nrroewiyf Patented Aug. 30, 1932 ANDREW .1. nor'rrs, or nn'rnomnronmaiv PLACING TOOL non auromonrrn moa'onvanvii: sates Application filed April 28,

This invention relates to tools, and particularly to a special tool which is small and compact, and designed for the purpose of placing the horse-shoe like member into the groove provided for the same, which is 105 cated near the lowermost end of the valve stem of an automobile motor, while the valve spring is compressed by means of a valve lifter. V I

The tool embodies a pair of concaved jaws adapted to receive and clamp the valve shoe, with the open end of the shoe exposed; the tool being of adequate length to enable the operator thereof to place the shoe within the groove upon the valve stem without the necessity of inserting the fingers in the congested location of the said groove; the shoe is then instantly released by merely sliding a top plate upon the tool, a slight distance rearwardly. The invention will be found to be equally advantageous in removing the shoe from the valve stem, which is as readily accomplished as the inserting operation.

The outstanding advantage of the invention is the fact that due to thesmall proportions of the valve shoe, and it being very diflicult to hold the same with the fingers in the inserting or removing of it from the stem, it is easily dropped into a more difiicult place in which to locate and to remove with the fingers; the invention positively eliminates loss or misplacing of the shoe, thus greatly facilitating this work, and thereby saving much time andtrouble.

One of the advantages of the invention, and one of no less importancethan those heretofore mentioned, is that owing to the extreme simple manner of construction embodied, it may be manufactured at a very low cost, and accordingly the low selling price, and in consideration of the utility of same, a very large demand would thus be created.

The invention possesses further advantages, all of which will be clearly revealed during the course of the detailed description to follow, illustrated in the accompanying drawing, and more particularly pointed out in the appended claim.

WVith reference to the drawing:

valve shoe into 1980. seria No. 447,989-

Figure 1 is a reduced sectional view of a. portion of a modern automobile motor, and showing the tool in theact of placing the position; the valve spring being in an elevated position, with valve lifter omitted. I

Figure 2'is a top plan view of the complete-tool, with'valveshoe within its jaws.

Figure 3 is a side elevation of the invention, showing same with the jaws thereof in w an opened position.

-' Figure 4 is a'side elevation of the inven tion with jaws closed, and clamping the valve shoe in a position ready to insert the same within'the groove of the valvestem; the 5 dotted linesin this'view indicate the said stem and groove.

' Figure 5 is-a top plan view of aportion of the principal member of the device, clearly showing the elongated slot therein.

a Figure 6-isa top plan view ofthe sliding member of the device. a 1 Figure 7 is a longitudinal section showing the sliding member in relation to the elongatedslots of the principal member.

Figure 8 is a top plan -view of the lower plate member of the device; A

Figure 9 is a section showing the formation of thej'aws of the device.

The invention consists of a principal memso her desi nated by the numeral 1, one end thereof ormed as at 2, and the opposite end adapted to open, as in Figure 3, and having a pair of opposed integral jaws 4, and the said jaws formed as clearly seen in-Figure 9.

Sliding member 5 is provided, and one end thereof formed as at 6, and is secured to plate 7 by means of rivets 8, and with reference to Figure 7 it will be noted that said rivets are adapted to slide within elongated slots 9 of the member 1 as shown. Holes 10 in members 5 and 7 are for passage of rivets 8; Cotter pin 11 forms a stop for the opening of the jaws 4, and hole 12 in member 1 accommodates said pin.

From the foregoing, it is now understood that the invention is normally as indicated in Figure 3, and by placing one finger with in portion 2 of member 1, and a finger of the other hand placed within portion 6 of memher 5, and by placing shoe A between jaws 4, and b sliding member 5 to the position indicate in Figure 4, the said shoe is positively clamped and ready to be placed into B'position. When the shoe is in its proper lace member 5 slides to normal position, as 1n Figure 3, by pulling portion 6 thereof, instantly releasing the shoe, the tool ,may then be quickly removed from the motor. 10 While I have herein illustrated a single embodiment of my invention, the same is nevertheless susceptible to certain minor changes in the details of construction, or of a design, during any probable further development of the same for the market; but in any event, a departure from the general principle disclosed would of course be consistentl avoided. I 1

aving thus described my invention, what .20 I claim as new is: r

In a device of the character described, a flat elongated principal member for the device, the said member composed of a single piece, one end thereofformed into a loop and the oppositely disposed endof this member forming a pair of jaws, and'the said jaws oppositely disposed, this member also forming a handle portion with double thickness of metal for this portion; a plate with a finger hold formed upon theouter end there0f,'and the said plate upon the topmost surface of the said handle portion, also an additional plate immediately below the underneath surface of the said handle portion and adjacent thereto, the first-namedplate and the last-namedplate being secured byrivets in a manner so as to freely slide upon the said handle portion, an elongated slot within the said principal member permitting the riv- 40 ets of the said plates to pass through the same in the normal operation of the device, also means whereby the aforesaid jaws are limited relative to their opening movement.

In testimony whereof I hereunto aflix my signature. 7 I V v ANDREW J, DOPTTS.
