UNITED STATES PATENT OFFICE LEE C. CASE, OF SAGINAW, MICHIGAN, .ASSIGNOR TO WILCOX PRODUCTS CORPORATION, OF SAGINAW, MICHIGAN, A CORPORATION OF MICHIGAN SHIPPING IACKAGE FOB A TAPPETS Applicationled December 12, 1927. Serial No. 239,333.

This invention relatesto packaging the tappets of internal combustion motors and similar articles;

The invention has for its object to provide a packing means constructed in such manner that the ardened and polished stems of the tappets can not touch each other and cause microscopic nicks and defects in their pol-n ished surfaces. during shipment. The polo ished heads are protected and the tappets are held against endwise movement in the ship# ping crate.

A further object is to provide simple means lfor packing the tappets in very small v space and for conveniently .handling them in small quantities in a motor assembling plant without danger of injuringthem.

.With the foregoing and certain other objects in view, which will appear later in the specifications, my invention comprises the devices described and claimed and the equivalents thereof.

In the drawings Fig. l is a plan view ofa perforated sheet.

Figf 2 is a part sectional view of a perforated sheet with some of the tappets in place together with a facing panel constituting a tray unit.

Fig. 3 is a similar view, showing a tray unit of tappets inverted. i

Fig. 4l is a part diagrammatic sectional view showing a pair of inter-engaged tray units, constituting a layer, and indicating the manner of piling several layers to form a tier. Fig. 5 is a longitudinal section throuufh a packing case, showing two tiers of threeDla-yers each packed therein.

As shown in Figs. 2 and 3, the prime element of the package assembly is a tray unit,

4c the cylindrical body 1 ofeach tappet project- The individual tappets are thus held so they' can not move either sidewise or lengthwise. Two such tray units laden with tappets are placed together, as illustrated at the bottom of Fig. 4, so the polished cylindrical bodies of their respectlve tappets interdigitate without touching, as indicated by dotted circles in Fig. l.

Whenl placed together in this manner the ends of the .tappets of either tray press against the sheet 3 of the opposite tray and are securely held in place by frictional engagement. When two trays of tappets are thus placed together the form what I term a.- layer. A number o such layers piled together, as indicated diagrammatically in Fig. 4, constitute a tier for lling a compartment 6 of a crate or shipping case, Fig. 5.

In practice a perforated sheet 3 is first loaded with tappets by pushing the tappet stems 1 downward through the holes 2, as in Fig. 2. A facing panel-5 is then laid on top, covering the tappet faces, and the tray unit so formed is inverted, Fig. 3, and lowered into the crate. Similarly, a second tray, the holes of which are staggered with respect to the holes of the first tray is loaded with tappets and covered with a facing panel and is then lowered into the crate, forming together with the first tray a layer. Then a second layer is made and put into the crate and so on until a complete tier is built up, filling a compartment 6 of the packing case.

A cover member 7 of about the same size as the trays 3 and panels 5, is then put on top of the tier and forced down and fastened to compact all the tappets and their trays. The yielding material of the perforated sheets 3 and panels 5 firmly holds every individual tappet end in place. The tappets then can not be jolted out oftheir proper positions.

I have mentioned that a so-called layer is made up of two tray units placed togeher so their. individual tappets do not touch, and have stated that the holes of their two perforated sheets are staggered with respect to each other. A single sheet pattern is made to accomplish this pur ose by arranging its holes as indicated in ig. 1, where 8 and 9 are adjacent margins ofa tray 3, being wider than the two remaining margins by an amount equal to half the regular pitch 10 of the holes.

Obviously, when a corner as A of a perforated sheet 3 turned around to the position A the holes represented by the two positions will be located as shown by the full circles and dotted circles in Fig. 1, so it is only necessary in packing tappets according to this method to turn alternate sheets 3 around in the manner above explained.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. The means for packing articles that consist of a stem wit a laterally projecting flange at an end thereof, said means comprising a'perforated sheet to receive tappet stems and a facing panel, the heads of the tappets received and releasably held between the panel and sheet, for the purpose set forth.

' 2. The means for packing' tappets and like articles having stems and flanged heads, said means comprising a sheet perforated to receive tappet stems, the centers of the perforations spaced apart by a distance slightly greater than the diameter of a tappet head, a loose facing panel, the heads of the articles received between said panel and sheet, a pair of said sheets and their panels so laden with tap ets placed together with their stems inter 'gitating without touching, and crate elements for holding all of said facing panels and sheets together, for the purposes set forth.

3. The `means for packing tappets and like iange-headed articles comprising a perforated sheet of yielding material to receive tappet stems and to provlde support for their heads, a facing panel removably overlying the heads of the tappets on said sheet, a. pair of said sheets and their facing panels so laden with tappets placed together with their stems interdigitating without touching and comprising a layer, a plurality of said layers superposed to form a tier, a crate compartment receiving said tier and having a cover member downwardly movable therein and means for pressing and holding said cover member upon said tier, for th'e purposes set forth.

In testimony whereof, I atlx my signature.

LEE C. CASE.
