This inventionA relatesr generally to the manufacture of pencils, penholders and the like and has particular reference to printing or embossing advertising and similar matter l upon the pencils.

l sturdy mechanism which can be operated eficiently at high speed and with a minimum risk of ydamaging the work or interference with effective operation of the apparatus. y

Other objects and advantages will become apparent from the specification hereinafter given, that specification including a descrip- 'tion of a preferred embodiment of an apparatus shownin more or less detail in the drawings w'hich accompany and form a part of this specication.

In said drawings:

Fg. 1 represents a right side elevation of the mechanism with the nearest main side frame broken away and other parts in secgive a clear showing of some ofthe details. Y

Fig. 2 is a plan view taken substantially on the `line 2-2 of Fig. 1.

Fig. 3 is a front View of the mechanism with a part of the lower vframe cut away to expose tovview some of the parts in the lower portion of the machine.

Fig. 4 is a detail on an enlarged some of the parts shown in Fig. 3. f

Figs. 5, 6 and 7 show the work carrying table in dierent positions with respect to the printing-or embossing die and the way in which the work is brought intov cooperation with that die. A i

Fig. 8 is a top plan view on the line 8-8 of F ig. 3 of the work feeding mechanism and parts immediately associated therewith. Fig. 9 is a section alongthe line 9 9' of Fig. 4.

scale of The machine shown in theidrawin'gs isintended to set on a table or Vstand (not illustrated) so as to hold the mechanism at a` convenientworking level. The machine includes a base plate 15 and side plates 16 connected by cross members 17 to give a rigid support for the mechanism. Secured to the upper edges ofthe side plates 16 are bearing members 19in which are journaled a shaft 20.

At one end this shaft 20 has a sprocket 21 engaged by a chain 22 transmitting to the `sprocket 21 power from a motor or other source of power supply. Secured to the other end of the shaft 20 is a pinion`23 meshing with 'a large gear 24 fastened to a shaft 25. This shaft is j ournaled in members 26 and has attachedto it Vdriving sprockets and an interrupted gear referred to in detail later on. The relations of the pinion 23 and gear 24 are in the nature of aspeed reduction `connection to prevent a motor or other high speed transmission from operating the mechanism at an eX- 'cessive speed.` f

The interrupted gear above yreferred to is shown atw28in-the drawings and drives' a work-supporting table 29 in one direction. For this purpose the table is provided with a rack 30 on its'upper surface in the plane of movement of theinterrupted gear 28. The table 29 is supported on' fourro'llers 32, there being a pair at' each kside of the table. All four rollers loosely supported lon two rods 33 mounted in the yside plates of the framework. When all ofthe parts arev in their home .positions kthetwov `forward roll- -ers 32are engaged by cuts-or depressions 31 inthe lower surfaceof the table.

. Vhen the shaft 25 is rotated in the direction ,ofthe arrow, Fig. 1,L the interrupted` gear 28 willact against Itherack 30 to draw the table 29 krearward, against a spring 34, Fig. 2, attached to the lefty hand side frame .of the apparatus and flex the spring.l As the teeth off-the' interrupted orpartial gear 28 -pass out of engagement Iwith the rack 30 the spring 34 will throw the table 29 forward to its original position. Shortly after the rearward movement of the table hy the partial gear 28 and rack 30 is started the cuts 31` will `be carried past the forward rollers 32 andy cause the front portion Vof the table 29 tobe roll the pencil across the face of the die. The start of this rolling movement is indicated in Fig. 5. As the table reaches the end of its rearward stroke an inclined surface 83 is brought under the pencil so that it is relieved from pressure and allowed to drop into any convenient receptacle for the completed articles. This drop is facilitated as shown in F ig. 7 by the re-engagement of the cuts 31 in the table with the rollers 82.

While the apparatus shown and described is in itself novel and highly suitable for carrying out the process or method, that apparatus is capable of various modifications and changes and the process may obviously be practiced by other means. It is not, therefore, the desire to be limited to the disclosure herein made of either the apparatus or the process except as such limitations may appear in the claims which follow.

What is claimed is:

l. In an apparatus of the character described, the combination of a support for the work, a heated die, a reciprocating member for feeding pencils and the like to the work support adjacent the die, and means comprising a cam rotating on an axis parallel to the line of movement of the reciprocating member for effecting movements of said member.

2. In an apparatus of the character described, the combination of a support for the work, a heated die, a reciprocating member for feeding pencils and the like to the work support .adjacent the die, and means comprising a cam rotating on an axis paralled to the line of movement of the reciprocating member for effecting and controlling the reciprocations of said member.

3. In an apparatus of the character described, the combination of a support for the work, a type carrying die, .a reciprocating member for feeding the pencils to the work support, devices for effecting a relative movement of the work support and' die in such a manner as to roll the pencil between the support and the die, and means comprising a cam rotating on an axis paralled to the line of movement of the reciprocating member for effecting the movements of said member.

4. In an apparatus of the character described, the combination of a support for the work, a heated die, means for feedino pencils to the work support, devices for effecting a relative movement of the die and work support to roll the pencils between the die and support, a. carrier strip for a marking material crossing the face of the die, and devices for automatically feeding said carrier strip a step between each pencil rolling operation.

5. In an apparatus of the character described, the combination of a heated die, means for rolling pencils across the face of the die, a foil carrier strip across the face of the die, and devices for automatically feeding saidgstrip a step relative to the die between each pencil rolling operation.

6. In an apparatus of the character described, a heated die anda work support relatively movable to roll pencils between them, a hopper for pencils, devices for moving the pencils one at a time endwise to deposit them on the work support, a foil carrier strip across the face of the die, and devices for automatically feeding said strip a step between each relative movement of die and work support.

7 In an apparatus of the character described, a heated die and work support relatively movable to roll pencils between them, a hopper for holding a supply of pencils, devices for moving the pencils one at a time endwise to deposit them on the work support, a foil carrier strip across the face of the die, devices for automatically feeding said strip a step between each relative movement of the die 4and work support, and means for regulating the length of said feeding movements.

In testimony whereof I hereto aliix my signature.

WALTHER FRIEDLAENDER.
