excessive amount of ink, as would be the case if thetype normally rested upon the inking pad. The machine as a whole comprises a convenient mechanism which is adapted to save considerable time printing claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:
