45 -Fig. 3 is a similar View, but with only part Fig. 21 is a detail view of the lock ever of Fig. 12, in engagement with the parts with which it cooperates.

The operating parts of the lock are arranged within a casing of any suitable material, but preferably of sheet metal of substantial thickness. It consists essentially of a lower or box part, comprising a bottom 10 having

sides

11 and 12, and a top or cover 13. The side 11 is provided at its front end with a ledge 14, and the side 12 with a similar ledge 15 (Figs. 3 and 4), for a purpose to be described.

Closing the end of the casing is a plate 17 (Fig. 7), which, in the formhere shown, is attached to and forms a part of the top plate 13. It serves to close the rear end of the box and protect the key mechanism. Both the bottom 10 and the cover 13 are cut away as at 18, so that the handle of the umbrella 19 (shown in dotted lines in various figures) may rest therein. The top and bottom of the casing are secured together by any suitable means, as by slots 20 in the box and tongues 21 in the top, as is common in lock construction; and by pins "22, or other suitable means. The top 13, where it joins the upright part 17 isprovided with a slot 23 (Figs. 3 and 7) for the reception of a key as will be later described.

Within the casing is slidably mounted an inner section 25, which carries the engaging devices. Various engaging means may be used, but in the form here shown two jaws are employed. One of the jaws 26 is pivoted thereto at 27, and the other 28 is pivoted ihereto at 29. This inner section comprises a top plate 30, a bottom plate 31, and a connecting part 32. These parts may be made in one piece or constructed of separate sheets secured together in any suitable manner as by slots and tongues in the usual way. The bottom plate 31 is made of a width such that it will slide freely within the box 10, but at the same time be guided by the

sides

11 and 12 thereof.

The inner section may occupy either of two positions. When the lock is not in use and the jaws are open, it occupies the projecied position shown in the right hand side of Fig. 1, and in Figs. 2, 3 and 5, in which the jaws are open and extend beyond the casing; when the lock is in use and the jaws closed, it occupies the inner position, as shown in the left hand side of Fig. 1, and in Fig. 4. A spring 33 (Fig. 7), having one end attached to the box 10 by means of a tongue 34 or other suitable means, and the other to a hook 35 formed on an extension 36 of the inner section, tends normally to project the inside section with the

jaws

26 and 28, to the position shown in Figs. 2, 3 and 5.

Jaw 26 has an extension 37, which cooperates with some fulcrum as the pin 22; and the jaw 28 has a similar extension 38, which cooperates with a similar fulcrum, as pin 22 on the other side of the box. Thus, when the lock is open and the inner section is projected by its spring 33, the

extensions

37 and 38, strike their respective fulcrum pins 22, and cause the jaws to open, as shown in Figs. 1, 2, 3 and 5. Stop lugs 40 two on each jaw (Figs. 9 and 10), adapted to move in cut away portions 41 in the connecting plate 32, are so formed and proportioned that when the jaws are open these lugs strike against the rear of the connecting plate 32, thus limiting the opening of the aws.

When the inner section 25, and the

jaws

26 and 28, stand projected by the spring 33, the

rear ends

37 and 38 of the jaws rest against their fulcrums 22 so as to be held open thereby, while the stop lugs 40 rest in slots 41 against the rear of the connecting plate 32, and limit the extent to which the jaws may be opened. The jaws are thus held rigidly when in open position, and can only be moved as the inner section moves into the casing.

The

jaws

26 and 28 have each a cam 42 to the rear of their

respective pivots

27 and 29. When the inner section 25, with the

jaws

26 and 28, is forced into the casing, these cams 42 strike the

respective ledges

14 and 15, and the jaws are camrned thereby to closed position; and when the jaws are in closed position, these cams 42 rest against the edges of the

ledges

14 and 15, and are thus held rigidly in closed position. Thus. when thejaws are open, their

rear ends

37 and 38 rest against the pins 22, and are thereby held in open position, while their stop lugs 40 rest against the back of the connecting plate 32 and prevent their being opened farther than intended; and when the lock is closed, the cams 42 rest against the

ledges

14 and 15 and the jaws are thus prevented from being opened; and they are retained in this position so long as the inner section remains Within the casing.

The inner section 25, with the attached

jaws

26 and 28, is held in closed or locked position by an element termed herein the lock lever. This is shown detached in Fig. 12. It comprises a body portion mounted by pivots 46 in supports 47 attached to or made a part of the bottom 10 of the box. It

is separated a little from the bottom 10, and

is normally held elevated by a spring 48 having one end surrounding a tongue 49 on the bottom 10 and the other resting in a recess 50 of the lever. The lever has the rear end thereof reduced as at 51, and this reduced portion normally lies in the path of the key, so as to be depressed thereby when the key is inserted. Extending from one side of the lever is a lateral extension having a right angled front side 53.

The tongue 36 of the inner section 25 provided with a projection 55 on its under raised, the inside section is thus retained in place and the jaws held closed. g

The front end 51 of this lever 45 which lies in the path of the key and is depressed as the key is inserted,thereby moving the edge 53 of the extension 52 of the lever 45 away from behind the projection 55 on the tongue 36 of'the inside section, thus releasing the inner section, whereupon it will be projected by the spring 33, and the jaws opened.

While the lock is open the key 62 holds the lever 45in depressedposition. In closing the lock theIug 82 on the top plate of the inner section'strikes the cam 81 on the lever 70, causing hook 74 on this lever to be drawn from the notch 67 of the key, thus releasing the key and permitting spring 48 to raise the lever 45 so that face 53 thereof will engage with lug or projection 55 on the tongue 36. v

As the inner section is forced in to close the lock, one side of the tongue 36 passes under a projection 57 formed with or secured to the bottom 10, preventing the tongue 36 being lifted to release the lug 55 from the face 53 of the extension of the lock lever The bottom 10 of the box has secured thereto at its rear end a platej60, forming one side of the key channel. Secured thereto. by any suitable means is a guide plate 61. This plate projects up through the opening 23 of the cover and extends above the same to form a guide for the key. It carries combination devices, and guiding lugs for the key. 1 j

The key 62 is provided on one side with grooves 63 forming, with lugs in the plate .61, varing combinations; and with slots 64,

by which it. is guided by other'lugs in its movements. These combination and guiding devices'form no part ofgthis invention and so ,arenot shown in detail herein. The

key 62 is also providedwith cam edges 65 and 66011 the lower side thereof, and notches 67and68 on the sides thereof. Only certain of these features function in this construction, the purpose of which will be described later. a V

Means are provided for retaining-the key in place when the lock'isopen. A lever 7O is used for this purpose. flThis lever is provided with a part 71 bent into U form to form asuitable pivotal bearing, on the post 72. Another p'art'73, is provided with a hook "74. This hook extends through an the plate 60. above and is guided by a tongue 89 on the plate 60 (Fig. 6)"'and the extension 88 is openingin the plate '60, and into the notch 67 of the key, so as to hold the key in place when the latter is in position in the look. A spring 77 (Fig. 2), having one end secured to a hook 78 on the lever, and the other arm 80 having a cam face 81, which 7 cooperates with .a lug 82 carried by the inside frame, and by which the lever is withdrawn.

When the lock is closed, the key may be withdrawn, but when the lock is open the key is locked in place by the hook 74 of the lever 70. WVhen the key is fully depressed, the notch 67 thereof registers with the hook 7 4,.and when the inner section has moved out held retained by'this means so long as the lock remains open. When the lock is closed,

'the lug 82 on the inner section strikes the cam face 81 of the arm and turns the lever 70 on its pivot 72, thus withdrawing the hook 74 from the notch 67. The lever 45 then raises the key as its edge 53 locks behind the lug 55 on the inner section and the same is closed and the key withdrawn, a so-called anti-pick device is used; This consists of a plate 85 slidably mounted on. the plate 60. This plate 85 is provided with a hook shaped lug 86, which lies at right angles tot-he body ofthe plate,'and with two

extensions

87 and 88. The lug 86 is the spring 77 causes the hook to enter the ,7 notch, thus locking the key in place. It is adapted topass through an elongatedslot in the plate 60 into the path of the cam face 66 of the key 62 and is held therein byfhe hook on the lug86 which engages behind The extension 87 extends adapted to pass beneath the lock lever 45 when the key is withdrawn andthe lever the plate to the right (Fig. n

Insertion of the key causes'the cam face withdrawn, the spring 90 draws the plate to; the right and causes the extension 88 thereof to pass beneath the lock1ever'45,

thus rendering it impossible to depress the lock lever by the insertion of anything by which the end of the lever might be depressed.

Mounted on the inside section is a followup slide 95, which is intendedfto against the handle of the umbrella :is raisedby its spring 48. A springQO, having one end attached to a tongue 91 on 85 and the other secured'to the tongue 89 on the plate 60, draws the plate vother article) when in position, and hold the same closely to the

jaws

26 and 28, thus preventing the same from being withdrawn by unauthorized persons. Inasmuch as the handle of umbrellas differ much in size, this plate is slidably and adjustably mounted on the inside section. The front of this slide is concaved to conform more or less closely to the handle of the umbrella, and its front edge 96 is turned down, so as to present a substantial surface to the umbrella when projected, and to engage with the body of the inner section 25 to force the same inward during the locking operation. Flanges 97, one on either side, extend down the sides of the inner section 25 so as to be guided thereby. The rear end 98 is narrowed somewhat, and a tongue 99 formed on or secured thereto extends through a slot 100 in the top plate 30 of the inner section. The tongue is provided with lateral extensions 101, which are adapted to pass through lateral enlargements 102 of the slot. A spring 103, having one end secured to the tongue 99 on the slide and the other to a tongue 104 on the inner casing, tends to move the plate toward the jaws so as to clamp the handle of the umbrella against the jaws and thus prevent its removal.

A locking pawl 105, pivotally mounted at 106 on the sliding section 25, is used to lock the follow-up slide 95 against backward movement. The slide has one edge serrated as at 107, and a tooth 108 on the pawl 95 cooperates therewith. A spring 111, having one end secured to the pawl at 110, and the other end to a lug 109 on the inner section tends to draw the tooth 108 of the pawl towards the serrations 107. Formed with or attached to the pawl 105 is a lug 112 which passes through an orifice 113 in the inner section, and keeps the movement of the pawl within fixed limits.

The pawl also carries an arm, 114 by which it is operated. Vhen the inner section moves out, the arm 114 engages the post 22 and is turned upon its pivot 106 against the tension of its spring 111, thereby withdrawing its tooth 108 from the serrations 107 of the follow-up plate. The plate is now free to move either in or out without restraint. When the inner section is forced into the casing, the pawl 105 moves therewith, and the arm 114 moves away from the post 22, and its spring 111 moves the tooth 108 into position to engage the serrations 107. The follow-up plate may now move out against the jaws or article held thereby, but it cannot move back, because the tooth 108 of the pawl 105 engages the serrations 107 and prevents its backward movement.

For the purpose of mounting the locks, as upon a rack, the top bar of which is shown at 120, Figs. 2, 3 and 7, the locks are pro- ,vided with suitable fastening devices. Any

suitable means may be employed, but in the form here shown, the plate 13 is provided with an orifice through which a bolt 121, surrounded by a sleeve 122, is passed. The hole in the lower plate 10 is smaller than that in the top, and permits the bolt to pass but not the sleeve. The bolt passes through the top of the rack 120, and is tightened by the nut 123. This causes the sleeve 122 to press upon the bottom plate 10 and clamp the lock to the rack. A second fastening device consisting of a tongue 124, struck from, or secured to the bottom of the easing, may be bent around the edge of the rack as shown in Fig. 7. But, as stated before, these fastening devices are merely illustrative, and any other suitable means may be employed.

Lugs 104 on the top of the lock are for the insertion of number plates thereon.

The beveled edge 65 and the notch 68 of the key 62 have no function in this construction.

Operation Assuming the lock to be open and the parts in normal position, the sliding section stands projected, the jaws are open, and the key is locked in place, by the hook 74 of the key lock lever 70. In using the lock. the umbrella (or other article) is passed between the jaws and moved against the follow-up slide 95. The umbrella is illustrated in this position in Fig. 2. Pressure on the umbrella causes the slide 95 to move back against the tension of its spring 103, which is not as strong as the spring which projects the inner section; the follow-up slide is thus moved back until the flange 96 thereof contacts with the body of the inner section 25. The parts are shown in this position in Fig. 3. Continued pressure now forces back both the followup plate and the inner section, and as they move, the cams 42 on the jaws engage their

respective ledges

14 and 15 of the casing, and are thereby closed. The parts are now in the position shown in Fig. 4 with the umbrella in the rear of the two positions here shown. As pressure upon the umbrella is released, the follow-up plate 95 moves forward under the tension of its spring 103, and forces the umbrella over to the front position as shown in Fig. 7, where the follow-up plate assumes the position shown in dotted lines in that figure. The tooth 108 of pawl 105 engages serrations 107 as soon as the inner section is pushed back by slide Slide 95 is then free to move forward but not backward. The article is now locked in position.

As the inner section moves into the casing, the key lock lever is withdrawn by the lug 82 on the inner section engaging the raised by its spring 48 to the point whereits edge 53 on the projection 52 rises behind the lug 55 carried by the sliding section, thereby locking the sliding section in position. The key may now be Withdrawn."

To open the lock it is only necessary to insert the key and press down thereon. The beveled edge 66 engagesgth lug 86 of the anti-pick device, forcingthe same to the left so as to withdraw the'eXtension'8S from beneath the lock lever 45. Continueddepres sion of the keythen forces the lock lever 45 down to the point whereits edge 53 moves fromfbehind the 111g 55 on the'sliding section. The spring 33 will then fo'rce the inner section outoflthecasing, As itmoves out, the rear ends 3.7 and38 of the

jaws

26 and 28 will engage'the pins 22 and move to open position,asshown in Figs, 2 and 3. Atthesame'time, thekey lock lever 70 will be released by the inner section, and the hook 74 will engage the notch 67 of the key and prevent its'removal.
