Abstract

A jogger device for jogging signatures or sheets during the formation of stacks in bookbinding machines, such as loaders, including an oscillating disk which is driven of reciprocating motion by a source of reciprocating motion and transmits said reciprocating motion to the supports of two side jogging vanes. Thus, the jogging device can have reduced transversal dimensions. The central vane of the device is carried by the element imparting the reciprocating motion to the oscillating disk.

Dependent claims

A jogger device for jogging signatures or sheets during the formation of stacks in bookbinding machines, said jogger device comprising:

(A) a source of rotary motion,
(B) a supporting structure,
(C) a central jogging vane,
(D) two side jogging vanes,
(E) displaceable elements supporting said central and side vanes from said supporting structure for jogging movement relative to said structure,
(F) means for converting the rotary motion of said source of rotary motion to reciprocating motion,
(G) one of said displaceable elements constituting an elongated straight element,
(H) means mounting said straight element for axial reciprocation,
(I) means securing the central vane to the straight element, and
(J) means adjustably connecting the side vanes to the displaceable elements for the same, characteristized in that:
(K) said supporting structure constitutes two side members connected by two elongated mutually spaced transverse members,
(L) said means for mounting said axially reciprocating straight element being supported by said two mutually spaced transverse members,
(M) a bracket mounted on said axially reciprocating straight element,
(N) a pin carried by said bracket,
(O) an oscillating element rotatably mounted on said support means for said reciprocating straight element,
(P) a pair of pins carried by said oscillating element at diametrically opposed points with respect to the axis of rotation of the oscillating element,
(Q) a radial slot in the oscillating element in which the bracket pin rides,
(R) two transverse rods mutually spaced apart and located between said side members,
(S) means mounting said rods for independent axial reciprocation,
(T) said rods being shorter than the distance between the side members,
(U) each of said rods having means thereon for engaging a different one of the pins supported by the oscillating element, and
(V) said displaceable elements which support the side vanes being adjustably connected to different ones of the rods,
(W) whereby rotation of the source of rotary motion jogs the central vane in a direction transverse to the axially reciprocating members and jogs the side vanes in a direction transverse to the jogging direction of the central vane.
