in opposite directions. As the books come from an assembling apparatus, they all face in the same direction, and it is the purpose of this invention to receive them from such apparatus, reverse the alternate books and position the. consecutive books in a stack.

Different forms of apparatus have been heretofore suggested and employed for this purpose, but the present invention accomplishes the stacking operation .in a more expeditious and positive manner and through the employment of more simple mechanism than'heretofore provided for'this purpose.

The primary object of the inventionris to provide for the purpose stated an 'apparatus of unusual simplicity and one susceptible of operating at the highest speeds with uniformly good results. i

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate one practical embodiment of the invention, but theconstruction therein shown is to be understood as illustrative, only, and .not as defining the limits of the invention.

Figures 1 to 4 inclusive are elevations, partly in section showing apparatus embodying this invention in different stages of its operation.

constitutethe discharge table of an'assembling machine, so that after the books have been assembled, they are fed in completed condition along the table 1 to the stacker unit. For graphic illustration, three consecutive books designated A, Band C are shown in Figures 1 to 4. Beyond the discharge end of thetable I is a chute Qan'd into the end of this chute the books are adapted to befed by the stacker and they are adapted to move'in stacked condition downwardly through this chute to either packaging mechanism or into convenient position wherein an operator may remove'the books in stacked condition and manually place them in boxes or cartons. i

Positionedrin upstanding relation at the back edge of the table and at its discharge end'is a standard 3 which standard carries a bearing 4; In this bearing'a tubular spindle 5 ismounted for vertical reciprocation and to the lower end of this spindle is secured a stacker head 6. This stacker head is provided with a pair of spring holders 7, the lower ends of which are shaped as shown at 8 to receive between them a match book. The stacker head'6 is substantiallyv cylindrical, but is provided with oppositely positioned flat faces 9 with which a pair of brackets '10 are adapted to cooperate. These brackets are pivoted to the bearing 4; a's shown and' are impelled by springs 11 with the head 6 at all times. Additional springslQ, shown in Figure 6, may be employed, so as to insure a firm gripping engagement of the brackets withthe flat faces '9. These flat faces are so disposedthat when the brackets are in engagement therewith theseats 8 of the spring'holder will'be alined with the path of travel of the books along into engagement the table 1 so that as the books are fed along the table,-they will be forced into engagement with theseats of the spring holder, for reasons hereinafter more fully explained;

The upper end of the tubular spindle 5 is provided with a cam follower plate 1 1 having a dependinghub, and spring 16 is interposed between [this hub and the bearing 4'to normally impel the stacker head in an upward direction. To allow of a fairly long spring, the bearing may be made hollow as shown in Figure 1.

Carried at the upper end of the standard 3 is a shaft 17 to the forward end of which shaft is secured a cam 18, and this cam is adapted for cooperation with the cam follower 14 to oppose the action of the spring- 16 andthrough the operations of the cam, the tubular spindle 5 is vertically reciprocated. The cam is also provided with a segmental rack or mutilated gear 19 and this mutilated gear is adapted for periodical cooperation with a pinion 20 rigid with the cam follower 14, so that as the spindle is raised and lowered, it is periodically rotated. The gearing connectionsare such that for each rotary impulse the stacker head will be turned through 180 degrees. The cam 18 also carries a wrist pin 21, and this wrist pin is secured by means of a connecting rod 22 to the upper end of a plunger 23 having an enlarged pressure foot 24.

The shaft 17 is provided at its rear end with a sprocket 25 driven by a chain 26 from a sprocket 27 having a gearing connection 28 with a main power shaft 29.

' At the upper end of the chute2'are a pair of trap doors in the form of flaps 31. These are pivoted at 32 and are provided with stops 33. Springs 34 coact with the pivots of these trap doors, so as to normally hold the doors in the closed position shown in Figure 5. It will be noted, however, that if a match book is pressed down when it is lying either directly upon the trap doors or is carried by the holder.

7, the doors will be caused toopen in a downward direction to let the match book or the holder pass by, but as soon as the holder is elevatedagain, the doors will close so as to keep the matches previously introduced into the chute from lifting up and getting in the way of the feed of subsequent matches into position above thechute. These trap doors or flaps, therefore serve the function of holding the book matches in the chute after they have beenplaced therein. The operation of the apparatus will now be described.

Starting with the parts in the position shown in Figure 1, it will be noted that the plunger foot 24 is in a position wherein it has forced previous match books downwardly into the chute 2. The holder 7 is in position to receive book A and is at rest. As the disk continues to rotate in the direction of the arrow from the position of Figure 1 to the position of Fig. 2, the plunger foot 24 is elevated and as soon as it has moved above the plane of the table 1 suitable feed mechanism 106 associated with the table advances the match books to feed the book A'into the holder so that by the time the parts come into the position of Figure 2, the book A has been positioned in the holder as indicated in this figure. The cam periphery of the disk 18 is such as to maintain the holder stationary during this period, but immediately thereafter the follower 14 passes on to a lower phase of the cam with the result that the holder is elevated and immediately thereafter the rack 19 engages with and drives the pinion 20 to rotate the holder as indicated in Fig. 3. This rotation continues until the holder is rotated through 180 degrees whereby the'match book is reversed. During this period, however, the next match book B is fed directly on to the trap doors at the top of the chute 2 as shown in Fig. 3. 7 After the holder has been rotated through 180 degrees, the cam surface acts upon the cam follower 14 to again force the holder downwardly until it comes to approximately the position of Figure 4 whereupon theplunger23 which is during this period being depressed the book A from the holder and deposits it in the chute 2; In so doing the trap doors are forced open to admit the match book into the chute. The holder continues to lower, while the connecting rod 22 passes over lower dead the book C being next fed'intothe holder.

In practice, the apparatus is found to operate very smoothly without appreciable vibration andmay'be operated at high speeds unfailingly to produce the results stated.

The foregoing detailed description and drawings illustrate the invention in its preferredpractical form, but the inventionis to be understood as commensuratewith the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:
