1 UNITED STATES) JACOB scmcx, or SOUND "amen, CONNECTICVITT, ASSIGNOR T MAGAZINE aErEATme RAZOR COMPANY, CORPORATION N JERSEY 301mm FOB usnmeamnmemacnrnns Application filed April 6 ,'1 927. set "No. 1 1 ,'29o.

This invention relates to an improved hold er for use in blade grinding and honing machines and is of the type used in the machine described in the application in which I am a joint inventor. with'Dorlias Nadeau, which application was filed May 19, 1926, Serial Number 110,045.

The device is a holder which retains and passes a blade along the grinding or honing discs and travels in a rigid track since the grinding is with precision. and the holder is astable rigid one. The invention embodies a holder of a construction that allows a quick insertion and removal of blades into and from the holder, which is of advantage in quick production machinery which includes a filling mechanism for inserting blades in the holder and a stacking machine which removes the blades endwise from the holders and places them in stacks for use in safety razors.

The invention can be used in other connecvtions but is primarily constructed for the holding of narrow blades such as are used in my magazine razor patented May 18,1926,

The invention is illustrated in the accompanying drawing in which Figure 1 is a side view of a holder for receiving: five blades. Figure 2 is an enlarged section of. the holder closed and Figure 3 is a similar View showing the holder open to receive a blade. Figure 4 is a top view of a multiple: holder showing a set of releasing tools for opening the hold- 5 er. Figure 5 is a sectional perspective of the holder and Figure '6 of modified form. 7

The holdercan be made in single units each holding a blade but inipractice it is usual to 0 have each holder receive a number of blades. The invention, can be made in single units but I show in the drawing a holder for five blades the holder having abase 10 on which is a rigid wall 11. Theparts of the holder Elare usually made of steel and are hardened so as to be durable especially in view of their being slid lengthwise in a track of suitable construction. The holder "has a'plate secured to the wall 11 and I show a plate 12 51 securedby a screw 13 and the plate and wall is a section of aholder ledge, said led cooperate to hold 'a blade 14 betweenthem at their ends, the blade resting on a'shoulder on oneof the elements such as the shoulder 15'on thefwall 11'. The plate 12 is cut away at desired points/such as the hollow'pa-rt 16- to give enough resiliency to the plateto enable it to spring a little torelease-or receive the blade 14.

The plate 12 is designed to be sprung outvwardly to load and unload it, usually in a machine for this purpose and I have illustrated a prong or prongs 17 which is adapted to pass through the hole or holes 18 in the wall 11 so that the plate can be sprung outward as shown in Figure 3.

The outer walls of the wall 11 and plate 12 are tapered towardthe topto allow the grinding or honing from the holder, by again pressing a set of prongs 17 against the plate 12', this time in an unloading machine.

discs 19 to bearranged 1 at the proper angle to'treat the edge of the blade 14.

in the quantity In Figure '6 I show a modifiedform of I plate, which plate 20 is pivoted as at 21 to the wall 11 and the spring 22 holds it in clamping position. The prong 17 in this case engages the plate 20 below the pivot to open the holder toinsert or remove a blade 14.

,I claim: i

1. A blade holder for sharpening machines 5 comprising an elongated rigid back plate, clamping jaws rigidly fixed blades, one of said ge being of sufficient width to maintain the aws in spaced. relation, said space being less than the normal thickness,

to said back plate 1 and of sufficient length to hold a plurality of jaws having an inner of the blades held, thus enabling the jaws to properly grip and hold the blades; one of sald clamping jaws being' rigid and the other resilient, said rigid jaw extending uninterruptedly the whole length of the holder, the said resilient jaw being divided to afford a plurality of clamping lingers adapted to engage the blades individually, thus adapting the holder to grip blades of slightly vary-' ing thickness properly.

2. A blade holder for sharpening machines comprising an elongated rigid back plate, and clamping jaws rigidly fixed to said back plate and of suflicient length orex- 1 tent to hold a plurality of blades, one of said jaws having a ledge of less width than the thickness of the blades to be sharpened, so that the normal space between the outer grippin edges of said jaws will be less than the thic ness of the blades to be inserted in the holder, thus enabling the jaws to properly grip and hold the blades, said back plate being provided with a groove or channel in which the backs of the clamping aws fit.

In testimony whereof I aflix m signature.

JACOB CHICK.
