Sweden Application December 17, 1935, Serial No. 54,916 In Germany February 12, 1934 Claims.
The present invention relates to a method of manufacturing exchangeable calks for horseshoes comp-rising Wedges and holders therefor, where the horse-shoes are provided with substan- 5 tially rectangular holes, in each of which two holding members are applied, between which a wedge member is to be driven in.
The invention has for its object to facilitate by simple working operations a rational, cheap and simple manufacturing of the above mentioned members While maintaining a great accuracy.
The invention consists essentially in this that the wedges and the holding members are punched out from a double profile-material, in such a manner that the wedges obtain at least two flexible flaps and the holding members corresponding recesses and projections for bending the said flaps at the driving in of the wedge between the holding members,
The manufacturing of the wedges from a double profile-material may preferably be performed in such a manner that there are punched out, in the web of the double profile-material, holes or apertures having a substantially rectangular shape with the length direction substantially parallel with the transverse direction of the profile-material and also apertures having substantially an H-shape with the staffs lying substantially parallel to the said transverse direction and at a distance from the rectangular apertures and then cuttings or shearings are made longitudinally and transversely with respect to the profile-material, so that wedges are formed, each comprising a tread portion, a wedge-shaped portion to be driven in into the horse-shoe, and flexible fiaps projecting from said latter portion.
The invention is illustrated in the annexed drawing. Fig. 1 is a crosssectional view of the profile-material for wedge members to be used in summer time, and Fig. 2 a plan view thereof. Fig. 3 is an end View of a finished wedge member. Figs. 4, 5 and 6 are similar views of a profile-material and a wedge member to be used in winter 45 time. Fig. '7 is a cross-sectional view of the profile-material for the holding members, and Fig. 8 is a plan view thereof. Fig. 9 is a side view and Fig. 10 an end view of a finished holding member. Fig. 11 shows a portion of a horse-shoe partly in section having holding members and a wedge member applied.
The punching iscperformed in an ordinary stamping machine by means of suitable punches having a figuration according to the above mentioned apertures or holes, whereby the succession of the separate punching operations may vary.
A first step may consist in punching a transverse hole 3 in the web 4 of the profile-material i 'of the shape shownin Fig. 2. Then the punching of the H-shaped slot 5 in the web is performed, and simultaneously depressions 6 may be formed in proximity to the swelled tread portion 1, so that there is formed a projection 8 at the opposite side of the web, said projection serving as a guide at the driving in of the wedge member 2 between the holding members, as will be more clearly described below. Then a cutting or shearing is performed along the longitudinal central line Z and also along the transverse central lines Z1 and Z2 of two adjacent holes 3, two wedge members having flexible flaps 9, a tread portion 1 and the projection 8 being thus produced at a time.
Obviously the succession of the punching steps may be another than that one above described. Thus, the punching 5 and the depression 6 may be performed in a first step and then the punching 3 followed by the shearing operation.
The manufacture of wedge members to be used in winter time according to Figs. 4 to 6 is performed by punching, depressing and shearing in the same manner as described above, however with the difference that wedge or triangularly shaped slots l5 are punched out at the edges of the profile-iron I for instance simultaneously with the punching of the apertures 5. The difference as to the finished wedge member 2 consists, besides, in this only that the tread portion I is here wedge-shaped in order to be more suitable for use in winter time.
As apparent from Fig. 4, each half of the pro file-iron shows in cross-section the shape of two wedges having the bases turned towards each other, the symmetry lines of said wedges forming an angle with each other, as shown by the dashed and dotted lines. 7 the horse-shoe in a suitable manner tread injuries may by such means be avoided and, besides, the wedge can be applied to suit different walks of horses.
The wedge-shaped tread portion may be provided at the one side or, as shown, at both sides with swelled portions 1 8, which indicate, when the wedge has been worn out to such an. extent that an exchange is to be made. The swelled portions also facilitate the tempering of the wedges, inasmuch as they may form a stop at the immersing of the wedges into the tempering liquid and, besides, due to the accumulation of material separate the tread portion 1 adapted to By inserting the wedges in be tempered to a higher degree from the relatively soft portion adapted to be driven in between the holding members and the flaps of which have to be flexible.
The manufacturing of the holding members ll according to Figs. '7 to 10 may for instance be performed in the following manner,
By a pressing operation projections [3 are at first formed at the longitudinal edges of the profile-material l0, and then recesses M are stamped out adjacent to the said projections and simultaneously depressions l2 may be made at the central part of the material, said depressions being adapted to serve as a guiding slot for the projection 8 of the wedge member 2 at the driving in thereof between the holding members I I. Finally cutting or shearing is performed along the dashed and dotted lines, Fig. 8, and two holding members will be produced at a time. By such a method the profile-material will be very economically utilized, since the central rib I! only will remain as wastrel.
At the applying of two holding members against each other the projection l3 of the one member will correspond to the recess Id of the other and vice versa, so that after the inserting of the holding members into the horse-shoe and at the driving in of the wedge member, Fig. 11, the projections l3 will bend the flaps 9 of the wedge member in opposite directions, whereby the flaps enter the recesses 14.
As apparent from Figs. 1, 4 and 7 the web of the profile-material has in cross-section the shape of two truncated wedge-shaped parts directing the apices towards each other, which parts are joined by a rectangular or square part l6, whereby two equilocated sides of the wedge shaped parts may lie in the same plane, so that the punches can obtain a plane working surface.
