1 MECHANICAL MOVEMENT.

To all whom iii may concern:

vBe it known that 1, JOHN E. HIREs, a

citizen of the. United States, and a resident of Ardmore, Montgomery county, Pennsyl- Vania, have invented Improvements in Me-- chanical Movements, of which the following g which rotative movement maybe applied to is a specification. V v r My invention relates to means for transforming a 'reciprocative movement of a driven/member into rotative movement,

a driving shaft or spindle. I The structure forming :the sub ect of my inventionhas been employed for operating counting mechanism, and specifically in con nection with anelectrically operated device for counting cans, boxes, and variousother articles while the same are moving past a given point. One feature of such construc tion is the provision of an electrical device which will accurately count the articles-as they pass no'matter how fast they travel,

and a further feature is the arrangement of thecounting mechanism and its operating means so that such structure can be placed at some distance from the-point at which the cans, boxes, orother articles are moving. The countingdevice is. part cularly well adaptedfor use in thecountmg of cans,

bottles, boxes, or other objects in'a factory J; or-warehousewherein the movement of such articles mayqeffect the closure of anjelec-j I tricalcircuit wherebythe mechanical device forming'sthe subject of my invention may operate such counting V mechan smv located 1n an office or other central point. I It will be understood, of c,ourse,.,that my improved 'mechanical movement may be employed and operated in connection wlth various moving parts of machinery ofdifferent kinds, since its. use is not limited to operation by an electri'calmeans. I u

These and other features of my invention are more fully described hereinafter, reference being bad to the I accompanying draw- .1 ings, n whlchz Figure "1, is a planviewj of the counting mechanism and one-form of actuating means therefor forming the subject of my invention, the same being shown as arranged for electrical; operation; Fig. 2, is a sectional elevation of the operatingmechanism on the line a' a, Fig. 1;..Fig. 3,is an enlarged sectional View of the means employed to transform longitudinal movement a into rota: tive movement for the operation, ;of the Specification of Letters latent.

counter; Figs. 4 and 5, are views illustrating dlagrammatically the manner of operating the counter; Figs. 6, 7 and 8, are views illus-v trating various forms of mechanical devices for operating the counting mechanism; Fig. 9,;isa view of a slightly modified construction; Fig. 10, is a view showing my improvement in connection with a solenoid; Fig. 11, is aperspective view illustrating a trough or runway for objects arranged to pass contact points for closing an electric circuit to operate the counting device, and Figs. l2, l3 and 1%, are views illustrating in detail the character of contact points and their operating means which I may employ in the counting of cylindrical and rectangular bodies. v

The counting device proper may be any of the usual structures now upon the market, and in practice I have used a Veeder counter which is illustrated at 1. The shaft of this counter is eXtendedat 2, and mounted upon this shaft is a ratchet or pinion 3 having sets of teeth 4: and 5 at opposite ends of the same, of the shape clearly shown in the drawings. Inclosing this pinion is a slidable, non-rotataive sleeve 6 having sets of internal teeth 7 and 8 at opposite ends of the same adapted to engage alternately the sets of teeth {l and 5 at theopposite ends of the pinion 3. One set of internal teeth may be formed on a screw threaded part adapted to threads on the sleeve 6, and having a fixed relation to the sleeve while the other set is carried by an adjustable collar 9, which may be secured to the sleeve by a set screw 10. The teeth are preferably shaped as shown in Figs. 1 and 3, being beveled on one side so that when the two beveled surfaces comein contact the pinion against longitudinal movement, whereby the pinion may be rotated step by step and thereby effect unlt operation of the counting shaft and the counting wheels carriedthereby, and various meansmay be employed to impart such movement thereto.

In Figs. 1, 2, 3, land 8, I have shown an electrically operated structure. I In this arrangement l employ a pair of magnets ll whichv may be energized by the closing. of an" electriccircuit inwhich the necessary; (1011f tacts are actuated by a moving can, box or other body passing along a chute or runway 12, and these magnets attract an armature bar 13 attached to the sleeve (5. A spring 1% is located between the armature and the casing of the counter in the present instance, and acts to return the armature after attraction. The attraction effects longitudinal movement of the sleeve with respect to the ratchet or pinion 3, and by reason of the engagement of the teeth of the sleeve and pinion at the termination of the reciprocz tive movements of the sleeve, the counting shaft will be rotatively moved, and the arrangement is such that such shaft is moved one-twentieth of a revolution by the movement of the sleeve in one direction under the magnetic influence, and one-twentieth of a revolution by the movement of the sleeve in the opposite direction by the spring let, the total extent of such reciprocative movements effecting the movement of the counting shaft one-tenth of a full revolution, and therefore racking forward one of the disks of the counter one unit. The counter is provided with the usual cooperating mechanism between the disks so that movement of the first or unit disk will effect movement of the other disks at the proper time to count ens, hundreds &c.

In Figs. 1, 2, 3 and at, 1 have shown the counting device as disposed between the magnets, while in Fig. 9, I have shown the counting device arranged outside and be yond the same. in Fig. 10 l have shown the device operated by a solenoid magnet 11 the sleeve 6 forming part of the sliding core and the spring 1 ibeingso located as to project the sleeve when the contact is oronen.

Any means may be employed to impart longitudinal movement to the sleeve, and therefore effect step-by-step rotation of the pinion or ratchet member 3; hence it is applicable to any form of moving machinery, in which it is desired to count the number of operations, or the number of parts delivcred, or any other operation of which a record may be desired to be kept.

The sleeve may be directly connected to a moving part of such machinery, as in Fig. 6, where it is shown attached to the pitman 15 of an eccentric, or cams may be employed to operate the sleeve, as in Figs. 7 and S; the cam 16 shown in Fig. 7, effecting movement of the sleeve in one direction and a spring moving the sleeve in the opposite direction. A lever or arm may be arranged to operate the sleeve if desired. In most instances, a spring will be employed to restore the sleeve to its normal position, although if a cam is employed it may have such an operative connection with the sleeve as to move the latter in both directions upon a full revolution of the cam, as in the structure shown in Fig. 8, in which a cam 17 is shown as grooved at 18 to engage a pin 19 011 the sleeve.

In counting cans and similar articles which may revolve or roll in passing down a chute or runway, I may employ a contact closing device, such as that shown in Figs. 12 and 13 which includes a rotatable shaft or spindle 20 having wings or arms 21 which lie in the path of said cans or other objects; the engagement of said cans with the wings moving the latter one-fourth of a revolution for each can or other ob ect passing said wings, and the shaft 20 upon which said wings are mounted being provided with a cam or other device whereby a suitable contact arm may be actuated. In the present instance, I may employ a fixed contact 22 connected to one terminal, and a movable contact arm 23 connected. to the other terminal, which movable contact is actuated by a cam 20 on the shaft 20. I preferably employ platinum contact points and 26, although any suitable form of contacts may be used.

When counting boxes or similar structures which may slide along a runway, or be carried by a conveyer or elevator, I employ a circuit closing trip 27 Fig. 14 which ice in the path of the moving boxes. This trip is arranged to swing between an inactive and active position, and is mounted on a spindle or shaft 28 carrying a cam or arm 29 to raise a movable contact arm 23 in engagement with the fixed contact point 52-2 whereby the circuit is closed each time a box passes such trip; the closing of such circuit actuating the arn'iature to effect movement of one unit of the counting mechanism.

While I have described the ratchet or pinion 3 as provided with a complete set of teeth at each end for engagement with C0111? plete sets of internal teeth disposed within the sleeve 6, it will be understood that a single tooth or pair of teeth at each end of the pinion may be employed in connection with full sets of internal teeth carried by the sleeve, or the sleeve may have a single tooth or pair of teeth at each end for coaction with full sets of teeth on the ends of the ratchet or pinion 3, without departing from my invention.

While I have shown and described a structure in which a non-rotative toothed sleeve is moved relatively to a ratchet or pinion having teeth at its ends and carried by the rotatable counting shaft, it will be undcrstood that the sleeve may be connected to the shaft of the counting mechanism and be rotated by engagement with a non-rotative ratchet or pinion which is longitudinally reciprocated with respect to said sleeve,
